R100 HSPA Wi-Fi b/g

sudo ifconfig will give certain into on the ethernet card including an address which is needful.

I could not succeed in getting my Ubuntu machine to connect to the Westell Verizon DSL modem via Ethernet.

One link suggests that I use synaptic manager to install wicd, a GUI network manager, which will DELETE network-manager-gnome and network-manager, so I need to make a careful note of what wicd will DELETE in case I want to reinstall it later.

Wicd is a general-purpose network configuration server which aims
to provide a simple but flexible interface for connecting to networks.
Its features include:
wide variety of settings.
* ability to connect to (and maintain profiles for) both wired and
wireless networks;
* support for many encryption schemes, including WEP, WPA, WPA2 and
custom schemes;
* wireless-tools compatibility;
* tray icon showing network activity and signal strength;
* lack of GNOME dependencies (although it does require GTK+), making it
easy to use in Xfce, Fluxbox, Openbox, Enlightenment, etc.

TODAY I purchased a startech.com ethernet card and stuck it in an empty slot. It claims to have a linux driver, but there are no instructions on how to install it. There is already an ethernet card in the Gateway, and I can tell that there are circumstances where it connects to the router, but still no internet.

These are some links that discuss wicd, just for reference but nothing dramatically helpful or encouraging.

http://wicd.sourceforge.net/moinmoin/Wicd%20on%20Ubuntu

There IS ONE sentence in the above link which is encouraging:
Configuration of Wicd is extremely simple, and automatic for wired clients..

I already have Belkin wireless working, and I could live with that, but it BUGS me that I cannot get ethernet DSL working. Yet, I dont want to do something that will lose my Belkin wifi connection. I was relieved to see that I could REMOVE my Belkin from the USB, play around with Wire and USB configurations (which didnt work) and yet plug the Belkin back in and get my internet connection back.

Since I am a little nervous about what this WICD install will do to my pure Ubuntu Gateway, I have decided to try it out first on my old Compaq Presario Wubi Unbuntu install under windows. If THAT gets trashed, it is relatively easy to reinstall and reconfigure the WUBI. Also, the Compaq does have an ethernet card, so Wubi should be able to connect to DSL through that. I will do that WICD install on the Wubi machine right now. I note that WICD in synaptic manager says WIRED AND WIRELESS NETWORK MANAGER.

I marked it for install, and it mentions that it will install python-urwid and remove network-manager and network-manager-gnome. I am hoping that after the install I will still have wifi connection.

It is now prompting me to choose USERS to add to the netdev group, and there is only one, BRYAN, so I check that, and then click FORWARD. The install finished and I still have wifi connection. So far, so good!

I went to system and looked for network manager, and it says it cannot be found because, obviously, those gnome packages were removed. BUT, when I drop down APPLICATIONS, I now see a new option for Wicd Network manager, and it is lit up to indicate that it senses the Belkin wifi. This is a good sign.

When I click on it, the GUI manager comes up and shows ALL the various wifi channels available in my building (all of which are protected) in addition to my own channel.

I checked off the box on my network to say ALWAYS connect to this and exited the GUI. Then I re-entered the GUI, and to my dismay saw that I lost my connection, and that it needs me to re-enter my WEP key. It offers a confusing array of options which I do not fully understand. But the one which finally accepted my WEP and reconnected me was WEP (HEX 0-9/A-F). I also notice that there is a tab where I can define a wired connection to Eth0. The PREFERENCES tab shows me TWO interfaces, wland0 which is WIRELESS, and eth0 which is WIRED. There are two boxes which I check off to 1.) Always show wired interface and 2.) automatically switch to wired interface whenever available. I am working with desktops but obviously, this would be a convenience for anyone with an Ubuntu laptop.

NOW, I shall reboot, and see if I automatically go back into my wireless connection. If THAT works ok, then I shall connect the cable to the Ethernet, and see if it connects automatically.

It is rebooting now. I suddenly realize the tremendous advantabe of having a test Wubi install on one machine, to try things out before you do them on the pure Ubuntu machine (which would take a LOT more work to reinstall).

FIRST, I let the Wubi machine boot into Windows, to see if I still have my wifi connnection in Windows.

YES, wifi still works in the Windows boot.

NOW, I am booting into Wubi Ubuntu. YES, I have my wifi connection. NOW, to plug the cable from the Westell router into the Ethernet card, and see if it automatically switches. The network icon at the upper right of the desktop “launch pad” says “connecting to wired network.” And the the Firefox broswer works.

Next, to UNPLUG the ethernet cable, plug in the Belkin, and see if it automatically senses and switches or if it FREEZES.

YES, UBUNTU AUTOMATICALLY SENSED THE WIRED CONNECTION AND SHIFTED FROM WIFI TO WIRED!!!

The only problem is that when I clicked on the browser, the machine froze. SO, I have unplugged the Belkin USB WIFI adaptor and am booting JUST with the wired ethernet connection.

I first boot into Windows. Obviously the WIFI is not connected. I click on Start => Control Panel => Network, and enable the LAN local area connection. And yes, the browser works on the wired ethernet under windows.

Next to boot into Ubuntu.

Yes, it senses the wired connection, and Firefox works. Next I unplug the ethernet, and it says NOT CONNECTED on the internet icon. Now to plug in the belkin and see if it switches and works, or freezes.

The WCID install went ok on my Gateway, but unfortunately, it cannot recognize the ethernet card on that machine.

Here is the WCID support forum and what looks like an ICQ channel chat.

I installed ircii in synaptic manager, but it gives no clue as to how to launch it, so then I installed Konversation which is a full gui irc client, and it comes right up, and automatically puts you in a Kubuntu channel.

I have found one use full command when you deal with PCI drivers in linux

lspci which is part of pci-utils

I worked 20 hours straight to prepare an old Gateway tower with 280 gig drive for an Ubuntu 9.10 install. The Gateway was hopelessly unbootable in Windows because of some operating system problem (not hardware problem). I realized that I should drop down to C: and type format, to just reformat the entire drive which took about 30 minutes. I forgot that I should have typed FDISK first, to set up the necessary partitions, but it was too late.

I downloaded an ISO image for GNOME partition and burned it to a bootable CD.

I booted the GNOME partition utility. It took me literally hours to guess at what I should do.

Finally I realized that Ubuntu expects THREE partitions. The first is referred to as ROOT but the actual name you give it in the partition process is simpl “/” (forward slash omitting the double quotes).

The second partition will have NO name, but you will designate its format TYPE as swapfile, and that will become the system swap file.
The third partition is called /home.

I had no idea how much space to allocate, so I gave 512 for root and 512 for swap, and the huge remaineder for /home.

The software warned me that root and swap were too small. Just for the heck of it, I changed root and swap to 5000, and it worked.

Then it took me dozens of tries installing Ubuntu. I had a 2008 Ubuntu disc and a 9.10 disc I had created last week. Time after time, I would boot from each one, say INSTALL UBUNTU, and it would chug away for a long time, and then die with no messages. FINALLY, but why or how I dont know, the 9.10 unstall brought up an Ubuntu desktop with what looked like all kinds of error messages. There were TWO icons on the desktop which I had never seen before. One said EXAMPLES which I never looked at. I was about to give up in dispair when I decided to click on the icon marked Ubuntu. AS IT TURNS OUT, that is the icon which COMPLETES the install process, and it first brings you into its OWN partition software. I cant exactly remember what I did next. I do remember that GNOME partition utility offered me literally 20 DIFFERENT format types to choose from for each partition (one of which is swap-file). I had no clue what to choose. I did some google searching on my other machine (and you NEED a windows machine attached to the internet to look these things up). I discovered that format type ext3 is good for Debian Linux (and Ubuntu is a flavor of Debian) so I went with ext3.

Finally, I had a working bootable pure Ubuntu 9.10 machine.

My next Sisyphean agony task was to connect it to the Internet. The tower already had an Ethernet card. I was informed that IF I connected a cable from the ethernet to the router, then Ubuntu would automatically sense the ethernet connection and configure it. The ethernet board DID light up and pulse when I connected the cable to my Westell router. But Ubuntu never recognized it. Later I read that only certain ethernet cards will be automatically recognized, so I guess the one in my tower was not a compatible one. My next choice was to try and get my Belkin USB WiFi adapter working. I went to ADMINISTRATION -> SYNAPTIC PACKAGE MANAGER and keyed ndiswrapper into the search. I was prompted to place the Ubuntu install cd into my drive. It kept giving me errors. I placed my Belkin adapter install cd in the drive and looked around for the ini driver file, but could not see it. Finally, out of despair, I plugged the Belkin wifi adapter into the USB and LIKE MAGIC Ubuntu recognized it, asked me to choose a connection and enter the WEP key, which I have now done many times with other machines and during the Wubi Ubuntu install on Windows. So now I had a working Ubuntu machine connected to the Internet.

I went to J&R computer store up the street and found a $10 USB 4 gig memory stick by http://www.dane-elec.com which is REALLY cheap. I recently discovered that the Sancor memory sticks that I love actually have a lot of SOFTWARE on them, which only works under windows, AND if you have a password set on the device, then Ubuntu wont even read it.

I had to go into synaptic manager and search on usb for some installs. Again, it was trial and error, and I dont know what finally made it work, but finally, Ubuntu recognized the memory stick.

TODAY, I had to meet my step-son near at Borders Book Store next to Penn Station. This was lucky for me, because while I waited for him, I browsed the computer book section on the second floor. I found a $9 small Linux handbook reference of commands by Daniel J. Barrett (O Reilly publishers) so I got that to practice all the hundreds of Linux commands that I dont know but need to know.

I browse various books on Ubuntu and Mysql.

I found the key thing I needed to know for my next project, to install LAMP (Linux Apache MySQL PhP) on my new Ubuntu desktop.

All one needs to do is enter TERMINAL, and key in

sudo tasksel

(you will be prompted for your system password next)

A task selection window will pop up with many packages available for install, one of which is LAMP. Now here is a mystery that took me an hour to solve. You can arrow down to highlight LAMP, but you dont have a clue in the world as to how to CHECK it for install. Google revealed the secret: YOU SIMPLY PRESS THE SPACE BAR AND IT IS MARKED CHECKED FOR INSTALL. Then you press ENTER and the install proceeds, Apache, MySQL and PhP. You will be prompted for the MySQL admin password.

Next I wanted to install phpmyadmin to administrate mysql, creating databases, tables, etc. I went to SYSTEM-> Synaptic Manager and searched on phpmyadmin. I think there is only one. BUT HERE IS A SECRET. Once your LAMP install finishes, then power down and boot back up; otherwise, certain files will remain locked by processes and the phpmyadmin install will fail.

Once phpmyadmin installs (and you will again be prompted for that pesky password), then you can open firefox and key in http://localhost/phpmyadmin

You will be PROMPTED FOR A USER NAME AND PASSWORD. This is tricky and confusing. You have to key in the user name “root” without quotes, and then give the password that you have been using all along throughout this. Now you are in phpmyadmin, and you can go to Privileges, and create a new user and give him all possible privileges.

Then, I found a $50 book, also by O’Reilly, entitled
“Head First – PHP & MySQL”. THIS book looks like the perfect way to teach myself how to develop php mysql applications which will have proper security (which is a very complex topic).

I didnt purchase that book tonight, because I wanted to come home and see first if I could sucessfully install LAMP and phpmyadmin, which I just now finished.

The Head First book gave me links to try the book on line free for 45 days. Money is kind of tight, so I decided to see how far I can go without any additional purchases, but if I get things working, I will buy the book one day. It is interesting that O’Reilly also offers a link to an on line university which can grant degrees in computer science.

I signed up at Oreilly for a trial access of the electronic version of the above-mentioned book.

Here is something I tried which crashed my Ubuntu. I wanted to copy the introduction to the book, from the OReilly site, and PASTE it into an Open Office Document. The first time Open Office died, and the file was shown as requiring recovery. I did the recovery, opened it again with Open Office Document, and then the whole Ubuntu system crashed. I rebooted, and had to go through a long complicated reconstruct procedure. I thought perhaps I would have to install everything from scratch, but fortunately, Ubuntu repaired itself. Moral to story is paste into GEDIT and save, which I guess eliminates whatever hidden characters are in the webpage which cause Open Office to crash the system.

There, I found a link to download all the source code from the book.

I downloaded the zipped file of all the source code.

Next, I went to the source code for chapter 1. They have a beginnning version (which I guess you make changes to, and then a final version).

I tried to copy and paste report.html to var/www which is where apache wants to find pages loaded from local host. I was not allowed to paste because I do not have superuser priviliges. So, I went to terminal and typed SUDO GEDIT, which gets me into gedit with super powers, so I can now navigate to the unzipped code in my DOCUMENTS in a special folder I created, open report.html, then do a save as to var/www.

THIS WORKED, because now, when I open Firefox and key in localhost/report , it runs the Chapter 1 example webpage.

FOR MY NEXT TRICK, I must figure out how to copy a chapter 1 tutorial image of a dog (fang.jpg) from the location where it unzipped (in a folder in my Documents) and copy it into var/www where I do not have Admin privileges. SO, I open my OReilly handbook of Linux commands and find the CP command. I open a TERMINAL session and key in SUDO CP which I know will executed it with super admin privileges, but NOW I do not have a clue as to what the PATH names are for the file source and destination.

I am permitted to copy fang.jpg from the unzipped file into DOCUMENTS, just to simplify things.

Using PLACES -> COMPUTER, which brings up the FILE BROWSER, I first navigate to home/Documents and I RIGHT CLICK on the fang.jpg image, and click on PROPERTIES which will SHOW ME that the path is
/home/bryan/Documents/fang.jpg (I use bryan as my user name, but that is my step-son’s name). Next I do the same right click trick on any file which is already in var/www such as report.html, and I discover THAT path, which tells me that the command I should issue in TERMINAL is

sudo cp /home/bryan/Documents/fang.jpg var/www/fang.jpg

BUT IT HANGS… NOTHING HAPPENS.

Then I realize that I should close my other applications, because they are somehow LOCKING UP something that the CP command needs. Sure enough, once I close a bunch of applications, the SUDO CP command asks me for the PASSWORD and then copies fang.jpg to var/www

I can now bring up the image by opening Firefox and typing

localhost/fang.jpg

into the browser address field.

NOW that fang.jpg is in var/www, if I once again open Firefox and type
localhost/report.html

the exercise 1 page loads and also shows the picture of the little dog fang.jpg

I still need to copy report.php and style.css from the place where they unzipped to var/www. Since I can launch gedit with sudo and have superadmin powers, I may open them in that fashion and do a save as.

I ran the finished example, hoping that it would actually send me an email.

I realized that I must examine my php.ini and somehow reconfigure it. I went to some pains to locate that file, but did not post notes as I went, and now I must reconstruct what I did. I still have not succeeded in getting the app to actually send an email through php. But I feel it is more essential for me to move on to other lessons in the HEAD FIRST book.

Jahapp, då har även jag tagit ett steg in i framtiden och investerat i en BluRay spelare. Jag har letat länge efter ett billigt alternativ och det slutade med att införskaffa denna spelaren.

Jag passade självklart även på att köpa på mig lite film så jag kan njuta av vår nya leksak direkt. Vi har iof 2st BD filmer sedan innan , Click & Terminator 2, men ändå, man vill ju ändå ha lite nytt när man ändå investerar eller hur?

Här är lilla listan på nyinköpta filmer, klicka på bilderna för att komma till beskrivningen av filmen om ni inte känner igen dem.

Transformers 1 & 2 – Mega Edition (4 disc), Rec, Cloverfield, Hellboy 2, Stargate, Inglourious Basterds

Tyvärr är det fortfarande för dyrt att köpa BluRay (BD) filmer till fullpris, speciellt boxar så som det ser ut nu får det bli att rota runt i billiglådorna och kika efter kampanjer ett tag till. Boxar får köpas på DVD så länge tills priserna sjunker. I stort sett alla filmer som jag köpte nu är på kampanj på cdon, men Inglourious Basterds vill jag ha direkt den kommer så den fick det snällt bli till fullpris. Transformers filmerna är dock ett måste så även den fick det bli köp på direkt, dock till ett lockande specialpris på 399.- Så från och med nu kommer jag inte bara tipsa om köpfilm på DVD utan även på BluRay.

Over at FD Wholesale, we’ve been doing some trials in our R&D department bonding Annex M tails together and we’ve been able to get throughput normally associated with leased lines. We’re roughly 1.5Km from our local exchange, and when bonding 2 lines, the total sync rate was 26.7Mbps down and 4Mbps up. When we bonded 4 lines, we obtained 56Mbps down and 8Mbps up.

The applications for this are wide ranging. Consider having a client who lives 5Km+ from their local exchange. 1 DSL would offer them little throughput to sustain a number of users. Aggregate 2 or 3 together and suddenly they can start to look at IP applications that may improve business processes such as SIP or Video conferencing. Another example may be where a client can’t gain wayleave agreement to obtain a fibre run. In this instance, they can have a bonded Annex M service offeirng up to 80Mbps down and 10Mbps up. Obviously these are headline speeds and are dependant on quality of copper and line length, but in all but the worst circumstances, a bonded Annex M service can start to become a compelling alternative to EFM or FTTC. Using the BE network, this is also available immediately, nationwide. No waiting for 2012 to have a coverage of c.300 exchanges.

Currently this is something that all our channel partners are utilising, as it gives them a cost effective alternative to a leased line. Based on the Cisco proprietory protocol, traditionally the stumbling point has been the high initial price point associated with the routers. However, we’ve been conducting some trials with a manufacturer called Virtual Access using their GW7000 boxes, and they’ve been very successful in terms of throughput and stability. However, even more compelling is the fact that they lower the initial price point of the solution to sub £500.

Personally I feel that bonding Annex M tails, at the core is a lot more resilinet solution than trying to aggregate them at the client end, using an external aggregator, as it means that there is little overhead, lower packet loss and less latency. In my opinion, the main thing to take away from this is that even though fibre will still have it’s uses, the applications for DSL are ever increasing. Whereby traditionally a leased line was the only method available to provide large amounts of throughput, the landscape is ever changing to incorporate DSL.

I am learning how to write pci and Ethernet driver . I will post here the success and problem that I came across while learning

Simple coder to detect the pci device in the pci bus

In the above code to probe and vendor or device ID use the PCI_ANY_ID so it will detect any PCI device on the bus.

Meeting hari senin kemarin ternyata membawa berkah yang luar biasa buat aq (alah,,hahha). Selain dapet kue2 yang maknyus, pengetahuan tentang karakteristik modul GBE ALU pun semakin terbuka. Untuk pengetesan BB PE IP MPLS yang sudah menghabiskan badget puluhan juta itu ternyata blm berhasil sodara2. Jalur transmisi yang dibuat via SDH ALU dengan kapasitas 1 G, ternyta belum tmbus.

Kami memakai card tipe ISA-ES16, dan untuk di aksesnya (yg bkalan di colokin ke router) adalah modul GETH-AGR. ISA-ES16 sendiri bisa mendelivere trafik sebesar 16 x STM 1 alias sekitar 2.5 G. GETH-AGR punya 4 port akses dan bisa mengeluarkan trafik sesuai cross conent yang dibuat, tergantung desainnya. Kombinasi2 yang bisa diterapkan adalah sebagai berikut:

1. Port 1 & 2 kapasitas 1 G dimana ini setara dgn 7 VC4 / STM-1 –> berarti 2 port dah ngabisin 14 VC4, so tinggal 2 VC4 lagi kan.. (sesuai kapasitas ISA-ES16 td). nah 2 VC4 itu bisa kita keluarin di port 3 & 4 dengan masing2 BW nya 100 Mbps (1 VC4)
2. Kombinasi yang laen sesuai kebutuhan, yang pasti prinsipnya ke -4 port tersebut cuma dijatah BW sebesar 16 VC4 ato 2.5 G. Apabila kita memaksakan mengkonfigure ke tiga port sebesar 1 G, maka port yg ke-3 tidak akan bisa mengeluarkan trafik 1 G, tp hanya 2 VC4 = 288 Mbps

Kemudian untuk pembuatan cross connect nya juga membutuhkan teknik tambahan, tidak seperti jika kita mendeliver service TDM. Setelah kita selesai buat XC di sisi SDH nya, kita juga harus membuat crosconnect di card GBE nya. InsyA laen kali klo ad waktu aq share ya caranya gmn.

Okay…moga bermanfaat ya…caooo…

เอชพี (Hewlett-Packard) ประกาศซื้อกิจการบริษัททรีคอม (3Com) ผู้จำหน่ายระบบเครือข่ายคอมพิวเตอร์รายใหญ่ด้วยเงิน 2,700 ล้านเหรียญสหรัฐ ถือเป็นความเคลื่อนไหวครั้งล่าสุดของผู้ผลิตคอมพิวเตอร์พีซีอันดับ 1 ของโลกในการขยายอาณาจักรในกว้างไกลยิ่งขึ้น

เอชพีระบุว่าจะซื้อหุ้นทรีคอมในราคา 7.9 เหรียญสหรัฐต่อหุ้น คาดว่ากระบวนการควบรวมจะแล้วเสร็จภายในครึ่งปีแรกของปี 2010 อย่างไรก็ตาม เอชพีไม่เปิดเผยว่ามีแผนปรับโครงสร้างองค์กรหรือลอยแพพนักงานทรีคอมอย่างไรในแนาคต โดยขณะนี้พนักงานทรีคอมมีจำนวนทั้งสิ้น 5,800 คนทั่วโลก

ทรีคอมนั้นเป็นบริษัทที่มีผู้ร่วมก่อตั้งคือ Robert Metcalfe หนึ่งในผู้คิดค้นมาตรฐานเครือข่าย Ethernet ที่ใช้งานในระบบคอมพิวเตอร์ทั่วโลก โดยทรีคอมนั้นถือเป็นบริษัทที่รุ่งโรจน์มากในยุคปี 80-90 เคยทำสถิติมูลค่าหุ้น 100 เหรียญในปี 2000 แต่แล้วฟองสบู่ก็แตกลงตามวิกฤตเศรษฐกิจ จนในช่วงหลายปีที่ผ่านมา มูลค่าหุ้นของทรีคอมนั้นอยู่ที่เฉลี่ย 5 เหรียญ
การเทกโอเวอร์ทรีคอมของเอชพีครั้งนี้เกิดขึ้นหลังจากการเจรจาซื้อขาย บริษัททรีคอมกับกลุ่มทุน Bain Capital Partners และพันธมิตรสัญชาติจีนอย่าง Huawei Technologies ล้มเหลว ซึ่งดีลหลังนั้นล้มเหลวเพราะความหวั่นเกรงเรื่องความมั่นคงของชาติ เนื่องจากทรีคอมนั้นมีบริษัทลูกที่ดำเนินธุรกิจรักษาความปลอดภัยระบบ คอมพิวเตอร์ (Tipping Point) ทำให้ทางการสหรัฐฯหวั่นเกรงว่าการที่บริษัทจีนเข้ามามีส่วนบริหารทรีคอมอาจ เป็นภัยต่อความมั่นคงขององค์กรในสหรัฐฯ

การ เข้ามาของเอชพีจึงไม่มีข้อครหาใดๆเหมือนดีลกับหัวเว่ย โดยสิ่งที่เกิดขึ้นคือเอชพีจะกลายเป็นคู่แข่งของซิสโก (Cisco Systems) พันธมิตรเก่าแก่ของเอชพี ซึ่งเป็นผู้ให้บริการเครือข่ายคอมพิวเตอร์รายใหญ่อย่างเต็มตัว

ที่ผ่านมา เอชพีนั้นมีผลิตภัณฑ์เครือข่ายคอมพิวเตอร์ของตัวเองนาม ProCurve เช่นกัน แต่มีสัดส่วนทำรายได้ไม่ถึง 1% ของยอดขายรวม 83,600 ล้านเหรียญตลอด 9 เดือนแรกของปีการเงินเอชพีที่ผ่านมา

ยังไม่มีรายงานนโยบายการทำตลาดของทรีคอมภายใต้การดูแลของเอชพีในขณะนี้

ตาม คาด มูลค่าหุ้นของเอชพีลดลงราว 35 เซนต์ ปิดที่ 49.65 เหรียญ ขณะที่หุ้นทรีคอมพุ่งกระฉูด 1.98 เหรียญ คิดเป็นสัดส่วนเพิ่มขึ้น 35% ปิดที่ 7.67 เหรียญหลังการประกาศซื้อบริษัทโดยเอชพี

Sun VirtualBox. I have Ubuntu and Win7 RC installed inside it. But you can install all kinds of OS’s, mess with them all you like. That way you aren’t limited to just that version Linux, you could install them all, as long as you have the hard drive space.

But now, from what you tell me and what I have read in google (and I wrote a long support question to Startech, who will probably get back to me next week about their Ethernet card which is only $10, and claims to have Linux drivers).

Also, here is a funny true story. Last week, I thought my stepdaughter was telling me that she has an old tower she doesnt want, and I could wipe out the drive with a pure Ubuntu install. She just called to say her husband was bringing it over with a monitor (which I can keep)…. but when I told her my plans, she was horrified, and said that she wants me to CLEAN UP THE VIRUSES and give it back to her, because right now it will only boot in F2 Safe mode. Ha ha! I am glad I asked, and she should have been less vague and cavalier. But now I have little fear about plugging the cable from the Westell jack into the ethernet jack. Besides, it stands to reason what when any software is about to modify anything, it would prompt.

Although, here are two things I didnt understand about Verizon DSL. Once, I changed the password on the Verizon email account, and that DISABLES the modem that is connected to that account, and a service technician must do a number of things over the phone to restore the DSL service. That was a painful lesson. Another time, DSL was down, and I though I should take a pen and hit the reset button on the Westell. I didnt realize that doing that WIPES OUT EVERYTHING in the Westell, and you have to get on the phone for an hour with a technician to reset the Westell. So perhaps those two horrible experiences contribute to my fear and hesitancy to mess with the Westell.

Old saying: once burnt, twice shy. Plus, if it ain’t broke dont fix it. Years ago we had our first home DSL with AOL. My stepson who was only 13, decided one day to reinstall AOL from a new diskette that came in the mail. That WIPED OUT THE DSL, and AOL was NEVER able to restore it, and their tech dept was not too worried about restoring it.

Thanks for your feedback, it did help! I wasn’t hesitant about hooking up an Ubuntu machine. I am just scared to death of Verizon and Westell. I did take the courage to go into the Westell setep to enable Wifi with WEP key protection. 3 years ago in my 27 story high rise, one could pick up all sorts of unprotected wi-fi. NOW, all the channels are protected and one is even named “GET AWAY!!!”. People began to realize that other people could steal bandwidth.

I would like to close by suggestion something that I think Thomas Jefferson would suggest were he alive today: namely FREE PUBLIC WIFI in every city. Jefferson asked that only two accomplishments be mentioned on his tombstone: that he signed the Declaration of Independence, and that he founded the University of Virginia. Jefferson suggested free education for all, which in his day seemed like a strange idea. After all, education was only for nobility and the wealthy. The peasant farmers and laborers didnt need to know how to read. But Jefferson realized that unless ALL were educated, even laborers and farm workers, then there could NEVER be a government “of the people and by the people.”

What does this have to do with free wi-fi, you ask? Everything. Today, computer illiteracy is the new danger. In 1960, my mother had to fight to get me a $2000 World Book encyclopedia so I could do my homework in 6th grade, because there were no libraries close by. But today, who buys an encylopedia, when there are search engines and things like Wikipedia?
Every child NEED computers and internet access. True there are dangers and abuses in chat rooms etc, but then there are dangers in the postal mail system. That does not mean we should do away with the post office. It means that we should find safe guards and establish punishments for crimes committed using the U.S. mail or the internet. We must make it a crime to shout FIRE as a joke in a public auditorium, but we must preserve freedom of speech. And if there is ANYTHING at all in this world which will unify all peoples and nations and creeds it is the communication and understanding provided by the Internet. I know because I have a friend of 10 years now in Tehran Iran, who loves Plato and Tolstoy and Dostoevsky and everything that is western and free.

In a very poor neighborhood in one large city in India, where there are many high tech computer firms, as an experiment, they installed many rugged computer terminals in the alley ways where homeless street children dwelt. Those children quickly learned how to be very

One member answered my question:
Why would plugging a PC, no matter what OS is installed on it, into a modem/router change it? So no I wouldn’t worry about the Westell.

My reply:

Thanks! That’s just what I needed to know. But, obviously, I am not technically versed. So what is OBVIOUS to you may not be obvious to me.

A professor of Russian language, in the 1970s once said to me “There is no such thing as a foolish question, for IF it is a question in your mind, it is a LEGITIMATE question. There are only foolish answers.” Beginners should be encouraged to ask questions, and not ridiculed, for that is how they learn. And those who are fortunate enough to have expertise and experience should not gloat in their knowledge as if it were wisdom.

I once mentioned to an examining physician something very obscure and little know, about the anastamosis (joining) of a one vein to the left renal vein which is totally different on the right. He was astounded and asked how I could possible know that, not being a physician. I explained that all one has to do is read, and remember a fact, and the only difference between a physician and a plumber, is that plumbers still make house calls, but physicians do not.

Plus, if I had 5 routers, and 3 providers, and money flowing out my kazoo, I would just plug the cable in and see what happens. But, if something DOES go wrong, then since I only have one router and one provider, then I must spend hours on the phone with tech support, or, if that fails, spend days waiting for a technician to show up from Verizon.

Oh, by the way, I found a free beginners manual in PDF, on Ubuntu, which also mentions that IF the Ubuntu machine has an internet card, THEN connecting it to the router should give instantaneous internet access.

And, this is a bit off topic, but I spent much of last night experimenting with that Ubuntu chat program EMPATHY. When I initially clicked on Empathy, it launched a wizard asking me first if I wanted a Jabber account, and then asking me if I want to add AIM, MSN, Yahoo, ICQ, etc.

I only added Yahoo. Later, I tired to add other things and could not see how to get back into that wizard dialogue. I googled and found other posts suggesting that there was some problem. I UNINSTALLED REMOVED and reinstalled EMPATHY, but still no wizard. THEN I discovered that F4 will bring up a window to ADD other chat programs (which is not intuitively obvious to a beginner). I was pleased to see that my Wubi Ubuntu install is stable enough to remove and reinstall Empathy without crashing things.

I am very curious to explore the limits of the Wubi install on a Windows machine. Tonight I will have that old tower, and do a pure Ubuntu desktop install, and first I will try the wrapper technique with a Belkin Wi-Fi, and later I will experiment with the cable from the Ethernet to the router. I was a bit confused as to whether I should install Ubuntu DESKTOP or Ubuntu Server, but reading up on it made me realize that I am better off with the Desktop, because that gives the most GUI, and then ADD LAMP (Apache, MySQL, PhP) with the synaptic manager, since that is all I really want anyway and I will not use the machine as an actual server to other clients.

Here is the post that I want to submit to

I just spent a LONG LONG TIME typing this post into the above forum and it disappeared. SO, I am composing it HERE first in my BLOG so that it will NOT disappear.

I use Verizon DSL with a Westell 327W Router. I have one Dell Windows XP hard wired to the router, and second XP connected via WiFi with a Belkin USB adapter.

I want to take a 3rd computer, an Ubuntu desktop install, and use a startec.com ST100S 10/100 mbps Ethernet PCI, which claims to have a Linux driver.

BIG QUESTION: If I do succeed in attaching the Ubuntu Desktop through the startech ethernet, is there any danger that the Westell modem will somehow be reset or reconfigured or disturbed so that I lose Internet and have to wait for a Verizon technician to show up and fix things. IF there IS such a danger, then I will go with wifi for the Ubuntu desktop.

I looked at all the WiFi and Ethernet products at J&R Computer World and found only ONE that mentions Linux, and it is 10/100 MBPS Ethernet PCI ST100S Netware ODI for DOS Linux

Here is the support question I submitted to

I want to do an Ubuntu Install, use your ST100S 10/100 MBPS Ethernet PCI, and connect it to my Westell modem running Verizon DSL and working fine with my Windows machine. 2 questions: 1) Can I easily do the unstall in Ubuntu. 2) WILL MY WESTELL MODEM BE ALTERED IN ANY WAY, by the install,.. am I in danger of losing all internet?
Can you suggest any other product or USB Wifi that well help me connect an Ubuntu Linux install to Internet through my Westell 327W Verizon Modem?

If I can make it work, I will spread your Company’s name and praise in many Ubuntu Forums!

P.S. – Ubuntu looks so promising to me that it is hard to believe not one single WIFI or Ethernet product mentions ANYTHING except XP Vista Windows3 etc.

The additional Ethernet port was obtained by installing a $12 Startech ST100S 10/100 Mbps Ethernet PCI Card from amazon.com. This card uses a RTL8100C chip and works with the 8139too Linux driver already being used by the motherboard Ethernet interface.

Just saw that Hewlett Packard is acquiring 3Com for deal valued at around $2.7 billion.

3Com will also provide Hewlett Packard with its TippingPoint portfolio which is a network security system.

From TechCrunch:

HP says the acquisition will further its data center strategy “built on the convergence of servers, storage, networking, management, facilities and services.” The acquisition of 3Com also help to expand HP’s Ethernet switching offerings, add routing solutions and significantly strengthen the company’s position in China thanks to 3Com’s strong presence in China.

From CNNMoney.com:

3Com took in $1.3 billion in revenue last year on its networking and securities solutions products. The Marlborough, Mass.-based company mostly does business with corporate clients, and its H3C networking unit is a market leader in China.

HP  said it made the acquisition to expand its networking solutions offerings and to “significantly strengthen the company’s position in China.”

Over the past year, HP has increased its services and business solutions business exponentially, catapulted by its $13.9 billion acquisition of services firm EDS last year.

From InformationWeek:

3Com will bring a wide-ranging portfolio of network switching, routing and security solutions to HP. The technology will boost HP’s already potent networking offerings, which are centered in HP Procurve.

“By acquiring 3Com, we are accelerating the execution of our converged infrastructure strategy and bringing disruptive change to the networking industry, HP executive vice president Dave Donatelli said in a statement.

HP’s converged infrastructure architecture, announced Nov. 4, essentially creates a one-stop data-center shop. It packages HP’s compute, storage, networking offerings into a highly virtualized bundle which can be centrally managed.

That move came shortly after Cisco linked up with EMC and VMware in a partnership which tightly integrates storage alongside easy-to-manage virtualized data-center bundles called V-Blocks.

Vitesse-Based Gbit Ethernet Switches Support PoE

Silicon Laboratories and Vitesse Semiconductor have released multiple reference designs to enable easy upgrades for Vitesse-based Gbit Ethernet switches. These upgrades will allow the Gbit Ethernet switches to support the recently ratified IEEE 802.3at Power over Ethernet (PoE+) standard. Two new reference designs combine Silicon Laboratories’ highly integrated, energy-efficient PoE Power Sourcing Equipment (PSE) controllers and the Vitesse E-Stax and Sparx Gbit Ethernet switching chipsets for 24-port stackable and five- to 24-port workgroup and desktop switches, respectively.

The first joint design is a PSE daughtercard for E-Stax and Sparx-II switches. The plug-in daughtercard features an isolated I2C interface, self-contained operation from an isolated PoE supply (54V nom.) and efficient thermal profiling. The design supports 24 ports at up to 30W each with full IEEE 802.3at compliance. Multiple daughtercards can interoperate on a single I2C host interface for high port-count scalability. Switch-host software integration and an independent PoE power supply enable a single-switch motherboard design appropriate for PoE and non-PoE SKUs.

The second design is a single-motherboard implementation for the Sparx-G8e switch. Supporting eight ports of PoE (15.4W) or PoE+ (30W) capability and Vitesse’s web-based configuration and power-management GUI, this complete PoE-enabled switch is intended for applications such as desktop switches, VoIP telephony, wireless-access points, industrial networking, video surveillance and security systems.

Both reference designs include schematics, bill of materials and comprehensive PCB layout files for fastest time-to-market and design success. Silicon Labs’ Power Manager Software Development Kit (SDK) allows system developers to quickly develop highly differentiated PSE systems with sophisticated power-management features to minimise power-supply costs and maximise energy efficiency. Based on Silicon Labs’ Si345x PoE+ PSE controller family, designers can take advantage of real-time power-measurement capabilities.

The Si345x incorporates high-precision current and voltage-measurement capability to monitor the power consumed by each port, enabling systems to maintain tighter control of power allocation, which translates to smaller power supplies and lower supply overhead and gives system administrators visibility into how much power is allocated to and consumed by each port in their network. Link layer discovery protocol (LLDP) power management algorithms are implemented at the system level, enabling dynamic power allocation. Vitesse’s E-Stax products feature its Vstax cabling technology, a scalable high-speed 24+4 port configuration, a performance-driven architecture and a rich integrated feature set to deliver low-cost Gbit Ethernet for OEM and ODM customers.

The Sparx unmanaged and smart web-managed switches eliminate the need for external processing and memory found in fully managed switches, allowing developers to deliver a smart switch with advanced Layer-2 capabilities at a fraction of the cost of a fully managed switch. Sparx switches also include Vitesse’s Ecoethernet technology, which delivers green savings equivalent to more than 400mW per port. Both product families are ideal for Carrier Ethernet applications as they support synchronous Ethernet with SSM according to ITU-G.8264/Y.1362 and offer fast protection switching with switching times significantly below the 50ms telecom requirement.

Basler Cameras Include Power Over Ethernet

The Basler ace camera series has been launched at the Vision Show in Stuttgart. The cameras measure 29 x 29mm and include Power over Ethernet. They are designed to meet the cost demands of analogue camera users while offering all of the technological advantages of a digital camera. The high-performance FPGA used in the cameras includes features such as several automatic parameter-adjustment functions and optimised software-trigger function for high-speed triggering via the GigE bus.

The Power over Ethernet option makes connecting GigE cameras less complex and cheaper by eliminating the need for a second cable. Basler provides its pylon software package, a free SDK and Viewer Tool including sample programs to help users get started quickly. The pylon software package runs on Windows and Linux and can be used with all common development environments. The ace series will initially consist of four camera models in monochrome and colour, with resolutions from VGA to 2megapixels and featuring a C-mount adapter. All cameras are equipped with a CCD sensor.

The use of distributed control, a.k.a. fieldbus systems, has become increasingly important not only for all kinds of industrial applications and automation tasks, but also for medical, maritime, avionic and military devices. Any fieldbus system will save costs over centralized control by reducing wiring, increasing reliability and improving maintainability.

One fieldbus system in particular, Controller Area Network (CAN) including higher layer protocols based on CAN such as CANopen and DeviceNet, is still an increasingly popular choice for the North American market due to its high level of data transfer reliability. CAN was originally designed for use in automobiles, but quickly found its way into any application where microprocessors need to communicate with each other and that can include small-sized applications such as medical devices up to complex tasks as robotics or satellites.

According to Wilfried Voss, author of ‘A Comprehensible Guide to Controller Area Network’ (See http://www.copperhillmedia.com/CANBook.html): “During the years, since the publication of the CAN standard in 1986, there has been the quest to create and establish better and faster field bus technologies, but none of them has managed to replace CAN as of yet and it will stay that way until new technologies will be able to match the excellent price over performance ratio of CAN.”

The automobile industry is currently exploring and, to some degree, using systems such as FlexRay, LIN and Time-triggered CAN, however, when it comes to industrial automation the main focus is definitely on Ethernet-based technologies. Ethernet supports a data rate of up to 100 Mbits/sec, but does lack the real-time capabilities and very short error recovery times of CAN. These short-comings have been resolved with the emergence of industrial Ethernet based protocols.

Dr. Werner Schulze, Managing Director of esd electronics in Germany, considers the CAN 1 MBit/sec baud rate only a marketing problem, not a technical problem: “Just because we are able to build a race car does not mean you’ll do your shopping in it, does it? You still see people doing their everyday business in regular cars, and it will be like this in the future, too. I believe, it’s the same with CAN and Ethernet.”

A current problem with Ethernet-based fieldbus technologies is the great number (currently 20+) of available protocols, including Powerlink, Ethernet/IP, EtherCAT, Modbus/TCP, ProfiNet, and more, just to name the most popular (or better: most promoted) choices. It is nevertheless safe to predict that the use of Ethernet-based protocols will increase significantly in the years to come, but only a few choices will prevail.

“CAN will remain popular in large vehicle applications”, predicts Wilfried Voss, “especially due to the strength of the SAE J1939 protocol and activities such as the British ‘Future Rapid Effects System’ (FRES) for military vehicles, which uses MilCAN. Ethernet technologies will begin to conquer the automation market slowly, starting with applications that benefit from high-speed processing, for instance, robotics. I believe that Ethernet/IP will play a strong role in the North American market. European technologies like Powerlink and EtherCAT will have some share of the market, but as long as the Ethernet-Powerlink Specification Group (EPSG) is not able to adjust their marketing activities for the North American market, I would favor EtherCAT. The EtherCAT Technology Group, with office in the US, seems to understand the importance of the North American market.”

Copperhill Media Corporation, the leading publisher of technical literature on CAN technologies, created an Online survey to shed a light on the market’s preferences. As of September 9, 2008 more than 160 engineers have contributed to the current result, which favors EtherCAT (40%) over Ethernet/IP (33%).

My mom said she wants to go to Hong Kong this summer. I say no. Why? Because there’s no stupid Internet there at my grandmother’s place. Sure I can catch some Wifi waves off of some neighbors, but they shut off their wireless at night for some reason. So, if I do go, wish me luck without some Internet access (oh wait, my cousin has Internet. But I stay at my grandmother’s place. Darn it!). I’ll also try to post some stuff at my cousin’s apartment where they have Internet via Ethernet cables (if I go). I probably won’t go, but just in case…
