Freeing up RAM in Linux

djays — Mon, 27 Jul 2009 10:58:35 +0000

NOTE: Little clarification, this is not needed at all ,as memory is freed when required.

WHY IT MAY BE HELP-FULL: This clears the page-cache , dentires and inodes.

IT’S TRANSLATION : It may be that you are watching a movie or using a Virtual Machine , a resource hungry process has filled up your ram by caching data and the data needs to be continuously removed to make space for new data . This is managed by the kernel.

IF YOU STILL DON’T GET IT: Notice video in your movie hanging (not audio) while your ram gets cached Or your system running a bit slow ?

1) Stop the process consuming loads of memory. (Check System Monitor). 2) Open a terminal with root privileges . 3) Sync 4) echo 3 > /proc/sys/vm/drop_caches 5) echo 0 > /proc/sys/vm/drop_caches

How to install SPECjAppServer2004 on Fedora 8 (JBoss and MySQL)

fastcloud — Thu, 18 Jun 2009 10:26:36 +0000

Last update: August 25, 2009
Installing the SPECjAppServer benchmark software is not trivial. There are a lot of obstacles and the installation and configuration on fedora is really painful. I spent about 14 man-days on this installation – please don’t underestimate the setup!

Goals:
Since I’ve spent a huge amount of time on this installation, this howto mainly aims to preserve my experiences for myself. But if you find it useful you’re invited to use it. This howto shows how to install the SPECjAppServer2004 V.1.08 on a distributed system under test (SUT) with the following components:
- The main application (SPECjAppServer2004 V.1.08) will run on JBoss 4.0.5 GA
- The database will be hosted on a MySQL 5.1 database server
- The emulator (which isn’t actually part of the SUT) will run on Tomcat 6.0.18
All systems will run Fedora Core 8. We’ll use Sun’s JDK 6 Update 13.

Limitations:
If you plan to install SPECjAppServer on another operating system or another application server or with another DBMS or with different software versions, this howto won’t be of great help to you!

Requirements:
You need at least basic linux knowledge, basic knowledge related to computer networks, basic sql and database knowledge and basic J2EE knowledge.

Preparations:
I advise you to setup 4 virtual machines running Fedora Core 8 with static ip-addresses. All machines will need access to the internet and must be able to communicate with eachother. Make snapshots of the fresh installations after you’ve configured the network settings and ssh daemons. This allows you to easily restore your machines using these snapshots in case of failed installations.

You need 4 computer systems:
The SUT which is comprised of
- the system which hosts the database server (DBHOST)
- the system which hosts the application server (APPHOST)
and the system which hosts the emulator webserver (EMUHOST)
and the Driver system which simulates the clients (DRVHOST).

Installation overview:
The systems should be installed in the following order:
A) DBHOST
B) EMUHOST
C) APPHOST
D) DRVHOST

A) DBHOST:
1. Install MySQL
2. Configure MySQL
3. Setup the databases

B) EMUHOST
1. Install JDK
2. Install Ant
3. Install Tomcat
4. Install JBoss and JBoss-SPECJ-Kit
5. Install SPECjAppServer2004
6. Configure the deployment
7. Build and deploy the application
8. Deploy the Emulator

C) APPHOST
1. Install JDK
2. Install Ant
3. Install SPECjAppServer2004
4. Install JBoss and JBoss-SPECJ-Kit
5. Configure the deployment
6. Load the databases
7. Build and deploy the application

D) DRVHOST
1. Install JDK
2. Install Ant
3. Install SPECjAppServer
4. Install JBoss and JBoss-SPECJ-Kit
5. Configure the deployment
6. Build and deploy the application
7. Configure the Driver

####################### Installation steps #######################
Please note: Each step of these installation instructions is required to get the benchmark up and running!

Installation
Installation | Host: DBHOST
Installation | Host: DBHOST | Task: MySQL
yum -y install wget yum -y install mysql mysql-server mysql-devel mkdir /opt/specj mkdir /opt/specj/database chown -r mysql /opt/specj/database

You have to change the default settings of MySQL in order to:
- enable TCP/IP connections (specify port and bind-address)
- enable transactions (use InnoDB instead of MyISAM)
- disable case sensitivity
- allow spaces between function names and the parenthesis

These settings need to be configured in the /etc/my.cnf file. Change the following settings according to your environment:
echo " [mysqld] datadir=/opt/specj/database socket=/var/lib/mysql/mysql.sock user=mysql # Default to using old password format for compatibility with mysql 3.x # clients (those using the mysqlclient10 compatibility package). old_passwords=1 ######################################### # IMPORTANT: bind-address=YOUR-SERVERS-IP-ADDRESS port=3306 ######################################### # lower_case_table_names=1 # MySQL is case-sensitive by default sql-mode=IGNORE_SPACE # Allow spaces between function names and the ( character innodb_data_home_dir = /opt/specj/database innodb_data_file_path=ibdata1:100M:autoextend # Set buffer pool size to 50-80% of your computer's memory innodb_buffer_pool_size=256M innodb_additional_mem_pool_size=20M # Set the log file size to about 25% of the buffer pool size innodb_log_file_size=64M innodb_log_buffer_size=8M innodb_log_group_home_dir=/opt/specj/database/ innodb_log_arch_dir=/opt/specj/database/ innodb_log_file_size=100M innodb_log_buffer_size=64M [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid lower_case_table_names=1 # MySQL is case-sensitive by default sql-mode=IGNORE_SPACE # Allow spaces between function names and the ( character " > /etc/my.cnf
Restart the mysql daemon:
/etc/init.d/mysqld restart

Set the mysql root password:
mysqladmin -u root password YOUR_PASSWORD

Create the database users and databases
mysql -h localhost -u root --password="YOUR_PASSWORD" --execute="GRANT ALL PRIVILEGES ON *.* TO 'specj2004'@'localhost' IDENTIFIED BY 'specj2004' WITH GRANT OPTION; GRANT ALL PRIVILEGES ON *.* TO 'specj2004'@'%' IDENTIFIED BY 'specj2004' WITH GRANT OPTION; GRANT ALL PRIVILEGES ON *.* TO 'jbossjms'@'localhost' IDENTIFIED BY 'jbossjms' WITH GRANT OPTION; GRANT ALL PRIVILEGES ON *.* TO 'jbossjms'@'%' IDENTIFIED BY 'jbossjms' WITH GRANT OPTION; CREATE DATABASE specj2004; CREATE DATABASE jms;"

Download the JBoss-SPECj-Kit to your /tmp directory:
JBoss-SPECj-Kit (download the specj-kit-Oct01.tar.bz2)
Extract the archive and navigate to the directory database/mysql. Copy the file specj.sql to the /tmp directory:
cp specj.sql /tmp/create-specj-tables.sql
Use the editor of your choice (or sed) to replace all occurences of
ENGINE=MyISAM
in /tmp/create-specj-tables.sql with:
ENGINE=InnoDB

Load the sql file:
mysql -h localhost -u root --password="YOUR_PASSWORD" --database="specj2004" < /tmp/create-specj-tables.sql

The installation of the DBHOST is complete.

Installation | Host: EMUHOST
Installation | Host: EMUHOST | Task: Prepare machine
mkdir /opt/specj mkdir /opt/specj/jboss mkdir /opt/specj/SPECjAppServer mkdir /opt/specj/tomcat mkdir /opt/specj/jboss-specj-kit

Installation | Host: EMUHOST | Task: JDK

The first obstacle is that Fedora doesn’t ship with Sun’s JRE and/or JDK. It can’t be installed using yum. You have to download the JDK (*-rpm.bin) manually for your operating system’s architecture from Sun’s website: Download JDK
Download the JDK to the /tmp directory of your APPHOST, EMUHOST and DRVHOST and install it:
cd /tmp wget DOWNLOAD-URL-OF-SUN-JDK-RPM.bin
Execute the following commands to install the jdk:
# remove existing jdk and jre yum -y remove java yum -y remove jdk

cd /tmp # make it executable chmod 755 FILE-NAME-OF-SUN-JDK-RPM.bin
# uncomment/execute the following code if you want to perform a silent installation: # echo "yes" > jdkanswerfile.txt #./FILE-NAME-OF-SUN-JDK-RPM.bin < jdkanswerfile.txt &>/dev/null # shred --remove jdkanswerfile.txt

# otherwise just execute the bin file and follow the instructions. ./FILE-NAME-OF-SUN-JDK-RPM.bin
# set environment variables export JAVA_HOME=/usr/java/jdk1.6.0_13/ echo " export JAVA_HOME=/usr/java/jdk1.6.0_13/" >> /etc/profile

Make sure that Java is installed correctly:
java -version

Installation | Host: EMUHOST | Task: Ant
The next obstacle is ant. Don’t try to install the packages ant and ant-optional using yum. You need to download the ant binaries manually:

yum -y install xml-commons-apis # download ant: visit the ant site and choose another url if this one doesn't work for you wget http://ftp.uni-erlangen.de/pub/mirrors/apache/ant/binaries/apache-ant-1.7.1-bin.tar.gz tar xfz apache-ant-1.7.1-bin.tar.gz mkdir /usr/share/ant cp -r -f apache-ant-1.7.1/* /usr/share/ant/ export ANT_HOME=/usr/share/ant/ export PATH=$PATH:$ANT_HOME/bin # Set environment variables export ANT_HOME=/usr/share/ant export PATH=$PATH:$ANT_HOME/bin echo " export ANT_HOME=/usr/share/ant export PATH=$PATH:$ANT_HOME/bin " >> /etc/profile

You’ll need Junit to install SPECjAppServer. Download the lastest junit jar from Download JUnit (Sourceforge) and rename it to junit.jar. Then, copy the jar into the ANT_HOME/lib directory:
cp junit.jar $ANT_HOME/lib/

Make sure that ant is installed correctly:
ant -version

Installation | Host: EMUHOST | Task: Tomcat
cd /tmp wget http://apache.mirror.clusters.cc/tomcat/tomcat-6/v6.0.18/bin/apache-tomcat-6.0.18.tar.gz tar xfz apache-tomcat-6.0.18.tar.gz cp -r -f apache-tomcat-6.0.18/* /opt/specj/tomcat/ export CATALINA_HOME=/opt/specj/tomcat echo " export CATALINA_HOME=/opt/specj/tomcat " >> /etc/profile

Installation | Host: EMUHOST | Task: JBoss
Download the JBoss 4.0.5 binaries from Sourceforge to the /tmp directory of your machine:
cd /tmp wget http://sourceforge.net/project/downloading.php?group_id=22866&filename=jboss-4.0.5.GA.zip&a=85732289
Unzip and move its content to /opt/specj/jboss/:
unzip jboss-4.0.5.GA.zip mv /tmp/jboss-4.0.5.GA/* /opt/specj/jboss/

Installation | Host: EMUHOST | Task: SPECjAppServer2004
In order to install SPECjAppServer2004 copy the SPECJAPPSERVER2004-ZIP-FILE to the /tmp directory of your machines and unzip it (don’t run the SPECjAppServer2004 installer).
cd /tmp unzip SPECJAPPSERVER-ZIP-FILE.zip cp -rf /tmp/SPECJAPPSERVER-UNZIPPED-DIRECTORY/* /opt/specj/SPECjAppServer/

Installation | Host: EMUHOST | Task: JBoss-SPECJ-Kit
Download the JBoss-SPECj-Kit to your /tmp directory:
JBoss-SPECj-Kit (download the specj-kit-Oct01.tar.bz2)

Unpack the archive and copy its content to /opt/specj/jboss-specj-kit:
cp -rf /tmp/UNPACKED-JBOSS-SPEC-KIT/* /opt/specj/jboss-specj-kit

Installation | Host: EMUHOST | Task: Configure the deployment
You have to modify the following files according to your environment:
/opt/specj/jboss-specj-kit/jboss-MySQL-run.properties
/opt/specj/SPECjAppServer/config/default.env
/opt/specj/SPECjAppServer/bin/setenv.sh

After you've executed the above ant tasks you'll have to change the jndi datasource in the login-config.xml:

sed -i 's/DefaultDS/SpecjJMSDS/g' /opt/specj/jboss/server/SPECjAppServer/conf/login-config.xml
Installation | Host: EMUHOST | Task: Deploy the war-File

Copy the generated emulator war file to the webapps directory:

cp /opt/specj/SPECjAppServer/jars/emulator.war /opt/specj/tomcat/webapps/Emulator.war

Please note the different war-filenames!
Start Tomcat:

sh /opt/specj/tomcat/bin/startup.sh
Open the following URL in your Browser to check if the EmulatorServlet is up:

http://YOUR-SERVERS-IP-ADDRESS:8080/Emulator/EmulatorServlet

The Servlet should produce something like this:



Emulator Servlet seems to work OK

JAS_HOST : YOUR-SERVERS-HOSTNAME

JAS_PORT : 8080

Servlet URL : Supplier/DeliveryServlet

Number of Transactions : 0

Servlet invoked without command specified


The installation of the emulator host is complete.

Execute this target only once and only on the APPHOST. The mysql server on the DBHOST must be running.

ant -DSCALE=5 loaddb

Important: the DSCALE argument is crucial to the setup, since it defines the so called "injection rate" at which the SPECjAppServer2004 benchmark will run. A injection rate of 5 as specified in the statement above is only intended for debugging. 

Read more about the injection rate here: http://www.spec.org/jAppServer2004/docs/RunRules.html#Scaling_Benchmark
You should see something like the following output:

 [java] STARTING loading of tables in the Corp domain...

     [java]     Launching 6   threads to execute LoadCorp.loadCustomers() concurrently

     [java]             Starting thread: Thread[CustomerThread-0,5,main]  For range 1 - 6250

...

After the database has been loaded build the application:



ant

ant run-tests


After you've executed the above ant tasks in order to load the db and build the application you'll have to change the jndi datasource in the login-config.xml:

sed -i 's/DefaultDS/SpecjJMSDS/g' /opt/specj/jboss/server/SPECjAppServer/conf/login-config.xml
Open the following URL in your Browser to check if the SPECJAPPSERVER Application is up:

http://YOUR-SERVERS-IP-ADDRESS:8080/SPECjAppServer/

Click on "Atomicity Tests" on the left side and wait for the results to be presented in the right frame.

If one of the tests fails try to find out why and fix the problems until all three tests passes without errors.

The driver.sh script uses nawk to set/determine JAVA_HOME. This causes problems because nawk is not available for Fedora as far as I know.

Open the file /opt/SPECjAppServer/bin/driver.sh in your favorite editor and look for the line

JAVA_HOME=`nawk -F"=" '{ if ($1 == "JAVA_HOME") { print $2 }}' ${ENVFILE}`

replace it with:

JAVA_HOME=/usr/java/jdk1.6.0_13/jre
Important: Open the file /opt/SPECjAppServer/config/run.properties in your favorite editor and look for a line containing the researchMode property. If the line is missing or commented out add:

researchMode=false

Check the logs in /opt/specj/jboss/server/name-of-your-jas-server/log/server.log for warnings (WARN) or errors (ERROR). Solve these problems. 
Double check that the config files (i. e. default.env, run.properties, jboss-MySQL-run.properties) do not contain spaces after variable values (especially "server-name" and "JBOSS_EMULATOR_SERVER_NAME")!

Problem: JBoss fails to compile the Servlets/JSPs (Jasper Exceptions)

Solution: Copy the tools.jar from the JAVA_HOME/lib directory to the /opt/specj/jboss/server/all/lib directory and restart the application
Problem: SPECjAppServer produces Exceptions related to MDB security (not authenticated TestQueue, BuyerMDB, etc.)

Solution: The datasource configuration is incorrect. Set the correct value:

sed -i 's/DefaultDS/SpecjJMSDS/g' /opt/specj/jboss/server/SPECjAppServer/conf/login-config.xml
Problem: the loaddb target doesn't use the specified injection rate.

Solutions: the DSCALE-argument is case-sensitive. The correct command looks like this: ant -DSCALE=12 loaddb
Problem: Atomicity-tests fail.

Solution: Use the INNODB engine instead of the MyISAM engine. For details see above.
Problem: The driver prints the following stack trace:

Output directory for this run is : ../output/2

Exception in thread "main" java.rmi.RemoteException: Failure in calling validateInitialValues() java.rmi.RemoteException: Invalid initial Order DB State

        at org.spec.jappserver.driver.Auditor.validateInitialValues(Auditor.java:205)

        at org.spec.jappserver.driver.Driver.configure(Driver.java:337)

        at org.spec.jappserver.driver.Driver.(Driver.java:163)

        at org.spec.jappserver.driver.Driver.main(Driver.java:1150)

Calling getLog as master



Solution: It is likely that the database either isn't loaded (correctly) or isn't reachable at all. Make sure that the atomicity tests don't fail. Check every configuration file on DRVHOST in /opt/specj/SPECjAppServer/config/ and make sure that the IP address and credentials of the various databases are set to the correct values.
Problem: The driver throws ClassNotFoundExceptions

Solution: It is likely that you haven't built the SPECjAppServer Application correctly on the DRVHOST. You have to build and deploy the application as described above.
Problem: The driver throws NullPointerExceptions:

sleeptime is 22841 note this is time in excess needed for trigger

Starting Ramp Up...

Exception in thread "Thread-1" Exception in thread "Thread-1" java.lang.NullPointerException

java.lang.NullPointerException  at org.spec.jappserver.driver.DealerEntry.doPurchase(DealerEntry.java:441)

        at org.spec.jappserver.driver.DealerEntry.run(DealerEntry.java:245)

        at org.spec.jappserver.driver.DealerEntry.doPurchase(DealerEntry.java:441)

        at org.spec.jappserver.driver.DealerEntry.run(DealerEntry.java:245)

Exception in thread "Thread-3" java.lang.NullPointerException

Solution: the Property researchMode in DRVHOST/$JAS_HOME/config/run.properties is not set correctly. Set it to false. If it is missing add the line: researchMode=false and restart the driver.
Problem: The driver throws UnknownHostExceptions:

Error: Connection: UnknownHostException: 192.168.0.71

Error: Connection: UnknownHostException: 192.168.0.71

Error: Connection: UnknownHostException: 192.168.0.71



Solution: There are several possible solutions to this problem:
1. The Property researchMode in DRVHOST/$JAS_HOME/config/run.properties might not be set correctly. Set it to false. If it is missing add the line: researchMode=false and restart the driver.

2. It is likely that SPECjAppServer has opened too many connections:
Check the standard output of jboss on the APPHOST for errors. If it says "Too many connections" you need to increase the value of the mysql property "max_connections" in the /etc/my.cnf and restart everything (mysqld, jboss, driver, emulator)
If the DRVHOST or the APPHOST complain about too many connections or too many open files, set the limits to higher values.

Important: it is crucial to set these "limits" on all your machines! You have to restart your SSH sessions afterwards in order to apply the limits!

ulimit -n 999999

ulimit -Hn 999999

echo "

ulimit -Hn 999999

ulimit -n 999999

" >> /etc/profile



3. If this doesn't solve your problem uncomment the line

# rmiCommand = /usr/java/bin/rmiregistry

in DRVHOST/$JAS_HOME/config/run.properties and set the path to the correct (existing!) value and restart the driver.



4. It seems that the driver has a problem resolving the IP-address if the APPHOST is on another network (e.g. DRVHOST = 192.168.0.74, APPHOST = 125.167.0.71).

If this is the case, specify the APPHOST's IP-address (instead of the hostname) in DRVHOST/$JAS_HOME/config/run.properties:

# Url is the url of the SPECjAppServer2004 web application.

Url=http://APPHOST-IP-ADDRESS-GOES-HERE/SPECjAppServer/app?

Restart the driver.


Problem: the driver throws ConnectExceptions:Error: Connection: IOException: java.net.ConnectException: Connection timed out

Solutions: As far as I have experienced these Exceptions may occure during a testrun and don't need to be fixed.
Problem: The driver hangs during startup after printing:Apps server is jboss

Driver Host: 122.123.124.125



What's wrong?

It is most likely that there is a problem with the name resolution. Java's handling of reverse lookups and dns caching in general is discussed very controversely in various mailing-lists. AFAIK the Driver executes the class "ControllerImpl" where the following code InetAddress.getLocalHost()).getHostName() makes a reverse dns lookup for the command `uname -n` (which returns the machine's hostname).

This will lead to problems, if:
the hostname doesn't resolve to a valid hostname or IP-address or if
the hostname actually does resolve to a valid hostname or valid IP-address but the JVM or OS have cached a former dns query which didn't resolve to a valid name in the past.
This might lead to problems, if:
the resolved hostname resolves to a IP-address from another subnet.

Solutions: there are several possible solutions:

1. Make sure that your dns is working correctly.

2. If you know that it is not working as it should and/or if you don't have control over it, just disable the dns for the DRVHOST: Comment out all nameservers listed in /etc/resolv.conf and restart the driver. Warning: Be aware of the negative side-effects! Web browing for instance doesn't work since web addresses can't be resolved any more! But for the duration of the test run, disabling the nameservers is a workaround. 
And don't waste your time playing around with the commandline properties -Dsun.net.inetaddr.ttl=0 and -Djava.net.preferIPv4Stack=true!


Problem: The driver hangs during startup after printing:Calling switchLog as master

RunID for this run is : 1

Output directory for this run is : ../output/1



Solutions:

1. This is likely to be a firewall issue which prevents the driver from connecting to RMI ports. Open all ports on your firewall.

2. There could be an error in your database configuration. Please check if the usernames and passwords in the jboss-MySQL-run.properties are specified correctly.

3. The driver just seems to hang. Depending on your injection rate the driver spends quite a lot of time on initializing the database connections before starting the Dealer Threads. Wait some minutes and check the cpuload on the DBHOST.
Problem: you receive error messages like

WARN  [com.arjuna.ats.jta.logging.loggerI18N] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] Could not find new XAResource to use for recovering non-serializable XAResource

################# Running SPECjAppServer ################# 
Start with a very low transaction rate (i.e. 5). If the benchmark ran successfully, steadily increase the rate (10,25,100,200,...) until the system under test gets overloaded. After each test run, study the results (especially Dealer.summary) in the output folder. If the system was overloaded during a test run, the qos requirements will fail and the system may become unresponsive. In order to determine the maximum transaction rate that can be used by the driver have a look at the Dealer.summary file. The dealer transaction rate in this file usually is a good indicator for the maximum transaction rate that may be used by the driver without overloading the SUT. However, this approximation only works, if the system was overloaded or at least under heavy load before.

How to install apache ant on Fedora 8
fastcloud — Thu, 14 May 2009 07:34:51 +0000
If you just want to run ant, install it using yum:
yum install ant
But if you need to execute the optional ant tasks like scp, junit, etc. you need to “install” ant manually. Please make sure that a java runtime is installed and the variable JAVA_HOME points to the root directory of the java installation.
Save this script as “install-ant.sh” and execute it as root:

yum install wget

cd /tmp

wget http://ftp.uni-erlangen.de/pub/mirrors/apache/ant/binaries/apache-ant-1.7.1-bin.tar.gz

tar xfz apache-ant-1.7.1-bin.tar.gz

mkdir /usr/share/ant

cp -r -f apache-ant-1.7.1/* /usr/share/ant/

export ANT_HOME=/usr/share/ant/

export PATH=$PATH:$ANT_HOME/bin

echo"

export ANT_HOME=/usr/share/ant

export PATH=$PATH:$ANT_HOME/bin:$JDK_HOME/bin

" >> /etc/profile

echo "apache ant has been installed."

exit;
If the script fails to download the tarball visit http://ant.apache.org/bindownload.cgi , coose another mirror and replace the url in the script above.



Beyond Firefox: 10 Other Great Linux Browsers
Tejas Barot — Thu, 07 May 2009 07:09:33 +0000
Firefox has been a reliable browser for me for many years and it still continues to be so to a certain extent. However, over the last few releases Firefox has become bloated and slow in performance that same way IE used to be before we switched to Firefox. The only thing that is stopping me from switching to another browser, is the large number of extensions available for Firefox. Specifically firebug. Since I spend most of my time on a Linux system, over the last few days I have been looking for an alternative Linux browser. Here are 10 of the best Linux browsers out there that can be a decent alternative to Firefox:

5 Compiz Effects That Are Actually Useful
Tejas Barot — Sat, 14 Mar 2009 14:29:15 +0000
Compiz has a lot of nice effects that are mostly useless and I wrote about it before. In my quest to find a work place without distraction compiz effects doesn’t really fit in. Even though examples of compiz effects can be used to demonstrate a superior desktop experience compare to other OS, in reality most of the effects don’t have any practical use other than, “It looks cool”. Few weeks ago when I read about the formation of a new Compiz Council, I was interested to give compiz another try and in the process I actually found some of the effects that actually enhances my desktop experience (unlike wobbly window) and be more productive. Here are five effects that I actually found useful

The Best Screen Capture Software In Linux
Tejas Barot — Tue, 10 Mar 2009 17:26:18 +0000
seldom use the word ‘best’ when it comes to reviewing apps, but when

it comes to Shutter, it really is the best screen capture tool that I

have ever used in Linux.
Shutter (previously known as Gscrot) is just like a swiss army knife

for all your screen capture tasks in Linux. There are plenty of

features packaged into the software: some allow you to perform screen

capture easily and quickly, while others enable you to process the

screenshots more efficiently. I am surprised that it even contains

features that are not found in some commercial software.

How To Transfer Files Easily Among Linux Machines
Tejas Barot — Sun, 08 Mar 2009 05:33:47 +0000
Hi Friends,
Let’s say you’ve got two or more Linux machines in your home (or

office). You want to transfer some files from one computer to another,

what are the ways you can do this?
You can either:
* Use a USB drive

* Use Dropbox

* Use SSH (Secure Shell)
What if there is a small application that is simple, fast and allows

you to send files easily without any configuration or technical

knowledge, wouldn’t it be great?

10 iptables rules to help secure your Linux box
Tejas Barot — Sat, 21 Feb 2009 06:08:55 +0000
Hi Friends,
Today I read nice article about iptables from techrepublic. I like that Article i am sharing with you guys i hope you also Like it.
The iptables tool is a magnificent means of securing a Linux box. But

it can be rather overwhelming. Even after you gain a solid

understanding of the command structure and know what to lock down and

how to lock it down, iptables can be confusing. But the nice thing

about iptables is that it’s fairly universal in its protection. So

having a few iptables rules to put together into a script can make

this job much easier.

Schedule & Automate Tasks In Linux With Gnome Schedule
Tejas Barot — Fri, 13 Feb 2009 16:38:46 +0000
Have you ever done a thing repeatedly on your computer and wished that you could automate it and get it to run on its own?
In Linux, the easiest way to schedule and automate a task is to use the crontab. This is a command line based application that allows you to execute commands or scripts automatically at a specified time/date.
For those who dislike the terminal and command line interface, Gnome Schedule is the graphical equivalent of the crontab. It leverages the power of vixie-cron, dcron and at to manage your crontab file and provide an easy way to schedule tasks on your computer. Be it scheduling a recurrent task or task that happens only once, Gnome-schedule has no problem in handling it.

6 Great Apps to Analyze Your Disk Usage in Linux

6 Great Apps to Analyze Your Disk Usage in Linux



You may own a one terabyte hard disk, but the screen still shows an “Your disk is full” error message whenever you want to install a new application. Does this sound familiar to you?
When I shop for hard disk, I tend to buy one that comes with a large storage space so that I can have ample space to store all my video and music files and to install (and test out) all sort of applications to my system. However, one thing that I found is that no matter how big my hard disk is, it will get depleted very fast. If you are just like me, then it’s time for you to analyze what you have been storing on your hard disk and get it removed to retrieve the storage space.
