How do I sync data between two Load balanced Windows 2003 servers?


For UNIX/Linux server you can use rsync command to keep data sync'd between two servers. rsync also works under Windows NT/2003 server but it will take lots of time to setup.
For Microsoft Windows 2003 server use robocopy tool, to sync files between two windows server. You can download robocopy.exe and other files from Windows 2003 Resource Kit Tools set.
Once tool is downloaded, install the Resource Kit. By default robocopy located at c:\Program Files\Windows Resource Kits\Tools\robocopy.exe. Now let us assume that you want to sync d:\Inetpub\wwwroot\ directory between two Windows server. First create hidden share on www2 (secondary server)
  1. Login to www2
  2. Select d:\Inetpub\wwwroot\
  3. Right click > Properties > Sharing tab > Share this folder > Add $ at the end of share name and save the changes.

How do I use robocopy command?

=> Login to primary server (www1)
=> Click on stat > run > type cmd
=> At command prompt type command:
c:>"c:\program files\windows resource kits\tools\robocopy.exe d:\inetpub\wwwroot www2\\inetpub\wwwroot\"ALTERNATIVELY, use IP address of www2 server :
c:>"c:\program files\windows resource kits\tools\robocopy.exe d:\inetpub\wwwroot 202.54.10.200\\inetpub\wwwroot\"robocopy has many more options and lots of other information available in Robocopy.DOC file.

How to sync data between 2 servers automatically


Have you ever wanted to know how to easily synchronize the data between multiple servers automatically?

In this article I’ll explain how to setup 2 Linux servers to automatically synchronize data between a specific directory on each server. To do this we will use rsync, ssh key authentication, and a cron job.
Let’s call the 2 servers ‘SOURCESERVER’ and ‘DESTSERVER’ for
SOURCESERVER = Source server (the server we’re connecting from to upload the data)
DESTSERVER = Destination server (the server we’re connecting to receive the data)

Part 1 - Setting up SSH key authentication

First, we need to make sure the DESTSERVER has the ability to use key authentication enabled. Find your sshd configuration file (usually ‘/etc/ssh/sshd_config’) and enable the following options if they are not already set.
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys

If you edit the file be sure to restart sshd afterwards.
# /etc/init.d/sshd restart
Next, on the SOURCESERVER we will create the public / private key pair to be used for authentication with the following command.
# ssh-keygen -t rsa
*Note: Do not enter a passphrase for this, just hit enter when prompted.
This should create 2 files, a public key file and a private key file.
The public key file (usually [homedir]/.ssh/id_rsa.pub) we will upload to the DESTSERVER.
The private key file (usually [homedir]/.ssh/id_rsa) we will keep on the SOURCESERVER.
*Be sure to keep this private key safe. With it anyone will be able to connect to the DESTSERVER that contains the public key.
Now we will plant the public key we created on to the DESTSERVER.
Choose the user account which you will use to connect to on DESTSERVER, we’ll call this user ‘destuser’ for now.
In that account’s home directory, create a ‘.ssh’ subdirectory, and in that directory create a new text file called ‘authorized_keys’. If it already exists, great, use the existing file.
Open the ‘authorized_keys’ file and paste in the contents of the public key you created in the previous step (id_rsa.pub). It should look something like the following
ssh-rsa <lots and lots of characters…> [email protected]
Save the file and change the permissions to 600 for the file and 700 for the ‘.ssh’ directory.
Now to test that the keys are working.
From the SOURCESERVER try logging in as normal using ssh to the DESTSERVER.
# ssh [email protected]
If all is working you should not be prompted for a password but instead connected directly to a shell on the DESTSERVER.

Part 2 - Creating the rsync script

Now for the rsync script.
I use a simple script such as the following
——————————————-
#!/bin/bash
SOURCEPATH=’/source/directory’
DESTPATH=’/destination’
DESTHOST=’123.123.123.123′
DESTUSER=’destuser’
LOGFILE=’rsync.log’
echo $’\n\n’ >> $LOGFILE
rsync -av –rsh=ssh $SOURCEPATH [email protected]$DESTHOST:$DESTPATH 2>&1 >> $LOGFILE
echo “Completed at: `/bin/date`” >> $LOGFILE
——————————————-
Copy this file into the home directory of the sourceuser on the SOURCESERVER
and modify the first 4 variables in the file.
SOURCEPATH (Source path to be synced)
DESTPATH (Destination path to be synced)
DESTHOST (Destination IP address or host name)
DESTUSER (User on the destination server)
Save it as something like ‘rsync.sh’
Set the permissions on the file to 700.
# chmod 700 rsync.sh
Now you should be able to run the script, have it connect to the DESTSERVER, and transfer the files all without your interaction.
The script will send all output to the ‘rsync.log’ file specified in the script.

Part 3 - Setting up the cron job

Assuming everything has worked so far all that’s left is to setup a cron job to run the script automatically at a predefined interval.
As the same sourceuser use the ‘crontab’ command to create a new cron job.
# crontab -e
This will open an editor where you can schedule the job.
Enter the following to have the script run once every hour
——————————————-
# Run my rsync script once every hour
0 * * * * /path/to/rsync.sh
——————————————-
Your 2 servers should now be syncing the chosen directory once every hour.
Hope this helped, let me know if you have any questions.

How To Install Perl Modules Manually and Using CPAN command


How To Install Perl Modules Manually and Using CPAN command

Perl CPAN LogoInstalling Perl modules required by various open source software is a routine tasks for sysadmins. Installing Perl modules manuallyby resolving all the dependencies is  tedious and annoying process.

Installing Perl modules using CPAN is a better solution, as it resolves all the dependencies automatically. In this article, let us review how to install Perl modules on Linux using both manual and CPAN method.


When a Perl module is not installed, application will display the following error message. In this example, XML::Parser Perl module is missing.
Can't locate XML/parser.pm in @INC (@INC contains:
/usr/lib/perl5/5.10.0/i386-linux-thread-multi
/usr/lib/perl5/5.10.0
/usr/local/lib/perl5/site_perl/5.10.0/i386-linux-thread-multi
/usr/local/lib/perl5/site_perl/5.10.0
/usr/lib/perl5/vendor_perl/5.10.0/i386-linux-thread-multi
/usr/lib/perl5/vendor_perl/5.10.0 /usr/lib/perl5/vendor_perl
/usr/lib/perl5/site_perl/5.10.0 .)

Install Perl Modules Manually

Download Perl module

Go to CPAN Search website and search for the module that you wish to download. In this example, let us search, download and install XML::Parser Perl module. I have downloaded the XML-Parser-2.36.tar.gz to /home/download
# cd /home/download
# gzip -d XML-Parser-2.36.tar.gz
# tar xvf XML-Parser-2.36.tar
# cd XML-Parser-2.36

Build the perl module

# perl Makefile.PL
Checking if your kit is complete...
Looks good
Writing Makefile for XML::Parser::Expat
Writing Makefile for XML::Parser
# make
# make test

Install the perl module

# make install
This is very simple for one module with no dependencies. Typically, Perl modules will be dependent on several other modules. Chasing all these dependencies one-by-one can be very painful and annoying task. I recommend the CPAN method of installation as shown below. Use the manual method only if the server is not connected to the Internet.

Install Perl Modules using CPAN automatically

Verify whether CPAN is already installed

To install Perl modules using CPAN, make sure the cpan command is working. You should have the CPAN perl module installed before you can install any other Perl modules using CPAN. In this example, CPAN module is not installed.
# cpan
-bash: cpan: command not found

# perl -MCPAN -e shell
Can't locate CPAN.pm in @INC (@INC contains:
/usr/lib/perl5/5.10.0/i386-linux-thread-multi
/usr/lib/perl5/5.10.0
/usr/local/lib/perl5/site_perl/5.10.0/i386-linux-thread-multi
/usr/local/lib/perl5/site_perl/5.10.0
/usr/lib/perl5/vendor_perl/5.10.0/i386-linux-thread-multi
/usr/lib/perl5/vendor_perl/5.10.0
/usr/lib/perl5/vendor_perl /usr/lib/perl5/site_perl/5.10.0 .).
BEGIN failed--compilation aborted.

Install the CPAN module using yum

# yum install perl-CPAN

Require SMTP Authentication CpanelX - WHM


Require SMTP Authentication

For WHM version 11.30
By default, WHM uses POP before SMTP authentication. This means that when a user on a POP mail server authenticates a session, he will be allowed to send messages for 30 minutes without re-authenticating through SMTP.
While this method is secure, some administrators prefer to use SMTP authentication at all times. To require SMTP authentication, issue the following command as root in a terminal session:
/usr/local/cpanel/bin/tailwatchd --disable=Cpanel::TailWatch::Antirelayd
note Note: The same applies for IMAP servers. If you're running an IMAP mail server and you wish to require SMTP authentication when messages are sent, you will need to run the command listed above.
