CHECK PERL MODULE LINUX CENTOS

[root@spam ~]# perldoc -m Mail::Send

specify a minimum module version

( categories: perl modules )

Sometimes you must use a specific module version in your programs. To avod using earlier version of that module, append the minimum version number you want in the use 'module' statement:

Example:

#-- Use version 5.8 of later of module LWP
use LWP 5.8

Your program will exit with an appropriate error message if the installed module version is lower than the version you specified

execute commands on remote machines using ssh

You can execute commands on remote machines from a Perl script using the Net::SSH::Perl module.

This module allows you to execute a command remotely and receive the STDOUT, STDERR, and exit status of that remote command.

One big advantage of Net::SSH::Perl over other methods is that you can automate the login process, that way you can write fully automated perl scripts, no console interaction is required in order to authenticate in the remote machine.

Example:

list the installed modules

( categories: installing modules | perl modules )

There are several ways to obtain the list of perl modules installed in a system:

Linux and Windows FireFox issues : Error code: sec_error_reused_issuer_and_serial

It took me a while to figure it out from googling, but the solution is simply to delete the cert8.db from your FireFox profile, usually found in /home/hafiz/.mozilla/firefox/t5q6cggf(some-name).default and Easier still just search for cert8.db in your computer and delete that file. Close and Start again your firefox

Windows:

It took me a while to figure it out from googling, but the solution is simply to delete the cert8.db from your FireFox profile, usually found in C:\Documents and Settings\<yourname>\Application Data\Mozilla\Firefox\Profiles\<yourprofile>. Easier still just search for cert8.db in your computer and delete that file.

Oh….. you need close FireFox first

Got this information somewhere in net and worked fine for me.
