PuTTY export client display on login for opening X application and terminal.

2010-04-11 1 min read Bash Linux

export DISPLAY=$(echo $SSH_CLIENT |awk '{print $1”:0.0”}’)

Explanation:

SSH_CLIENT contains the IP and the port of the client machine. So we need to export (Client IP):0.0 for the display on the client machine. If the above is put in .bashrc or .bash_profile or .profile, then the DISPLAY variable will be set based on the client machine.

while ($line = )
{

if ($line =~ /(Received :)|(Sending :)/)

{

@words = split(/\|/, $words[4]);
$received = $words[1];

Today I was trying to do some queries and see if I could create a new bug or update a existing bug in the Bugzilla. The one that I was trying to access was on version 2.0 and not on 3.0. This being the case, the XMLRPC interface was not working properly and to top it all, I was wanted to query quite a lot of bugs. So, I went out to evaluate how to avoid the manual work and get this done faster. Here’s some of my findings:
