The best putty package available

Bored of Black screened Task bar filling putty? Issues with porting Saved sessions from machine to machine? Do you like tabbed SSH sessions? Start using portaputty instead of normal putty and link it with puttycm . Puttycm supports sessions to be saved in its own Database files. You can use the Putty sessions you have saved already right inside putty. You can have any number of databases which allow you to arrange Remote servers in folders and convenient namings. I personally recommend creating Database with puttycm rather than using the sessions saved in putty which doesn't offer any option to create folders and saving sessions under that directory tree. You can even save username/password to get it logged automatically and there is an option to pass commands to be run soon after login. I can't recommend this since some bug was found with these options. Portaputty is a variant of putty which stores all the Configuration data in text files instead of MS Window

screen for Remote assistance and chat

screen is a UNIX utility for giving remote assistance/administration. Suppose an unskilled colleague of your own is struggling with a server at some remote location with no idea of troubleshooting a problem. If you are able to solve that with keeping your colleague to watch how you are sorting out the issues you can use screen . First of all ask your colleague for the username which he used to login into that remote machine. Now you can login to that remote machine as the same user. Imagine username is engineer and IP of the remote machine is 192.168.1.1. Try the below # ssh engineer@192.168.1.1 Then after getting logged in run the screen command to set a session named myscreen $ screen -S myscreen Now tell your colleague to type the below for attaching his screen to your screen. $ screen -x myscreen Thats it. Now he can watch whatever you type and vice versa.

Run X11 programs after SSH and switch to another user

This issue arises when you are logging in as root and trying to launch some X11 programs after doing a switch to user oracle. One solution is to login directly as the user as which you want to run thos X11 programs. One more workaround is there.Here you can login as a different user. Thereafter run the below command xauth list | grep "`hostname`/"| grep `echo $DISPLAY | cut -f2 -d: | cut -f1 -d.` Copy the output. Then switch to second user and run xauth add as this output as an argument as below xauth add training/unix:13 MIT-MAGIC-COOKIE-1 57f03bee06be924299b0bedde6499bd1 Now run any X11 programs.
