Putty remember username

It does look like you can't specify a username in the putty GUI. However, you do not need to use putty if what you want to do is connect to other linux hosts over ssh. Just open a terminal and type:

ssh user@host

This will do exactly what putty does for you in windows.

If you want putty in order to save connections, add lines like the following into your ~/.bashrc file (the following are adapted from mine):

alias myserver='ssh myuser@myserver'
alias petitbonum='ssh bob@petitbonum' 
alias docpad='ssh terdon@docpad.local'
alias badabing='ssh -Y lacoloc@1.2.3.4'

Obviously, change the user and server names and/or IPs to whatever you need. Then, you open a new terminal and type, for example, myserver and hit enter. This will run the command defined in the alias you placed in .bashrc.

The first thing you need is a key that PuTTY can understand. PuTTY requires a .ppk file, which is not the same as the standard openSSH key file. You can use the PuTTYgen tool to generate a key or to convert an existing openSSH to a putty key.

Once you have a key, you need to tell PuTTY about it. For this you have two options:

• Specifiy a key directly
• Use Pageant to store keys

Once you have PuTTY all setup, you need to make sure you have added your public key to the authorized_keys file. Once that is all setup you should be able to connect.
