For quite sometime now, I was having this issue, that for the home system, I was able to connect to is using ssh but it never worked. Fnally after quite some debugging finally I found that the issue was with thebashrc. So, everytime I had to do a scp I would have to move/rename bashrc and do the reverse action after the scp was done.
Continue readingI like PuTTY quite a bit but do not like the fact that it does not have any tab feature. So, if I am working on multiple machines then un-necessarily I will have too many windows open cluttering my desktop. So, here is the result of my quest to find the alternative:

you can do a ssh without password.. Today we will see how to do this with putty.
Generate public/private (DSA)key pair using puttygen.
copy the public key to ~/.ssh/authourized_keys on your server (moonware/sunware/skyware). Same key can be used on all the servers.
make sure that your home directory permissions are 755
directory permission for .ssh is 700
file permission for authourized_keys is 600
now login using putty and specify your private key in the configuration of putty and also specify your username.
Sometimes after hours of searching you find a link so good that it needs no introductions and neither any writeup. I found one such page today :

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.
Setting the title for PuTTY window is quite a simple trick. The trick is to set the PS1 with a escape sequence. When the PS1 is set with the escape sequence the variable will set the title window also. And not only can this trick be used in PuTTY but even on gnome-terminal to set the title dynamically. You can use this in the .bashrc or .bash_profile file to do it whenever you are starting the terminal.
