Key Based Authorization with SSH

Submitted by abhishek on Wed, 08/26/2009 - 19:09

Using remote shells is all time favourite but remembering those many passwords is a pain so here are the steps to login using SSH without putting a password :)


1. Create a public ssh key, if you haven’t one already. Look at ~/.ssh. If you see a file named then you obviously already have a public key. If not, simply create one.

ssh-keygen -t dsa should do the trick. Please note that there are other types of keys, e.g. RSA instead of DSA.

2. Make sure your .ssh dir is not publically writable

    # chmod 700 ~/.ssh
