Full Discussion: How to disable/bypass passphrase prompt in ssh?
Operating Systems Solaris How to disable/bypass passphrase prompt in ssh? Post 302753423 by chidori on Tuesday 8th of January 2013 03:30:36 PM

Thanks for the explanation.

I have this strange question in mind . As the pages from google say to add ssh-agent and ssh-add commands in user profile so that ssh agent starts each time you login as user and adds the key.

After this it would be in a prompt which would waiting for passphrase input to be given by user. Can automate this particular step using expect tool ?

I know its security risk but just being curious to know if it can be done via expect / any other tool
