I have few servers and their IP addresses. Ideally password for all servers should be same for a particular user but few servers might have an unknown passwd for that user.
I want to create a script that will log in to each server one by one (which ever is possible) using same username and passwd and take details like hostname etc.
Is that possible?
I searched and looks like expect may do it some part of it.
Any reason not to use SSH? Once you get SSH public-key authorization set up, you can stop worrying about storing passwords in "expect" scripts. (And if you're not worrying about that now, then perhaps you should start.) With SSH public-key authorization, no one even cares what a user's password is.
Dozens of old threads describe how to configure SSH keys.
