Need Help??

davidsnt has asked for the wisdom of the Perl Monks concerning the following question:

I need to write a application that can log in to a serevr farm and change as different user (sudo su -l user2) and execute a couple of commands and print the results. I dont want to use Expect module to supply the passwords and I dont have the infrastructure to have the ssh fingerprint copied to all the servers in the farm. Is there a possibility to use the default ssh -t option with Net::SSH::Perl module

Is there a possibility to use the default ssh -t option with Net::SSH::Perl module Offhand, I'd say yes. Did you try?	[reply]

`ssh -t` makes sure that sudo can prompt for a password. Copying ssh fingerprints (or public keys) avoids the password prompt by ssh. These are two different things.	[reply] [d/l]

Check Net::OpenSSH and Net::SSH::Parallel. Both can be used to run commands through sudo easily. Net::SSH::Mechanize also claims to support sudo natively.	[reply]
