It seems that your login succeeds. Maybe public key authentication has already been set up and you don't need to log at all. Anyway, post your code. Otherwise is not possible to really know what you are doing wrong. And, BTW, why are you using Net::SSH::Expect? usually it is not the best alternative.	[reply]

Hello salva, What is a better alternative to Net::SSH:Expect? I use it but don't know any better. Thanks, Rob	[reply]

Nowadays, Net::SSH2 or Net::OpenSSH are probably your best options unless you are connecting to one of those routers or switches that only provided a crippled restricted shell or a broken SSH implementation. In that case, Net::Telnet (its docs explain how to use it over SSH) or even just Expect are in my opinion the way to go. Net::SSH::Expect is just not reliable, specially over slow networks, due to the feeble way it uses to detect when remote commands finnish.	[reply]

You are getting in. string log_file Used as argument to the internal Expect->log_file() method. Default is no logfile. I would guess after expect logged in it never got what it was waiting for and just waited till it timed out. I agree... It would be helpful to see the code and a log of what is happening. Good Luck, Rob	[reply]
