Methods to SSH (Perl)...
Can anyone break down the different methods of using SSH in perl? I'm currently using Net::SSH::Expect, which allows me to login to a machine and execute multiple commands without having to ssh again. This feature of holding the session works well for me, but it's slow. If I set timeouts to 4 seconds, I have to wait the full 4 seconds on each command I execute. the timeouts can be changed on the fly, but that still isn't the best plan for my script. Does anyone know of a method that allows these sessions and will continue the script immediately after a command is executed? The waiting part is an issue for me and sometime, I need to set a really long timeout. If I'm not explaining this well enough, I can elaborate:

If I set timeouts = 10, it'll take 10 seconds to login, 10 seconds to run $ssh->exec("cd somedirectory"); and 10 seconds for each subsequent exec.

If my changing of a directory can finish in less than a second, I want it to begin the next line of code immediately. Can anyone help me out?

Thanks in advance for all responses.

Also, are there any books that break down the advantages/disadvantages of other functions/classes/etc. ? I'd like to see something with code usage as well.
