Re: [JSch-users] Shell.java not working

[campo <rob...@gm...>]

Thank you both for your help. The problem was with 'System.in' I am now able
to log in and enter commands. I can use:

*channel.setInputStream(System.in);*

now as long as I use an input file, i.e.:

java Shell < unix.script

which is exactly what I need.
