Subject: Module dies if connect fails
This does NOT work: $ssh2->connect( $host ) or die "Connection cannot be established"; because the die never occurs. Reason: Connect method does not return anything, it just dies (because there's a croak call in the code). Croak should be replaced with 'return undef' or something else, which returns something and let's the calling procedure to catch the error.
Catch it with eval.

Yes, it can be cought with eval. However, it would be nice if the example codes which make use of "connect or die" would work as intended. Regards, MarkusV 2009/8/5 David Robins via RT <bug-Net-SSH2@rt.cpan.org>:

In 0.22, this will do what you expect: $ssh->connect(...) or die $!; In void context, it will continue to throw an exception: $ssh->connect(...); # <-- this throws exception -- Rafael
