The problem is that Crypt::IDEA has not been updated to handle Perl 5.6's namespace changes. An error message looking like that is a dead giveaway. You didn't mention the version of Perl that you're running, but I'll eat my left hat if it's not 5.6+, and I'll eat my right hat if btrott isn't working with 5.005_03 or lower.

Solution: run perl Makefile.PL POLLUTE=1, and then re-run make.

ObNet::SSH - I got it compiled without much trouble, but ran into three separate errors on trying to connect to the three hosts on which I have ssh access:

[~/src/Net-SSH-0.01] $ perl -Iblib/lib -mNet::SSH
$s=Net::SSH::->new("host1");
$s->login("xxxxx","xxxxx");
print $s->cmd("ls");

I looked around the code a bit, and it looks quite impressive. I'm looking forward to being able to play with it more. Keep up the good work!

Yep. Thanks for clearing this up!

W/r/t the Net::SSH errors:

    Corrupted check bytes on input at blib/lib/Net/SSH.pm line 135

This one bothers me slightly. Though you didn't get the same problem for the other hosts, which is good. Could be a problem w/ the encryption cipher perhaps; that's when I'd get this sort of message during testing.

    Didn't expect to get packet of type 15

15 is a failure message from the server. This is partly due to my not-so-robust error checking at this point. This error message occurs during the client loop after executing the command remotely; only certain packets are expected. Failure isn't an option, ha ha. :)

Anyway, I'll look at this; don't know why trying to run a command would cause failure.

    Can't open /etc/ssh_known_hosts

This is fairly self-explanatory; host3 must not be in your ~/.ssh/known_hosts (or the host keys didn't match--not yet distinguishing this from new hosts), so Net::SSH tried to look in /etc/ssh_known_hosts... which doesn't exist.

Anyway, thanks very much for the error reports. When trying to fix the errors I may now get in contact with you and ask you to rerun them after I implement some better debugging tools.
