Re: [Ssh-sftp-perl-users] Net::SSH::Perl - Problem with cmd()

[Dave R. <au...@ur...>]

Can you do me a favor and report this via rt.cpan.org at
https://rt.cpan.org/NoAuth/ReportBug.html?Queue=net%3A%3Assh%3A%3Aperl
?

More than one person will be working on maintenance for this module, so
having real bug tracking is important.

Thanks,

-dave
