in reply to Corruption between Net::SSH::Perl and Net::Telnet

From the cpan POD info on Net::Telnet:
If you have the IO:: libraries installed (they come standard with perl5.004 and later) then IO::Socket::INET is used as a base class, otherwise FileHandle is used.
Net::Ftp only uses the IO libraries. It seems like the IO libraries are there (or Net::Ftp would complain), but that's where I'd begin looking. Try explicitly using IO::Socket::INET at the top.
