Net::SSH::Perl relies on a number of modules for the different cipher types, DES as
well. The local SSH client has nothing to do with the module as it handles the whole
process internally rather than shelling out or using an external client. If it is
telling you all you have available is RC4 then that is probably correct and you need
to install the other modules.
If my records are correct you should only need Crypt::DES to add DES support. You
might try installing using CPAN rather than the SUSE package (if that is how you
installed it) so that you are prompted for the compatibilities you want in
Net::SSH::Perl and to make sure the dependencies are satisfied as there are a lot of
them (if you installed from CPAN did it not prompt you?). I will attach the dependency
chart I generated before (though it may not be complete, for all ciphers, etc.)
(There is also a bug in Math::PARI/pari if you have a long running application that
causes a memory leak that generates weird results - it takes about 2 hours to generate
running about 30 commands every minute)
Does this help?
