Hi,

I am using the Net::SSH::Perl Module under RedHat Linux and try to establish a connection to a remote host via SSH.

Whatever SSH version I take or whatever Crypt I use I always get error messages.
When activating the debug I get e.g.:
localhost.localdomain: Reading configuration data /root/.ssh/config
localhost.localdomain: Reading configuration data /etc/ssh_config
localhost.localdomain: Allocated local port 1023.
localhost.localdomain: Connecting to localhost, port 22.
localhost.localdomain: Remote protocol version 1.99, remote software version OpenSSH_3.5p1
localhost.localdomain: Net::SSH::Perl Version 1.23, protocol version 1.5.
localhost.localdomain: No compat match: OpenSSH_3.5p1.
localhost.localdomain: Connection established.
SSH connection established. User logged in.
localhost.localdomain: Waiting for server public key.
localhost.localdomain: Received server public key (768 bits) and host key (1024 bits).
localhost.localdomain: Host 'localhost' is known and matches the host key.
Selected cipher type 3des not supported by server. at performanz.pl line 290


or if I take the version SSH-2 and 3des-cbc I get:

localhost.localdomain: Reading configuration data /root/.ssh/config
localhost.localdomain: Reading configuration data /etc/ssh_config
localhost.localdomain: Allocated local port 1023.

input must be 8 bytes long at /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi/Crypt/DES.pm line 57.

It looks to me like I have an Problem with encryption mechanism. I installed all the packages from CPAN that are needed. The changing of the SSH Version or the encryption method, interactive or non interactive setups do not change anything on the problem...

Any idea ?

THX for your help.
