Subject: SSH Protocol 2 not working
Download (untitled) / with headers
text/plain 1.9k
I am able to use Net::SSH::Perl v1.30 to connect to hosts that allow SSH protocol 1. However we have hardened many of our servers so they only accept protocol 2, not 1, since 1 is really not that secure. (we are using CentOS 3 and 4 primarily, free clone of RedHat Enterprise) My test script does not specify what protocols to use so "1,2" should be the default (actually I did try specifying "2" or "2,1" but it didn't help so I went back to using the defaults)... On any server that is only accepting protocol 2, I get this error: Connection closed by remote host. at /usr/lib/perl5/site_perl/5.8.5/Net/SSH/Perl/Kex/DH1.pm line 41 I have all of the pre-req modules installed including Math::GMP as well as IO::Handle, as was previously suggested in bug report #14341... I have not had much luck with Net::SSH2 yet (definitely need to go with username/password authentication here, not keys) but I'm still messing with it as well. If I use the example cmd.pl that comes with Net::SSH::Perl here's a bit more output: jeremydev: Reading configuration data /root/.ssh/config jeremydev: Reading configuration data /etc/ssh_config jeremydev: Allocated local port 1023. jeremydev: Connecting to 10.6.6.166, port 22. jeremydev: Remote version string: SSH-2.0-OpenSSH_3.6.1p2 jeremydev: Remote protocol version 2.0, remote software version OpenSSH_3.6.1p2 jeremydev: Net::SSH::Perl Version 1.30, protocol version 2.0. jeremydev: No compat match: OpenSSH_3.6.1p2. jeremydev: Connection established.

Connection closed by remote host. at /usr/lib/perl5/site_perl/5.8.5/Net/SSH/Perl/Kex/DH1.pm line 41 Thanks, Jeremy
Can you please give this another try with the latest version? (1.33 as of this writing)

Hi! v1.34, 1.35 work well with SSH2. Please reopen if issue persists. Steffen -- Steffen Schwigon <ss5@renormalist.net> Dresden Perl Mongers <http://dresden-pm.org/>
