Date: Thu, 26 Jul 2012 17:56:30 -0700 (PDT)
To: bug-Net-SSH-Perl [...] rt.cpan.org
From: Andrew Daviel <advax [...] triumf.ca>
If I use Net::SSH::Perl to connect to an ssh server on CENTOS5, or on a Juniper appliance, and use SSH 2 with compression enabled (which is the default in Juniper's Perl API), I get a negotiation failure in kex for zlib comprssion example: use Net::SSH::Perl ; my %param ; $param{debug} = 1 ; $param{compression} = 1 ; $param{protocol} = '2' ; my $ssh = Net::SSH::Perl->new("example.com",%param); $ssh->login("foo", "bar"); ($out, $err, $exit) = $ssh->cmd("uptime"); print "$out" ; client: Connecting to example.com, port 22. client: Remote protocol version 1.99, remote software version OpenSSH_4.4 client: Net::SSH::Perl Version 1.34, protocol version 2.0. client: No compat match: OpenSSH_4.4. client: Connection established. client: Sent key-exchange init (KEXINIT), wait response. No matching comp found: client zlib server none,zlib@openssh.com at /usr/lib/perl5/vendor_perl/5.8.8/Net/SSH/Perl/SSH2.pm line 92 regards -- Andrew Daviel, TRIUMF, Canada Tel. +1 (604) 222-7376 (Pacific Time) Network Security Manager
