ssh hangs on SSH2_MSG_KEX_DH_GEX_GROUP



Hi Everybody,

Version info

Machine A Slackware 10.1 / Kernel 2.4.34 / OpenSSH_4.6p1, OpenSSL
0.9.8d 28 Sep 2006
Machine B Solaris 10 Generic_118833-17 / Sun_SSH_1.1, SSH protocols
1.5/2.0, OpenSSL 0x0090704f
Machine C Slackware 10.1 / Kernel 2.6.13 / OpenSSH_4.0p1, OpenSSL
0.9.7e 25 Oct 2004

Remote system sshd version is SSH-2.0-OpenSSH_4.5

When I try to connect from any of the three machines listed above ssh
hangs on SSH2_MSG_KEX_DH_GEX_GROUP.

I did read the article which suggest lowering the mtu values
(http://www.snailbook.com/faq/mtu-mismatch.auto.html)

This did not work. Does anyone know what could be causing this or how
to fix? I have upgraded SSH on machine 1 with no luck. I have also
tried to regenerate the dh keys with the following commands,

ssh-keygen -G moduli-2048.candidates -b 2048

This did not work either. The funny thing is that i have three other
machines on my network who can connect just fine to this remote host.
The machines which do not have problems connecting are running the
following ssh versions,

Machine D Sun_SSH_1.1, SSH protocols 1.5/2.0, OpenSSL 0x0090700f /
SunOS wookie 5.9 Generic_118558-34
Machine E Windows XP / OpenSSH_4.3p2, OpenSSL 0.9.8b 04 May 2006
Machine F Windows XP / OpenSSH_4.3p2, OpenSSL 0.9.8b 04 May 2006


TIA!
