[Bug 174168] Re: expecting SSH2_MSG_KEX_DH_GEX_GROUP

[Tessa Lau]

I have the same problem ssh'ing from a 11.04 box (running openssh 5.8)
to a 10.04 box (running openssh 5.3).  I've tried with three different
clients all on the same network, two of with have 11.04 and one of which
has 10.04. All are connecting to the same server Only the 10.04 box is
able to connect. I believe the MTU's are the same on all the boxes.

This seems like an incompatibility between different versions of
OpenSSH.
