[OpenIndiana-discuss] SSH hangs between two OI systems

[CJ Keist]

Thanks!! Update to this issue: It's not just ssh but any network 
protocol doesn't work!  They two systems can only ping each other, ssh 
and NFS do not work.  I did move the A system to another switch and now 
that I think about it, when they two system were on the same switch, 
that switch is configured with jumbo frame support. I don't think the 
switch I moved system A to has that enabled.  So the MTU just might be 
the issue.
