Re: ssh problem
Just a thought
I had a similar issue in the past.
I connect to several servers over ssh from my ubuntu 8.10 machine.
Servers were debian 4, opensuse and ubuntu 8.04. The ssh connection
would freeze if I issued a long ls command "ls -l /etc" for example.
cat a big text file. Editing with vi was an almost sure freeze. Guess
what. I tried windows and putty to connect and no freezes. So I think
"ssh client problem?" I try messing with lots of ssh_config options
and no success, I try to run putty over wine and FREEZE! I found no
solution but to reboot to windows and use putty. Eventually it stopped
freezing without a reason. I now use ubuntu 9.04 as desktop but it
stopped freezing while still using ubuntu 8.10. I really don't know
what was happening that time.

The logic would be that smaller packets have higher chances of getting through, both on initial send event and when re-sending non-ACKed packets. I could be totally wrong here, so that is why I'm asking.
> I had recently deteriorating link quality to my server, which manifested itself as rising (on the scale of dozens of hours) percentage of lost packets when running mtr or ping from my server to some external server. This had finally led to complete loss of connectivity. I did get higher link reliability by decreasing link speed to 10MBps, I haven't tried MTU though. Link was fixed by tech support doing something either to the patch-panel or a patch-cord between the server and patch-panel.
