I'm trying to build a case now that there is something strange going on 
with static IP addresses in Ubuntu. I posted something a few days ago 
"ssh Connection reset by peer problems " where I've been experiencing 
unreliable network connections that show up in ssh. Of course I got no 
response to that post. I though I had traced the unreliability down to 
difference in the install on two Dell platforms, but now it is pointing 
to the difference is between using DHCP or static address.

I had the system up all weekend on a couple connections (with a DHCP 
address), one of them running a script (AppleScript terminal script) 
that did a date command every minute. Those connections stayed up all 
weekend.

This morning, figuring I had a band-aid, I did two actions. I did a 
Ubuntu Update manager, and changed the network address to a static IP 
address. I did a little minor checking between the two and did not see 
a problem with the update. After changing the network to static and 
running my script, the connection will be reset after about 20 minutes. 
I tried it twice with the same results. Changed back to DHCP and it's 
been going for over an hour.

My post points to some other details in previous posts, but when I 
first tryed to find the problem I would get things like "Socket 
somthing" failed. Then it would refuse connection of port 22 (ssh) for 
about 2 minutes, and then it would connect.

Again, something strange going on and I've wasted a few hours a day for 
about two week and the Ubuntu list and other resources I've tried 
(bugzilla) don't seem to be of much help.
