http://ubuntuforums.org – Hello, I got a new low power file server (Atom 330 with ion), but didn't enjoy it since. I installed Ubuntu server 9.10 64bit. I randomly experience connection drops. As I'm installing and testing, there are lots of ssh windows open, I transfer much data using scp from my laptop to the server (all connected to wired lan). Connection drops are as follows: ssh windows terminate with "connection reset by peer", but not always all the ssh windows terminate. For example, I edited a mediatomb config using nano, that stayed open even with scp and all other ssh windows cut. I also have apache2 installed because I'm running urd (a usenet download tool). It seems that when I start the deamon, connection drops. So I killed apache2 to try out but that didn't solve the problem. I left ping run all the time, and the server is pinging back all the time, which is really strange as I thought that a connection drop means the whole network interface going down. When this drop occurs, I have to wait 2 minutes until I can ssh back into the server. I also installed mediatomb, but it isn't really fun to stream a video to my ps3 as it always hangs after 5 to 10 minutes. What info do you need? Anyone an idea how to solve this?
