Date: Thu, 22 Aug 2002 16:48:53 -0700 (PDT) Folks, I've just gotten a PacBell/SBC DSL account up and running in at home in SF. Getting on the net was surprisingly easy -- good to see that Linux is smoothing out the driver problems. But the problem is staying connected. When I ssh to my work machine, the connection is frequently dropped so that the xterm on my home machine locks up. sshd is still running the server. The main connection appears to remain intact since I can open up another xterm and ssh to the same server as soon as one connection goes dead. The connection seems more likely to die when I stop entering input into the xterm. If I'm actively using the xterm, it rarely dies on me. Usually, 3-5 minutes of inactivity and the connection's dead. So it's as if there are intermittent hiccups which kill the ssh connection. Any ideas?

Try adjusting the MTU of your interface like so: # /sbin/ifconfig eth0 mtu 1400 HTH ===
