I've got a four computer LAN at home. One computer is the OpenBSD 3.8 box, which is the firewall/router/gateway.
I haven't made any changes to this box in months. Just today, however, I noticed huge latencies when I try to ssh to another computer on the LAN. Previously, I was connect an instant after pressing return. Now it takes several seconds before the connection is made. Likewise, even ping'ing other machines on the LAN takes 5--10 seconds before I see any response. When the replies do start coming back, they are on the order of fractions of milliseconds. I don't believe that this is a hardware problem, as the other machines can "talk" to each other without any noticeable latency. The OpenBSD box is otherwise unloaded. Also, I did a "route show" and it took about two minutes before the whole routing table was shown---each entry had a few seconds of delay before it was shown. Finally, I have a squid proxy running on another machine in my LAN. I use an SSH tunnel to connect to this proxy via the OBSD box. However, in the current state, the latency is too high to use this proxy server. Furthermore, any attempt at using the proxy in this manner causes the ssh session to appear "locked up" (i.e. frozen). Does anyone have any thoughts on why I suddenly have crazy latencies like this? How can I got about further diagnosing the problem? Thank you! Matt
