I recently upgraded them from various 4.4 and 4.3 versions to 4.5-RC. Now I have two clients who say their connections to the boxes are stalling, anywhere from a few seconds to several minutes. They can even have one connection stall, yet make a second one that works fine while the first one sits stuck. Today I upgraded one of the machines to 4.5-STABLE, and it made no difference. These clients both use DSL (different providers in different states), and one of them tried a friend's cable modem, and noticed the same problem. It happens with ssh connections and pop3, so it doesn't seem to be a problem with a certain program. I connect to these systems over a modem, and I'm not having any trouble. They also seem to have no trouble talking to each other over the 100Mb LAN. Lots of other people connect to these systems, and we're not getting other complaints, so it seems to be limited to these guys with high-speed access. The machines have Intel Pro 10/100B NICs, so they're using the fxp driver. The only thing I do special on them is to run this command in rc.local: /sbin/ifconfig fxp0 media 100baseTX mediaopt full-duplex That's because if I let them auto-detect, they don't seem to negotiate correctly with the switch, and move data very slowly. Any ideas? The key seems to be the DSL and 4.5, but I can't figure how that is causing the problem.
