(And very difficult to implement from the server > side I'd think.) Hm. I think I may have been rather unclear with my description. I have my firewall configured to allow *all* outgoing connections, and to deny all incoming connections (with the exception of a couple of totally non-standard high-up ports that I'm using for file-sharing clients) So... I'm assuming that when I initially connect to the server, I'm initiating an outgoing connection, and just keeping the port open indefinitely. Which is why I can receive incoming messages... yes? Now, my hypothesis (based on *very little* understanding) is that Trillian reaches an agreement with the server that 'so-and-so is online' packets will come down the same line, same (already-open) port... so they slip by the firewall. Maybe GnomeICU doesn't tell the server that that's what I want, so the server sends those messages to some *other* port, and the firewall drops 'em cause they show up as an incoming connection. > What I'm therefore guessing is going on, is something on your desktop > machine.

Other programs are working fine, network performance is beautiful. Somebody mentioned fsck, too (due to the scary and bizarre way that Alicq imploded)... but the partition in question gets fsck'ed every time I boot, and keeps coming up OK. Also there have been *no* other strange behaviours from any other programs that would seem to indicate disk trouble or system problems. Given that, I'm still inclined to believe that it's some combination of client (or client configuration) and NAT/firewall setup that's responsible. > Just to test gaim's networking code, you may want to download > gaim for win32 and try it under XP and see if it works. > (http://gaim.sourceforge.net) That might be a good place to start to > rule out the possibility of a client-based problem. Good luck. Probably not a bad idea... Even though I get this kind of dirty feeling whenever I boot into Windows, these days... Still, I might try that. Thanks for the input Keep it comin' -Chris
