Scratch that, I think the packet loss is caused by something else. I'm only getting it on one of my computers, and it works no better without the patch. My setup is as follows: helen --- LPIP --- niobe --- Ether --- luna | PPP | Internet Needless to say, Niobe is set up as a gateway. Both Niobe and Luna have 3Com 3c509 NICs. Ssh from Helen or Niobe to Luna doesn't work reliably; 'ssh -v luna' stops with "Waiting for server public key"; once in a while, it gets all the way to "requesting shell" and hangs there. If I reboot Luna, it will work for some time after the reboot (5-10 minutes) then gradually stop working. Ssh between Luna and Niobe works just fine, 'ping -f luna' from Helen shows no packet loss. Luna is headless, so I can't experiment much with ssh from Luna to Niobe or Helen, but yesterday, when I had a monitor plugged in on Luna, I noticed NFS and NIS were very flaky; not entirely gone, but flaky. All three computers run -current, and all three had their world remade yesterday. The problem manifested itself with the first kernel I compiled with your patch, but since I cvsupped right before I applied that patch, it may have been caused by something else. I have had absolutely no network problems between Luna and Niobe (except for forgetting to ifconfig lo0 on Luna) since I installed Luna on saturday - in fact, I did a minimal installation from the February snapshot CD-ROM, then cvsupped the entire tree from Niobe and made world. Niobe and Luna have IP addresses 10.0.1.1 and 10.0.1.2 respectively; on the LPIP link, Niobe and Helen have IP addresses 10.0.2.1 and 10.0.2.3 respectively. Niobe also has an (unused) Accton 2107 with IP address 10.0.3.1. Netmask is 0xffffff00 on all interfaces. Niobe is NFS, NIS, CVSup, FTP and HTTP server, and HTTP proxy. Luna is NFS and NIS client. Helen, being a laptop, does not use NIS, but mounts the repository over NFS from Niobe (not that I ever use it on Helen). DES -- One two, one two, one two.
