Guys, You can say all you like, but something in stable is totally fscked up. As soon as I log in and start doing anything that involves a bit of traffic (e.g. tailing a file), the connection freezes and I have to kill it. sshd doesn't die, so I can log in again. I can reproducibly freeze it by doing... well practically anything: tail /var/log/messages, vi, cat, etc. all freeze the connection. Strangely enough, head /var/log/messages works fine. At first I thought there was something wrong with the hardware, and that perhaps the disks were screwed, that the recent filesystem changes caused it, that pipe() was broken, lots of other things. But everything points to ssh. "slogin -1" seems to work a bit longer, but also eventually freezes. Note that BPF is compiled in, so maybe there is some weird interaction between ssh and bpf (as Colin Legendre suggested). I also thought it was a networking problem, but this machine is colocated next to a Sun E450 with a similar setup (same subnet), which works fine. The client ssh I tried were all 2.9p2 (Solaris) and I think 2.9.9p2 (Solaris). I also tried to log in from other FreeBSD machines (4.2 and 4.3), but the effect was the same. $ make world > makeworld.log & generated a 6Mb file as expected. However, I could neither head nor tail it. Interesting is that Putty (Windows SSH client) doesn't seem to have this problem. I used it for quite a while and it didn't freeze. Please help me figure out what's going on. I don't have physical access to the box, and without the ability to view or edit files there's very little I can do. scp from a remote machine freezes. scp to a remote machine freezes. There's no telnet or ftp. How can I even diagnose the problem? I am running out of ideas... :( John Wilson _______________________________________________________ Send a cool gift with your E-Card http://www.bluemountain.com/giftcenter/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
