Strangely > enough, I've seen this before, or something that sounds identical. telnet did the same thing, and anything over a size i dont remember via http did it as well. The workaround I found was to drop the MTU on the ethernet card (a generic ne2k card at the time, no idea what it was plugged into.) down to 512 and it was fine. Move it above 512 and the problems came back. This was with 3.0 and 3.3 release...that machine was only recently pulled out of service. sshd version 1.2.27 [i386-unknown-freebsd3.0], stock telnet, and i'm not sure what apache. (happened to /all/ available clients that i could find..) If i only issued "short" output commands, 1/2 to 1 page (80x24) long, the problem didnt seem to crop up. after that, it would hang. I DID discover that it was still accepting my input....I could do a "w" from another session, and see the "more" that was running on the other tty. hit "q" on the hung session, and i'd drop back to the shell. I could even logout. anyway. ...david --- david raistrick (deep in the south georgia woods) drais@atlasta.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
