Hello "Hackers", i think the tcp code in 4.3-RELEASE (and at least stable from last week) has a serious bug in tcp handling: I use "LPRng 3.6.20" and openssh on the 4.3 box, lpd-server is on a 4.1 box. Issuing 4-5 lpq's in a minute gives "Connection timed out". First i thought it may be a problem with LPRng, but scp'ing large files doesnt work anymore, too. Even ssh hangs sometimes. I tried to disable the "newreno" stuff with sysctl, didnt change anything. Why i suspect a tcp problem? The host scp connects to shows: "LAST_ACK" in state (netstat), The host initiating the scp connection shows "ESTABLISHED" in state. I hope its no problem on my side, but i checked the archive before and I did not have this behaviour on 4.2 Any ideas?
