Message-ID: <20010702110533.A45523@nm.ruhr-uni-bochum.de> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.2.5i Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG 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?
