With kernel 2.6.17.13 or higher, you can limit the scaling factor for that broken host with: THEIR_IP=1.2.3.4 MY_GATEWAY=5.6.7.8 ip route add $THEIR_IP/32 via $MY_GATEWAY window 65535 which limits window scaling for that destination without interfering with your other connections. --Pete - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

server don't accept ip-connections from linux
hello, i have a big problem: some servers send a rst-packet or don't answer if i want to open a connection with them. this happens with the web-server with ip 15.200.6.123 and my smc- barricade router/printserver. if i make a connection from windows or linux with kernel 2.2, it works, with kernel 2.4, i get a rst or no answer and the connection is closed. i don't know, what is the difference of the tcp-packets from windows/kernel 2.2 and linux with kernel 2.4. but with kernel 2.4 i have trouble with some servers. i check the packets with an analyser and make some test. if i disable ecn with "echo 0x0 > /proc/sys/net/ipv4/tcp_ecn" it works, with ecn enabled, it don't work. goodby Schau auch einmal auf meine Homepage (http://go.to/dieter-ferdinand).
