Now I did ;) And horribly I had to see, that traceroute seems to transport even larger packets an get's the wanted answers. I also tried after that shock >traceroute -P TCP< and seen, that it works, too. But an >echo "GET / " | telnet www.uni-halle.de 80< didn't get any answer (keeps empty). Using links or firefox to query a web-site results in keeping the browser querying and I cannot see any sent response in the tcpdump. I don't have a firewall in the kernel nor loaded as module etc. (A friend I asked yesterday, asked that back at the first). Beste regards, Jens
