What is ippp0? shouldn't that be ppp0 for you? What part of the chain are the rules in? If they are "appended" to the bottom and a rule above matches they'll never get hit. Try -I input to "Insert" them into the top. They should match then. --mike On 08 Aug 2001 10:18:37 +0200, [EMAIL PROTEC

In /etc/sysklogd.conf or something like that you can route all that traffic to a tty, e.g. tty6. I did it that way and now all other tty's keep quiet. I'm sorry, because now I'm not at my server (down in the cellar) to have a look at the files and Windoze dosen't have ssh. Michael -- Michael Stei
