Hi People! I had a cable-modem installed yesterday, and now I'm looking for some good and easy tool to put up a firewall on my linux-laptop. Before I used ppp by modem, and I only had the ports for xwindow, ssh and cups open, but now I get the following from nmap: memphis:/home/kohli/downloads/rpms # nmap -sS localhost Starting nmap V. 2.53 by fyodor@insecure.org ( www.insecure.org/nmap/ ) Interesting ports on localhost (127.0.0.1): (The 1511 ports scanned but not shown below are in state: closed) Port State Service 21/tcp open ftp 22/tcp open ssh 23/tcp open telnet 37/tcp open time 79/tcp open finger 80/tcp open http 110/tcp open pop-3 513/tcp open login 514/tcp open shell 631/tcp open unknown 901/tcp open samba-swat 6000/tcp open X11 Nmap run completed -- 1 IP address (1 host up) scanned in 1 second Why is that? I already reran harden_suse3.2, started a firewall with firestarter... nothing changes... could anybody help me? tia markus __________________________________________________________________________ The dark ages were caused by the Y1K problem.

# nmap -sS localhost ^^^^^^^^^
Are you sure you secured your box aginst local attackers? Usually localhost isn't protected very well, since a local user has often better changes with buffer overflows and others. Try to nmap your host from a different, _external_ machine or at least nmap your external IP. oki, Steffen -- Dieses Schreiben wurde maschinell erstellt, es trägt daher weder Unterschrift noch Siegel.
