sit0 is an odd new interface, it is meant to (i think) allow ipv6 traffic (the new internet standard) to be carried over ipv4. you basically won't ever see it used unless you are at an american university on Internet2. iptables and ipchains live in /usr/sbin, you can run them as a non-root user if you type in /usr/sbin/ipchains, but none of the commands will work other than -h, /usr/sbin> ./iptables -L iptables v1.2.5: can't initialize iptables table `filter': Permission denied (you must be root) Ewan On Sun, 2002-08-04 at 23:03, W.W.

Thanks Ewan,
i ran ifconfig, but what is sit0? I'm curious / trying to learn.
sit0 Link encap:IPv6-in-IPv4 NOARP MTU:1480 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:0 (0.0 b)
Also is the reason why the iptables and ifconfig aren't runnable as a normal user because of the $PATH, or is it permissions? Not that I would change them. When I checked out root's $PATH compared to mine, I'm guessing there in /usr/sbin or /sbin. I'm probably mistaken though.
To my suprise i do connect with ppp0.I should have su'd before, but I try not to play as root.My unix teacher would be so upset we just learned ifconfig a few weeks ago.
The only thing of importance in my /etc/sysconfig/personal-firewall is
reject_all_incoming_connections="no",
which seems wrong shouldn't it be yes? I don't need any holes open, and couldn't I add to hosts.allow if I did?
But then again I'll probably just use firewall2, since it is ppp0.
Where is the best place for me to get information about linux, and suse? Is learning by doing better than learning by reading?

iptables is only runnable as root user, if you do want to see what it runs you'll need to type "su -" in a console then enter your root password.
you'll be given a ppp0 interface when you are finished logging in to your isp. you can see it by running (as root again) "ifconfig -a" to see all your network connections (lo0 is your local loopback connection).
i suspect the personal firewall problem is to do with a misconfiguration somewhere, probably a missing character in /etc/sysconfig/personal-firewall or similar
