Default Q: firewall configuration in SUSE Linux 10.1

Hi,

I recently installed Suse Linux 10.1 in a dual boot configuration (with
Windows XP) on my laptop. Everything seems to work fine except that I don't
have access to the Internet. I think it's the firewall that I have to
configure, but being new to Linux I have to rely on Yast to do this.
Unfortunately it does not come with a manual of its own. Is there some
documentation or book out there on how to do this ?

(I have an external DSL modem connected to the ethernet card in my laptop,
this much I know. The Wizard took care of the configuration under Windows)

Thx
Bernard

It's unlikely the firewall's responsible if you can't access anything on the
internet. SuSE's firewall only blocks incoming ports by default but if you
want to find out if it IS getting in the way, try this...

rcSuSEfirewall2 stop
(Well, I assume it's still that command, it might've changed in recent
releases)

Did you have the network card set to be configured by DHCP?
What is the output of ifconfig?
Can you do any nameserver lookups? try "host slashdot.org", see if you get a
reply. Try a "traceroute slashdot.org" if you can, or
"traceroute 66.35.250.150" if not, see if you can actually get out onto the
internet at all.

The hardware seems to work, at least I got a confirmation after
disconnecting and reconnecting the Ethernet link. Should I check something
else as well ?

I got the message command not found using different variations, but see
below.

I also got a command not found on ifconfig, although it is described in the
man pages, so I guess more things are missing in this installation.

On the host command I got a connection timed out; no servers could be
reached. The traceroute returned another command not found.

Ahhhhh, Different paths for different users. You need to be logged in as
root to turn off the firewall or as a user type /sbin/ifconfig to access
that command (because users don't get /sbin in their path, it's considered
an administration command for root)

reet, so no internet routing currently.
As root, go into yast, network devices, network card and make sure it's
setup correctly to use DHCP (that should then automatically configure itself
based on info presented by the ISP). Don't set a static IP address. That
might be the problem.

Modem or Router ?. It does make a difference, especially if this is a DHCP
issue.
