Yes, Yast will set those things - based on information from you. But we 
don't know are they set correctly. Some of the previoulsy mentioned 
further questions:

Note - lacking a better means of emphasis, commands which you should 
type e.g. in a konsole session are enclosed in 'quotes like this' The 
'quotes' should not be typed - just what is between them.


1) What is the default gateway address?  [For this discussion, we'll 
assume it's a.b.c.d]

2) Can you ping that address? i.e. what happens when you do  'ping 
a.b.c.d' ? If all is in order, you should get something like:

PING a.b.c.d (a.b.c.d) 56(84) bytes of data.
64 bytes from a.b.c.d: icmp_seq=1 ttl=64 time=50.198 ms
64 bytes from a.b.c.d: icmp_seq=2 ttl=64 time=49.878 ms

3) Is that address correctly configured as your default route? i.e. if 
you do  'netstat -rn' do you get a line of output resembling this

0.0.0.0	a.b.c.d	0.0.0.0	UG	0	0	0	eth0

4) If 2) and 3) are as they should be, you should now get a positive 
response to  'ping 193.1.31.98' which is the IP address of www.linux.ie 
(fingers crossed it won't change sometime very shortly)

5) How are your name servers set up? Do  'cat /etc/resolv.conf' and you 
should see at least one, preferrably two or three lines beginning  
nameserver and followed by an IP address e.g.

nameserver 	e.f.g.h
nameserver	i.j.k.l

You should be able to ping as in 2) both of these addresses i.e. 'ping 
e.f.g.h' and 'ping i.j.k.l'


If all of the above provide positive responses, then your networking is 
correctly setup, and you should now be able to access the Internet by 
name  e.g.   ping www.linux.ie . I suspect from what you have said that 
this is NOT the case. If I'm correct, do let us know where things 
failed in the above trail.

P.S. The next time I am accused me of being short with neophytes I will 
have this email carved in ogham on an oak stick and will beat the 
accuser with said stick.
