I just installed 11.0 and am trying to continue configuration. I can’t connect to the internet but I can ping other machines on my LAN and I can ping the router. ifconfig gives me
The firewall obviously isn’t a problem if you are doing outbound stuff.
DHCP is the same since you can ping you obviously have a working IP
address. The problem is probably either your gateway (ip route sh) or
your DNS side of things (cat /etc/resolv.conf). Post the output from
those two commands and let’s see what we can see.
Good luck.

I forgot… your netmask could be hosed too and cause an issue but you
said ‘ifconfig’ showed everything correct so I’ll rule that out. If you
are in doubt, post the output of ip addr sh as well.
Good luck.

Try adding the Name Resolvers’ IP addresses and the Gateway/Router’s IP address by hand – sometimes necessary. It’s in Yast – Network Config.
For a pictorial look at the sequence of PICS 1,2,5,6,7,8 in this tutorial: HowTo Configure a network card in Suse/openSUSE 10.x for LAN and Internet Access.
The so called “DHCP on Steroids”
Thanks for your suggestions. When I looked at /etc/resolv.conf, it was empty except for what looked like the normal starting comments. I added
nameserver 192.168.1.1
search AIF
The first is my router’s address, the second is my Windows Workgroup. But this information disappeared asnsoon as I went through YaST -> Network Devices -> Network Settings -> Hostname/DNS. I added those lines manually to /etc/resolv.conf because the Network Settings GUI did not let me make changes. I can’t check “Change /etc/resolv.conf manually” and can’t add anything to the “Name Servers and Domain Search List” section.
When I ran “ip route sh” I saw
192.168.1.0/24 dev eth1 proto kernel scope link src 192.168.1.13
169.254.0.0/16 dev eth1 scope link
127.0.0.0/8 dev lo scope link
I don’t yet understand what all of that means, but I am very puzzled by “169.254.0.0”. That is not an IP on my network.
I won’t show the result of “ip addr sh” because it looked fine given what I know.
One more bit of information: this machine has two network interfaces. The cable from the router is currently plugged into eth1 and all the tests I’ve performed are on eth1.
I’ve configured eth0 to start on cable connection.
Does Linux want or require eth0 to be used before eth1? Who knows with these machines?

You’re missing your default route.
Check the fourth tab in Network settings. It should probably be
‘192.168.1.1’, the same as your dns, since it’s your gateway/firewall/router.
For future reference, the command to set it manually is:
route add default gw 192.168.1.1
169.254.0.0 is a standard ‘class’ of ip addresses, used when a system cannot
find a dhcp server and does not have a fixed address. This could allow
systems to communicate with some sort of ‘help server’. No idea really. You
usually see these type addresses on windows machines which cannot find a dhcp
server. Linux machines typically just sulk and keep waiting. It can be safely ignored.
oh, in /etc/resolv.conf, the ‘search’ line specifies a default domain name to
search, if one were not given, not a workgroup. ({Chuckle} dns was around
long before windows was!)
As an example, I own the ‘lornix.com’ domain… so my resolv.conf contains
‘search lornix.com’. This means that if I query for ‘saturn’, if it doesn’t
find something that matches exactly, it appends ‘.lornix.com’ to the end and
tries again… thus finding ‘saturn.lornix.com’ (my main machine). Very
handy.

Miracles can occur in the humblest of circumstances. In bash I typed:
“ifconfig eth1 192.168.1.13”
“route add default gw 192.168.1.1” (which responded: “SIOCADDRT: File exists”)
and again I added “nameserver 192.168.1.1” to /etc/resolv.conf.
Before restarting the machine I also installed the new nVidia drivers (and down came a horde of rpm’s not seemingly related to video drivers).
Upon restart “/etc/resolv.conf” contains information modified by dhcpcd (where beforehand it was an empty comment block) and it now contains
“nameserver 192.168.1.1”
I have internet service. Hurrah! Strangely I can also use the Hostname/DNS interface in Network Settings (which was disabled during my previous posts).
Which file is affected by “route add default gw 192.168.1.1”? I ask because I still don’t see any value under Default Gateway in the 4th tab in Network Settings.
Also wondering: which configuration file is affected by the ifconfig command?
