I am having a bit of a problem. I did an update two days ago, and ever since I have lost my Internet connection. My local network is fine as I can remote into the other PC’s, and they have Internet access. In fact, I have SSH -X on to one of my headless boxes in order to launch Firefox to get to the forum.
I am fairly new to SuSE linux, but have been using *buntu for the last 6yrs or so… but am not sure what to look for as it’s almost as if port 80 is blocked… but the firewall is off.
Hi guys, thanks for the replies… here is the info you’ve asked for:
What is the result of:
/sbin/route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0

cat /etc/resolv.conf

There is something more than mere nameservers.
The Ping test to an IP address returned 100% loss, which means that a problem exists which must be resolved before considering name resolution… unless of course outbound ICMP is blocked.
Since your default gateways appears to be set and <assuming it’s correct> then I think you need to take a look at your DG/Firewalling device. Perhaps it’s setup to filter for clients, eg by MAC address if this is a home router.
If DG is a corporate/enterprise, then you may need to consider whether network authentication is required (and much more).

After the OP responded, I double checked that the IP was correct(could be a
senior moment on my part). Ping also failed here after the OP responded, and
the IP was no longer listed by nslookup. That IP was working again this morning
and was again listed by nslookup. Google must have rotated that server out
between my post and the time the OP could try the IP.
Anyway, I don’t think “forums.opensuse.org” changes their IP; so you should try:
ping -c3 130.57.66.6

Yes, I considered all of that, but discarded it because…

This happens a lot, especially with sites as big as Google. For what it’s
worth, pinging Google’s own DNS severs is very reliable (unless, as tsu2
mentioned, ICMP is blocked) and also gives you as couple of
easy-to-remember IPs for testing wherever you are: 8.8.8.8 or 8.8.4.4

True… historically it hasn’t changed often, but there are more-reliable
servers to use, like those which are not primarily accessed by a domain
name (DNS servers, for example; yet another reason I use Google’s DNS
servers).
