I’m trying to give my computer (has ethernet wired cable connected to router) a static IP but it’s not working. (BTW, I’m using ifup not network manager) Here’s what I do:
YAST > Network Settings > Overview > Edit…
Statically assigned ip address…
I give it 192.168.1.8 and 255.255.255.0.
Hostname I leave as they have it (it’s the name of my computer). Click OK, accept and it all says it went through but now I can’t ping anything. If I change it back to DHCP, I can ping again. What am I doing wrong?
Ah, this appears to be the issue. Pinging an ip address gives a reply. It’s a qualified domain name that does not. But my router doesn’t have any DNS’ set in it because it’s DHCP from the internet provider, so how do I know what DNS’ to use?
Really – hmm. If your internet provider is giving you a DHCP address, they must be supplying a DNS servername as well – otherwise they aren’t doing DHCP correctly IMHO. Check your router’s IP configuration from your ISP (does it have some sort of web-based admin tool) … and look in there for DNS server settings. They should be listed.
If not, then it USED to be that you could use 4.2.2.1 and 4.2.2.2 for DNS as they were kinda like ‘open’ DNS servers, but your mileage may vary … or you could call your ISP and ask them what DNS server IP addresses to use.
You’re not filling in DNS settings, and possibly a default route. Having
an IP address doesn’t mean you have a valid IP address that will work with
the rest of the network, and even if you do it does not mean you setup
things properly to work with the rest of the network (or other networks)
in other ways. Setup a default route (aka. gateway) which should be the
same as your default route when using DHCP, and also set the same DNS
servers as when using DHCP. To get these settings compare the output from
the following commands while in DHCP or static modes:
ip addr
ip route
grep -v ‘^#’ /etc/resolv.conf
Good luck.

The following may work or not for the OP. My own router acts as a DNS if I
set its local IP adress (192.168.178.1 in my special case, the router manual
should tell which it is) into the appropriate field.

Switch back to DHCP for a moment and see what IP of the DNS server You get it should be stored in “/etc/resolv.conf” file. Then with the manual static configuration simply enter the same address and You’ll be fine.
The easy way out is stick to the public DNS servers already provided or use 8.8.8.8 or 8.8.4.4 (google free to use DNSes). It might be that they will work better than your ISPs DNS it may be worse but anyway the difference most likely will be very hard to notice.
