I have a OpenSuse 12.2 box which works great. I am on Comcast for my ISP.
Using the Network Connections UI tool, I am able to setup the IP4 manually.
I setup the internal ip address as 10.0.0.145, netmask: 255.255.255.0, and gateway ip as 10.0.0.1.
I have not setup any DNS servers at all. With this system I can see the internet just fine.
Now I have a OpenSuse 13.2 box which works ok.
Using the Network Connections UI tool, I am able to setup the IP4 manually.
I setup the internal ip address as 10.0.0.150, netmask: 255.255.255.0, and gateway ip as 10.0.0.1.
I have not setup any DNS servers at all. With this system, I CANNOT see the internet at all, but it must be on the internet because I can actually SSH into this machine.
I have setup my Comcast Router, port forwarding, to allow port 22 to this system.
because this system cannot see the Internet, no updates have been done to this system in some time.
Why is it, that with nearly similar setups in Manual IP4V, one system can see the internet just fine, but the other can’t?
I guess I might have to use the Yast2 network configuration to setup the network, make sure I can see the Internet, get the system updates, and then maybe the KDE Network Manager will work again, and I can get away from using YAST2?
Regarding your 12.2 box,
My guess is that despite thinking you set your box up for manual network configuration, you night be setup as a DHCP client.
You can verify this somewhat by running the following in a console and comparing your results with your manual configuration.
ifconfig
Another way to doublecheck your network configuration is to open
YAST > Network Devices
Initially, the default tab is “Overview” – Click the leftmost tab “Global Options” and verify whether it says “Classical Ifup/Ifdown” or “Network Manager.”
Based on the above setting, you can then inspect your network settings in YAST (Classical Ifup/ifdown" or NM (Network Manager).
Whereas IIRC 12.2 by default set up Network Manager as a DHCP client by default,
13.2 now sets up wicked as the default network configuration tool and you may have actually chosen <not> to set up as a DHCP client so without configuring DNS you aren’t able to perform name resolution. Simply perform the following to fix…
Open YAST > Network Devices >Hostname/DNS tab
Enter some DNS server’s IP address in the appropriate field. If you don’t know your ISP’s DNS, then enter 8.8.8.8 which is one of Google’s public servers.
