No access to the local network (Suse 9.2)
 

Hello! I've got SuSe 9.2 and a Realtek 8139 networkscard, and I can't access my local network! I can't play any games at all on LAN and I can't access the local domain either.

I get an IP and I can access internet without any problems at all.
Anyone have a clue?

Could you post the IP configuration? From what you said, it sounds like you have a router, acting as a DHCP server. Is that correct? If not, where is the DHCP server you got the IP address from? While you are at it, post the output from /sbin/ifconfig

For lan communication, your machines need to be on the same sub-network; unless you go through a router to connect the boxes.

Improper netmask causing all local traffic being forwared to gateway by default?

O.K. so far so good. Your machine belongs to a private sub-net 192.168.1 and the mask is O.K. at 255.255.255.0. Your machine is 28.

Could you answer the other questions. Have you got a router, or a system doing the routing. From what I see, you have a router, but I would like to know for sure.

As I understand it, you can get from 192.168.1.28 to the internet. Please confirm that. You have been sending and receiving packets. You can see the counts.

What are the IP addresses of the other machines you are trying to get to locally?

Yes, I use a router.
Yes, I can get too the internet.
And the IP of another computer on the network is 192.168.1.251 (the router is 192.168.1.1)

Some more things to do, ping the other machine and see if it responds. Since games are not working, I would guess the remote will not respond. If it does, then I believe it is not a networking issue.

Check the mask on the remote machine to make sure it is set to 255.255.255.0. If is not, that could be you r problem. I would also check your router configuration, for net mask, and the number of IP's it allows at one time. I have mine configured to allow only 5, since that is the maximum I expect at any one time.

Do you have a default route set? It should be 192.168.1.1 ( default to the router).

Nope, it doesn't respond.
I have the right masks on all computers, the default route set is 192.168.1.1 :/.

Gah I don't know what the problem might be :(.

Can you ping the router?

If yes, you should be able to since you can get to the internet, most routers have a facility to ping from the router to the device. Confirm that is working.

Sounds to me as if you have a configuration problem on the router. It may not be forwarding the packets on the internal lan.

I can ping the router and the other computers in the network can see eachother but not me.

This is so stupid, why don't it work? :(

I also have the same problem. Also, i can get to update my suse, it checks for mirrors and then gives me error. How can i ping?

zenith_zth,

You can ping the router, can you ping from teh router to the other device? In order to test that, you have to get into the router, most routers for home use allow this. Open a web browser, and enter the IP address of the router. I think yours is 192.168.1.1. This may get you a log on screen, if security is configured. If it is not, it may take you to the configuration screens.

Most home routers, and even larger ones I have worked with have a screen for pinging from the router out to devices.

If that works, you have a routing issue with the router. All teh legs work, but not end to end. There may be a filter blocking you. If you are not the administrator of the router, you may have to talk to that person, and see if they can confirm what we need to know. If pinging from the router to the deivice does not work, thaen that needs to be solved.

Please post the results, and we can go on from there.

The ping command is run from the command line. Type "ping (the ip address you want to get to)"

example: ping 192.168.1.1

If it works ti will look like :

PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.
64 bytes from 192.168.1.1: icmp_seq=1 ttl=250 time=0.629 ms
64 bytes from 192.168.1.1: icmp_seq=2 ttl=250 time=0.623 ms
64 bytes from 192.168.1.1: icmp_seq=3 ttl=250 time=0.623 ms

--- 192.168.1.1 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 1998ms

If you get 100% packet loss, then it failed.

I can tell you from my own experience that SuSE seems to have a major issue with local networking. I never got it working and quit using it because of that. My situation was almost identical to yours. It works fine with Debian, Ubuntu and (Slackware - except printing - see my post on that). Go figure.
