Unkown Host


Hello,

I have a small Network looking like this.

Internet(kabel)---R----S1----S2----s3----Box

Why all those Switches? The router has only 4 ports, I need 8.
So I need S1 (near the router). Some connections of S1 go over a wireless Bridge to other buildings. On the router there is just one box, the one I use to configure the router (and of course S1) In the part of the building where S2 is, there are some boxes and some printers so S2 has 5 ports - one is used for the connection to location 3 where I have 3 boxes (also 5 ports).

I recently assembled 2 boxes , one with debian and the other with suse.
When they start up, they get an ipadress from R (dhcp) no delay, works fine. Then they go on the internet for a timeserver connection. Also no trouble reported. But when the box is ready and I try to get Google in the browser my luck is over. After a long wait I get the message UNKNOWN SERVER......

I put the connection from S3 direct on the router, but that does not help.

If I ping to the router, I get a nice response. Pinging to other boxes or printers somewhere in the network is also no problem. I replaced S3 with a brandnew one, but this also does not work.

Can anyone give me a clue?

Thank you CloudBuilder

all that to say you can't resolve external addresses? do you have dns servers listed in /etc/resolv.conf? can you ping them? can you ping other sites by IP?

That's the problem.

Obviously I have made a mistake. In this file are the ip's from my router - and so I get no external addresses.

I edited the file and put the addresses from the name servers in it and then BINGO!

I must have done something wrong in Yast when I configured the nic. I must read my manuals again!

For what I know, I should not explicit use those addresses because they can change ( I'm connected to a cable network)

Thanks for the quick answer.

After trying and ....
Reading a lot of docs, I still have some troubles.

The problem is that the resolv.conf file is replaced at boot.

The replacement does not contain the dns info ......

I set up some NO switches in /etc/sysconfig/network/config.

Now I can use the internetbrowser and get updates.

But I'm still full of questions what I did wrong. I know it is the setting of the internet and more specific the dhcp management, but If I put the good addresses in it it still keeps overwriting the resolv.conv

Perhaps some one can give me another hint.
The strange thing is I have the configuration with the router for about 2 years and had 4 linux boxes working without any troubles. Recently I replaced a view and made some new installs and now they all are at war with me.

It should be very simple but perhaps I am looking to deep in it.

Thanks in advance.
