Hi everyone, I'm trying to connect to the internet with suse 9.3, but have not been able to. When starting up it will say that the dhcp daemon wasn't able to establish an ip address, and that is backgrounding. Eventually it will fail. However, when I type ifconfig in the console, it gives me an ip address. Any help is very much appreciated. --Seth

And what IP is that? What happens when you type route? A little specificity wouldn't hurt. -- _____________________________________ John Andersen

No you certainly aren't. There appear to be a few packets flowing but not many, probably just dhcp requests. Shutdown suse firewall if you are running it. Check your physical connections (wires, etc). Then open two shell windows (as root). In one, type tail -f /var/log/messages In the other: ifdowm eth0 followed by ifup-dhcp eth0 And watch the results. What kind of nic is that anyway? I can't get a match on that mac address in any database. It almost seems like you have a dribble connection, where a few packets get through but not enough for a connection. Often this happens with 10/100 nics that don't negotiate very well. (3com)

Well there you go. This has all the earmarkings of the Classic 3com dribble connection. 3com has a horrible reputation for failure to auto-negotiate speed and duplex settings with upstream devices. Is this plugged into a 10 meg port or a 100 meg port on the upstream device? Can you try a different upstream device, as a test. Or put something between this machine and what ever is upstream. such as a hub or switch to test if that works? There is a way to tell the nic ahead of time what rate to select, but I forget the details. My normal response upon being given ANY problem by a 3com nic is to listen for the Plonk sound it makes when it hits the bottom of the trash can. Nics are under $10 these days and unless you are 50 miles from the nearest replacement I wouldn't waste any more time with it. -- _____________________________________ John Andersen

The physical connections look good. I've tried with a cable I know works, and I get the same problem. I would suggest that you assign a static IP address. You can do this with ifconfig: ifconfig eth0 <address> Your router should be set for 192.168.1.n where 1 < n < 100. Usually routers use 100 to 254 for dynamic. The see if it works.

What are you talking about? I just talked him out of using a static. It masks the problem of no connectivity by letting you THINK you've got connectivity when you DON'T. In his first post He was convinced he had connectivity because he had an IP. Turned out he manually assigned it. When he printed his iwconfig outout it was clear not a single packet had passed and he had no connectivity at all. Its a hardware problem. People who recommend assigning manual IPs on network segments that have a working dhcp server don't know what they are doing. Its not a good way to solve problems. Its deceptive, and disruptive to other users on the subnet. Its unnecessary, and does not solve a cabling problem, or a dribble connection, or a switch problem. -- _____________________________________ John Andersen

What are *you* talking about? The only way to determine if you have connectivity is to actually try to connect to something. Failing a DHCP request attempt tells you no more about the problems of your network than failing a ping, or an attempt to connect to some server. Only the raw rookie would think he had connectivity simply because he has an IP, but forgot it was assigned statically.

The OP already admitted to being a raw wookie. Perhaps you would like to throw a few more insults his way.

I agree with Darryl on this one. If the OP doesn't know how to check for *real* inet access, it's time he learned. And static IP's make for a much simpler network setup.

In any case, I do agree that Seth probably has a hardware problem with his NIC. I also specified that he ping something on his subnet, since his routing table looked to be correct.

I made no recommendations whatsoever. I only pointed out that using DHCP over a static IP has nothing to do with the solution to this problem, contrary to what you inferred in you response to Jerry Feldman. I threw no insults in any direction. I only pointed out that neither DHCP nor a static IP were of any relevance in resolving the problem, contrary to what you inferred. Finally, I have been following the thread, noting that over 500KB had been received on the HIC, while less than 20KB had been transmitted. This, in your response to Jerry, became "not a single packet", but I do not know just what packets you might mean by that. -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com
