Can't pingForum: Networking Topic: Can't ping started by: joeinnes Posted by joeinnes on July 06 2006,21:13
Ok, I've just installed DSL to the Hard Disk (but this is not a HD install issue), and I have a problem. I have a network set-up that basically comprises three levels.
PC1 and PC2 are Windows boxes. PC3 is the DSL box. Basically, I want to be able to use Samba to share resources between PC3 and PC2. I don't particularly care whether PC3 is connected to the internet or not. So, I boot up PC3, and check to see if it's autoconfigured. Which it hasn't, but that's no big deal, I wasn't expecting it to anyway. So, I type in the details, and try a ping on PC2, which fails. Details are below, I can't figure out what I've done wrong. Oh, by the way, the cable between PC2 and 3 is a crossover cable.
So I try:
And the ping fails. I've tried it from PC2 to PC3 (ping 192.168.0.2), and nothing. No firewalls are running, nothing, it's just not registering. The hardware's fine, and I can ping 192.168.0.2 from that box, and vice versa, so the cards are configured correctly... I'm at a loss... Cheers Joe EDIT: Ok, news... poking around a bit, I get this error message:
Whatever that means. Google doesn't have a clue. Thanks Joe Posted by jonam on July 07 2006,06:38
Joe,Googling just NETDEV WATCHDOG returns quite a few posts from discussion groups. See: < http://www.cs.helsinki.fi/linux/linux-kernel/2002-03/1493.html > and < http://lists.us.dell.com/piperma....11.html > The problem appears to be related to network cards. You haven't said what hardware you are using so in lieu of that information, I would recommend you try another network card based on the information in the above posts. Also, if you want your DSL box to access the internet, you will have to activate the IP passthrough function built into Windows. In Win98SE, it is called Internet Connection Sharing but I don't know how it was implemented in later versions. Regards, Jonam Posted by joeinnes on July 07 2006,07:07
I'm using a Pentium III Coppermine, with 256K RAM. The network card is a cheap U.S. Robotics one, but I had it working under Gentoo. I'd love to try it with a different NIC, but I'm a student, and I can't afford one.Both of these seem to show different NETDEV WATCHDOG errors to the one I'm getting, and so I don't think the solutions are appropriate to me. Thanks for your help, Joe Posted by jonam on July 07 2006,13:17
I did some more searching and one solution to the problem appears to be to disable ACPI power management completely. See here:< http://lists.xensource.com/archive....14.html > DSL normally boots with the cheat code "noacpi" in the boot command line. Suggestion appears to be to add acpi=off to this command line as well. Try this out and see how you go. I have a PIII Coppermine(desktop), 384MB, with Realtek ethernet adapter which I have loaded DSL on as a live CD and it works fine. Another option might be to try DSL 2.1b which has a newer kernel.

I would try making all the IP's on the same subnet.You have one subnet as: 192.168.1.x and the other subnet is: 192.168.0.x PC's like to be on the same subnet unless there is a router between them that knows how to route the tcp/ip traffic between them. There is no real network reason for them to not be on the same subnet is this situation. Give it a shot, it's easy to do before getting too deep into something else. So an example would be: PC1 192.168.1.100 PC2 192.168.1.103 PC3 192.168.1.105 Make your broadcast, netmask, and default gateways the same. Good luck. Posted by joeinnes on July 08 2006,18:28
Ok, thanks for the help guys, but still nothing... I tried both suggestions (acpi=off, and all the same subnet) and neither worked.I've heard that there's a problem with this particular kernel... is there any way to upgrade the kernel? Thanks Joe Posted by jonam on July 08 2006,21:59
Joe,That was my other suggestion. Load DSL 2.1b which has kernel 2.4.31 compared to more recent versions of DSL which have 2.4.26. Alternatively, you could try DSL-N which has the 2.6 series of Kernels. Regards, Jonam Posted by green on July 09 2006,04:52
Gotta be hardware related. Get some cheap used $2 nic cards and replace 'em.

I think I'm gonna get DSL-N, and I'm fairly confident it's NOT a hardware issue, the card works. It's just not working properly under DSL. If Gentoo can make it work, I don't see why DSL shouldn't be able to.Thanks, I'll let you know when there's news Joe |
