Hi, Does any one know how to get cnclinux networked to my desktop. I spent over an hour on the phone yesterday with Drew at Ajax and we couldn't get it to work. First tried with a crossover cable, then with dhcp with crossover cable. now trying with a router and straight thru cables the desktop seems to work but the linux gives me a "dhcp failed" with a bunch of mumbo jumbo following. i have a 3com pci card. How do i know that its function properly in linux? BTW in pretty much illiterate with linux but with detailed intruction, no prob. BTW the mill works fine, i just have to get it networked. Todd

Unfortunately, detailed instructions are not likely to be forthcoming. Troubleshooting network connections typically involves a lot of experiment and observation (much of which you have probably been through with Drew).

Getting the router and straight cables was a big step forward. It will give you additional diagnostic tools, and will also allow you to introduce a third computer as a tiebreaker if you need to (i.e. if A can't connect to B, then see if A can connect to C, or if C can connect to B).

My guess is that the provided Linux kernel does not contain a suitable driver for your 3COM network card. You may find some useful information in the dmesg.txt file, which is among the files generated when you do F7/Utility, F7/Report. Look through it for a block of messages that talk about "eth0". Post back here with a copy of all that you find there. For example, here are the messages from a system that I am pretty sure correctly connects to a network:

It is experimentally probing for various known network card types. It checked for cards with the 3c515 chipset and didn't find any. It checked cards with the cs8900 chipset, and didn't find any. That check wasn't very graceful, and generated all the "incorrect signature" messages that look alarming but don't mean anything. Then it checked for a card with the Realtek RTL8139 chipset; found one; noted that it is sharing an IRQ (which is probably okay); and started up the driver.

Show us what you find in that part of your dmesg.txt. Also look for a section that mentions dhcp, zcip, and/or "promisuous mode". That is probably after "freeing unused kernel memory" and before various "usb.c" items.

Also let us know what you have in cnc10.net (with password x'd out if you prefer).

What do you get when you enter the command ifconfig at a Linux command prompt?

If it turns out that the kernel does not have a driver that recognizes your card, it will probably be easier just to find a cheap RTL8139 card to use instead.

Thanks I'll check it out tomorrow. Todd BTW, I think you are right about the 3com driver.

Markl, here is that file i don't know how to configure it so it looks like a mess. Todd

I GOT IT!! Irealized my moboard had an on board lan that was being covered up by the backing plate. Todd
