Hi there,

I've got a 3com 905B NIC hooked up to my *surfer cable modem and trying
to configure linux to use the cable to access the net. It detects the card
fine. I'm able to ping the machine..but after that I can't get anywhere ..
not even ping the gateway.

I'm using RH5.2.... Some information that may be relevant:

IP Address 24.3.137.123
Gateway 24.3.137.1
Computer name cc675029-b
Domain name narltn1.nj.home.com
subnet mask 255.255.255.0
DNS server 24.3.144.33

I entered this information into the relevant fields in netcfg... but still
no go... Any help will be most appreciated.

Instead of this, I can also use DHCP...but that's also a no go as well. I've
read all the available FAQs , HOW-TOs.
Thanks!

I hate to go for the obvious, but it has stomped me for a day:
have you tried resetting your cable modem? It stores your ethernet card's
hardware address and will only allow connections from that card.

Here is what you do:
disconnect base T cable from modem
Press reset (small button on the back)
wait until the lights settle
insert cable again
press reset
wait until the lights settle
try pinging the gateway

enjoy if it works

I don't really think this applies in this case... It's the same card I use
for win 98 on the same machine... wouldn't that be the same hardware?

Wellllll..... with Roadrunner we use DHCP - Roadrunner, Redhat, and DHCP nice
mix. Have you checked out the cable modem newsgroup - comp.dcom.modems.cable

search for some type of login script.

Luck,

You are right, my advice doesn't apply. What exactly happens when you ping
the gateway?
I assume your interface is active... What does ifconfig return?

I.e. mine returns

lo Link encap:Local Loopback
inet addr:127.0.0.1 Bcast:127.255.255.255 Mask:255.0.0.0
UP BROADCAST LOOPBACK RUNNING MTU:3584 Metric:1

TX packets:24 errors:0 dropped:0 overruns:0

RX packets:19077 errors:0 dropped:34 overruns:0
TX packets:11636 errors:0 dropped:0 overruns:0
Interrupt:10 Base address:0x300

I'm not a guru, but I think I can help you with setting up one computer if you

By the way, do you plan to set up ip masquerading? That's my next objective,
after I get my cdrom working . This is my problem with cdrom - any advice?

mount -o ro -t iso9660 /dev/cdrom /mnt/cdrom
mount: the kernel does not recognize /dev/cdrom as a block device
(maybe `insmod driver'?)

insmod isofs did not help.

The following command works for me. You might want to try it:

mount -t iso9660 /dev/hdxx /mnt/cdrom

where xx is the drive and the partition (ex. My PC is /dev/hdc1 where CDROM is
primary drive on secondary controller).

When I ping the gateway... it stalls.. until I have to press ctrl-c to exit.

I have had the same problem and have gone back to using an older isa card.
The only other thing that I noticed is that when pinging anything with the
3c900 is that the cable modem was flash (implying that the card was sending
packets, but I never got any returned). This problem has persisted from
kernels 2.1.12x -> 2.1.132.

Try mounting the device that is soft-linked by /dev/cdrom. In my case, it is
/dev/hdc.

In your original post, you said your IP address was 24.3.137.123. The above
ifconfig output says that your IP address is "inet addr:24.3.137.85". I'd
start by fixing that.

Once that's fixed, I'd be concerned with your HW Addr of all 'F's. Then, I'd
look at your collision rate.

Have you entered the DNS IP addresses of your ISP into
netcfg?? Also, enable IP forwarding under routing......this
should do the trick....

This is not good... It looks like the MAC address on the NIC is either blown
or unreadable. The all "F" address is the Ethernet broadcast address. Have
you tried to flash upgrade this NIC recently?

Not sure, but I initially had problems with my 905B on both RH 5.1 and RH
5.2... Again, still not sure what is causing those problems, but I have got
around them by building a kernel with the 3c905 (Vortex/Boomerang) driver
configured to be compiled-in to the kernel rather than built as a loadable
module, which is the default.

It has worked flawlessly since.

Oh, and the symptoms were as you describe. (Actually, "network unreachable"
messages when you try to do anything on the wire, which makes sense, since the
problem, whatever it is, is resulting in the interface not being correctly
configured via "ifconfig".)

Please add the DNS IP address in the file /etc/resolv.conf
Try pinging DNS first to check whether it works.

Hope this helps
