I tried two different Intel eexpress ISA NICs, both of which were detected
just fine and work in other machines in the network. I also tried a 3com PCI
card, which is detected normally. The machine can ping itself, but nothing
on the other side of the cable. (As I said, the cable is good, as are two
others I tried.)
How can I capture the output of ping and ifconfig so I can send it
verbatim to you guys?

Use the redirection operator into a file. 'ping > outfile'
You can then attach the files to an email.

Guys,
I just set up another RedHat 6.2 machine in my classroom. Though
ifconfig shows the NIC just fine, the machine won't get on the network. It
refuses to ping or be pinged by anybody, and there are lots of transmit
errors. (The other 14 PCs all work fine.) I tried 2 known good network
cables and a diferent NIC with no change in the response.
Since this machine had plenty hard drive space, I told the install
program to put on a lot of stuff that isn't on the other ones. Specifically,
I had it load apache in case I wanted to play around with it. I'm wondering
if this couild be the problem. Does anybody know if apache has some sort of
security that needs to be configured to allow communication? Or should I
just start over with the same basic configuration that's on the other PCs?
Thanks,
Dave Prentice

Which NICS did you try ? In the event they are 3Com, there are known issues
with 3Com and RedHat 6.2's drivers for them.

Also, what was the exact verbage of the error ?

Your problem certainly doesn't have anything to do with apache. If you're
getting "transmit errors" I'm guessing that's at the packet level and
therefore far lower-evel (lower layer to be precise) than apache.
apache has nothing to do with overal communication over the network. just
the web. If you can't ping, you got bigger problems.

What do the outputs of ifconfig -a, route -n, and lsmod say?

Not that I'm aware of. It's simply an application that has no bearing on your
network --- it just takes advantage of your network if you have one
configured. In other words, you can have no NIC at all, and apache will work
fine, off the loopback interface.

Or should I just start over with the same basic
> configuration that's on the other PCs?

Yeah.

Speaking of the loopback interface, here's a basic rundown on how to
troubleshoot networks:

Ping localhost / 127.0.0.1
Ping your IP
Ping other machines on your LAN
Ping your gateway
Ping something beyond your gateway (e.g. 208.194.248.8)
Ping a domain name beyond your gateway (e.g. mail.fastband.com)

(Heh, the fastband IPs are just about the only ones I can remember, so don't
sweat it...)

Anyway, this scheme will tell you where your problem lies, or at least how
far out from the loopback can you go before problems start happening.

Mozzel tov!
