hangs on starting eth0

Hi,
When my RedHat box boots it hangs when it tries to bring up eth0. I
have set it up as a static IP (192.168.247.5). How can I figure out
where/why it is hanging ?

If I don't start eth0 on boot, but do it later via ifup eth0 the whole box
hangs (no response from the mouse/keyboard.)

Geoff.

seems you have a hardware problem .. I suggest to test it with another
ethernet device you know it works.

I have tried other ethernet cards with no sucess either, some of them have
booted, however I cannot ping in or out.

But these are two different issues: hanging OS and no working network.

Use a device that doesn't harm your OS
Come back if the network doesn't work. Reasons may be no correct routing
table, work DNS entry etc.

Make sure you have your eth0 IP address defined in your host file. It may
be trying a DNS lookup and hanging.

Just a thought!

Right! Discovered similar problems with my DHCP-client on system shutdown of
the server, cutting off the network-branch I'm sitting on. DHCP has a
timeout in seconds. Static IP times out in minutes.

XP IS a security hole.

I removed the orginal ethernet (remove in bios as on the motherboard)

Added a four port Adaptec PCI ethernet card, when I booted Hardware
discovery
found the new card,

#1
IP 192.168.247.5
Netmask 255.255.255.0
Default gateway 192.168.247.254
Nameserver 192.168.247.1

#2 Do nothing
#3 Do nothing
#4 Do nothing


Then when brining up eth0 it hangs as it did before.

With the Adaptec if I change it to DNS then it boots fine, however I get an
error that there may not be a cable connected, however this is and the hub
(and the card) do have "lights"

damn
but you told, you ..

[..]
> some of them have booted, however I cannot ping in or out.

If I understand it correctly, it means, with such a card you *can*
bootstrap into the system properly .. "only" the network is not up.
Why not starting at this point with `route', `config' etc.?
Pls. correct me if I'm wrong.

power light but no traffic, right? try another cable

you might run `dmesg' for the other messages .. and have a look at
/var/log/messages
