Network problem

[Timmeh]

We're having problems in our office with a networking issue. We thought maybe we had a bad NIC but put another in and had the same problem. 3 of us can't figure it out.
Below is a description of the problem. thanks for any help

My network is down. When I used ping 127.0.0.1, the system output the message: Network is down. When I used "ifconfig up", I get the message "ifconfig: ioctl (SIOCGIFFLAGS): no such interface".

And I found the error while I was starting the SCO system as follows.

Checking tcb …

Checking protected password and protected subsystem databases …

Checking ttys database …

The system is coming up. Please wait.

I assume the new NIC is the same type as the old. I also assume you checked the obvious things like IP addresses in the config, network cable, and hub/switch connections.

What were you doing to the system before it went down? Did the networking stop in the middle of processing? Did you have a system crash? Did the problem occur as the result of a reboot?

This definitely sounds like a network card problem. Since you've already tried replacing the card, my advice is to remove and reinstall all of the network card protocols, drivers, and software.

 

[Megabitman]

what type of card?

 

[Timmeh]

The original card is a 3Com card and the other we tried was an Intel Pro 100S server adapter. Either way we still can't ping the loopback address which seems that it may not be a NIC issue?

I hate to ask such a mundane question... Did you check for the driver for the Intel card on the Caldera site? I didn't see what version of sco you are running. I've had troubles running some of the Intel cards, so I tend to stay with 3com as it seems that they have been better supported.

I had the same problem.
I found out that it matters if you don't have SCO TCP/IP installed. This requires either,
SCO Openserver 5.0.5 "Enterprise" or "Desktop" software.
If you are trying to configure tcpip on a "HOST" version, you won't get very far. The is no support for tcp/ip unless you purchased this option from SCO.

Not sure what steps you took when you added the new card. SCO requires that you completely remove the old driver and hardware in netconfig process; then relink the kernel then add the new card from scratch and relink again.

Just a thought
