SCO UNIX TROUBLE SHOOTING HINTS

Support Bulletin: 4080 Rev: A

Abstract: This document provides basic instructions for obtaining information to be used in trouble shooting a SCO Unix installation.

Trouble Shooting Instructions:

1. Boot machine with Dos and run diags. Making sure to write down card configuration (I/O, Interrupt, mem, dma, etc.). Does card pass Diags, if yes go to step two. If not resolve hardware problems and retest. When card passes Diags go to step two.

2. Boot SCO machine and login. From Command line type:

cd/etc

find . -type f -print | xargs grep rtr0 >/tmp/rtr

Print the file rtr. It should look something like this:

/perms/rtr:rtr F644 root/root 1 ./usr/lib/netconfig/init/rtr0 01

/perms/rtr:rtr F644 root/root 1 ./usr/lib/netconfig/info/rtr0 01

/perms/rtr:rtr F644 root/root 1 ./usr/lib/netconfig/remove/rtr0 01

/conf/cf.d/mdevice:rtr0 ocIs iScH rtr 0 83 1 4 -1

/conf/cf.d/conf.c:/* 83*/rtropen,rtrclose,nodev,nodev,nodev,0,rtrinfo,"rtr0",

/conf/cf.d/sdevice:rtr0 Y 1 5 1 9 0 0 0 0

/conf/node.d/rtr0:clone rtr0 c rtr0

/conf/sdevice.d/rtr0:rtr0 Y 1 5 1 9 0 0 0 0

/rc2.d/S71rtrmon:dev="../dev/rtr0"

/rc2.d/S85tcp: ifconfig rtr0 128.1.7.41 -trailers netmask 255.255.0.0 broadcast 128.1.255.255

/strcf: cenetb ip /dev/rtr0 rtr0

/tcp: ifconfig rtr0 128.1.7.41 -trailers netmask 255.255.0.0 broadcast 128.1.255.255

/rc0.d/K85tcp: ifconfig rtr0 128.1.7.41 -trailers netmask 255.255.0.0 broadcast 128.1.255.255

Have the customer fax this file to us to review.

3. If customer has TCP/IP installed on the SCO machine and is part of a TCP/IP network. From the command line type:

arp -a

This will test to see if the card can see other cards on the TCP/IP network. If so the card is at least talking and communicating on the Token-ring. For additional help with the ARP command refer to the

user manual of the supplier of the TCP/IP product.

4. If the customer has TCP/IP installed on the SCO machine and is part of a TCP/IP network. From the command line type:

ping xxx.xxx.xxx.xxx

Where xxx.xxx.xxx.xxx is the IP address of a known working machine running TCP/IP and is connected to the Token-ring. It does not matter whether the machine is Running SCO or not, all that matters is that the machine has TCP/IP up and running. A valid command would look something like
this:

ping 128.1.7.41

For additional help with the PING command refer to the user manual of the supplier of the TCP/IP product.

5. If the SCO machine reports that the Interrupt is not the interupt the card is set to, then from the command line type:

cd /etc/conf/sdevice.d
vI rtr0
/x
x
ZZ
cd ../cf.d
/link_unix

Where x equals the interrupt you want SCO to look for the card at. Rerun tests three and four.
