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:
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/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/S85tcp: ifconfig rtr0 126.96.36.199 -trailers netmask 255.255.0.0 broadcast 188.8.131.52
/strcf: cenetb ip /dev/rtr0 rtr0
/tcp: ifconfig rtr0 184.108.40.206 -trailers netmask 255.255.0.0 broadcast 220.127.116.11
/rc0.d/K85tcp: ifconfig rtr0 18.104.22.168 -trailers netmask 255.255.0.0 broadcast 22.214.171.124
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:
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
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:
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
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:
Where x equals the interrupt you want SCO to look for the card at. Rerun tests three and four.
