Routing Tables

Post by Fairlig » Thu, 05 Sep 1996 04:00:00



I've got two machines.  One is OS5, and one is SCO QuickStart.  At reboot,
there are a bunch of incorrect routes coming up on the QuickStart box.  I
have searched damn near everywhere on that box, and cannot find where
they're coming from.  Does anyone know?

The weird thing is that they're coming up oddly, like one is for the
machine's IP#, routed through localhost.  Another is another machine on the
net, routed through localhost.  It's causing problems, and I need to remove
these from whatever script or file they're in.

Incidentally, on the regular OS5 machine, I need to set a default route.
What is the "correct" place to set the default route to the router?

HELP!  

Thanks!

The file you need to edit is /etc/tcp.  In this file the ifconfig brings up the
interfaces and the route commands will administer the routes.

1. How Do Routing Table Entries Get Added to Routing Table at Bootup?

I have, what I think, is a simple question for the TCP/IP guys out there
who are familar with routing tables on AIX 4.1.5/4.2.1 in an IBM SP
environment. Or maybe not.

I have recently noticed that when I execute a 'netstat -r' on a
particular node in the SP environment, there are routing table entries
that I know I didn't put in there. I have to delete these "unwelcomed"
entries and re-add the correct ones. This is undesireable and maybe a
quick crash course in routing tables is justified. These unwelcomed
routing table entries seem to be automatically added right after I have
IPL'ed the node in question.

How did these routing table entries get added in the routing table? Does
anybody know the process?

Thank you in advance for your responses.
