by We have 1 Sparc 20 (Solaris 2.4), with normal ethernet (le0) and fast
ethernet (hme0) interfaces, connected to the rest of the net via le0.
hme0 connects to a concentrator, which in turn connects to three
Ultra 1s (Solaris 2.5), via their fast ethernet (hme0) interfaces.
These Ultras form a subnet of their own; the fast ethernet card of the
SS20 is also on this subnet, and is designated as the gateway (defined
in /etc/defaultrouter on the ultras). All machines are more or less
well-patched. We use NIS+. So ...
----------- }
| le0 } department subnet
SS20 } }
| hme0 }
concentrator } local subnet
| | | hme0 }
U1 U2 U3 }
All the machines can ping each other. The SS20 is fully connected to
the net, no problems there. The problem is that the Ultras cannot ping
machines outside their subnet ie other local subnets, the Internet.
(They can, however use static routes ...)
Now, the basic reason is that the SS20 is not acting as a router.
For some reason, routed is not starting up at boot, even though it has
3 interfaces. I've even created /etc/gateways to force it to start
routed
althought that shouldn't be necessary. Does anyone know why it might
not be starting?
Starting routed manually after boot doesn't help. Nor does also starting
rdisc on the router and/or hosts ... rebooting an Ultra after starting
routed manually on the SS20 doesn't seem to help either.
All IP numbers are defined in /etc/inet/hosts. All the interfaces are
up. The netmask is defined in /etc/inet/networks. Netstat -rv shows
that all gateways and netmasks are properly defined.
Oh, the other thing I should mention is that prior to a recent reboot
of the SS20, the networking worked fine. The last time I rebooted the
SS20 (over 3 months ago), I recall having a similar problem ... which
I solved fairly easily by manually starting routed ... AS I RECALL.
I didn't document the problem, nor did I write it into the rc
scripts ... just forgot about it. So there is a solution, but I must
have lost a few brain cells as I can't work it out now!
