Routing table lost!!

Routing table lost!!

Post by Pradit Pitaksathienk » Fri, 17 Mar 1995 12:17:13



I've problem, 2 days ago 4 times, the Routing table was losted from Sun
workstations, only Sun no effect with Silicon, used Solaris 2.3 and 2.4
,some Sun workstations have no users account except root (data server).
I've not done anything with them and Router, with Router no one accessed.

This is message when they have the problem :

Mar 15 09:21:45 my hostname  in.routed[82]: SIOCDELRT: No such process
Mar 15 09:21:45 my hosyname  in.routed[82]:  dst 0.0.0.0 gw routerIP metric 2

With in.routed ,it ok, still process .
The way I done now is 'reboot' them to return Routing table but it will lost
again and again. (I check from netstat -rn and found it lost).
Please give me suggestion:
1.Where should I point to ,Router or Sun workstations ?
2.Why it happen with only Sun ,not with Silicon or PC ?
3.It happend with all Sun at the same time togather.?? evenif no users access.

1. RH 5.2: Routing table losing default route/gateway

We're running RH 5.2 Apollo, 1 NIC.

Here's what our working routing table looks like:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
206.100.166.128 *               255.255.255.192 U     0      0     1521 eth0
127.0.0.0       *               255.0.0.0       U     0      0       41 lo
default         206.100.166.190 0.0.0.0         UG    0      0     4935 eth0

this box was just setup and configured.  It seems to spontaneously/ramdomly
loose it's default route.

I'm no linux expert so I'm not too sure if this is the right way or not, but
the only way we can seem to get the route back is by doing the following:

route -add default netmask 0.0.0.0 dev eth0
route -add default netmask 0.0.0.0 gw 206.100.166.190 dev eth0

then the table looks like:

Kernel IP routing table

Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
206.100.166.128 *               255.255.255.192 U     0      0     1521 eth0
127.0.0.0       *               255.0.0.0       U     0      0       41 lo
default         *               0.0.0.0         U     0      0       42 eth0
default         206.100.166.190 0.0.0.0         UG    0      0     4935 eth0

Any ideas?

Thanks
