Debugging a route/gateway problem

[khayr]

From a Solaris box, 10.13.5.212 I am trying to ping another box 192.168.31.42 but get this error:

ICMP Host Unreachable from gateway MyHost1 (10.13.5.212)
for icmp from MyHost1 (10.13.5.212) to 192.168.31.42

Any suggestions as to why this fails. Note, these machines could see each other prior to a power failure.

>cat /etc/gateways
route add 10.0.0.0 -netmask 255.0.0.0 10.13.4.1
>
>ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1

Hi,

Check you router box routing table. Make sure it has enrty for 192.168.*network.

netstat -rn will show your local routing, I'll assume from your >>cat /etc/gateways
route add 10.0.0.0 -netmask 255.0.0.0 10.13.4.1
You obviously have no route from the 10. back to 192. network (localy anyway).
