Did you create the file /etc/defaultrouter with the gateway IP adress in it ? Too bad I.T. is not cash business

SUN OS 5.8 is running on intel PII, having 2 NIC cards,
iprb0 is private address and iprb1 is public address. Also created /etc/defaultrouter, this is gateway for my second card. I can ping both IP addresses (iprb0 and iprb1) butnot able to ping gateway "no answer from xxx.xxx.xxx.xxx". I have checked ps -ef|grep routed, it was running fine.any idea how do I proceed further.

Hi,

Try adding a route to that network using the route command. For example:
/usr/sbin/route add -net xxxx.xxxx.xxxx xxxx.xxxx.xxxx.xxxx -netmask xxxx.xxxx.xxxx.xxxx
| | |
This is the network to which | |
you are adding the route | |
| |
This is the ip address of |
the nic in that network |
This is the netmask for that network

Hope this helps!

You shouldn't need any routes to ping the gateway, by definition it needs to be on the same network.

Are you sure you have a network link? Try snoop -d iprb0 for example and see if it is seeing any network traffic, or use ndd to see if link_status is 1. Annihilannic.

1.executed snoop -d iprb0 and iprb1, there was no traffic. but i am not sure about ndd.

2. ndd /dev/ip ipv4_ire_status, found 0 and 1's.

let me know little bit more on this.

Unless you have a very quiet network it sounds like you have a link problem. If your NIC has green network activity LEDs, are they lit? If not, you may have a cable or switch port problem?

ndd -set /dev/iprb instance 0 followed by ndd -get /dev/iprb link_status would tell you the link_status for iprb0.
