Solaris

The error is in the hostname.eri0

It should only contain the name of the interface, in your case:

lvccirt03

But now you have

192.168.209.83 lvccirt03
Remove the IP.

Make sure you have this entry in the /etc/hosts:

192.168.209.83 lvccirt03
THen restart networking, that should fix your issue.

Make sure you understand how to configure networking on solaris 10, you can find tutorials on the web .

Good luck

Ok, Juan!
I deleted the IP for the hostname.eri0 file. I restarted network services... and I was able to add the default route! BUT I still can't ping the gateway.

Code:

# /etc/init.d/network restart
configuring IPv4 interfaces: eri0.
Hostname: unknown
# ping lvccirt03
lvccirt03 is alive
# route add default 192.168.209.1
add net default: gateway 192.168.209.1
# ping 192.168.209.1
no answer from 192.168.209.1
# ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
eri0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
        inet 192.168.209.83 netmask ffffff00 broadcast 192.168.209.255
        ether 0:3:ba:2d:54:6a

So it's a little progress! I can apparently add routes now. just still can't get out on the network.

if you cannot see the gateway then:

- the network information you have is wrong (let say IP, Netmask, GW)
- Cable problem
- Switch problem, some switches shut the port down if they detect errors.
- NIC problem
- Might be that the GW is configured to not respond to ping as well, have you tried to ping another box on the same network, and on another network?

If the network information is ok... first thing I would try is take a laptop, configure the same IP information , plug the network cable and try.

Oddly I can ping out to all the other addresses on the routing table I added but I cannot ping the gateway. BUT connetivity has returned as I can get to the server remotely now! So I think that fixed it. Everything seems okay now. I will monitor it for the next couple days. Luckily, I don't need to add any m ore hardware to it! so I won't be shutting it down again.

Thank you everyone!

It is possible that the gateway is configured not to respond to pings. Some of our switches/fw/servers are configured to block ICMP. So it's plausible.

network is unreachable means .. you didt assign proper gateway address .... check once what is the gateway .....

you assign ip address in eri1 interface and add gateway ... then you ping
