IP address help-unable to ping or traceroute

I had a request to change the IP address of a printer, since the old IP was no longer pingable. The new IP is on a different segment and administered by another network group. I'm not able to ping the new IP, nor traceroute to it. With the traceroute I can get past our firewall but no further. I can ping this IP from our other servers and from a dos prompt, but not this one particular server.

traceroute 10.162.250.165
trying to get source for 10.162.250.165
source should be 10.130.70.145
traceroute to 10.162.250.165 (10.162.250.165) from 10.130.70.145 (10.130.70.145)
, 30 hops max
outgoing MTU = 1500
1 10.130.70.2 (10.130.70.2) 4 ms 2 ms 1 ms
2 10.16.2.41 (10.16.2.41) 1 ms 1 ms 1 ms
3 *

I tried deleting the entry from arp table, but it says not found:
arp -d 10.162.250.165
10.162.250.165 (10.162.250.165) -- entry not found

I think the problem is past us, but our network guys thinks its on the unix box.
 
sure you are using the right gateway for getting to your printer? Perhaps you have to add a new route ...

rgds,

Can you ping/traceroute other addresses in that particular segment from your server?


HTH,

I tried added a route and am still unable to ping or traceroute.

No I can't ping/traceroute to other address in this segment.
 
I'd show a traceroute output from another server that CAN reach the address and the traceroute output from this server which gets blocked at the firewall to the network people. Perhaps then they give in and start investigating what is blocking your server.

Why don't you talk to the network admin guy! coz there might be some setup needs to be done on the router connecting your segement with his!

another thing sometimes someone needs to configure the new priter's (network card) NIC with the new ip! check the possibility of this as well!

Regards,
Khalid
 
I've spoken to our network guy and he says the problem is with my Unix server since he can ping the IP from windows servers and I can ping the IP from other Unix servers.
 
This problem has been fixed. Problem was with the way the IP was being translated at the firewall for this particular server.
