I have an HP-UX box and I'm trying to determine why a host can't be reached. I'm trying to reach the host 10.32.13.146

root@hp-ux:/root # traceroute -I 10.32.13.146

traceroute to 10.32.13.146 (10.32.13.146), 30 hops max, 40 byte packets
 1  * * *
 2  * * *
 3  * * *

I already have a route to the network as seen below - 10.32.13.128/255.255.255.128 10.32.32.1.

Does anybody can explain what's wrong with this server and how to fix this situation?

Edit: No problems reaching 10.32.32.25

  • You can't have a gateway (10.32.32.1) that's outside of the subnet. Are you sure that netmask is correct? – depquid Apr 3 '13 at 21:13
  • and you can reach 10.32.32.25? – artistoex Apr 3 '13 at 23:52
  • to say the least, your routing table looks quite unusual. are you sure you are able to get to anywhere 10.32.x.x network ? Please post the contents of your /etc/rc.config.d/netconf file and if there is any other home made scripts that you are using to create additional interfaces and routes, please post them too. – MelBurslan Apr 4 '13 at 2:55
  • The routes look OK to me. Your gateway is on the same subnet, and you have a route through it to your destination. You need to make sure that 10.32.32.1 is actually acting as a gateway, and that it will respond to ICMP ECHO packets. Some admins turn off ping responses. – Kyle Jones Apr 4 '13 at 3:20
  • @KyleJones No, 10.32.32.1 is not in the 10.32.13.128/25 subnet. – depquid Apr 9 '13 at 19:00

For anyone else who runs across this post:

The computer in this situation has 2 network interfaces. One (lan901) is assigned static IP 10.32.32.1 and therefore absolutely is reachable by the computer... duh!
