gateway pinging problem
i have installed new system with 11.23 version,
i given all the required entry in /etc/rc.config.d/netconf (ip,netmask and gateway as 10.4.102.17,255.255.255.0,10.4.102.1) now i am not able to ping the gateway(10.4.102.1) from server itself.
Any one can guide me.

Re: gateway pinging problem
a) Use 'set_parms initial' to configure the network on any HP-UX box.
b) ping hostname / ping your ip - Both OK? If yes then NIC is up and function.
c) netstat -rn - obtain gateway ip - ping default gateway. OK? If no then check cable connection.

The gateway system may be down or there may be a network disruption.

Re: gateway pinging problem
If that's true, you must make sure HP-UX's "Dead Gateway Detection" feature is disabled.
For example, see this thread:
http://forums.itrc.hp.com/service/forums/questionanswer.do?threadId=182649
If Dead Gateway Detection was already triggered when you disable it, you may have to delete and re-add the gateway to the system's routing table, to get the route to work again:
route del default 10.4.102.1 1
route add default 10.4.102.1 1

Re: gateway pinging problem
route delete default 10.4.102.1
route add default 10.4.102.1 1
Have you contacted your network administrator? Can they verify that a ping response is enabled for your gateway?
How about the basics? Run lanscan and look at the NamePPA. If there is only one LAN port used, then the PPA number is probably 0 (lan0). Run lanadamin and type these commands:
lanadmin
lan
ppa 0
display
quit
In the display listing, make sure that the Status lines are both UP:
Administration Status (value) = up(1)
Operation Status (value) = up(1)
If you see:
Operation Status (value) = down(2)
then the cable is not connected or the gateway port is dead or disabled.
