Gateway problem

[Manoj Misra]

I have just configured network on a HP 11.00 machine. I have provided gateway address in the netconf file. Initially when I do net start it is able to ping the external hosts but after sometime (say 1 min.) it is not able to ping any of the external network hosts but can ping the hosts on the same network. The same configuration (with different IP address) is working on 10.20 machines. Any one have the reason and solution.
Many Thanks !

After ./sbin/init.d/net [sto|start] check th gateway with netstat -rn,if you have problem reboot your system.

Hi,

HP-UX 11.00 features "Dead Gateway Detection", which means that the system will remove the default route after a certain interval if it cannot ping the default gateway.
You can disable this feature with ndd:

# ndd -set /dev/ip ip_ire_gw_probe 0

To set this param to 0 at boot time you have to modify /etc/rc.config.d/nddconf:

TRANSPORT_NAME[n]=ip
NDD_NAME[n]=ip_ire_gw_probe
NDD_VALUE[n]=0

where n is the first available number, starting from 0.

You might want to install the latest ARPA transport and STREAMS patches to make sure ndd is up to date and supports all possible configurable parameters.

HTH.
