Routing

[Balasiu Dan]

Hi!

we have a HPUX 10.20 server with 2 LAN cards (lan0,lan1)
Lan0 is disabled, lan1 active (this is a normal situation).
We had to change the IP Adress and the Netmask for this server, we did it with "set_parms".
After reboot, the default gateway is bound to lan0, the disabled interface, so routing does not work.
(netstat -nr..)
I tried to modify the netconf file, putting the lan1 flag in the ROUTE_GATEWAY parameter.
It did not work!

Can anybody help me?

thanks a lot

Hi Dan,

The ROUTE_GATEWAY should contain the IP address.

If this does not work, perhaps you could post the output from the netconf file and the netstat commands.

rgds, Robin

In the netconf file put the lan1 flag in the ROUTE_DESTINATION[X]="default" parameter. Then try to execute net stop/start.

Try to flush the route tables with
/usr/sbin/route -f.
Then try adding default route like :
route add default 172.16.1.101 1

Hi

You have both interfaces in the same network.
HP sets the routing at the 'first match' basis.

If you do not use one interface set it's IP to match another network (this is rather workaround than a solution).

Generally speaking you shouldn't have two interaces in the same network on HP, I'm affraid.

Good luck

Dan,

Most likely you gave as routing hops "0" during installation.

edit:
/etc/rc.config.d/netconf

ROUTE_DESTINATION[0]="default"
ROUTE_GATEWAY[0]="x.x.x.x"
ROUTE_COUNT[0]="1"

[Balasiu Dan]

Hi Jansink,

the "hop" number is "1"

thanks

try to disable lan0 in netconf file:

INTERFACE_NAME[0]=lan0
#IP_ADDRESS[0]=172.16.4.100
#SUBNET_MASK[0]=255.255.0.0
#BROADCAST_ADDRESS[0]=172.16.255.255
#LANCONFIG_ARGS[0]="ether"
#DHCP_ENABLE[0]=0
INTERFACE_STATE[0]=down

then reboot.

P.S. recheck your netconf file.
