System looses default gateway on system reboot

William Hill_2 — Mon, 12 Dec 2005 13:29:19 GMT

I am running a L3000-7X server with HPUX 11.0
every time we reboot the server we lose the default gateway, this can be fixed by using the "route add default xxx.xxx.xxx" command after reboot, I have checked the /etc/rc.config.d/netconf file and it appears to be ok, any suggestions on why this is happening and how we can fix this. Thanks

Shalom William,

You can use SAM to set this.

or the set_parms ip_address

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

GATEWAY=ipaddress of gateway

ex

GATEWAY=192.168.0.254

Do not save an extra copy of netconf in /etc/rc.config.d/ back it up elsewhere. If there are two copies they both get processed.

Mr. Protter, enclosed is my netconf file with all the comment lines stripped out

# netconf: configuration values for core networking subsystems

HOSTNAME="ugunhl16"
OPERATING_SYSTEM=HP-UX
LOOPBACK_ADDRESS=127.0.0.1

INTERFACE_NAME[0]=lan0
IP_ADDRESS[0]=xxx.xxx.xxx.xxx
SUBNET_MASK[0]=255.255.255.0
BROADCAST_ADDRESS[0]=xxx.xxx.xxx.xxx
INTERFACE_STATE[0]=up
DHCP_ENABLE[0]=0

GATED=0
GATED_ARGS=""

RDPD=0

RARP=0

ROUTE_GATEWAY[0]="xxx.xxx.xxx.xxx"

ROUTE_DESTINATION[0]="default"
DHCP_ENABLE[1]=0

SUBNET_MASK[2]=255.255.0.0
INTERFACE_NAME[2]=lan2
BROADCAST_ADDRESS[2]=xxx.xxx.xxx.xxx
INTERFACE_STATE[2]=up

ROUTE_DESTINATION=[4]="net 2.1.0.0"
ROUTE_MASK[4]="255.255.0.0"
ROUTE_GATEWAY[4]="xxx.xxx.xxx.xxx"
ROUTE_COUNT[4]="0"
IP_ADDRESS[3]=xxx.xxx.xxx.xxx

INTERFACE_NAME[3]=lan3
BROADCAST_ADDRESS[3]=xxx.xxx.xxx.xxx
INTERFACE_STATE[3]=down
DHCP_ENABLE[2]=0
DHCP_ENABLE[3]=0
Note: The value for "ROUTE_GATEWAY[0]="xxx.xxx.xxx.xxx" " is the value for my default gateway. Do I still need to add this line to the netconf file
GATEWAY=xxx.xxx.xxx.xxx
Thanks for your help
Bill

Check the directory /etc/rc.config.d.

There is a file there called netconf where you can set this information.

William,
double check that there is no other file with similar name: netconf or netconf_blabla.. in the /etc/rc.config.d directory. at times it can pick up a file named "netconfold" before the "netconf" file name.

Edit the /etc/rc.config.d/netconf and add the gateway once again. If you are not sure use sam to that.

Check the permission/owner of /etc/hosts file and add the gateway.

Use netstat -nr to see wheteher it is set on boot.

Sometime people use hexadecimal in it. But use decimal instead.Or you have a typo in it.
