default gateway does not establish

[Terrence]

When I reboot my servers, (11i) the default gateway does not establish. If I do a /sbin/init.d/net start, it will then create the route. Also a route add default etc, fails. Only the net start command restores the default gateway. Here is the pertinent part of the netconf file.

ROUTE_DESTINATION[0]="default"
ROUTE_MASK[0]="255.255.0.0"
ROUTE_GATEWAY[0]="10.1.1.1"
ROUTE_COUNT[0]="1"

Has anyone seen this before?

Terrence,

Must have took a while to boot the server...
Are you trying to enable the gateway/ipadress on the right interface. Check lanscan for ppa numbers and do a lanadmin ppa number and check if the interface is up.

HTH,

Only one lan interface lan0. It's up and configured correctly. Even before default gateway is established, there is connectivity via the same subnet so I know the card is working.

Hi,

Are you able to ping the gateway?

Gideon

[Terrence]

Yes, but it's on the same subnet so it doesn't need a default gateway to ping it.

You mention "route add default" fails, what if any, error message are you getting?

This doesn't sound like a dead gateway detection issue, but you can try pinging your gateway from the server in question to see if it accepts ICMP requests. If not, you need to be sure dead gateway detection is turned off.
If this is the issue, add the following to /etc/rc.config.d/nddconf
NDD_NAME[0]=ip_ire_gw_probe
NDD_VALUE[0]=0

You can also run this from the command line:
ndd -set /dev/ip ip_ire_gw_probe 0

Hi,

Let me get this straight. When the server boots, the gateway is not set, when you type route add default the gateway is not set, Only with a net start the gateway can be set...
When the server starts net start is called. Could you post the network part of /etc/rc.log?

I'm attaching my rc.log. Unfortunately I cannot reboot my server right now so I can recreate the message. It might be this:

#route add default 255.255.0.0 10.1.1.1 1
usage: add destination [netmask mask] gateway [metric]

[Terrence]

I've already got dead gateway detection turned off in nddconf. In any case, yes I can ping the gateway before I have it set as the default route. The server and the gateway are on the same subnet.

[G. Vrijhoeven]

Hi again Terrence,

That you can ping the gateway is not to check if the gateway works, but to check if it responds.

The net start command seemed to work in the boot process.

Configure LAN interfaces
Output from "/sbin/rc2.d/S340net start":

The route command should be:

/usr/sbin/route [-f] [-n] [-p pmtu] add [net|host] destination [netmask mask] gateway [count]

So i would try:

# route add default 10.1.1.1 1

Hi,

I assume you know you can check the settings with netstat -r[n]

Hi,

Try commenting the line ROUTE_MASK[0]="255.255.0.0".
or make it look like ROUTE_MASK[0]=""

This field is always an optional field. I think this is creating you the trouble while assigning the default gateway.

With best wishes

Terrence,

make sure you haven't got another routing entry in your netconf file with the same array index, i.e. more lines that look like this:

ROUTE_DESTINATION[0]=
ROUTE_MASK[0]=
ROUTE_GATEWAY[0]=
ROUTE_COUNT[0]=

any other routing entries should have an incremented index for the array (1,2,3 etc,) otherwise /sbin/init.d/net only pays attaention to the last entry with a given index. Take a look at the bottom of the file where SAM has a tendency to add entries.

HTH
