Set Default Gateway Permanently

[ckchua]

Dear Friends,

I have tried to set the default gateway using SAM and I have problem getting the setting permanently. When server re-booting, the default gateway will be blank.
please advise.

Many thanks

Hello,
Please enter your default gateway address in the /etc/rc.config.d/netconf
Change the parameters

ROUTE_DESTINATION[0]=default
ROUTE_GATEWAY[0]=xx.xx.xx.xx
ROUTE_COUNT[0]=1
ROUTE_ARGS[0]=""
and do a
/sbin/init.d/net stop
/sbin/init.d/net start.

Thanks

Hi,

sam is fine for doing this sort of thing....
usually but .... You can edit the
/etc/rc.config.d/netconf file and change
the following parameters then stop and
start your network, by running the below:

# /sbin/init.d/net stop
# /sbin/init.d/net start

Changes to /etc/rc.config.d/netconf

ROUTE_DESTINATION[0]=default
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]=xx.xx.xx.xx
ROUTE_COUNT[0]=1
ROUTE_ARGS[0]=""

To add your default route at the command line
# /usr/sbin/route add default xx.xx.xx.xx 1
(1 being the number of hops to your router)

The default way to do this is

/etc/set_parms addl_netwrk.

This utility allows you to set the network mask and IP-address, but also DNS and NIS settings. If you don't want to configure the last two, just press cancel. It has a GUI and CLI interface.

[Eugen Cocalea]

Hi,

/sbin/set_parms addl_netwrk

or

edit the file

/etc/rc.config.d/netconf

and change the settings for the '0' route to suit your needs, then restart the network.

There you go.

Also make sure you have only one correct copy of netconf in the /etc/rc.config.d dir, if you have files such as netconf.orig or netconf.old move them to another directory.

[Rita C Workman]

As was mentioned by the folks above the permanent method of setting your default gateway is in the /etc/rc.config.d/netconf file.

Now, since your up and running and want to have the system aware of that gateway address NOW...you would want to enter:

route add default 1

Remember to key that ( 1 ) after the IP...
So, doing this there is no need to recycle anything..your done.

Rgrds,
Rita

I normally put the entry for the machine and its gateway into /etc/hosts, these are the addresses needed to bring the machine up. The rest of the addresses are available from DNS when networking is up.


Sam should work.

Are you getting any errors using Sam?

[Tommy Brown]

I had that happened to me, when in SAM I used the Name of the gateway, and not the IP address. During the boot process it could not resolve the name and left it blank when it finished booting, it was without a gateway... Just a minor lesson learned..

Hi,

Take a look at the thread below,

http://us-support2.external.hp.com/cki/bin/doc.pl/sid=8d3410c102fc6fb2f2/screen=ckiDisplayDocument?docId=200000024605269

hope this helps.

thanks

Ck,

Apart from the comprehensive
suggestions which folks have
given in this thread:
Make sure you are setting
the gateway on the correct
lan interface!


To make sure your network configuration is correct, do

#lanscan -> shows lan interfaces

#lanscan |grep -v Hardware |grep -v path | awk '{print $5}'
-> this will give your
lan interfaces (lan0,lan1..)

check the settings of the interfaces:
#ifconfig
-> this will show the current network settings of the interface.
Make sure it is what you want.

#netstat -nr
-> shows the current routing table. The entry
corresponding to default
is your default gateway
entry and it also shows
the lan interface it corresponds to.

To set default gateway permanent, edit /etc/rc.config./netconf
file and enter the parameters
in the ROUTE_DESTINATION
ROUTE_COUNT and ROUTE_GATEWAY
entries. Also make sure
the subscript of the ROUTE
is the same as the lan
interface you are using.

Hi Everybody,

Thank you for your superb advise. I am confident that I will be able to resolve this issue as soon as I am at site next Wednesday.

Have a nice weekend.

And remember to assign points if this info has helped.

We only work for peanuts, throw a few.

I have checked in etc/rc.config.d/netconf, everything is perfect. The gateway ip is specified but is SAM it does not show the default gateway ip.

I have tried to run /sbin/init.d/net start, everything seems to be okay after executing the net start. I suspect some network process is not executed. How to check net start is executed during server boot-up. Please advise.

Hi,
Check /etc/rc.log file for any error during boot up.
----------------------------
Configure LAN interfaces
Output from "/sbin/rc2.d/S340net start":
----------------------------

Hi,

cd /sbin; ll rc?.d | grep net

You should find a symbolic link (on my 11.0 servers it is /sbin/rc2.d/S340net) pointing to /sbin/init.d/net.

I've seen SAM do some weird things with netconf so I like to edit it by hand. Verify there is no other stanze using the same "instance number" ([0] or whatever you're using for the default route).

Hi,

Actually, my server is using ATM instead of LAN interface.
What shall I check ?

Hi,

Don't know much about these but....
Try and do 'nettl' trace. This may bring up
some interesting things. Also check this
out this link.
