Script on startup

Jean Samarani — Tue, 25 Jan 2011 11:49:38 GMT

Hi Guys,

I have the below scripts that I would like to run on start up on hp-ux 11i v2 but the routes are not being added automatically.

#!/sbin/sh
/usr/sbin/route add net 10.1.136.0 netmask 255.255.255.0 10.1.156.36 1
/usr/sbin/route add net 10.1.16.0 netmask 255.255.255.0 10.1.156.36 1

I have added the script under /sbin/rc3.d/
and the permission are 744.

my runlevel is 3 :

#who -r
. run-level 3 Jan 23 20:34 3 0 S

Can anyone advise what could be the issue ?

thanks a lot for your usual support.

Jean

What is the name of the script?
All rc(1m) scripts should be under /sbin/init.d/. Then you should symlink them under the appropriate run level:
ln -s /sbin/rc3.d/nice-name /sbin/rc3.d/S###nice-name

$ ll /sbin/rc3.d/
S100nfs.server@ -> /sbin/init.d/nfs.server

Anything in /etc/rc.log?

Hi,

Have you tested them manually (from prompt) to ensure that are reachable?

After this you must create in /sbin/init.d a file with the following content:
#!/sbin/sh

RVAL=0
case $1 in
start_msg)
echo "Adding extra routes"
;;
'start')
/usr/sbin/route add net 10.1.136.0 netmask 255.255.255.0 10.1.156.36 1
/usr/sbin/route add net 10.1.16.0 netmask 255.255.255.0 10.1.156.36 1
;;
'stop')
/usr/sbin/route delete net 10.1.136.0 netmask 255.255.255.0 10.1.156.36
/usr/sbin/route delete net 10.1.16.0 netmask 255.255.255.0 10.1.156.36
;;
*)
echo "usage: $0 {start|stop}"
RVAL=1
;;
esac
exit $RVAL

And finally, from /sbin/rc3.d you must create a symbolic link name with "S" prefix that aims to /sbin/init.d/ to start procedure, then in /sbin/rc0.d you must create a similar symbolic link with "K" prefix to stop procedure, this is optional because when the server go down this route definitions will be off.

Rgds.

All you're doing is adding routes. Why have a separate script? Add them into /etc/rc.config.d/netconf.

Hi Jean:

You might want to review the 'rc(1M)' manpages which document the requirements for start/kill scripts.

Regards!

All start/stop scripts must honor 4 parameters, not just 2: start stop start_msg stop_msg

If you do not provide the start_msg and stop_msg, then your system shutdown screen will be filled up with dots .............

However, using an rc (start/stop) script is definitely the wrong way to set a permanent route. As mentioned before, you edit the netconf file in /etc/rc.config.d to add routes.

The netconf file approach to add routes for subnets didn't work that's why I have used the script to add them .
