How to add command upon boot ?
« on: September 04, 2002, 10:55:31 PM »
My MRTG and Cacti has now worked flawlessly for quite some time now. I then had to reboot and noticed that the SNMP deamon did autostart during boot.

I would like the command:
"service snmpd start"

to be issued upon boot.

How do I ensure that ?

(I know stupid question if you know Linux but I am not an expert)

I hope anyone can help here.

Thanks,
Jesper

No question is stupid... unless you don't take the time to seek the answer first.

The file you want to modify is /etc/rc.d/rc.local, it's quite similar to the "autoexec.bat" of the Dos days.  Ensure you use the full path to the executable, I don't think rc.local operates with an environment set (please correct me if I am wrong).  I pretty confident this file isn't templated, at least in pre-5.5 I am sure.  Perhaps 5.5 has templated it...

Hope this helped,

Nathan, you've answered the question he asked, but it's not really the best way to do what he wants to do.  A better thing to do would be to make a symlink in /etc/rc.d/rc7.d, like this:

# cd /etc/rc.d/rc7.d
# ln -s /etc/rc.d/init.d/snmpd S95snmpd

This will automatically start snmpd near the end of the sequence whenever the system starts.  The only problem is that this will be removed whenever a console-save is done (because SME regenerates all the links in runlevel 7 at that time).  To take care of this, we'd also do

# /sbin/e-smith/config set snmpd service InitscriptOrder 95 status enabled

This way, SME should rebuild that link along with the others.

No need to template it. Any scripts you want to run should be dropped into /etc/e-smith/events/local - they will be run when rc.local runs "signal-event local".

That did the job. I will place in my personal Howto which is shared among my SME/linux beginner friends.

Thanks a lot,
Jesper
