Title: the opposite of rc.local?
Post by: E-MaN_ on August 30, 2006, 11:16:21 AM

I'm looking for the correct place to be able to notify windows users that the server is going down or reboot.

In rc.local I've put a line: echo server is up! | smbclient  -M winboxes

Now I would like to have somewhere:
echo server is going down/reboot in xx seconds, please logoff | smbclient -M winboxes

I couldn't find this anywhere in the forums.

Write your own script called say, down.sh, that controls this:


#!/bin/bash

SHUTDOWNDELAY=1
DELAY=$[$1-$SHUTDOWNDELAY]

echo Server is going down in $N minutes please save your work and log off! | smbclient -M winboxes
sleep "$DELAY"m
echo Warning:  only 1 minute left before server reboots! | smbclient -M winboxes
shutdown -k +$SHUTDOWNDELAY

exit 0

Put this into a script in say /usr/local (which is on the path) and use this to manage the shutdown (don't forget to make it executable)

Call it with:

down.sh 5

Ok. Great!

And what if I would make that automatic?

Is there a place I could create/replace the template to reboot, so if I'm booting it from the server-panel it will run that part?

The 'action/event' that is attached to the panel button is not templated and would require hacking to acheive what you want, could be done but would not be recommended.

ok then. I can't just add een template to achieve what I want.
I'll stick with your solution then.

Thank you.

That is incorrect.

OP should create a notification script. Add a symlink to that script into /etc/e-smith/events/halt and /etc/e-smith/events/reboot.

Nothing else needs to be done. No existing scripts need to be hacked. No additional ways to trigger a shutdown or reboot need to be created.

Sweet, hadn't thought of doing it that way.

Just goes to show that Charlies intimate knowledge of the innner workings has its benefits.

That's great! Thank you Charly.
I knew it should be easy ;)

I'll implement both suggestions.
