Greetings,
I've created my first launchd script. It's for OpenVPN2. Here are the files I've created so far:
devo:/opt/local/etc/LaunchDaemons root# ls -l org.macports.OpenVPN2/
total 16
-rwxr-xr-x 1 root admin 957 Oct 30 23:06 OpenVPN2.wrapper
-rw-r--r-- 1 root admin 1026 Oct 30 23:39 org.macports.OpenVPN2.plist
The Wrapper
-----
#!/bin/sh
. /etc/rc.common
load() {
if [ -d /System/Library/Extensions/tun.kext ]; then
kextload -q /System/Library/Extensions/tun.kext;
else
echo "tun.kext not found in /System/Library/Extensions/"
fi
}
StartService() {
load; # first load the module
if [[ $( kextstat -l | grep -q 'tun' )$? == 0 ]]; then
/opt/local/sbin/openvpn2 --config /opt/local/etc/ovpn/server.conf --writepid /opt/local/etc/ovpn/ovpn.pid --daemon OpenVPN2
/usr/bin/logger "OpenVPN is loaded"
else
/usr/bin/logger "tun extensions is not loaded."
fi
}
StopService() {
if [[ $( kextstat -l | grep -q 'tun' )$? == 0 ]]; then
kextunload /System/Library/Extensions/tun.kext # first unload the module
fi
pid=`cat /opt/local/etc/ovpn/ovpn.pid` # get the pid number
if [ $? -eq 0 ]; then
kill $pid
fi
}
RestartService() {
StopService "$@"
StartService "$@"
}
RunService "$1"
the .plist which is an: ln -sf /opt/local/etc/LaunchDaemons/org.macports.OpenVPN2/org.macports.OpenVPN2.plist /Library/LaunchDaemons/....

However, there are two issues that I can't seem to be able to manage right now.
The first is that OpenVPN does not start at boot while the module is loaded succesfully. When I login to the system and kill daemondo, it relaunches itself and ovpn works fine. I suspect that the problem is en0. Launchd tries to launchd openvpn before en0 comes up. That's why I put the NetworkState keyword, but it does not seem to effect *any* startup script. I had issues with dnsmasq also in the recent past.
The second problem with this script is that when I unload it via launchd it does not kill the process. Launchd unloads the script and (probably) will not be launchd (if -w is added) in the next boot but daemondo keeps running the process nevertheless. Is this a normal behaviour?
I'm not *that* worried about the second. I'd prefer to have a solution about the first one, which is the most important for me.
Best regards & thanks in advance
