Ok, I have modified the /etc/init.d/openvpn script to support both the original Gentoo symlinked style and the multiple .conf file style. 

The script is below. 

Best, 

Steve 

#!/sbin/runscript 

# OpenVPN start/stop script 
# Adapted to Gentoo by James Yonan 
# Modified by Steve Fink to support /etc/conf.d/openvpn 
# and to support multiple .conf files or Gentoo style symlinks 

# USAGE: 
# If the file openvpn.conf exists then it is assumed that you are 
# using the Gentoo style symlinking way of starting 
# 
# If the file openvpn.conf does not exist ie you have your files named 
# server.conf client.conf or anythingelse.conf then all tunnels are started 

# This has been modified so it does the following if no openvpn.conf 
# file exists: 
# 
# - Starts an OpenVPN process for each .conf file in $CONFDIR 
# 
# - If /etc/openvpn/xxx.start exists for a xxx.conf file then it executes 
# it before starting OpenVPN (useful for doing openvpn --mktun...). 
# 
# - If /etc/openvpn/xxx.stop exists for a xxx.conf file then it executes 
# it after stopping OpenVPN (useful for doing openvpn --rmtun...). 
# 

# OpenRC options 
opts="start stop restart" 

# Determine which variables to set for Gentoo symlinked or multiple .conf files 
if [ ! -e /etc/openvpn/openvpn.conf ]; then

Natanael, 


Thanks for the feed back. 



I believe I do understand the Gentoo symlink approach. I tested it with this script and multiple VPN symlinks and it works fine, provided that the main openvpn file is openvpn.conf. 


I chose to look for the openvpn.conf because the default file is openvpn.conf and acf-openvpn creates openvpn.conf when the system is configured via the web browser. If you have a better method, please advise. 


I was thinking we would have to modify the documentation on the wiki to explain the two different methodologies and how to configure both for multiple tunnels. Currently the wiki shows only the method I use which does not work for the original init.d script. 


I created a pid directory for openvpn when using the non-symlink method for the purpose of organization of the .pid files and keep /var/run from having potentially dozens of openvpn .pid's strewn about. I was trying to make the symlink method as close to what was currently happening as possible, this can be changed to /var/run/openvpn as well if you like. 


I moved it after sshd because I've seen times where OpenVPN failed and stopped anything further from starting. Failing to start before sshd would lock an admin out of sshd, therefore unable to connect and fix the problem. I believe removing before netmount was an oversight. 


Best, 


Steve

Finally I took some time to look at it. I still think the script needs 
some work.

I'm not sure you really understand how the gentoo symlink approach 
works. Gentoo style symlinks means you can have multiple .conf files. 

ln -s openvpn /etc/init.d/openvpn.server 
ln -s openvpn /etc/init.d/openvpn.client 

will use server.conf and client.conf in /etc/openvpn dir. 

You start the server.conf setup with '/etc/init.d/openvpn.server start', 
you start the client.conf with '/etc/init.d/openvpn.client start' and 
stop them similarily. 

This works prefectly fine without any /etc/openvpn/openvpn.conf

you could have a gentoo link style system 
with no /etc/openvpnc/openvpn.conf file 
at all, a /etc/openvpn/anythingelse.conf and a 
'openvpn.anythingelse' symlink in /etc/init.d that points to 'openvpn' 

Then you 'rc-update add openvpn.anythingelse' and on boot only the 
anythingelse.conf will be started.

Checking for openvpn.conf is bad since you could have a gentoo style 
symlink without any openvpnc.conf.

Why not use same pid directory for both gentoo style all-or-nothing 
style?

Why does it need to start after sshd? 
Why did you remove the "before netmount" (which i assume is needed if 
you want mount a network filesystem over openvpn tunnels)

I think script will choke here if PIDDIR is really zero. (maybe not but 
older versions of ash did so. should be in "": if [ -z "$PIDDIR" ]....

I dont think that info is useful. You normally dont mess with pid file 
locations (why would you?).

I dont think we need to tell that defaults are beeing used.
