Hello, I installed the Kannel port on my FreeBSD box, and it seems like a bug or somethig, I had to manually create the kannel user, and it seems like have to create the pid files as well... this is the error that now I am getting when trying to start Kannel:
radius# /usr/local/etc/rc.d/kannel start
Starting kannel_bearerbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_bearerbox.pid: No such file or directory
Starting kannel_smsbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_smsbox.pid: No such file or directory
Starting kannel_wapbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_wapbox.pid: No such file or directory

Well... I decided to create manually the pid files, and after trying to start the kannel daemon again I got these errors:

radius# /usr/local/etc/rc.d/kannel start
Starting kannel_bearerbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_bearerbox.pid: Permission denied
Starting kannel_smsbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_smsbox.pid: Permission denied
Starting kannel_wapbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_wapbox.pid: Permission denied

Then I chowned the pid files to kannel user and finally the kannel services were started:
radius# chown kannel *.*
radius# /usr/local/etc/rc.d/kannel start
Starting kannel_bearerbox.
Starting kannel_smsbox.
Starting kannel_wapbox.

The thing now is that each time I restart the box, I get the same "Permission denied" error with the pid files, how can I permanently fix this?

Thanks in advance.

pid files? what (exactly) is that? ([i guess it's like serverauth.xxx, when X starts)
Does that process have write permission on directory it uses pid-files?

Thanks for the response, as I am new on this I had to look on google that a PID file is and according to PidFile (http://daemons.rubyforge.org/classes/Daemons/PidFile.html) this is a pid file:
A Pid-File is a file containing the process identification number (pid) that is stored in a well-defined location of the filesystem thus allowing other programs to find out the pid of a running script.

Daemons needs the pid of the scripts that are currently running in the background to send them so called signals. Daemons uses the TERM signal to tell the script to exit when you issue a stop command.

I have installed many port files before, but this is the first time that I had to create manually the process user and the PID files, maybe that's why the process can't access the PID file, because I did something wrong, or because the bug in the port make file or bad port setup...

How can I have that process to have permanently permissions to its PID files?

why did you need to create new user for deamon?

anyway
man chmod (http://www.freebsd.org/cgi/man.cgi?query=chmod&apropos=0&sektion=0&manpath=FreeBSD+7.0-RELEASE&format=html)

chmod u+rwx /directory/with_pid_file
chmod u+rw /directory/with_pid_file/pid_file_itself

or if you need to change group permission use "o" instead of "u".
you can use bough..... read man i gave you

also if you haven't already change pid-files and/or pid-files directory owner/group
man chown (http://www.freebsd.org/cgi/man.cgi?query=chown&apropos=0&sektion=0&manpath=FreeBSD+7.0-RELEASE&format=html)

oh, I forgot to chmod the /var/run/kannel with the -R option to make the command recursive...

Thanks!
And I created manually the user kannel because the port setup didn't create it...

well, probably if it didn't create it you didn't need it...
anyway, does it work now?

The reason I started this post is because just after installed the kannel from the ports distribution, I got this error:
radius# /usr/local/etc/rc.d/kannel start
Starting kannel_bearerbox.
su: unknown login: kannel
Starting kannel_smsbox.
su: unknown login: kannel
Starting kannel_wapbox.
su: unknown login: kannel

Then I created the kannel user, and then the error was this:
radius# /usr/local/etc/rc.d/kannel start
Starting kannel_bearerbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_bearerbox.pid: No such file or directory
Starting kannel_smsbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_smsbox.pid: No such file or directory
Starting kannel_wapbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_wapbox.pid: No such file or directory
Then I created the /var/run/kannel directory and its pid files, in my try to solve the problem, after that I got this error:

radius# /usr/local/etc/rc.d/kannel start
Starting kannel_bearerbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_bearerbox.pid: Permission denied
Starting kannel_smsbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_smsbox.pid: Permission denied
Starting kannel_wapbox.
/usr/local/sbin/run_kannel_box: open: /var/run/kannel/kannel_wapbox.pid: Permission denied

Now, I chowned the /var/run/kannel folder and its pid files to kannel user and finally the kannel services were started:
radius# /usr/local/etc/rc.d/kannel start
Starting kannel_bearerbox.
Starting kannel_smsbox.
Starting kannel_wapbox.

Now I realized that there are something that can be a potential issue:
In the top command it display all the services running as root, and the kannel services are running as kannel... look:

Can be that a potential issue?

i don't think so, probably more like a security measurement
but i'm not security expert
