Subject:    running tmda-ofmipd as a daemon
From:       Andrew <andrew () arda ! homeunix ! net>

[Download RAW message or body]

I've prepared a patch that adds an option to tmda-ofmipd '-D, --daemon' 
that puts the program into the background. With this option, you don't 
need to use an '&' at the end of a command string to background 
tmda-ofmipd. The impetus for this patch was that I was having problems 
starting tmda-ofmipd from an init script on my Mandrake 8.2 box. There 
is a thread on the tmda-users mailing list that describes the problems I 
was having more fully.

So, here is the patch. I hope people find it useful enough to be 
incorporated into the distribution. Comments are welcome, but if you 
post to tell me what I did wrong, you have to tell me why it's wrong and 
how to do it right.

Andrew
