Hi I don't know how to use the setuid command.<br>
<br>
I were trying to find some documentation or tutorial and BTW I red the
manual information for the setuid function.<br>
<br>
I tried to add the following line at the rtpproxy init script but I
only got an error:<br>
setuid ser<br>
<br>
Could anybody give me a hand?<br>
<br>
Regards<br>
<br>

Typically, you will run rtpproxy with the same user (or at least group)
as ser or you can change permission on the socket file after starting
rtpproxy in your init script (chmod to be more targeted).<br>

I found the problem. As Samuel have said the problem is with socket
permissions.<br>
<br>
When the RTPProxy is already running and I modified the permissions or
owner to the rtpproxy.sock file it works but as soon as I restart the
deamon the permissions <br>
go back again to the original permissions.<br>
<br>
This is something to do with how the rtproxy is creating the .socket
file at the time it starts and it defines the permissions to srwxr-xr-x
for the user and group equal to root.<br>
<br>
So as I have been running SER with user and group as ser, SER can't
talk to the socket.<br>
<br>
I need to modify the way like RTPROXY runs in other to start the daemon
with another user or with different permissions for the socket file.<br>
<br>
In the meantime I applied the "umask 000" command at the
"/etc/init.d/rtproxy" file and it works but it modifies the .pid file
too.<br>
<br>
Is there a way to tell rtpproxy daemon to run with a different user for
example user ser ?<br>
<br>

RTPROXY is running as it default:<br>
root 2332 1 0 Jul09 ? 00:00:00 /usr/sbin/rtpproxy<br>
<br>
And SER is running as follow:<br>
ser 4612 4575 0 Jul09 ? 00:00:00 /usr/sbin/ser -P
/var/run/ser/ser.pid -u ser -g ser<br>
<br>
And the socket File is like this:<br>
-rw-r--r-- 1 root root 5 2006-07-09 02:45
rtpproxy.pid<br>
srwxr-xr-x 1 root root 0 2006-07-09 02:45
rtpproxy.sock<br>
<br>
I already tried changing the owner and group for the rtpproxy.sock but
it didn't work<br>
<br>

something's wrong with the socket permissions.... which are the
owner/group which SER and rtproxy are running??<br>
<br>
Check wether SER user has permissions wnough to access the rtproxy
socket.<br>

Hope it helps,<br>

Maybe you can help me with this.<br>
I'm using Debian sarge r3.0 and SER apt packages (0.9.6)<br>
<br>
I was looking at the CVS Repository if there was something related to
this behavior with RTPPROXY and I found the following annotation for
ser/rtpproxy/main.c on July 4: <br>
<pre>Since we are now opening control socket in non-blocking mode, there is race condition between accepting stream connection on unix domain socket and availability of data on the socket. Patch it by doing read() in a loop until we actually get the data. While I am here, allow V command to take extra argument, which we don't process but put into the log file. This allows to pass some extra information from the client (SER in this case) such as PID number for example.
</pre>
Does it have something to do with my problem? BTW I found a bug posted
too at the <a href="http://lists.debian.org" target="_blank"

<br>
Yes, that happens when the nathelper module is unable to contact the
rtppoxy either because it is not running or it is an old version and is
incompatible with your nathelper. <br>

Try this instead: <br>
