<p><tt>Hi Pasan,</tt></p>
<p><tt>This is not related to the natping socket, rather to an
inability of the opensips process to open up a raw rocket. Can you
try to run opensips as root, just to confirm it fixes the issue?</tt></p>

<div>Hi Guys,<br>
<div><br>
<div>
<div>I'm trying to use "<span>natping_socket" parameter in
nathelper module to spoof the source ip of the nat
ping from the backup server. But I can't start
opensips with that param set and its failing with
following error. The socket IP I specify is available
on the server.<br>

Using Contact replication and HA</a>,
But I couldn't come up with a
conclusion as discussion there
wasn't complete. Is there a
limitation in using this function ?
There's not much info on the doc. I
even tried with different ports
other than 5060, But result is still
the same.<br>
