Martin,
most probably you cannot get anything via ngrep because:
1 - the outbound message is not sent
2 - the inbound message may contain a domain name which leads to
0.0.1.244 via DNS.
try to monitor the DNS traffic also to see if this address comes up.
what version of openser are you using?

bogdan

Bogdan,
You are right it is the destination. I added the following to
udp_server.c when the error occurs:
LOG(L_ERR, "sa = %d, %s, %d\n", to->sin.sin_family,
inet_ntoa(to-> sin.sin_addr), ntohs(to->sin.sin_port));
Which logs:
sa = 2, 0.0.1.244 <http://0.0.1.244>, 5060
This address is clearly invalid. Interesting thing though is that I
ran an ngrep to see if I could locate a message that contains this IP
and could not find one:
ngrep -p port 5060 | grep "0.0.1.244 <http://0.0.1.244>"
The above came up clean even though the log kept reporting the error.
Any more ideas?
Martin

Martin,
after all, it look the root problem is the destination address - the
detection of the egress socket (triggered by mhomed) also fails
because
of an Invalid Argument (as originally).
my guess is that an invalid ip or port is used for sending the
message.
If you cannot track this down, I can try to prepare a patch to
print the
destination address/port in case of error.

Thanks for your reply Bogdan,
There is definitely both UDP and TCP listening:
Starting openser: openserListening on
udp: xx.xx.xx.xxx [xx.xx.xx.xxx]:5060
tcp: xx.xx.xx.xxx [xx.xx.xx.xxx ]:5060
Aliases:
......
Is it possible that there is simply too many messages for the server
to handle?
At the moment the server is configured with:
children=20
tcp_children=2
and an ngrep suggests quite a few messages per second.
Thanks
Martin

Hi Martin,
the last error you posted says you want to forward something
using UDP
(proto 1), but there is no listen socket for
UDP.
can you check is there is no UDP listen configured on your
openser?

Recently we

sendtoparameters one possible reason is the server is

Now the errors suggests a binding to localhost, however our
openser.cfg has the following:
listen=eth0:5060
After a brief search we came across a couple of over people
having a
