UdpAppender uses UdpClient?
Hi,
We're looking to use the RemoteSyslogAppender from a bunch of Windows
services running on the same machine, sending log events to one server
listening to one port. Looking through the source, RemoteSyslogAppender
inherits from UdpAppender, and UdpAppender uses a UdpClient object. If
I try to start two applications on the same machine aiming to send log
event to the same remote sys log I get an error saying "only one usage
of socket address is normally permitted".
I've seen this exception before in my own work with sockets, and I got
around it by using a Socket instead of UdpClient, but I suspect you can
set the ExclusiveAddressUse property as well. I can't see a way of
setting this property through the appender though.
Is there any way I can use multiple UdpAppenders/RemoteSyslogAppenders
sending to the same address/port on the same machine?
Thanks
Ian

Ahh, that does explain something. I'll give it a go and see if it
works.

Are you setting the LocalPort for the RemoteSyslogAppender? You
shouldn't be. In the InitializeClientConnection of the UdpAppender you
should see:
if (this.LocalPort == 0)
{
this.Client = new UdpClient();
}
else
{
this.Client = new UdpClient(this.LocalPort);
}
If localport is 0 then the client is created w/out a port, so you should
get a random (and unused) one. If you've set the local port, then yes,
the second attempt to open will fail since you've already bound
something to that port.
