Access to port 9000

[tarak]

I'm tying to build OpenSim on a Debian 5 VPS via putty on Windows XP (hope that makes so sense to someone).

I keep getting the following:

09:45:18 - [REGION]: Starting HTTP server
09:45:18 - [HTTPD]: Starting up HTTP Server
09:45:18 - [HTTPD]: Spawned main thread OK
09:45:18 - [HTTPD]: Error - Address already in use
09:45:18 - [HTTPD]: Tip: Do you have permission to listen on port 9000, 0?
09:45:18 - [APPLICATION]:
APPLICATION EXCEPTION DETECTED: System.UnhandledExceptionEventArgs

Exception: System.Net.Sockets.SocketException: Address already in use
  at System.Net.Sockets.Socket.Bind (System.Net.EndPoint local_end) [0x00000]
  at System.Net.Sockets.TcpListener.Start (Int32 backlog) [0x00000]
  at HttpServer.HttpListenerBase.Start (Int32 backlog) [0x00000]
  at OpenSim.Framework.Servers.HttpServer.BaseHttpServer.StartHTTP () [0x00000]

Now two lines of enquiry (actually 3)

1. Is the port blocked at the firewall (as far as I can tell no, though with Nortons Security Suite 2009, it is hard to tell what is going on - also the VPS does not block the port)

2. I've made an error in the associated config files (don't think so, been through them several times, but I'm chasing that through on another forum specific to OpenSim.)

3. There is a port conflict somewhere (obvious)

Now - is there anyway to identify where the blockage or conflict is? What other application is using the port.

I'm not highly Linux skill - skills are pretty poor actually so Mickey Mouse and 'how to suck Lemons' replies are more than welcome.:rolleyes:

Thanks

Another process, probably an earlier incarnation of that http server, is already bound to port 9000.

To verify this, please do as root:

netstat -tunlp | grep 9000

Use the appropiate init script to stop that daemon.
If all else fails, find out its PID and kill it

kill <PID NUMBER>
and if you are really desperate:
kill -9 <PID NUMBER>

Then start again and the httpd server should be able to bind to port 9000

Thanks for that - it is just what I needed
