Hi, try telnet to be sure if no one is listening on that port. [root@XXXXX]# telnet yourhost 8000 if you are not running openxcap in debug mode, check out the messages to see if your xcap server is really not listening. Later on just set up the Root URI properly on both, the server and your client.

Finally (buff!!) I could configure openXcap, after executing openxcap start the log says: [-] Log opened. [-] Starting Open XCAP 0.9.4 [-] Supported Root URIs: http://192.168.1.206 [-] twisted.web2.channel.http.HTTPFactory starting on 8000 And nothing else, no more logs displayed. OpenXcap process is running in the machine: [root@XXXXX]# ps -ef|grep xcap root 926 1 0 18:02 ? 00:00:00 /usr/bin/python /etc/rc.d/init.d/openxcap start But no one is listening in port 8000, neither before executing xcap nor after. I havent found any error in any log so I dont know what is going on. Anyone can help me? Thanks. Gregorio
