[Live-devel] ip 0.0.0.0 in rtps url

[Henrik Nilsson]

We are a group of students who are building a robot with a live mpeg4 
feed and we have some problems to get the live test servers to run on 
the robot.

Our robot is built on a PC104+ 1,2GHz with a slimmed slackware 
installation which gets its ip etc over dhcp.

When we run test*Server the rstp URL we are given tells us to connect to 
ip 0.0.0.0? If we check ifconfig everything looks allright, connecting 
over ssh to the ip from ifconfig works fine too.

What can be the problem that makes the test servers think the ip of our 
robot is 0.0.0.0 and how can we fix this?

This is what ifconfig tells us:

ifconfig
eth0      Link encap:Ethernet  HWaddr 00:E0:6C:3A:00:A3
       inet addr:192.168.2.101  Bcast:192.168.0.255  Mask:255.255.255.0

       RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

This is what testOnDemandRTSPServer tells us:
