<br><font size=2><tt>I worked on a Linux system and had a similar symptom
for a couple different problems.</tt></font>
<br>
<br><font size=2><tt>1. The first problem was the multicast configuration
of the network. On my system it worked if we enabled IP forwarding
and also enabled multicast specifically. I combined all the suggestions
I'd seen on this list and websites, and this combination of commands solved
the problem on my system. (Although there could(?) be some security issues
with enabling IP forwarding; I couldn't really say whether or not it's
a "good idea.")</tt></font>

<br><font size=2 face="Courier New">$> /sbin/route add -net 224.0.0.0
netmask 240.0.0.0 dev eth1 </font>
<br><font size=2 face="Courier New">$> echo 1 > /proc/sys/net/ipv4/ip_forward</font>
<br><font size=2 face="Courier New">$> /sbin/ifconfig eth1 multicast</font>
<br><font size=2 face="Courier New">$> netstat -r -n</font><font size=2><tt><br>
</tt></font>
<br><font size=2><tt>2. The second problem was that after a software update,
the "camera" I had began sending RTP packets which indicated
they were RTP version 1.0 packets and not version 2.0 packets. The
RTP packets were being discarded because they were mis-labeled. (I'm not
sure if this was LIVE555 behavior or the behavior of some other part of
our system now. It's been awhile.)</tt></font>
