FreeBSD noc 9.0-RELEASE-p3 FreeBSD 9.0-RELEASE-p3 #0: Tue Jul 17 10:47:35 EEST 2012 zaika@noc:/usr/obj/usr/src/sys/gw amd64
udpxy-1.0.21-2
>Description:
If someone watches any IPTV channel (UDP multicast) via udpxy proxy next client can't watch it.
Udpxy rise error "setup_mcast_listener: bind: Address already in use". On RELENG8 I've never seen such issue.
>How-To-Repeat:
Start to watch any IPTV channel via udpxy on FreeBSD 9.0 and try to watch the same channel from another IP.
>Fix:
In the file netop.c replace a few strings in setup_mcast_listener
from:
rc = setsockopt( sockfd, SOL_SOCKET, SO_REUSEADDR,
&ON, sizeof(ON) );
to:
rc = setsockopt( sockfd, SOL_SOCKET, SO_REUSEPORT,
&ON, sizeof(ON) );
