Hello! Instead of continuing to pull my hair out over this, I figure I’ll appeal to you all. I’m trying to use WMS on a RedHat EL6 server to connect to the MPTS multicast of a Sencore MRD4400, but it appears to continuously time out. From the logs: INFO application app-start _definst_ live/_definst_ INFO server comment - RTPMediaCaster.create[811495456] INFO server comment - RTPMediaCaster.init[811495456] DEBUG server comment - RTPSessionDescriptionDataProviderBasic.rtspSessionTimeout: 15000 DEBUG server comment - RTPSessionDescriptionDataProviderBasic.rtspConnectionTimeout: 4000 INFO server comment - RTPMediaCaster.Reconnector[811495456:live/_definst_:mpegts.stream]: start: 1 DEBUG server comment - RTPMediaCaster#Reconnector.run: reconnectDelay: 100 INFO server comment - HTTPStreamManager.onHTTPRequest: Publish stream successfully started [live/_definst_]: flv:mpegts.stream INFO server comment - RTPSessionDescriptionDataProviderBasic.getStreamInfo[live/_definst_]: URI: udp://239.192.0.200:10000?videoPID=0x310&audioPID=0x300 DEBUG server comment - sdp: v=0 DEBUG server comment - sdp: o=- 1846185774 1846185774 IN IP4 127.0.0.1 DEBUG server comment - sdp: s=WowzaMediaServer DEBUG server comment - sdp: t=0 0 DEBUG server comment - sdp: a=range:npt=now- DEBUG server comment - sdp: c=IN IP4 239.192.0.200 DEBUG server comment - sdp: m=mpegts-transport 10000 RTP/AVP 96 DEBUG server comment - sdp: a=rtpmap:96 MP2T/90000 DEBUG server comment - sdp: a=control:mpegts DEBUG server comment - sdp: a=audioPID:0x300 DEBUG server comment - sdp: a=videoPID:0x310 DEBUG server comment - LiveReceiver.onFlushNotifyClients[live/_definst_/]: false DEBUG server comment - LiveReceiver.flushInterval[live/_definst_/]: 50 DEBUG server comment - LiveReceiver.verboseDebug[live/_definst_/]: false INFO stream create - - DEBUG server comment - RTPDePacketizerMPEGTS.init INFO server comment - RTPDePacketizerMPEGTS.init: Drop incomplete video frames INFO stream publish mpegts.stream - INFO server comment - MulticastTransport.bind[live/_definst_]: 239.192.0.200/10000 INFO server comment - MulticastTransport.bind: multicastInterfaceAddress: /10.0.0.1 DEBUG server comment - MulticastTransport.bind.joinGroup: multicastInterfaceAddress: /239.192.0.200 INFO server comment - RTPMediaCaster.Reconnector[811495456:live/_definst_:mpegts.stream]: done: 1 DEBUG server comment - ServerHandler.handleSessionIdle: idleTimeout: 32 DEBUG server comment - ServerHandler.handleSessionIdle: idleTimeout: 32 DEBUG server comment - ServerHandler.handleSessionIdle: idleTimeout: 32 DEBUG server comment - ServerHandler.handleSessionIdle: idleTimeout: 32 INFO server comment - RTPMediaCaster.streamTimeout[811495456:live/_definst_:mpegts.stream]: timeout:12000 diff:12008 reason:101 INFO server comment - RTPMediaCaster.resetConnection[811495456:live/_definst_:mpegts.stream]: INFO server comment - RTPMediaCaster.closeRTPSession[811495456:live/_definst_:mpegts.stream] INFO server comment - MulticastTransport.unbind[live/_definst_]: 239.192.0.200/10000 sent:0 recv:0 INFO stream unpublish mpegts.stream - INFO stream destroy mpegts.stream - A tcpdump of the interface shows me that the multicast traffic is coming across: 11:36:55.953753 IP 10.0.0.72.3020 \> 239.192.0.200.10000: UDP, length 1316 11:36:55.954327 IP 10.0.0.72.3020 \> 239.192.0.200.10000: UDP, length 1316 11:36:55.954903 IP 10.0.0.72.3020 \> 239.192.0.200.10000: UDP, length 1316 … And I also see these on the interface: 10.0.0.1 \> 224.0.0.22: igmp v3 report, 1 group record(s) [gaddr 239.192.0.200 to\_ex { }] 10.0.0.1 \> 224.0.0.22: igmp v3 report, 1 group record(s) [gaddr 239.192.0.200 to\_in { }] 10.0.0.1 \> 224.0.0.22: igmp v3 report, 1 group record(s) [gaddr 239.192.0.200 to\_ex { }] But ultimately, I can’t ever seem to join the group. Help please! ---

Ping! Can you think of anything else I might be able to check/try/provide to get moving on this? ---

It was a firewall issue. I added “-A INPUT -m pkttype --pkt-type multicast -j ACCEPT” before “-A INPUT -j REJECT --reject-with icmp-host-prohibited” in /etc/sysconfig/iptables and that did the trick. Thanks!
