UDPXY v. 1.0 (Build 21) standard



  • Hi,

    If you have time and desire to help, I need your help.

    I have installed udpxy v. 1.0 (Build 21) standard on pfSense 2.0.1-RELEASE-pfSense (i386), together with the IGMP Proxy.
    WAN (re0) 10.218.104.92
    LAN (rl0) 172.22.22.0/24
    I do not know why, but the provider broadcasts multicast stream from 150.158.231.1

    Over IGMP Proxy client, using udp :/ / @ 239.2.3.xxx: 1234 is taking multicast well, but as you know over wi-fi, even with enabled multicast.
    UDPXY created a log file udpxy.log udpxy, but it always remains empty. I can see the logs only through pfSense/status/system logs.
    On startup UDPXY runs through udpxy.sh with a such parameters udpxy_flags = $ {udpxy_flags-"-a rl0-m re0-c 20-M 120"}
    Can you recommend a maximum performance parameters (-H,-B,-R, etc.) for better viewing?

    The client connects uses http://172.22.22.3:4022/udp/239.2.3.75:1234


    tcpdump-ni re0 igmp

    Over the status (web: http://172.22.22.3:4022/status) I have:

    Active clients:
    Process ID          Source                    Destination        Throughput
    15643        172.22.22.99:49889      239.2.3.75:1234        N / A

    The client does not see the picture. After restarting of pfsense router - the video stream goes. After switching to the next different channel - the video stream goes well. But if I return to previous channel - no video stream. But video stream on the WAN still remaining:

    14:48:08.180322 IP 150.158.231.1.49152> 239.2.3.38.1234: UDP, length 1316
    14:48:08.182658 IP 150.158.231.1.49152> 239.2.3.38.1234: UDP, length 1316
    14:48:08.184980 IP 150.158.231.1.49152> 239.2.3.38.1234: UDP, length 1316
    14:48:08.187311 IP 150.158.231.1.49152> 239.2.3.75.1234: UDP, length 1316
    14:48:08.189647 IP 150.158.231.1.49152> 239.2.3.38.1234: UDP, length 1316
    14:48:08.191966 IP 150.158.231.1.49152> 239.2.3.38.1234: UDP, length 1316
    14:48:08.194315 IP 150.158.231.1.49152> 239.2.3.75.1234: UDP, length 1316

    But udpxy does not supply to client a unicast. After a while, the stream appears, but not for all channels, as over IGMP Proxy.

    For example over IGMP Proxy using udp://@239.2.3.16:1234 client's stream appears.
    But over udpxy using http://172.22.22.3:4022/udp/239.2.3.14:1234 - nothing and result on log is such:
    udpxy [42873]: read_buf: read: Resource temporarily unavailable

    Observed pattern: in some cases UDPXY starts to work, when I used IGMP Proxy before for that specific chanel.

    Thanks in advance for your help.
