  • Installation Issues / TCP Dump

    That would explain some things.

    My server is behind a firewall. What is the recommended procedure for remote access where only port 80 and 443 are available?

    I was assuming that it was a localhost <-> localhost for fop2 data and display was over port 80 / 443.


  • Installation Issues / TCP Dump

    I have installed FOP2 on an Elastix Box and have the test connection working.

    /usr/local/fop2/fop2_server --test
    Flash Operator Panel 2 - No valid license found. Demo Mode
    Connection to manager OK!
    

    I also have moved the origianl FOP panel to a new port:

    tcp        0      0 0.0.0.0:4444                0.0.0.0:*                   LISTEN      4103/perl
    tcp        0      0 0.0.0.0:4445                0.0.0.0:*                   LISTEN      10576/fop2_server
    

    If I telnet to port 4445 from localhost - the connection is accepted and I see tcpdump traffic on the loopback interface:

    tcpdump -i lo -n port 4445
    tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
    listening on lo, link-type EN10MB (Ethernet), capture size 96 bytes
    19:45:32.847500 IP 127.0.0.1.51034 > 127.0.0.1.upnotifyp: S 1094391920:1094391920(0) win 32792 <mss 16396,sackOK,timestamp 6198267 0,nop,wscale 7>
    19:45:32.847501 IP 127.0.0.1.upnotifyp > 127.0.0.1.51034: S 1086642151:1086642151(0) ack 1094391921 win 32768 <mss 16396,sackOK,timestamp 6198267 6198267,nop,wscale 7>
    19:45:32.847523 IP 127.0.0.1.51034 > 127.0.0.1.upnotifyp: . ack 1 win 257 <nop,nop,timestamp 6198267 6198267>
    

    When I go to the website however, I get the logon screen and then "One Moment Please...connection to server..attempt 1/2/3" and TCP Dump doesn't report any additional traffic on the lo interface.

    Additionally if I run fop_server with -X 3, it shows lots of traffic with 127.0.0.1 on port 5038, but nothing on 4445.

    Anyone have any ideas? I have been through all the tutorials and have made sure my /usr/local/fop2.cfg matches the asterisk info, but can't seem to get any joy.
