FMS2 NetConnection question

Dave Williams

2006-06-14, 7:11 pm

Does anyone know where the script is on the FMS server that handles
the rtmp connection? I am having difficulty getting FMS to find Port
80 and I want to trace the actions in the script.

My understanding is that FCS1.5 looks first to Port 1935, then Port
443 and finally tunnels over to Port 80. Is it the same on FMS2?

I've discovered that my application with Simple Connect will find
Port 80 perfectly when the client is behind a firewall blocking Port
1935. However, when I instead use NetConnection(); and APP_ADDRESS =
"rtmp://12.34.56.77/global"; unfortunately, only Port 1935 is
accessible. Port 80 is never found.

I've already made sure the httpcfg.exe isolates Port 80 to IIS on my
first IP and FMS2 is bound to my second IP address.

In fms.ini I have inserted:
ADAPTOR.HOSTPORT = 12.34.56.77:1935,80,443

and in Adaptor.xml, I have inserted:
<HostPort> 12.34.56.77:1935,80,443 </HostPort>

Does anyone know how I can start to resolve my problem? Anyone tested
accessing Port 80 on FMS2 when a client is behind a firewall?

Thanks for the help... dave

Hi Dave,

Yes we have done it successfully. My understanding of listening on Port 80
is that you have to make your connection listen on Port 80 otherwise it will
always listen on Port 1935 which is the default.

The process i follow is first check if client is responding on 1935 if not
then try on Port 80. So you have to loop through for each port one by one.
Hope i am clear in my explanation.

So if you want to listen on Port 80 you always have to specify it in
connection string as rtmp://12.34.56.77:80/global.

Thanks
Vivek.

Hi Vivek...

But on my FCS1.5 server, I didn't have to be concerned with setting
the Port in my rtmp statement. If 1935 wasn't available, FCS simply
looked at 443 and then 80.

Are you saying with FMS2 I have to write a script that checks for
Port availability... just like the Simple Connect component?? Has the
auto port search function been eliminated?

cheers... dave

No server app can accept connections on a port it's not configured to
listen on.

Thus.. your fcs1.5 server worked on port 80 because it was listening on
port 80 (perhaps as well as the other ports, too)

FCS/FMS does not listen on port 80 by default -- it would conflict with
port 80 used by IIS or Apache etc and not start (in typical set-ups)..

Look more closely at your fcs1.5 configuration and you'll see..

But I think Dave mentioned that he has configured FMS to listen on port 80
and has unbound IIS from that IP. So that's a good start.

First of all no, you do not need to write your own connection routine to
probe different ports, the Flash Player (not FMS!) will handle this for you.
However to make the connection as fast as possible you could fire several
connection attempts on different ports at once and accept the first one that
succeeds, canceling the others out.

But the issue here may be that you believe FMS is listening on 80 when in
fact it may not be. Have you tried restarting FMS and IIS? If you do and
there is no error (both services start up fine) then your configuration
should be fine.

Also if you are modifying fms.ini then you do not need to make changes to
Adaptor.xml as well. If you are just running the defaultVhost then I'd do
this:

In fms.ini:
ADAPTOR.HOSTPORT = 12.34.56.77:1935,80,443

In Adaptor.xml:
<HostPort name="edge1" ctl_channel=":19350">${ADAPTOR.HOSTPORT}</HostPort>

This last one tells Adaptor.xml to use the value that you've set in fms.ini

Now in theory (after you restart FMS) it should be listening on 3 ports.
Which IP did you assign to IIS?

Hi Stefan...

Thanks for the direction to a new thought....

(A) When I run netstat I find:
1) my IIS IP 12.34.56.106:80 identified as LISTENING
2) my FMS2 IP 12.34.56.107:80, 12.34.56.107:443 and
12.34.56.107:1935 as LISTENING

(B) I have also restarted FMS and IIS without conflicts.

(C) An application using SimpleConnect works just fine when the
client is behind a firewall and Port 1935 is blocked.

Since you are telling me that port probing is being done with Flash
Player and not FMS2 could I be having a problem with the player?
Player 7 never gave me a problem... are there some new issues with
Player 8?

cheers... dave

I wouldn't say for sure that there are no issues with Player 8... I think I
remember that some Oss can take longer before trying the next connection.

What happens when you try and explicitly connect to FMS over port 80 from
your app?

Peldi posted this a long time ago, maybe worth running it:
