Error when starting RTMPSUCK on Ubuntu 10.4 LTS: Failed to start RTMP server, exiting

[mcpogue]

Hello, I get the following error when attempting to start rtmpsuck:

ERROR: startStreaming, TCP bind failed for port number: 1935
ERROR: Failed to start RTMP server, exiting!

compiled from latest source 2.2e
created user rtmpsuck
redirected output with the following line:

iptables -t nat -A OUTPUT -p tcp --dport 1935 -m owner \! --uid-owner rtmpsuck -j REDIRECT
su to rtpmsuck

ran the server with -z option for debug output
got the error above

Ubuntu does not have a su account; as installed you can only sudo from your user account.

Create a su account to fix your problem. see http://stream-recorder.com/forum/ins...html#post17938

I did as you said, same error...what am I doing wrong? even ran rtmpsuck with root privileges and did not work. Help?

This is how i go about using rtmpdump in ubuntu and it works for me in versions 9.04-10.04 of ubuntu.

1. Download the latest svn version.
2. Make sure you have all the dependencies
3. Compile (the latest svn version 2.2e now can be installed system wide)
4. Create a new user account so i can monitor the rtmp protocol
   System->Administration->Users and Groups.
   Create a new user/login account name it whatever you want.
5. Before getting the stream running within your browser setup your monitor rules and launch rtmpsrv.Open the terminal
   

   sudo iptables -t nat -A OUTPUT -p tcp --dport 1935 -m owner  \! --uid-owner user2  -j REDIRECT

   replace user2 with whatever name you have named the user account you created.
6. Next switch to that account within the terminal
   

   sudo su user2

7. Next launch either rtmpsrv or rtmpsuck (if you use rtmpsuck make sure the folder you are going to save the file to is shared between your user accounts otherwise nothing will be downloaded/saved)
   

    rtmpsrv

8. Now visit the site that has the stream or start playing the stream, rtmpsrv will generate the syntax needed to download using rtmpdump or if its rtmpsuck it will begin saving (ONLY if the folder you are currently in is shared) if you use rtmpsrv then you need to copy the syntax and return to your default user account
   

   exit

   Dont close the terminal yet you need to cancel the monitoring rule as well as download using rtmpdump
   

   sudo iptables -t nat -F

   rtmpdump "syntax" -o Save.flv

   replace "syntax" with what you got from rtmpsrv and "-o Save.flv" is if you want to save the file under a different name and somewhere else, and thats it.

Have now compiled this software on both fedora 13 and ubuntu 10.4 LTS using the command "make SYS=posix". I have OpenSSL 10.0.0a installed as well as zlib 1.2.5 all three compled without errors.

Have followed all instructions to the letter, I don't think the problem is the proxy itself.

According to the error, something is preventing the proxy from binding to it's port, ergo the proxy aborts and exits, what could cause this?

Cant see what the problem is myself.
Did you flush the previous monitoring rules?
With

sudo iptables -t nat -F

Thats the only reason for that error i can see, try updating to the latest svn version of rtmpdump

I downloaded rtmpdump 2.2e and followed the instructions. When I launch rtmpsuck

./rtmpsuck

it starts without any problem.

But when I launch rtmpsrv

./rtmpsrv

I get the same error:

ERROR: startStreaming, TCP bind failed for port number: 1935
ERROR: Failed to start RTMP server, exiting!

Tried

sudo iptables -t nat -F

to no avail.

I use Ubuntu 10.04 Lucid Lynx.

This probably happens because you can't use both rtmpsrv and rtmpsuck, but may be I'm wrong.

Only one program can listen on a TCP port at a time. If you started rtmpsuck then you have to stop it before you can run rtmpsrv.
