Re: [pulseaudio-discuss] How to redirect pulse audio through ssh?
Hi, From what Colin says, the standard port is 4713 for pulseaudio. As I said before all network ports are blocked except port 22 which is only for ssh connections. I should be able to tunnel port 4713 through ssh by doing this: ssh -L 4713:localhost:4713 user@server. Then I can tell pulseaudio to use the servers local port 4713 which is automatically forwarded to the client's local port 4713. But from what pactl stat command is telling me, then port 4713 on the client side seems to be blocked as it is giving a connection refused. I know the tunnelling works with ssh because I use vnc connections through ssh by ssh -L 5901:localhost:5901 user@server and that works perfectly with my vnc client and server solution. I am not sure if I can use pactl load-module module-protocol-native-tcp together with tunnelled tcp connections. I need more details on how to that. btw, I can see there is something listening on port 4713 on the client when I use the netstat -an|grep 4713 command: - tcp0 0 0.0.0.0:47130.0.0.0:* LISTEN - So now the question is why does the listener process on the client not accept pulseaudio data via the ssh tunnel? br, Quinn On Fri, May 20, 2011 at 7:15 PM, Fred Frigerio ffrige...@frigerio.uswrote: Have you tried redirecting the port in SSH?

I am bit unclear on what the correct way is of doing it. Firstly, I wrote up how our X11 piggy backing stuff work here: http://colin.guthr.ie/2009/08/sound-on-linux-is-confusing-defuzzing-part-2-pulseaudio/ Technically we do not tunnel over SSH directly (this can of course be done, but not automatically as SSH does not know about PA in the same way it knows about X11). We can however piggy back on the X11 forwarding built into SSH for our authentication (cookie) and server connection strings. If this is on a private network (direct routing) then the built in way is the best, but it doesn't go over SSH. You just need to ensure the machine you're sshing from has the netwrok protocol
Re: [pulseaudio-discuss] How to redirect pulse audio through ssh?
Hi,
I found this message when I am trying to tunnel 4713 via ssh ssh -L
4713:localhost:4713 user@server:
bind: Address already in use
channel_setup_fwd_listener: cannot listen to port: 4713
Could not request local forwarding.
BUT, this seems to work ssh -R 4713:localhost:4713 user@server (notice the
-R parameter)
So, it seems the forwarding direction has some say in this. Forwarding from
local to remote is not the right way, but forwarding from remote to local is
the correct way.
pactl stat also seems to get a bit futher this time with the correct
tunnelling direction:
-
Using shared memory pool with 1024 slots of size 64.0 KiB each, total size
is 64.0 MiB, maximum usable slot size is 65472
Trying to connect to localhost:4713...
SHM possible: yes
Protocol version: remote 16, local 16
Negotiated SHM: no
Connection failure: Connection terminated
-
So now we are down from connection refused to connection failure:
connection terminated.
If I attach an strace to the pulseaudio process then this happens when
pactl stat tries to connect to it remotely:

Re: [pulseaudio-discuss] How to redirect pulse audio through ssh?
Hi, I think you're maybe getting a little confused by client and server in terms of how things work here (perhaps not, as I've not thoroughly read all the many posts in this thread). As I know how to do what you want to do, I'll just write the instructions here: 1. Start of on the machine you want to hear the sound on. This will be your local terminal. It's the server in this case as it's running the PulseAudio server. You do not need to run a PulseAudio server on the other machine, just use the PulseAudio client library for audio (either directly or via alsa-pulse plugin). 2. Open a terminal and type: xprop -root | grep PULSE_COOKIE Ensure this has some output. If it does not then chances are the start-pulseaudio-x11 script was not run at login (or you have restarted your PA server after logging in). Try just running start-pulseaudio-x11 and see if that fixes it. 3. Ensure that the tcp native protocol module is loaded. pacmd list-modules | grep module-native-protocol-tcp If it is not loaded, then simply type: pactl load-module module-native-protocol-tcp 4. SSH to your other machine: ssh -X -R4713:localhost:4713 OTHERMACHINE If you get a warning: Warning: remote port forwarding failed for listen port 4713 then chances are there is a PA daemon running there already, or you've SSH'ed twice. If the former, just change the *first* instance of 4713 to a random number of your choice (1024). 5. On this remote machine, check your cookie is available via the xprop command show in step 2. If X11 forwarding is working properly, it should show up fine. 6. Set the PULSE_SERVER variable to the forwarded tunnel port. export PULSE_SERVER=localhost:4713 (or the port number you picked in step 4 if different) 7. Confirm it's all working: PULSE_LOG=99 pactl stat Done!! So in this setup, the cookie used for authentication is forwarded automatically via piggy backing on to X11 connections but as you cannot connect directly to the machine we've had to override the PULSE_SERVER variable to go over the SSH tunnel. Below is the output from my session where I run these exact commands (note the host name in the pactl stat at the end).
