On-demand relays are broken in KH28, but in a way that has taken me some time to find.

It appears that the source relay redirects incoming on-demands, which is not going to work too well:

From the Relay:

[2010-12-09 12:08:30] INFO slave/open_relay_connection connecting to operations.powerfrag.fm:2112 for /pf-64k.ogg
[2010-12-09 12:08:30] INFO slave/open_relay_connection redirect received http://sinewave.powerfrag.fm:2112/pf-64k.ogg

You'll have to explain this error case in a bit more detail. Are you saying that kh28 is sending back a 302 response or that kh28 is getting a 302 response? And what is exactly wrong with those log lines?

It looks like a connection was attempted, to start a relay, it received a 302 response and tried the alternative address which failed.

That connection on the ls coming from the relay when a listener attempts to connect. The master is redirecting the relay back to itself.

I'll try to get a tcpdump sometime this weekend so there is more to go on.

I have not met with much success getting a dump on this since I'm running it on a VM with no GUI.

What is happening is that the relay (sinewave) is requesting the stream from the master (operations). Operations then redirects sinewave to itself.

Since my relay is set-up as an on-demand relay with a UN/PW to boot, it shouldn't be referenced back to itself.

Of note here is that on my master, I have max-listeners set to 0, so that clients who do connect can get referred out to any available, configured relay.

I just tried here with the latest code and it seems to be working as expected. Requests to /admin/streams should not be getting redirecting at all, only direct calls to the stream mountpoint. How have you defined the master details in the slave, <master> or the traditional <master-.....> tags?

I have not tried this with 28.5, but I will later tonight and see if that makes a difference.

I am using the new master tags:

A relay master w/ 28.5 is still redirecting my secondary Icecast to itself:

From the relay:

The times between the boxes were a bit off.

should be fixed in the kh28.9.update on my site.

This appears to be fixed in 28.9. Thanks, again!

Unless something significant comes up, I will probably rename it as kh29 in the next day or so. There is a win32 build up there now as well.
