Re: Debian upgrade breaks IRLP?

David Cameron - IRLP

A debian upgrade would not have changed the way your network routes, so something else has changed.

Do you have two routers?

You mention OpenVPN - how does it play into this? You need to have one or the other - port forwarding or VPN, not both.

Hmm.  OK.
Strange that OpenVPN works though.  The port forwards are the same, and it shouldn't have made any changes.
I'll play around with the router.

I think there is a problem with your router.  When I attempt to connect to your node on port 15425, it works, but it gives me the wrong IP address

Connected to stn7295.
Escape character is '^]'.
stn7295 - kl2zz : Welcome

That is incorrect.  It should say: Welcome

Which is my public IP.  Something is causing external connections to NAT’d to your router internal IP.

Hello all -

I've been dealing with a bit of a mystery for the past couple of days.

I run IRLP node 7295 using a 3.0 board mounted in an HP desktop, running Debian 10.  The node feeds an NHRC-7 controller, which is in turn connected to a Kenwood TKR-750.

This setup has been extremely stable.

There have been some changes over the years, with the last hardware change being in 2019 when the old computer I was using started to fail, so I switched to a new HP.

Additional software is only OpenVPN as a secondary control link so I can disable the node from my phone if need be.

I have verified my router's port forwarding with nmap from my work, and I can see the open TCP ports, and when connected to the echo reflector I can also see the open UDP ports.  My OpenVPN connection is still working as well, so I don't think there is a problem with the router or internal network.

scripts/audiotest works fine

I emulated that same test with `bin/key; play /usr/bin/soundtest.wav; bin/unkey` and that works.  I didn't really need to do that, I was just at a point where I wanted something to work the way I thought it would.  :)

So I'm confident that the IRLP node is sending audio to the NHRC-7, which is sending audio to the Kenwood, which is transmitting it.

scripts/audio_level_test also works, so I believe that the proper microphone is selected and the volume is correct.  (Which means the Kenwood should be sending audio to the NHRC-7, which is sending it to the node right?)  I get no clipping and an audio level of 69/100.

So everything SHOULD be working as far as I can tell.  I've even done a re-install of the IRLP node from backup so I should have the latest & greatest IRLP files.

But I get no audio from IRLP.  I can connect to the echo reflector and transmit to the node, but watching my router I don't see traffic other than the initial data connection.  And I don't get any hint of a reply back from the echo reflector.

Any ideas?  What am I missing?
