Yes, I just send kiss encapsulated packets.

I got the DV Switch installed an working with my phone. pretty neat stuff.

I run 4 raspberry pi's with dmr brandmiester, tgif, d-star an wires-x

To BPQ users that lost a link with K5DAT-7, my node.

I apologize for that - I have moved, and the Internet access is wireless based with no port forwarding.? Therefore I can no longer support AXUDP links. Furthermore my amprnet links were lost as well, and it appears I can no longer support those also.

As mentioned in another thread, AXTCP works, and the map below will work for K5DAT-7 if you forward TCP port 10200 from your router to BPQ.

MAP K5DAT-7 0.0.0.0 TCP-Slave 10200 B

If you would prefer to use a different port, feel free to email me privately, and I can set it up.? TCP 10093 may not be a bad choice, especially if your router is already forwarding both TCP and UDP 10093.

Thanks.

Just made the change

MAP K5DAT-7 0.0.0.0 TCP-Slave 10200 B

Hi Paula,

I am not using Xrouter here but do have several active BPQ AXTCP links where my end is the slave. Outside of my own lab testing I have not had an opportunity to test an external AXTCP link with my end being the master but was intrigued to try given the info you provided. Initial testing shows an exchange of traffic but no BPQ link is established.

Tcpdump on the BPQ system here shows:

09:51:03.600102 IP 192.168.1.139.33155 > brom-11-b2-v4wan-165874-cust330.vm31.cable.virginm.net.9393: Flags [S], seq 3045083897, win 64240, options [mss 1460,sackOK,TS val 1072902549 ecr 0,nop,wscale 7], length 0
09:51:03.718534 IP brom-11-b2-v4wan-165874-cust330.vm31.cable.virginm.net.9393 > 192.168.1.139.33155: Flags [R.], seq 0, ack 3045083898, win 0, length 0

And on my router shows:

13:51:03.596673 IP c-73-165-23-36.hsd1.pa.comcast.net.33155 > brom-11-b2-v4wan-165874-cust330.vm31.cable.virginm.net.9393: Flags [S], seq 3045083897, win 64240, options [mss 1460,sackOK,TS val 1072902549 ecr 0,nop,wscale 7], length 0
13:51:03.712663 IP brom-11-b2-v4wan-165874-cust330.vm31.cable.virginm.net.9393 > c-73-165-23-36.hsd1.pa.comcast.net.33155: Flags [R.], seq 0, ack 3045083898, win 0, length 0

So we are exchanging packets but BPQ so far does not like something...

Hi Lee,

In case you (or anyone else :-) are interested, my XRPi node G8PZT:KIDDER in
the middle of England has an open AXTCP server on "g8pzt.noip.me" port 9393.

It has been in use for many years with Xrouter clients, but as far as I know
never with BPQ.

So if you want to try it, I'd be interested to know how you get on.

Subject: [bpq32] AXTCP Links

Hello to those on the list. I've just moved to new rural location, and it
appears my wireless based internet service does not pass any unsolicited
communication from the Internet to me. Even though I am using my own
router, the port forwarding and ampr-ripd configurations are moot.
Therefore I have no AXUDP using 10093, etc. and no ampret.

Anyone interested in restoring their link with K5DAT-7 can use AXTCP with
their side as the slave. In that case the map for K5DAT-7 would use this
format if port 10200 were used:

MAP K5DAT-7 0.0.0.0 TCP-Save 10200 B

Each AXTCP link must use a unique TCP port, and the slave side, i.e. your
side, must forward the TCP port in the local router to the BPQ host. Feel
free to email me directly to work things out. If there are further
questions in general about AXTCP, feel free to ask them on list.

Unfortunately I don't have a solution for JNOS and URONODE currently. As I
recall XRouter supports AXTCP, so it may be a solution there. When I get
some time I may try an AXTCP link across the LAN between BPQ and XRouter..

Hi Paula
I was also curious! - does not appear to work, I get an error message from BPQ and this is a packet trace:

If you want to host more than one TCP-Slave links they must use different ports, but a TCP-Master can connect to more than one site using the one port.

Hi Lee

Can you do an experiment to see if you can use 10200 outbound to my two nodes and see if they work. It is my limited understanding that when traversing NAT, the source port exiting the NAT is randomised, the destination is of course not. Theoretically unless BPQ is doing something unexpected, the two outbound links you make to two different designations on the same port would be treated as independent of each other.? Good experiment to try, but if you do try it make sure there’s traffic going through both at the same time.

If this works it could help simplify TCP-Slave setup for others.

It’s 100% certain the destination host must have a unique port open just for your link on their end. 10200 was the actual upper end of my range I had open for TCP links on -7, I’ve increased that to 10300 for the future.?

Great catch. I can use the same port to your -7? and -5. Both links are up. That does indeed simplify using AXTCP.? The map I posted can be used by multiple stations - contrary to what I said earlier.?

Nice one Lee, thanks for confirming- gonna write this down/up somewhere!?
Would love to see some pics of your new place in rural area, sounds like a nice move despite the internet situation, lots of greenery I hope :-)

Thanks Red, yes, the keyboard on the laptop is getting worn out - a symptom of inheriting it from my wife.? I have a few links up now with others thus proving it works. :-)

I assume from your response that you used port 10200 (repeating the map below without the typo).

?

MAP K5DAT-7 0.0.0.0 TCP-Slave 10200 B

For clarification, no one else can use that port to connect to K5DAT-7 now that I'm using it for a link to Red.

Ping me via email pe1rrr at amsat dot org to catch my attention as quick as possible to set another port in case it doesn’t work.

Hi Lee

Same situation for YD0BCX which is the solution I implemented for him in Indonesia.

Dang typo monster ate your map line - for anyone reading its: TCP-Slave.

I have updated your maps on both my nodes (not sure if you had a link to -5 as its an auto udp-map node)

Hi Lee - I had a similar experience when I switched to a wireless internet provider.? I found a simple way to tunnel through my ISP's CGNAT network architecture and it works very well with BPQ.? ??is a service that will permit you to expose up to 10 ports from your local host in your choice of protocols - TCP, UDP, HTTP, or TLS.? The cost is $5 per month for ten ports.? The service runs in PowerShell without a GUI so it is very light on resource use.? I run it on a Windows 10 machine and I do not know about options for other platforms.? I'll be glad to post my PowerShell scripts if others are interested.

BPQ has a very simple file server that doesn’t support directories, ?for me I use FBB V7.0.11 found on sourceforge, for Linux. It has an advanced file system for uploading and downloading as well as supporting private dirs.

The only drawback is it is funky to set up. It requires a DED TNC emulator to be configured in BPQ and FBB to use the DED interface to link into the node. It works great.?

Log into PE1RRR-3 if you can, and hit ‘d’ for DOS. See if thats something you like.
