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...

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..

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 - 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.

Re: Advanced file storage and transfer with BPQ
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.?

Greg, the PHP stuff is awesome for fetching data and generating stuff as you said, great flexibility. I¡¯m pleased you¡¯ve found it worthwhile.? A nicely formatted page with hyperlinks to different sections of your station apparatus to drill down into the cheatsheet has real potential. The menus are literally only html lists, setting the ¡®f¡¯ mode first will make a page appear all in one go with original formatting, by default it pages it condensed without empty lines (a side effect of the method to generate pagination), bonus mode for slow links. Best of luck and happy experimenting! 73 Red

Advanced file storage and transfer with BPQ
Hey everyone,? One of the services we would like to offer is file storage and transfer. We would like the ability to upload files locally and via RF, organize those files in folders, and give users access to a readable, searchable database they can upload and download to/from.?
Our BPQ node is running inside a win10 virtual machine hosted on a Ubuntu host.??
Any ideas? What's everyone using?

Good Morning,
Not even sure how to begin with a thought I have on my current BPQ32
implementation. I am new to BPQ and picked up the torch for our area, an older
Ham was running our RMS gateway on 2m packet and had an equipment failure (was
running BPQ), he is wanting to slow down on some items so I took up the RMS
gateway (Had to rebuild from scratch) and have added BPQChat, BBS Relay for
RMS, I am about to implement VARA HF (Have the configs done/tested), and I have
one last item (Below) I want to sort if possible. Being an ARES member and the
only station in our area with a 24/7 Battery/Solar station it made sense for me
to pick it up the gateway as an EmComm resource... I hope its never needed as
such, but its ready, tested, and available. My Qth also makes it prime along
with the station towers (crank downs to get it out of the weather when it hits
and quickly back up) and location since it is reachable by almost all the
surrounding areas.
The last item I want to attempt is an additional application on the node, but I
do NOT want to put this within the BBS information, most connections are not
going to bother digging into the BBS. The Application (and SSID associated to
it) would simply dump a text file to the connected station. In the case of a
connection to the SSID directly (e.g., N3BYR-3), it would connect, dump the
text file to the station, and disconnect. In the case of application selection
from the primary node (in this case N3BYR-7), if the user selected by typing
the option "NodeDoc" like they would with CHAT or BBS or CMS, it
would run that application line to drop the text, and return to node (STAY) if
the S option was used.
The drive behind the idea of having a Text file that BPQ can essentially dump
to a connecting station, is having a quick way to pull a few items I plan to
list on the text file. These would include important ARES stations to reach,
any upcoming nets or exercises on recurring basis, associated frequency lists
for the area, and a weather report/condition (I'd write my own code to pull WX
data and add into the text doc at intervals). I think having this would be good
for quick glance information, and more "Up Front available" to the
local area packet stations instead of digging into the BBS looking for a
bulletin or message.
Is there already a method in BPQ to do this, or has someone else done this?
Most the other settings in BPQ are easy to google and configure, not even sure
where to start with querying google or the BPQ site to approach this... thanks
ahead of time!
Greg - N3BYR

John, did anything ever come of this?? I came here by way of googling if BPQ32 could talk directly to a 6PACK prommed TNC.
I have a stack of TAPR TNC2 clones that was given to me a long time ago.? I bought a EPROM burner and having a blast sandboxing with flexnet and linux.? The 6PACK prom works great when just doing plain AX.25 connects to my BPQ node but get FRMR with NETROM streams.? I am thinking that the 6PACK driver maybe trying to setup a flexnet link or something.? I am just dabbling, and the documentation is sparse.? So it is configuration by trial and error.

Re: Node Announcement Text File?
Good Morning Red,
???? I will take a look at the update on git and make notes when time permits today. After I walked away I thought of the webserv that BPQ is utilizing and had the same thought about compliance... plus it was not really meant to handle this aspect anyway, it may be the root of the issues in general also. I'm unfamiliar with lighttpd but I'll look over it and consider an install, I am more familiar with apache and nginx - so there are options available, I'll update you on the choice and outcome for reference. I am not using the proxy at the moment on the test case but will place some serious restrictions on the Pi for web browsing through some firewall settings and some other controls. Its not really a concern of what/where someone decides to surf - but more of a concern of limiting resources on the system and ensuring those resources are focused on needs.
???? The log is from the system, I did install the openbsd-inetd. I only pulled what was in front of me at the time. I'm unsure though which PiOS you may have put your test case on for the original creation, I'm running Bulleye and the image was initially created about 2 weeks ago. After burning an image and setting up BPQ, I created a backup image - which I used again on the test platform. Hopefully the above and this post are relevant to helping you develop the script, your time is appreciated. I'll give more feedback later today or as soon as I am able to make some changes.
