telnet localhost 4444

I don't know when it stopped working, but I must have made a change somewhere... ugh

Under AXCall there is an option to connect via telnet localhost 4444

It attempts 192.168.1.15:7685 which is the correct ip and port. It has worked many times.

I now get a browser error Hmmm… can't reach this page

192.168.1.15 refused to connect.

Any ideas where to look?

Until I sort this out or reinstall DigiPi image and start over... Is there possibly another way to connect to the localhost to connect to my bbs? I can get to shell.

I still can't sort out how to resolve the error that is preventing me to connect to the localhost telnet port. This is the AXCALL feature to connect to localhost. See error in this thread.

Is it on my windows side by chance in the firewall or possibly a change I made to my digipi install?

I think I'll reinstall the image when Craig comes up with a newer version, but it that will be a while it might continue to drive me nuts that it isn't working.

Hi David,

Did you make any changes to digipi under the hood? update/upgrades? (don't)

The file in question is /var/www/html/axcall.php. it runs ttyd which runs "telnet localhost 4444".

Firewall/OS not allowing access to digipi on 7685? MacOS does this by default.

Can you click "Shell" and get a prompt? then type "telnet localhost 4444" ? You can
ssh/putty into digipi also, and also run telnet.

This is how it works behind the scenes,

netstat -npvat | grep 444
tcp6 0 0 :::4444 :::* LISTEN 782/xinetd

cat /etc/xinetd.d/ax25-node
service ax25-node
{
disable = no
socket_type = stream
protocol = tcp
port = 4444
wait = no
user = root
server = /usr/sbin/uronode
}

if it helps,
-craig

Craig,

Yes I can access telnet localhost 4444 from SHELL. This at least allows me to log on locally.

Note: I will fix this with a full rebuild when you release the next version so I'm only posting this as information and no real need to resolve. I'm in no hurry and appreciate all that you are doing on this project. I'm having fun and learning.

I do, however, remember now when this happened. I was borrowing a friends DigiPi to test and see if NET/ROM was working when connected within RF to each other. We currently don't have any other stations close enough to hear each other and have been routing via a nearby Winlink Server repeater. Therefore NET/ROM wasn't apparent.

I put the second DigiPi on my network and I wasn't able to access either via a browser (http://DIGIPI.local) since the two conflicted. I could use the IP of each device. One was 192.168.1.15 and the other 192.168.149. Then oddly enough they switched ip addresses at some point in the testing, not sure why or how but it might be an important detail.

During testing and both on the local network AXCall feature localhost stopped working.

When I gave the borrowed DigiPi back and took it off my network the AXCall feature for localhost still didn't work. I rebooted the router, hoping it would release ip addresses and clear routing tables. I can now use DIGIPI.local in my browser, but AXCall localhose is still not working.

xinetd responds to hits on port 444, it's not listening on your DigiPi . did you change
the hostname of your digipi? i wonder if xinetd doesn't like that.

We're getting closer. Is "AX25 Linux Node" turned on and functioning with radio attached? that's required,
otherwise uronode will bail if it doesn't see an ax0 network interface, refuse to connect.

We can ask syslog to show us what xinetd loaded, we can see here ax25-node is loaded,

Radio is attached and AX25 Linux Node is set to auto start.

I can connect to my node from another radio and access the Welcome to the digipi packet shell.
