Can't get Pidp1 running

[John Rayfield]

Hi all, Sorry if this is answered elsewhere. I have tried hars to find out what is wrong.

Here is the output of pdp1control start :

start panel driver, either virtual or real, depends on the symlink
starting PiDP-1 hardware front panel driver
read boot config from sense switches
switches set to 2
start pidp1 in screen
start web server
Configuring PiDP-1 for boot number 2
Ncat: Connection refused.
Ncat: Connection refused.
start usb paper tape tool

I believe it is ok to ignore the 'Ncat' errors.

In any case if i now do  pdp1control stat

I get : PiDP-1 is down.

Please could somebody give me a pointer to something to check. I am out of things that I know to try.

Thanks in advance

Ncat is a Linux utility that streams data over a network connection, network cat.

The error is almost certainly because you have some Linux firewall setting that's not allowing the port pidp1 has opened to be accessed.

Try:  sudo ufw disable

and see if that helps. If so, it's the Linux firewall. I forget which port the paper tape uses, but if the above fixes it, the ports pidp uses all need to be permanently unblocked:

udo ufw allow portnum

If that doesn't work, cd into the .../src/bliconlnlights/pdp1 directory in your install dir and do:

gdb pdp1

r

If the emulator is bombing, you should see an error message or a core dump msg.
