Graffiti Wall for BPQ

---

MIT License

NodeWall is a Graffiti Wall for Packet Radio. It's made to work with the BPQ32 Packet Switch from G8BPQ. It requires that you have a basic Python3 install which most everyone should who runs modern Linux.

NodeWall when running on your packet system will look like this:

*** Connected to WALL

Installation

Download and install NodeWall to your system:

git clone https://github.com/juniberry/NodeWall.git

Configure BPQ to connect to external application ports¹:

; Telnet Port
PORT
PORTNUM=15
 ID=Telnet
 DRIVER=TELNET
 ; ... etc ...
 CONFIG
  ; external application ports, zero indexed!
  CMDPORT=6000 6001 6002 6003 6004 6005 6006 6007 6008 6009 6010
ENDPORT

; Application Lines
APPLICATION 1,BBS,,N0CALL-1,CALBBS,255
APPLICATION 3,CHAT,,N0CALL-11,CALCHT,255

; External Applications
APPLICATION 10,WALL,C 15 HOST 1 S,N0CALL-14,CALWAL,255

Note: CMDPORT= ports are zero indexed, such that "C 15 HOST 1 S" will connect to port 15 (Telnet) in the example config, and then connect to local host on command port 1 which is the second port 6001 in the CMDPORT= list. The "S" in the connect string tells BPQ to return the user to the node when they exit NodeWall.

inetd server

You can run NodeWall from inet.d or xinet.d as a TCP service²:

service wall
{
	disable		= no
	protocol	= tcp
	port		= 6001
	server		= /home/bpquser/wall.py
	user		= bpquser
	socket_type	= stream
	wait		= no
}

systemd server

You can also run NodeWall from systemd as a socket service³:

/etc/systemd/system/wall.socket

[Unit]
Description=LinBPQ Wall

[Socket]
ListenStream=6001
Accept=yes

[Install]
WantedBy=sockets.target

/etc/systemd/system/wall@.service

[Unit]
Description=LinBPQ Wall Server

[Service]
ExecStart=/home/bpquser/wall.py
StandardInput=socket
User=bpquser
Group=bpquser

Then enable the service

sudo systemctl enable wall.socket
