- Connected via USB (actually, a USB to serial converter internally)
- Run newport emulator: sudo python3 picoserver.py (need sudo rights to bind to telnet port 23)
Find the USB terminal:
find /sys/bus/usb/devices/usb*/ -name dev (idea taken from: https://unix.stackexchange.com/questions/144029/command-to-determine-ports-of-a-device-like-dev-ttyusb0)
Check status of UFW (firewall):
sudo ufw status verbose
- ssh: port 22, should be "ALLOW IN"
- telnet: "sudo ufw allow 23": opens telnet access
Allow access to USB terminal:
sudo usermod -a -G dialout e320
