# systemd unit for the LPRA host (server).
|
|
#
|
|
# The server runs as root so that the panel can open forwarded ports in ufw;
|
|
# it listens on a high local port (127.0.0.1:8091) behind nginx.
|
|
#
|
|
# Install:
|
|
# sudo mkdir -p /opt/lpra
|
|
# sudo cp bin/lpra-server /opt/lpra/
|
|
# sudo cp -r dist /opt/lpra/dist # agent binaries served at /download/
|
|
# sudo cp deploy/lpra-server.service /etc/systemd/system/
|
|
# sudo systemctl daemon-reload && sudo systemctl enable --now lpra-server
|
|
#
|
|
# Direct port forwarding (tcp/udp modes) uses port 8446 on the host — open it in
|
|
# the firewall: ufw allow 8446/tcp ; ufw allow 8446/udp
|
|
# (The "http" forward mode and terminal/files go through nginx :8445 and need
|
|
# nothing extra.) Override with LPRA_TUNNEL_ADDR, or set it empty to disable.
|
|
# The port, and the host agents dial for it, can also be changed in the panel
|
|
# settings; agents pick the new address up from the panel by themselves.
|
|
#
|
|
# ufw integration (the panel opening forwarded ports itself) needs root and a
|
|
# writable /etc/ufw and /run — see ReadWritePaths below.
