Syncthing Relay Server System V init script


prerequisites:
The provided init script relies on pipexec to keep strelaysrv running. Use

	apt install pipexec

to install it. Apart from that it uses ip (from iproute2), iptables and
logger (from bsdutils) which is available on most systems. Logging is pre-
configured to work with rsyslogd.


installation:
- install the Syncthing Relay Server: apt install syncthing-relaysrv
- copy the files from this distribution to the same locationon your system
- edit /etc/default/syncthing-relaysrv to your needs
- control and correct permissions (those script should be packaged, so this 
  is only needed when installing manually)
- link the init script:
	update-rc.d syncthing-relaysrv defaults
	insserv -v
- restart the system's logging daemon: service rsyslogd restart
- start the service: service syncthing-relaysrv start


log analysis:
Start syncthing-relaysrv in debug mode. After collecting some data you may use
    
    strelay_ctry-connections [logfile]
    
to summarize the sessions per country (a quick hack).
