Howto install manually Syncthing in a NAS DNS-320 (with funplug 0.5)

I have found a solution with this /ffp/start/syncthing.sh:

#!/ffp/bin/sh

#PROVIDE: syncthing

#REQUIRE: LOGIN

. /ffp/etc/ffp.subr

name="syncthing"

command="/ffp/bin/$name"

required_files="/ffp/var/syncthing/config.xml"

syncthing_flags="-home=/ffp/var/syncthing"

run_rc_command "$1"

With a copy of the Syncthing database in /ffp/var/

Syncthing launches correctly, but then I cannot be any more connected with Putty or Filezilla (refused connection), and the other process (Mediatomb) don’t launch at startup !
