FYI
Here is a service startup script for Conquest running on Fedora 16 which uses systemctl (systemd) as its service manager.
Code
copy and paste this into the file conquest-pacs.service changing the directory paths to where your dgate executable is.
copy the file into /lib/systemd/system
execute
$ systemctl daemon-reload
$ systemctl enable conquest-pacs.service
to start dgate execute
$ systemctl start conquest-pacs.service
to stop
$ systemctl stop conquest-pacs.service
to restart
$systemctl restart conquest-pacs.service
to check status
$ systemctl status conquest-pacs.service
Cheers
