I'd like to be able to change the ip adress of the gearman

from localhost, to the actual ipaddress of the machine. This of course
involves changing the port forwarding from the client to the server
machine.
Thoughts/Comments would be useful
simple with a systemd-unit which also survives a reboot of the target machine
because the command in ExecStart (which is *one* line inclduing the port
22 of the forwarded service, in this case SSH of a internal machine)
will fail in that case and the SSH command is executed 60 seconds later
/etc/sysconfig/forwarding contains the IP-address where the forwarding
should listen instead 127.0.0.1, done this way because there is a fallback
machine, more than one such services and so the systemd-units can be re-used
the result in short is 192.168.0.35:11025 is the forwarded 192.168.1.15:22
192.168.0.0/24 is a different subnet than 192.168.1.0/24, the numbers are
generic to not disclose network-configurations, the files below are
from a live-machine in all other parts
