Alas:
Here is the service file for the tcp client at the RTKBase box.
Does not use any of Stefal’s own code nor is it controlled or configured by it.
Just the rtklib str2str as installed by RTKBase.

At the public server, I installed from Stefal’s RTKBase
- rtklib executables (ntrip-caster capable)
- a modified service file for the caster
- a modified config
- a modfied start wraper aka
run_cast.sh
Before, I tried a direct call to str2str in the service file as well.
However, the parameters for a caster that go to the command line are quite clumsy, so I gave up reinventing the wheel.
The service file:
~$ cat /etc/systemd/system/str2str_ntrip_caster_realy.service
[Unit]

In the config, I just changed the credentials and mountpoint.
In the wrapper, It boils down to one line for some in_tcpsvr-configuration, which is not part of Stefal’s code, and a debug to log the str2str command line.
...:~/test/RTKBase_part$ diff run_cast.sh.000 run_cast.sh

I know that @Stefal is not in favour of private casters.
But may be that some users might be happy to find this in RTKBase, nevertheless.
Will drop him a note.
