If I create a macro with a line such as:
RN /home/scott/relay.sh 5!
... as which user will that command run?
I have just built a new Rivendell machine that uses such a shell command
to fire a relay on a USB relay box that appears as /dev/ttyUSB0.
The comand works flawlessly... if I run it manually from a command line.
Rivendell, however, executes the shell script, but the script won't talk
to the box unless I chmod o+w /dev/ttyUSB0 . I don't want to do that; I'd
rather add the user in question to the dialout group, if I can figure out
what user it is.
Rivendell is running as the user 'scott'. 'scott' is already a member of
the dialout group; therefore, the command must be executing as some other
user, but which one?
This is RD version 2.15.3 running on Debian 8.
The box is a KMTronic Ltd. Model U8CR. I've used them before on Rivendell
systems and have not had this problem. In the past, adding 'scott' to the
dialout group always got the box working. I wonder what's changed.
