[COFF] UUCP on macOS / *BSD

Does anyone have any experience with UUCP on macOS or *BSD systems that would be willing to help me figure something out? I'm working on adding a macOS X system to my micro UUCP network and running into some problems. - uuto / uucp copy files from my non-root / non-(_)uucp user to the UUCP spool. But the (demand based) ""call (pipe over SSH) is failing. - running "uucico -r1 -s <remote system name> -f" as the (_)uucp user (via sudo) works. - I'm using the pipe port type and running things over an SSH connection. - The (_)uucp user can ssh to the remote system as expected without any problems or being prompted for a password. (Service specific keys w/ forced command.) I noticed that the following files weren't set UID or GID like they are on Linux. But I don't know if that's a macOS and / or *BSD difference when compared to Linux. /usr/bin/uucp /usr/bin/uuname /usr/bin/uustat /usr/bin/uux /usr/sbin/uucico /usr/sbin/uuxqt Adding the set UID & GID bits allowed things to mostly work. Aside: Getting the contemporary macOS so that I could edit the (/usr/share/uucp/) sys & port files was a treat. I figured that it was worth inquiring if anyone had any more experience / tips / gotchas before I go bending ~> breaking things even more. Thank you. -- Grant. . . . unix || die
