Hi, I am installing a brand new BBS under Debian. No matter what I do, the "ExecStartPre" keeps tripping me up. I ended up trying to keep it simple and put everything in /sbbs instead of another location and did the systemctl configuration. I was getting an error about not finding the src so I changed it to /sbbs/repo/src since there is where it seems to be now:
ExecStartPre=/sbin/setcap 'cap_net_bind_service=+ep' /sbbs/repo/src/sbbs3/gcc.linux.*.exe.*/sbbs
Now when I start it, I get this:
Sep 24 09:20:15 bbs systemd[1]: Starting Synchronet BBS service...
Sep 24 09:20:15 bbs setcap[21466]: Failed to set capabilities on file `/sbbs/repo/src/sbbs3/gcc.linux.*.exe.*/sbbs' (No such file or directory)
Sep 24 09:20:15 bbs setcap[21466]: The value of the capability argument is not permitted for a file. Or the file is not a regular (non-symlink) file
Sep 24 09:20:15 bbs systemd[1]: sbbs.service: Control process exited, code=exited, status=1/FAILURE
Sep 24 09:20:15 bbs systemd[1]: sbbs.service: Failed with result 'exit-code'. Sep 24 09:20:15 bbs systemd[1]: Failed to start Synchronet BBS service.
And looking at the file, it exists:
root@bbs:/# ls -l /sbbs/repo/src/sbbs3/gcc.linux.*.exe.*/sbbs
-rwxr-xr-x 1 sbbs sbbs 114496 Sep 24 08:26 /sbbs/repo/src/sbbs3/gcc.linux.x64.exe.release/sbbs
Any ideas? Thanks

the src/sbbs3/GNUmakefile now has a "setcap" target (e.g. run "make setcap symlinks") - so you shouldn't need that in your service file.

If you want to keep in your service file, you could try removing the wildcards from the /path/to/sbbs.

Thanks, that helped and I was able to start the BBS. Now I load uedit to go and create a user, as soon as I click to add user it segfaults:

I made two suggestions. It'd be helpful to know *which* of those suggestions helped.

I'll take a look-see. In the future, it's helpful if new issues are new message threads/subjects.

Looks like uedit *really* expects you to have the SBBSCTRL environment variable set.

I removed the pre line from the service file, and that let it start ok

Just as a final note, I ended up making this change to get it to bind to lower ports:

ExecStartPre=sudo setcap 'cap_net_bind_service=+ep' /home/sbbs/sbbs/repo/src/sbbs3/gcc.linux.x64.exe.release/sbbs

The important part there is adding "repo/src". Also since I manually added the systemctl file, I think it better lives in /etc/systemd/system/sbbs.service instead of /lib/systemd/system/sbbs.service

Both of these changes might be good for http://wiki.synchro.net/howto:systemd

Thanks for the help!

I suppose, but since we have the "setcap" make target (as I stated earlier), neither of those should be necessary.
