DM,

I've noticed recently that my production instance of sbbs on RPi4 that is running current latest build seems to be ignoring semaphore files to trigger services restarting. Also, if I run /sbbs/exec/sbbs interactively, the recycle command is ignored regardless of the service type that is specific.

On my x64 test system, I did a clean install of the latest build and I could recycle the services interactively and all of the semaphores seemed to work except for telnet.

What are some places I could further investigate to understand what is happening?

Thanks in advance,
-WitNik

The log output. Look for something like: "Disabling Terminal Server recycle support". This indicates that you're runing sbbs as root, with it changing to a different user-id, but you don't have the capabilities library installed. Use 'setcap' instead: http://wiki.synchro.net/howto:linux_non-root

You shouldn't need to start the BBS as 'root' then. Instead, start it as the user you intend to run it as and you can remove the User/Group settings from the [unix] section of your sbbs.ini file.

It sounds like you're running sbbs as 'root'. The entire point of using setcap (or authbind) is so you don't run sbbs as root.

Look for the [unix] section in ../ctrl/sbbs.ini and
uncomment/change the user/group definition to the user/group you
want the bbs to run as. Should be the same user as who has
file/access permissions to the directory structure.

Make sure you have the SBBSCTRL environment variable defined,
in the user environment that you'll be running the bbs as.

Start the BBS with this command (while in the /sbbs/exec
directory): sudo -E ./sbbs syslog

Done.

The BBS will now start up and be able to bind to the low ports
(because you started it with 'sudo'), but then will immediately
drop back to running as the user you defined in sbbs.ini.

Enjoy.

That was my problem. On the RPi4, I had specified the user / group setting in sbbs.ini recently. I didn't realize that was specifically for calling /sbbs/exec/sbbs from root. Once I remarked out the offending 2 lines, all was well.

Thanks,

Also, I never have called sbbs as root. I've rotated between authbind/setcap. It might help to put additional remarks in the sbbs.ini file for folks like me to not populate those fields unless calling sbbs from root.

... WARNING!! I'm naked under these clothes!!

LOL!

And, I've known people who will NOT go to the doctor, clinic,
hospital, etc., because they don't want others to see them naked!!

It's not like something they haven't seen...they've seen more
breasts, genitialia, and buttocks, than most of us will ever see,
so nudity means nothing to them. To me, they're there to save my
butt, and not kiss it. Besides, being a widower, I know "what's
under the hood", and "we're all the same from the back side".

Several years ago, with attacks of kidney stones, I had to wear
a catheter, and was having severe bladder spasms and pain, so I
had to call 911 to go to the Emergency Room.

On that cold, hard, exam table, I was naked...plus screaming and
in tears, as the pain was so bad. Two good looking female nurses
walked in, and told me "You're not going to like us"...I said "I'll
kiss you if you make the pain go away". They said "We have medicine
for the pain...but it's an oversized suppository!!".

They gave a whole new meaning to the phrase "Shove It!!", but it
did the trick.

Even further back, I had a cardiac catheritization (cardiac cath)
done, to be sure I hadn't had a heart attack. You are obviously nude
before and after the procedure, as they inject a deal into the femoral
artery in the groin area. Then, for nearly an hour afterwards, a
female nurse is holding their hands on it, so you don't bleed to
death...so, you're fully exposed there. And, you can NOT urinate
while on your back. I tried to void into the plastic urinal bottle,
but that didn't work. The nurse asked sarcastically "Did we spring
a leak??", and I growled, "No, I felt like pissing the bed".

The good news is that by going off of soda, and caffeine (mainly
green tea, as I never acquired a taste for coffee), and going to
flavored water, I haven't had any stones in awhile...and my heart
is good.
