Hi all,

I have an SBBS 3.18 release installation on Windows 10, starting as a Windows service.

Each time I attempt to SSH in to my BBS, I will receive a notification to
accept a new key, and on subsequent connections, they will fail because the
key has changed. This happens on any permutation of attempting IP or hostname
as it saves it by IP in the keystore.

I also see periodic error messages referring to keyset in my logs, across
multiple SBBS services. Not sure if it is related.

TIA for any ideas.

Sound related. What are the error messages?

Maybe this FAQ will help:

The message seen repeatedly in error.log:

No TLS certificate ERROR 'No permiss.to perform this operation' (-21) opening keyset

This seems to be added for each service that starts. I did follow the FAQ
and remove the cryptlib.key and ssl.cert files and restart all services.

I no longer see any errors in my log files, and the key looks to be stable.
I suspect it was due to changing my sysop password after installation.

Thanks for the guidance.

Cool.

That error is more likely a file permissions issue. Glad you resolved it.
