It doesn't seem this way from my reading of the source code:

upslogx(LOG_ERR, "[%s] %s: Error in packet: %s",

 From what I can tell, that's a regular log message of an error, not a 
debug mode message, which would use either "upsdebugx" or "debug", or 
a warning, which would use upslogx with "LOG_WARNING".

In addition, the errors are continually output to syslog; they don't 
just appear once and stop.

Perhaps you could change LOG_ERR to  LOG_WARNING and perhaps you can 
ignore it after the first time it appears.

My nut configuration is fine. To troubleshoot this, I had to label 
each one of ACCESS-DENIED errors in the code, and with that, I 
determined that the one involving tcp-wrappers was complaining. It 
appears that local network communication is hard coded with In my /etc/hosts.allow, I just have "ALL:localhost", with 
no TCP wrappers doesn't know or check that they're the 
same, so I once I added it, it started working. :-) Presumably, 
previous versions used localhost.
