The manual seems to allow the under score, but the error message from 6.8.1 seems to allow only the dash. And this is new behavior since 6.8.1
What's up????
Though the manual and other implementations allowed it, the underlying standard has always forbidden the use of underscore in host names. https://en.wikipedia.org/wiki/Hostname#Restrictions_on_valid_hostnames

Great. Good to know. I guess we should all try to be compliant with RFCs. I don't recall seeing anything about this in the release notes for 6.8.1, and I don't know where the 6.8.0 notes are. In any rate nothing on my LAN vomits over it, but I will when I get a chance go through my LAN and change the host name and fix all the links... URGH!
Thanks for your reply.
