Re: Silly DNS question (underscore in hostname)
After refreshing my memory here: http://en.wikipedia.org/wiki/Hostname ...which references (what appear to be) the relevant RFCs, I recall that underscores are definitely not legal, but the corner cases (and instances of blatant [cough]Microsoft[cough] disregard) are interesting... ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Windows allows underscores in the hostname. Linux also allows underscores in the hostname. There is no rule that says your hostname has to be exposed to the Internet. Windows 2000 and later warn you that things will break if you use underscores, and include options to reject them entirely. Microsoft does use underscores to prefix the DNS labels for SRV records, but since *the RFC says to do that*, I think that's a good thing.

(I detest FUD, even if it's aimed at a target I also dislike.) (sigh) You're right. I could swear that just before I posted my comment I had read (parts of) a rant (with examples) about how Microsoft disregards the DNS hostname rules on the Internet, but maybe I was hallucinating - I now can't find anything like that anywhere on the WWW. Given Microsoft's history I've gotten into the habit of assuming any account of their misbehavior to be true but, of course, that isn't license to repeat crap. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
