Can anyone define what constitutes a legal uucp hostname? As it says in my sig., I have something to do with the VMS implementation of uucp that's available through DECUS. A neighbor of one of our sites recently decided that, since their Internet domain name (call it foo.bar), period and all, was just seven characters long, they'd use that for their uucp hostname too! (Yes, they were sending \020Shere=foo.bar\000) Naturally, this broke all kinds of filename-generating assumptions in our code. VMS can't tolerate more than one period in a file name. Sure enough, I can't find anything written anywhere that prohibits periods in uucp hostnames, though it certainly isn't common. Hyphens I see all the time (and we can handle easily), but periods? This particular site has changed their mind and is now just using "foo" for their uucp name, so the immediate problem has gone away. But for the future... We can roll with this particular punch via filename translation -- we're doing some of that already, it's not much trouble to extend it to allow for this. But before we commit to the design for the next release, I'd like to know: Just what else can appear in a hostname? What maximum length? And so on. --- Jamie Hanrahan, Simpact Associates, San Diego CA Chair, VMSnet [DECUS uucp] and Internals Working Groups, DECUS VAX Systems SIG Internet: jeh@simpact.com, or if that fails, jeh@crash.cts.com Uucp: ...{crash,scubed,decwrl}!simpact!jeh
