[gentoo-user] [OFF] string1!string2!string3 notation

[Claudio Roberto França Pereira]

I'm reading Writing Solid Code, by Steve Maguire, and at the end of
the book there is an about the author section that mentions two
contact addresses: one is an email, the other is
microsoft!storm!stevem. The book is from 1993, so that should be an
old address, for an old protocol. So what? That's not enough for my
curiosity. Anyone does know where this came from?

That's a bang path from UUCP.

"Bang paths of eight to ten machines (or hops) were not uncommon in
1981, and late-night dial-up UUCP links would cause week-long
transmission times. "

As others have said it's a "bang path" for UUCP routing.

It was used for mail routing even when not strictly using UUCP as well.

This was before such thing as DNS and you got to pass around host tables
(/etc/hosts) which contained all known hosts and their IP addresses.

Predates me somewhat, but I believe UUCP operated over DUN/direct
serial without the IP layer, as well.

Interesting.  That's something I wasn't aware of.

Yes, UUCP worked over both TCP and dial-up.
