Why Do We Name Servers the Way We Do?
jfruhlinger writes "If you use a Unix machine, it probably has a funny name. And if you work in an environment where there are multiple Unix machines, they probably have funny names that are variations on a theme. No, you're not the only one! This article explores the phenomenon, showing that even the CIA uses a whimsical server naming scheme." What are some of your best (worst?) naming schemes?
functional naming.
Machines need arbitrary names, functional names are aliases.
Use this convention for naming servers. company - airport code - role. For example, MSFT-PDX-MAIL01 (or DC01, TS01, APP01, etc)
Life is not for the lazy.
One group at JPMorgan had unix boxes named "Marx" (yes after Carl Marx) and "Bucky" (yes after Buckminster Fuller), and a slew of other Dead Utopian Philosophers.
Naturally the program that the group developed (in Visual Works Smalltalk with the Gemstone Object Database) for Trading Hybrid Derivatives is known as "Das Kapital"! Yes, it also has a start up screen with a picture of good old Carl Marx. This program trades and manages Trillions of Dollars of value (although the total value dropped recently due to, well, you know). But, was this program was likely part of the problem? Who knows? ;--)
And we name our Win boxen silly names too - every Linux or Unix or Windows box in my lab is named after a local animal (Linux or Unix) or local plant (Windows).
It's the same reason that people have nicknames for their campers and their houses ... or the CIA is named Foggy Bottom.

I remember the first computer I networked I changed so it showed up as H3110 (Hello) ... since they insisted on numbers.

The Naming of Hosts is a difficult matter,
It isn't just one of your holiday games;
You may think at first I'm as mad as a hatter
When I tell you, a host must have THREE DIFFERENT NAMES.
First of all, there's the name that the users use daily,
Such as venus, athena, and cisco, and ames,
Such as titan or sirius, hobbes or europa--
All of them sensible everyday names.
There are fancier names if you think they sound sweeter,
Some for the web pages, some for the flames:
Such as mercury, phoenix, orion, and charon--
But all of them sensible everyday names.
But I tell you, a host needs a name that's particular,
A name that's peculiar, and more dignified,
Else how can it keep its home page perpendicular,
And spread out its data, send pages world wide?
Of names of this kind, I can give you a quorum,
Like lothlorien, pothole, or kobyashi-maru,
Such as pearly-gates.vatican, or else diplomatic-
Names that never belong to more than one host.
But above and beyond there's still one name left over,
And that is the name that you never will guess;
The name that no human research can discover--
But THE NAMESERVER KNOWS, and will us'ually confess.
When you notice a client in rapt meditation,
The reason, I tell you, is always the same:
The code is engaged in a deep consultation
On the address, the address, the address of its name:
It's ineffable,
effable,
Effanineffable,
Deep and inscrutable,
singular
Name.
We never use standard names, our company deals with lots of e-payments and the idea is that the less obvious our naming scheme is, the more difficult it is for hacker to really figure out what the purpose of a server is and what it may store.
A little extra work for us, but we have ways internally of handling this issue without much headache.
See, I don't get it. WHY would you name your servers this? If you smack your head or have a hard night drinking, would you know FOR SURE that ServerX is the file server or the database server? Would you code like that? At least make the names useful.
Personally, I like MrDomainController, MrNameServer, MrFileServer, etc. Have a backup? Meet MsDomainController. Need yet another backup? JrDomainController? Need another one? No you don't. See, easy, unambiguous, useful.

My PCs are all named after Studio Ghibli heroines. I first used this with San (retroactively naming her predecessors Ichi and Ni), then with Chihiro and now with Shizuku. Both of the last two are still operating, and will be replaced with Haru and Taeko respectively. This doesn't factor much into operations, though the command line does display "rhapsody@shizuku" on this PC.
For smaller setups with less than ten machines, I like to use colours.
Red - Production Server
Orange - Staging Server
Yellow - Test Server
Green - Dev Server
Blue/Purple/etc etc for other things like the database server etc.
This way, when I'm setting up PuTTY or another shell, I can set the foreground text colour for each machine to match the server name, which stops most of those embarrassing mistakes when you run a command on production that you meant to run on test, and so on.
In Halifax some years ago a larger University took over a smaller but much better Engineering school called TUNS. The takeover was quite hostile with Dalhousie doing a "My way or the Highway" routine in all areas. The computer system set up by Dalhousie for TUNS was called borg. Never has a better name been given to a server.
Well I think the reason for having a bunch of "Cute" names for the server is just really prevent confusion.
Oh Crap Medusa is down. vs. WebServer014 is down. We tend to relate better with recognizable names, so it creates a spot in the persons memory of all the systems, vs boring names where they will just become mixed in the fray.
In college over a decade ago, we had Greek Mythogy Names. And I still know what system is which by the name.
Morpheous and Ultra Sparc was the main file/web server
Zeus a 2 CPU ultra Sparc e250 was the remotelogin ssh/telnet server where the CS students did their work.
Then we had Valhalla and Pandora the Ultra Sparc 1 workstations...
It is actually quite effective memory tool. for the NT workstations we just had NT1 NT2.... I can't remember what order they were in or which one was different then the other.
Those names actually made administration much easier.
If something is so important that you feel the need to post it on the internet... It probably isn't that important.
People name computers because it makes good sense. Although computers don't have self-awareness and thus intrinsic personalities, they are subject to the natural tendency for people to project personalities on them based on behavior and appearance. People who don't project personality onto other objects and people probably have a personality disorders themselves, like Asperger's syndrome. But the projection of personality by humans is a mnemonic that aides in remembering a particular blend of traits of a person (or other object) and is thus a practical habit. People name a machine to make a slot in their memory for its personality and then fill in that slot as they learn about their machine. In this sense, systematic names like server01, server02, server03, etc., are not unique enough to be helpful because they can not easily be differentiated by the normal person.
Just callin' it like I see it.
This is why my mail server is 192.168.1.25 and the web server is 192.168.1.80, etc. Dev web server is 192.168.1.81. At least you can guess by the IP what it's about, based on that scheme.
Oh and their names?
Moiraine
Berelain
etc...
