David, you got me. I put those lines in years ago (on some person's
recommendation), while I was still running pre-Debian 4 (probably Redhat in
the box days).

It works and that's all I can say.

Best,

Not my first line, thats from someone elses reply.
Actually, the domain name here is sick bird out on the net, but to linux 
its just a unique text string. I have known some of the smarter animals 
we share this planet with, and have witnessed horses that had been to 
school, and watching one of them work one Sunday morning certainly was 
an education. He knew what his job was with or without a saddle warmer 
on board, and he understood his job was easier as a 900 lb quarterhorse 
without 235 lbs of Bobby in the saddle, so the rest of the morning all 
Bobby had to do was look at a calf that needed branded and vaccinated 
(my job was running the black leg sringe) and that horse would go get 
that calf and run it into Bobby's waiting loop for the takedown. And 
I've met a sorta tame coyote that was easily the smartest looks like a 
dog, critter ever. Lady was picky who she was friends with, but she  
could also do simple math by barking the number of the answer times.

So my local domainname is coyote.den. Sometimes its unreal how you 
remember such details 40+ years later. Lets just say its been quite a 
ride the last 80 some years.

I don't believe in crossing fingers either  FWIW, I pick my nose
instead, and I think it works just as well (but be careful not to do
that right after chopping some habanero),

Puts me in mind of an anecdote one of my uncles told me, regarding himself.

We're all probably familiar with the little crusty bits that sometimes
have to be wiped out of the eyes after waking up in the morning. (From
what I can tell, these seem to happen more frequently after increased
consumption of sodium or the like.)

An uncle of mine once told me that he used to have to do that on a
regular basis, but then at some point in his life he put a drop of *hot
sauce* into each eye as one does with eyedrops (from what I gather,
apparently intentionally) - and although that was astoundingly painful,
he's never had those little crusty bits again.

I have never dared, nor even seriously had the impulse, to try that
experiment for myself. As to whether it has any basis in empirical fact,
your guess is as good as mine.

It may be your "standard", but it isn't what the installer gave you.
Is there a good reason for changing it?

> Why should it have the 2nd one?

Your machine hasn't any static external IP address. The system hostname
has to resolve to something and is assigned 127.0.1.1.

No good reason advanced.

For those users who read this far: ignore this advice; it is
something the OP is programmed to do without putting any
thought or investigation into the matter and isn't of any use.
Stick with what the installer gives you.

Changing the hostname on a Debian system is a good way to gain an 
appreciation for DRY:

https://en.wikipedia.org/wiki/Don't_repeat_yourself


I see that several readers have already respond with pieces of the 
following.  You might want to check the whole shopping list:

https://wiki.debian.org/Hostname


If and when you get tired of looking for needles in the haystack, and/or 
you find them inside binary files that you dare not edit, you may 
realize that your best bet is to backup, wipe, reinstall with the new 
hostname, and restore.  Or, you could just do that first and forget 
about searching the haystack.

Sorry, I didn't spot it was part of your quote because of gene in
the second line. Using RedHat might explain the localhost.localdomain,
but not the addition of .com. AIUI RedHat's addition of
localhost.localdomain was the main reason that Debian inserted
it, only to remove it again. I think localhost, on its own,
has been recommended for years. RFC 1912 dates from 1996.

Following the addition, there was a discussion on devel,
which I understood to conclude with the sentiments in
https://lists.debian.org/debian-devel/2005/10/msg00572.html
and its removal.

A little OTT, but if that's the case, then all the more reason to read
RFC 1178 *before* you name the machine at all, and never change it.
Of course, you can always rotate that to 8117 if you're intensely private.

Cheers,
David.

hostnamectl should do it - and it will be permanent

hostnamectl set-hostname [whatever_you_want_goes_here]

But sudo that doesn't give it a domainname even if you rename it fqdn 
style, so I put it back.
