*What* is "all gone"? Show us commands and their output, and then explain
why the output is not what you expected.
/etc/hosts
If you're using short-form hostnames like this:
unicorn:~$ hostname
unicorn
then yeah, that's all you need. If you're using long-form hostnames
(with dots in them), then you also need to configure /etc/hostname.
I use the short-form hostnames, so mine is simply:
unicorn:~$ cat /etc/hostname
unicorn
Couldn't be simpler, really.
.
You saw my hosts entry in the last post, but again
192.168.71.3 coyote.home.arpa coyote
but after a reboot, domainname returns none, and the /etc/domainname
file has been deleted. As in not visible to an ls of /etc. hostname
works as it should. My hosts file is all long form, dotted names with a
trailing alias.
So I just sudo edited /etc/domainname, and entered "home.arpa\return"
and wrote the flle.
results:
gene@coyote:/etc$ sudo nano domainnane
[sudo] password for gene:
gene@coyote:/etc$ domainname
(none)
gene@coyote:/etc$ cat domainname
cat: domainname: No such file or directory
now I see the typu. sudo mv to fx the files name. but even with a
corrected filename visible to an ls:
gene@coyote:/etc$ domainname
(none)
gene@coyote:/etc$ cat domainname
home.arpa
I'd reboot again, but that, by the time I get everything remounted and
my system fully operational, takes me entering my pw about 20 times.
when done I am logged into 6 other machines via an ssh -X login to each,
and I've a sshfs file transfer link setup to each so mc can copy work
output around. Then I can go to work.
Why was the domainname I set and could see with a cat, deleted by a
reboot? Seems to be the question for the day... I sure didn't delete
it. But it was gone after a reboot. Seems to me there ought to be a
PERMANENT way to do this. Now, even if the file exists, its ignored.
Cheers, Gene Heskett.
