sudo didn't work in a fresh install of Ubuntu 5.10 Colony 4

[Alexander Botero]

Hello,

A possible diagnostic on the 'sudo' problem.

The Debian's (and Ubuntu's) version of 'sudo' terminates straight after it 
has checked and failed to retrieve this machine's *long* hostname (long 
hostname is also also called FQDN (Fully Qualified Domain or Host Name)). 

NOTE: YOU MUST ENABLE ROOT PASSWORD BEFORE TRYING THESE TESTS.
Make a test:

a) Get current hostname of this PC (it's a short hostname)
$ hostname 
084202074190 

The name "084202074190" is OK. It is retrieved and set by dhcp (dhclient) 
via /etc/resolv.conf and other normal network settings (what I know). And 
sudo (sudo.c) gets it by gethostname(....) call.
------------------------------ 
b) Get current long hostname of this PC (also called FQDN)
$ hostname --fqdn
hostname: Unknown host <-------------- Oops, It failed!

(You can also say: "hostname --long")

The Ubuntus version of sudo just prints an error message and terminates 
after it has failed on this check !
It should'n be so rigid.
---------------------------------

How to fix it??

Set a proper (long) hostname manually. Like this 
$ su -c "hostname my.own.hostname.com <http://my.own.hostname.com/>"

( or: sudo hostname my.own.hostname.com <http://my.own.hostname.com/> )

Check it:
$ hostname --long
my.own.hostname.com <http://my.own.hostname.com/>

The original sudo command in Ubuntu Colony 4.
$ sudo 
usage: sudo [-HPSb] [-p prompt] [-u username|#uid]
{ -e file [...] | -i | -s | <command> }

IT WORKS NOW.
---------------------------------------------------------------------

But do not try 
$ su -c "hostname my.own.hostname.org <http://my.own.hostname.org/>"

Ubuntu's sudo command SUCKS a lot !!
