bluebox was the hostname when i installed feisty.
IWNETZ was the Workgroup when i used samba to connect with vmware.
System5 is the hostname now (/etc/hostname), but i don't remember when and how
i changed it.
To reproduce it i startet gutsy and done this:
login
-----------------
[EMAIL PROTECTED]:~$ cat /etc/hostname
SystemA
[EMAIL PROTECTED]:~$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 SystemA
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
---------------------------
System->Administration->Network->General->Hostname: SystemA=>SystemB
---------------------------
logout/login
---------------------------
[EMAIL PROTECTED]:~$ cat /etc/hostname
SystemB
[EMAIL PROTECTED]:~$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 SystemB
...
---------------------------------
I can't reproduce the change from SystemB to SystemB.IWNETZ, so edit the file
/etc/hosts.
---------------------------------
[EMAIL PROTECTED]:~$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 SystemB.IWNETZ
...
---------------------------------
restart
----------------------
System->Administration->Network->General->Hostname: SystemB=>SystemC
-----------------------
log out/log in
-----------------------
[EMAIL PROTECTED]:~$ cat /etc/hostname
SystemC
[EMAIL PROTECTED]:~$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 SystemB.IWNETZ
...
-----------------------
I don't know, whether it was a bug under gutsy (or feisty?) that added .IWNETZ
to the line in /etc/hosts, but there may be some computers having such a
(defective?) /etc/hosts and these computers may have a problem when upgrading
to hardy.
The situation
$ cat /etc/hostname
MyHostname
$ cat /etc/hosts
127.0.0.1 localhost
127.0.1.1 MyHostname.MyWorkgroup
...
works under Gutsy, but not under Hardy.
