Question on changing hostname

Hi folks,


Ubuntu 7.04 server amd64


I need to change hostname from;

Code:

ubuntu.satimis.com

to:

Code:

mail.satimis.com

Apart making changes on;

1)
$ sudo postconf -e myhostname=mail.satimis.com
$ cat /etc/postfix/main.cf | grep myhostname

Code:

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
myhostname = mail.satimis.com

$ sudo /etc/init.d/postfix restart

Code:

 * Stopping Postfix Mail Transport Agent postfix                         [ OK ] 
 * Starting Postfix Mail Transport Agent postfix                         [ OK ] 

2)
Edit /etc/hosts as;

Code:

127.0.0.1       localhost.localdomain   localhost
192.168.0.10    mail.satimis.com        mail

# 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

Edit /etc/hostname as;

Code:

mail.satimis.com

$ sudo newaliases
$ sudo hostname mail.satimis.com
Both w/o complaint


$ uname -n
mail.satimis.com
$ hostname -a
mail
$ hostname -s
mail
$ hostname -d
satimis.com
$ hostname -f
mail.satimis.com
$ hostname
mail.satimis.com
$ hostname -i
192.168.0.10
$ hostname -y
(none)


I don't have /etc/sysconfig/network file and "sysconfig" directory


Please advise any other files I need to edit as well. TIA


Edit:

Found following errors:-


1)
$ cat /etc/resolve.conf;

Code:

nameserver 202.14.67.4
nameserver 202.14.67.14
satimis@#ubuntu

202.14.67.4
202.14.67.14

are DNS of ISP.

I think there is a mistake here. Whether delete "satimis@#ubuntu" and replace it with "mail.satimis.com"?


2)
At booting on text scrolling;

Code:

Warning:unable to determin IP address of 
'ubuntu_mail.satimis.com' error: no value servers 
configured - Fatal error processing configuration file 
'/etc/proftpd/proftpd.con   [fail]

3)
Login as satimis. On console, it prompt;

Code:

satimis@#ubuntu
mail:~$ 

2 lines

Not

Code:

[email protected]
mail:~$

4)
$ dig MX mail.satimis.com

; <<>> DiG 9.3.4 <<>> MX mail.satimis.com
