How to change host name in Ubuntu Server 6.06 LTS?

Posted 08-28-2007 at 04:37 AM by rupeshpra

How to change host name in Ubuntu Server 6.06 LTS? Can anyone suggest me what should i do?
why is not anyone reading my blog or none knows the answers for my query?
Actually i've setup the Ubuntu SErver with LAMP,Bind9,Postfix,SSH,Webmin,Dovecot IMAP,POP3,
and while doing so i had misspelled the hostname and now i need to change without affecting the rest of the whole system,
Once i had tried this but it didnt worked out, " sysctl kernel.hostname=newhostname"...
