How to change the hostname

[Lynette Guanzon]

Hello,
I tried to use set_parms to change the hostname, but after a reboot it went back to the original hostname. I also tried the "unsupported" method by changing the ff:
/etc/hosts
/etc/rc.config/netconf

To no avail, it still comes back with the old hostname after a reboot. What else can I do so that the system keeps the new hostname?

I appreciate any assistance.
Thank you,
Lynette

change /etc/rc.config.d/netconf
- will handle reboot

change /etc/hosts

do the hostname command again.

Hi
How long is your hostname. It needs to be less then 8 char or you will have problem

Hi Charles,
I tried that one too but it still did not work.
Any other ideas?

Thanks,

What is your current hostname?
do a hostname command to find out.

What do you want to change it to?

Hi Sachin,
My hostname is only 7 characters long. The only difference between the old and new hostname is the last character (a digit change).

Hi Charles,
The old hostname is techfw2. The new hostname is techfw1. What I do then to get around it is to set the hostname manually after every reboot. So currently, since I changed it manually, it has the new hostname of techfw1.

Hi
you are on right track
only two file plays part on it. /etc/hosts and /etc/rc.config.d/netconf.

After changing this two file, brought system in single user mode and check the name.

Try changing to different name like star2.
do you use DNS for name resolv?

Hi Charles,
Thanks for the link, but I've read this before already.

Hi Sachin,
Yes we are using DNS. I will try to bring it down to single user mode. I'll let you know as soon as this is done.

Thank you to both of you!

SAM--->Networkin and Communications --->Network Interface Card ----> ACTION Field ( modify System Name )

Sometimes SAM does the magic tooo.

Lynette,

If still unsuccessful, please provide the output from the following commands:

# grep techfw /etc/hosts
# grep techfw /etc/rc.config.d/netconf
# hostname
# uname -a

This will help me to help you.
