Hi,

I need to change the hostname and ip address of a tru64 unix server running version 4.0F.

how can i do this. this server is a production machine.

Another question :

Does inetd stop/start drop all user sessions

Thanks

Hi Patrick,

- NETWORK CONFIGURATION:
In order to change the network configuration all you have to do is launching

# netsetup

It will ask you the new configuration with new IP address and subnet mask.
Only pay attention to this thing: after changing network configuration you should umount/mount all filesystems in /etc/fstab or execute a reboot:

# /usr/sbin/shutdown -r now

Besides: if you want to change the domain (if it is needed) you can launch

# bindsetup

Anyway man of both commands could give you other useful informations.

- CHANGE HOSTNAME:
About change of hostname, you can change it by vi on file /etc/rc.config.
This change should be immediately recognized on system. You can try by command after the change into file above:

# hostname

- INETD QUESTION:
stop/start of inetd will not drop users sessions, but you should know that when inetd is stopped, other connections on system will not be possible.

Best regards,

Just last note on my post: of course you should restart network services:

# /usr/sbin/rcinet restart

In this instance you should warn users, this could drop down user sessions.

If you won't interrupt server activity and new ip is within the same network range you can use the "alias" parameter for ifconfig to configure a second IP-adress:

# ifconfig tu0 alias 10.0.0.2

to make it permanent use

# vi /etc/rc.config
IFCONFIG_1="alias 10.0.0.2"
NETDEV_1="tu0"
NUM_NETCONFIG="2"
