Run "hostname mynewname.com". You will also want to updatee /etc/rc.conf

I see what you mean, that may not help me as my host name is an ip
address running in a jail. There for my host name at the command prompt
is 192# if I change the ip to a name in the /etc/rc.conf I do not
think the jail will run.

Please advise

thanks

Michael

A hostname is not an IP-address.
For a jail, the hostname is given in the commandline. You should change that
for in case you have to restart the jail. Also, you should update /etc/hosts
and /etc/rc.conf to refect the changes. This might be needed for e.g. running
services like Apache and MySQL.

Keep in mind, from man(8) jail:

NOTE: If you plan to allow untrusted users to have root access inside the
jail, you may wish to consider setting the
security.jail.set_hostname_allowed sysctl variable to 0. Please see the
management discussion later in this document as to why this may be a good
idea. If you do decide to set this variable, it must be set before
starting any jails, and once each boot.

maybe i get this wrong, but do you just want to change the name that
appears in your shell prompt? you can make up anything you want for
that, but you have to consult the manpage for your shell.
