setting hostname on running system

[Anonymous]

How do you set the hostname on a system without one without rebooting?

I've tried the following sources to find the information:

• FreeBSD handbook: Networking Services chapter
• google.com/bsd search "setting hostname" top 10 results

Am not at my machine right now, but have you tried # /etc/rc.d/hostname restart
?

How do you set the hostname on a system without one without rebooting?

# hostname ${NEW_HOSTNAME}

Verify with

# hostname
${NEW_HOSTNAME}

... but to keep it permanent, remember to put it also in the /etc/rc.conf file.

Just tried killing apache, killing hostname, changing hostname in /etc/rc.conf to hostname="localhost" and then restarting /etc/rc.d/hostname and apachectl but when I checked hostname by entering the commmand "hostname" into the shell it did not show a change in the variable so the hostname didn't appear to have been affected.

@vermaden The ouput of hostname ${localhost} or ${example.com} returns the current value of hostname (The default null-string/Amnesiac?). I then try using hostname to verify using the command "hostname" but it doesn't seem to have changed. Apache after a restart doesn't seem to have noticed as well.

it doesn't seem to have changed.

It have changed here ...

core# hostname
core
core# hostname CORE
core# hostname
CORE

localhost is a reserved hostname (RFC-2606). Don't use it as an actual hostname.

hostname $<myhostname> works, I was retaining the $< & > which seems to have made it not work.
