Re: uname -n output from where?

[Quang Tran <quang_m_tran@yahoo.com>]

Darren,

/etc/myname is supposed to be used by /etc/rc to
initialize the hostname at system boot time.

/etc/rc calls /etc/netstart to do this:
   hostname=`cat /etc/myname`
   hostname $hostname

Verify that your rc related scripts are not doing
something funny with /etc/myname before it sets the
hostname. 

I believe both 'hostname' and 'uname -a' pulls it from
the kernel.

There are 2 ways to set the hostname in the kernel.
1. 'hostname ${name}' command calls sethostname()
function.  'hostname' without arg calls gethostname()
function.

2. 'sysctl -w kern.hostname=${name}' sets kernel
parameter for hostname.  'sysctl kern.hostname'
returns the value of that kernel parameter.

Try using both 'hostname' and 'sysctl' commands to set
the hostname....and make sure that 'uname -n' reflects
the change.  If it does, verify your /etc/myname and
rc scripts then reboot.    

Oh, one other place I can think of is
/etc/sysctl.conf....make sure there's no
"kern.hostname=Molodetz" in there.

Good Luck,
Quang
