No, not if your machine is setup to be identified with a fully-qualified 
hostname.
The default in ldmadmin-pl.conf is, in fact, to set $hostname to the value of
`uname -n`.  A check is made later to see if this is, in fact, a fully qualified
name (i.e., rosebud.rap.ucar.edu, not rosebud).

Your system administrator(s) should setup your machines to have fully qualified
hostnames.  If they are, then you do not have to edit ldmadmin-pl.conf to set
a name by hand.

> THANKS,

No worries.

Cheers,

Tom
