NAME
Sys::Hostname::Long - Try every conceivable way to get full hostname
SYNOPSIS
use Sys::Hostname::Long;
$host_long = hostname_long;
DESCRIPTION
How to get the host full name in perl on multiple operating systems (mac, windows, unix*
etc)
DISCUSSION
This is the SECOND release of this code. It has an improved set of tests and improved
interfaces - but it is still often failing to get a full host name. This of course is the
reason I wrote the module, it is difficult to get full host names accurately on each
system. On some systems (eg: Linux) it is dependent on the order of the entries in
/etc/hosts.
To make it easier to test I have testall.pl to generate an output list of all methods.
Thus even if the logic is incorrect, it may be possible to get the full name.
Attempt via many methods to get the systems full name. The Sys::Hostname class is the best
and standard way to get the system hostname. However it is missing the long hostname.
Special thanks to David Sundstrom and Greg Bacon for the original Sys::Hostname
SUPPORT
This is the original list of platforms tested.
MacOS Macintosh Classic OK
Win32 MS Windows (95,98,nt,2000...)
98 OK
MacOS X Macintosh 10 OK
(other darwin) Probably OK (not tested)
Linux Linux UNIX OS OK
Sparc OK
HPUX H.P. Unix 10? Not Tested
Solaris SUN Solaris 7? OK (now)
Irix SGI Irix 5? Not Tested
FreeBSD FreeBSD OK
A new list has now been compiled of all the operating systems so that I can individually
keep informaiton on their success.
THIS IS IN NEED OF AN UPDATE AFTER NEXT RELEASE.

KNOWN LIMITATIONS
Unix
Most unix systems have trouble working out the fully quallified domain name as it to be
configured somewhere in the system correctly. For example in most linux systems (debian,
?) the fully qualified name should be the first entry next to the ip number in /etc/hosts

If it is the other way around, it will fail.
