Sys::Hostname - Try every conceivable way to get hostname
use Sys::Hostname;
$host = hostname;
Attempts several methods of getting the system hostname and then caches the result. It tries the the C library's gethostname(). If that fails it dies.
All NULs, returns, and newlines are removed from the result.
