# NAME

Sys::Hostname - Try every conceivable way to get hostname

# SYNOPSIS

        use Sys::Hostname;    $host = hostname;

# DESCRIPTION

Attempts several methods of getting the system hostname and then caches the result. It tries the first available of the C library's gethostname(), ``$Config{aphostname}`` , uname(2), `syscall(SYS_gethostname)`, ``hostname`` , ``uname -n`` , and the file /com/host. If all that fails it `croak` s.

All NULs, returns, and newlines are removed from the result.
