Sys::Hostname

NAME

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

SYNOPSIS

  1. use Sys::Hostname;
  2. $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.
