You *did* properly escape the command string, right?  Otherwise,

my $str = `ssh -n user AT machine DOT domain ls`;

will try to interpolate the contents of the array @machine into the
command...  You need to use

my $str = `ssh -n user\@machine.domain ls`;

BTW, the -n flag is still useful, since some commands don't properly run
otherwise.
