The implicit use of global $_ in the client code seems a bit odd. This variable is not set explicitly from the command line without careful invocation:

echo myarg | perl -nle 'print "ARG=<$_>\n"'
ARG=<myarg>

You're better off, at least, fetching from ARGV:

my ($hostname) = @ARGV;
die "usage: $0 hostname" unless $hostname;
my $socket = new IO::Socket::INET ( 
                                  PeerAddr => $hostname, 
                                  PeerPort => '7071', 
                                  Proto => 'tcp', 
                               ); 
 

...or however you want to parse the command line arguments in @ARGV.

$_ is supposed to be $ARGV[0].

PeerAddr => $ARGV[0],

I've also tried using backticks

chomp(my $output = `ls /tmp 2>&1`);

It's like the client isn't waiting for the server to finish
