in reply to How do I tell if a remote site is up?

use Net::Telnet f.e.
use Net::Telnet; if ( my $t=new Net::Telnet(Port => 80, Host => "localhost", Timeout => + 5 )->open() ) { print "localhost is active"; $t->close(); };
Or in shell,
echo "."|telnet localhost 80
This should do the trick

[LanX]: oh you want the result line by line?
[jdporter]: ok, LanX, then what?
[jdporter]: It doesn't have to be line by line. Just "my program" "writes" to the external prog and also/then "reads" from it.
LanX open (You are not allowed to open to a command that pipes both in and out, but see IPC::Open2, IPC::Open3, and Bidirectional Communication with Another Process in perlipc for alternatives.)
[jdporter]: IPC::Open2, I guess
[jdporter]: yes, that
