Blocking Icmp Echo

LISa is a small daemon which is intended to run on end user systems. It provides something like a "network neighbourhood", but only relying on the TCP/IP protocol stack, no smb or whatever. The information about the hosts in your "neighbourhood" is provided via TCP port 7741. LISa supports two...

Festival::Client::Async is a non-blocking interface to a Festival server. SYNOPSIS use Festival::Client::Async qw(parse_lisp); my $fest = Festival::Client::Async->new($host, $port); $fest->server_eval_sync($lisp, %actions); # blocking $fest->server_eval($lisp); # just queues $lisp for...

ICMPScan scans the specified address, or addresses, for ICMP responses. Usage: icmpscan [ -EPTSNMAIRcvbn ] [ -A address ] [ -f filename ] [ -i interface ] [ -r retries ] [ -t timeout ] target [...] Options: -i, --interface Listen on the specified interface. If unspecified, icmpscan will...
