exchanging strings on the network

bahadur has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I am trying to exchange strings between two perl programs. e.g
SCRIPT1. how are u.

SCRIPT2. i am fine.\n

SCRIPT1. whats up.\n

SCRIPT2. nothing much\n
i am using IO::Socket::INET. I have two problems. First, i am unable to exchange strings with each other. secondly i take the hostname and port number from command line. but when i try to do some thing like this

my $client = IO::Socket::INET->new(
                        PeerAddr => '$host',
                        PeerPort => '$port',
                        Proto => 'tcp',)
[download]

it gives me an error that it cannot connect. but when i replace the values with hardcoded ones it works ok. can any one write up full running code where i can exchange strings between two scripts using IO::SOCKET::INET. also the host and port number have to be taken from the command line.

Try `PeerAddr => "$host",`, perhaps you could also read perlquot. holli, /regexed monk/	[reply] [d/l] [select]

Are you sure those variables contain what you think? put a `print` in your code and check that. If that doesn't work, post what you have tried so far. `print "PeerAddr:$host:, PeerPort:$port:\n";` [download] holli, /regexed monk/	[reply] [d/l] [select]
