i want to write simple socket program which will listen on socket . here is the code
Code:
## read msg on socket
#! /usr/bin/perl
use IO::Socket::INET;
my $MySocket= IO::Socket::INET->new(LocalPort=>1234,
Proto=>'udp') ;
while () {
$MySocket->recv($text,128);
if ( $text =~ /Done/i )
{
print " ftpdone\n" ;
} else
{
print " FTP Failed :Msg from Server [$text]\n" ;
exit 1 ;
}
}
## send message to socket
use IO::Socket::INET;
$MySocket=new IO::Socket::INET->new(PeerPort=>1234,
Proto=>'udp',
PeerAddr=>'zzz.zzz.zz.zz');
$msg="ftp failed" ;
$MySocket->send($msg);
now i want is that receiver program should try to read on port for 10 sec if no msg is received then wait for minute and again check for message for 10 sec do this for 10 minutes ( inshort check if any message is received in 10 minutes )
but code waits at
Code:
$MySocket->recv($text,128);
line for mesg till it receives msg. Timeout => 10 is not working
what else i can do ? any other module ?? or any work around ??
Suppose i am writing a C program which is going to use Socket calls. I want to use a Unix port for my Socket.
How can i determine a port which is not already in use? (1 Reply)

log::log4perl::appender::socket
Appender::Socket(3pm) User Contributed Perl Documentation Appender::Socket(3pm)NAME
Log::Log4perl::Appender::Socket - Log to a socket
SYNOPSIS
use Log::Log4perl::Appender::Socket;
my $appender = Log::Log4perl::Appender::Socket->new(
PeerAddr => "server.foo.com",
PeerPort => 1234,
);
$appender->log(message => "Log me
");
DESCRIPTION
This is a simple appender for writing to a socket. It relies on IO::Socket::INET and offers all parameters this module offers.
Upon destruction of the object, pending messages will be flushed and the socket will be closed.
If the appender cannot contact the server during the initialization phase (while running the constructor "new"), it will "die()".
If the appender fails to log a message because the socket's "send()" method fails (most likely because the server went down), it will try
to reconnect once. If it succeeds, the message will be sent. If the reconnect fails, a warning is sent to STDERR and the "log()" method
returns, discarding the message.
If the option "silent_recovery" is given to the constructor and set to a true value, the behaviour is different: If the socket connection
can't be established at initialization time, a single warning is issued. Every log attempt will then try to establish the connection and
discard the message silently if it fails. If you don't even want the warning, set the "no_warning" option to a true value.
Connecting at initialization time may not be the best option when running under Apache1 Apache2/prefork, because the parent process creates
the socket and the connections are shared among the forked children--all the children writing to the same socket could intermingle
messages. So instead of that, you can use "defer_connection" which will put off making the connection until the first log message is sent.
EXAMPLE
Write a server quickly using the IO::Socket::INET module:
use IO::Socket::INET;
my $sock = IO::Socket::INET->new(
Listen => 5,
LocalAddr => 'localhost',
LocalPort => 12345,
Proto => 'tcp');
while(my $client = $sock->accept()) {
print "Client connected
";
while(<$client>) {
print "$_
";
}
}
Start it and then run the following script as a client:
use Log::Log4perl qw(:easy);
my $conf = q{
log4perl.category = WARN, Socket
log4perl.appender.Socket = Log::Log4perl::Appender::Socket
log4perl.appender.Socket.PeerAddr = localhost
log4perl.appender.Socket.PeerPort = 12345
log4perl.appender.Socket.layout = SimpleLayout
};
Log::Log4perl->init($conf);
sleep(2);
for(1..10) {
ERROR("Quack!");
sleep(5);
}
