Top Forums Shell Programming and Scripting [PERL] Check if socket is connected before sending data Post 302981435 by Lord Spectre on Tuesday 13th of September 2016 04:53:28 AM

No one? Smilie

Adding the code I tried, just in case. With that, after server disconnection I got:
Code:
Bad arg length for Socket::pack_sockaddr_in, length is 14, should be 4  at /usr/lib/perl5/5.8.8/IO/Socket/INET.pm line 224, <$fh> line  35302.

Code:
my $sock = new IO::Socket::INET(
                    PeerAddr => '192.168.10.152',
                    PeerPort => 8000,
                    Proto    => 'tcp');
  $sock or die "no socket :$!";

  open(my $fh, '<:encoding(UTF-8)', 'list1.txt')
      or die "Could not open file $!";

  while (my $msdn = <$fh>) {
        my $port="8000";
        my $ip="192.168.10.152";
        unless ($sock->connected) {
          $sock->connect($port, $ip) or die $!;
    }
    my $str="DATA TO SEND: " . $msdn;
    print $sock $str;
  }
  close($sock);

Socket::GetAddrInfo::Strict(3pm)			User Contributed Perl Documentation			  Socket::GetAddrInfo::Strict(3pm)

NAME
"Socket::GetAddrInfo::Strict" - Provide Socket::GetAddrInfo functions which throw exceptions SYNOPSIS
use Socket qw( SOCK_STREAM ); use Socket::GetAddrInfo::Strict qw( getaddrinfo getnameinfo ); use IO::Socket; my $sock; my %hints = ( socktype => SOCK_STREAM ); my @res = getaddrinfo( "www.google.com", "www", \%hints ); while( my $ai = shift @res ) { $sock = IO::Socket->new(); $sock->socket( $ai->{family}, $ai->{socktype}, $ai->{protocol} ) or undef $sock, next; $sock->connect( $ai->{addr} ) or undef $sock, next; last; } if( $sock ) { my ( $host, $service ) = getnameinfo( $sock->peername ); print "Connected to $host:$service "; } DESCRIPTION
Socket::GetAddrInfo provides the functions of "getaddrinfo" and "getnameinfo", which return lists whose first element is error value, or false indicating no error occured. This module wraps the functions provided by "Socket::GetAddrInfo" to check this error value, and throw an exception (using "die") if an error occured. If not, then the remaining values are returned as normal. This can simplify the logic of a program which otherwise simply throws its own exception on failure anyway. FUNCTIONS
@res = getaddrinfo( $host, $service, $hints ) After a successful lookup, returns the list of address structures, as documented in Socket::GetAddrInfo. If the lookup fails, an exception containing the string form of the error is thrown instead. ( $host, $service ) = getnameinfo( $addr, $flags, $xflags ) After a successful lookup, returns the host and service name, as documented in Socket::GetAddrInfo. If the lookup fails, an exception containing the string form of the error is thrown instead. AUTHOR
