in reply to Transmit file over socket

I think your server has a logic error. Consider your code:
   ...
   print "Got: $in\n";
   if ($in =~ /#:#$/) {
     ...
   } elsif ($in =~ /_$/) {
     ...
   } elsif ($in =~ /__END$/) {
     ...
   } else {
     ...
     # save file
   }

For the following input data: 
Got: X-Call~4.xml#:#380_<?xml version="1.0"?>

Your logic will never get to the save file bit correctly, it will (almost) always fall inside the $in =~ /_$/ block and not saving the xml header correctly.


You probably want something like this instead:
if ($in =~ /__END$/) {
  # close previous file
} else {
  ($filename, $filesize) = $in =~ /^([^#]+)#:#(\d+)_/;

  if ($filename) {
     # create new file
  }

  # proceed with saving the file
}

    I will look into this - thank you. However, for the first file the filename and size are seperate (which is what I was looking for.. only for the second and following files that get processed are the filename and size and first line concatonated onto the same line. I suspect some kind buffering issue..?

      Could be. Thinking about the client/server program again, I would probably use the Net::TCP::Server module to implement the server. Much easier.
      use strict;
use warnings;
use Net::TCP::Server;

# create listener
my $lh = 'Net::TCP::Server'->new(8000) or die;

while (my $sh = $lh->accept) {
    defined(my $pid=fork) or die "fork: $!\n";
    if ($pid) {             # parent doesn't need client fh
        $sh->stopio;
        next;
    }
    
    # child doesn't need listener fh
    $lh->stopio;
    
    # do per-connection stuff here
    # read from the socket

    exit;
}
