Re: 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
   }
[download]

For the following input data:

Got: X-Call~4.xml#:#380_<?xml version="1.0"?>
[download]

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..? ----- Of all the things I've lost in my life, its my mind I miss the most.	[reply]

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; }` [download]	[reply] [d/l]
