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; }
