Hi
I have 2 simple scripts to send short files from a win2k box to HP unix box ( for learning purposes only). They work fine, but I am looking for ideas on why the client (win2k) needs a sleep statement after each line write. If I leave it out, I get a "Connection reset by peer" on the receiving end(unix) Thanks and the relative code is below: 
# Server (Receiver on Unix end)
if ($pid = fork) { # parent           
            close(C); 
            waitpid( -1, &WNOHANG );
            next; # ready for another client
        } else  {
            # child
            die "can't fork: $!" unless defined $pid;
            close(S); 
            print C "Connected to $ip:$port ";
            # get file name
            sysread(C, $fname, 128)  or die "couldn't read: $!\n&
+quot;;
            $fname =~ s/\n//; 
            print "recieving file: $fname\n";
            while ( sysread(C, $buf, 128) ) {
                 $msg .= $buf;
            }
            open (F, ">$fname") or die "couldn't ope
+n it: $!";
            # open a new file with the file name and write to it
            print F $msg;
            close F;
            print "Recieved file\n";
            exit;
        }
------
# client (win2k sender)
socket(SOCK,AF_INET,SOCK_STREAM,$proto) || die "$0:Cannot open so
+cket\n";
connect(SOCK, $remote) or die "can't connect: $!\n";
# send filename to server
print "sending file $fname\n";
$bytes = syswrite(SOCK, $fname, length($fname));
sleep 1;
open(F, "<$fname") or die "coundn't open: $!";
@buf = <F>;
foreach $line (@buf) {
     # why do we need to sleep ?
      syswrite(SOCK, $line, length($line)) or die "can't write: $
+!";
      sleep 1;
}
close F;
