First I will explain how this program works : When a user wants to create a new user, he needs to type his username. Then this loop will check the file users.txt to see if that username already exists. If so, the user has to type a new username. The file users.txt has entries like this :

test:lamda
beta:alpha
[download]

test = username and lamda = password, seperated by a : However, this loop works perfectly locally. When I try to do this in a client server kind of way, the loop only checks the first 2 lines, and wont continue after that :( The problem lies in this line at the beginning of the entire script:

$/ = "\015\012";
[download]

I had to define this to make sure I would accept proper data from $client. However, when the script checks the file it messes up with the spaces and newlines, because of this defined variable. So I thought I could easily alter that variable before it checks the file like this :

$/ = "\012";
[download]

And change it back later. Now it only checks the first 2 lines of the users.txt file, and not the others.. :( Iam totally stuck. Can anyone help me? The loop Iam talking about is this :

$/ = "\012";
open (FILE1, "users.txt") || print "Error occured while opening file";
while (<FILE1>) {
($first,$second ) = split /:/;
print $first;
if ($login eq $first) {
print $client "Sorry this username has been taken, try again!\n\r";
&login;
}

This is the entire script so far:

#!/bin/perl
use IO::Socket;
use IO::Select;
$/ = "\015\012";
$nconnections_new = 0;
$login = "";
$maxconn = SOMAXONN;
$local=IO::Socket::INET->new(Proto=>"tcp", LocalPort=>"1234", Listen=>
+$maxconn, Reuse=>1)
or die "Can't open socket\n";
while ($client = $local->accept) {
$client->autoflush(1);
&start;

sub start {
print $client "This is a test BBS!\n\r";
print $client "(C)reate new user      (L)ogin";
print $client "\n\r";

my $option=<$client>;
chomp $option;
$option="\U$option\E";

if ($option eq "C") {
print $client "<<<Create new user>>>\n\r";
print $client "Login must be at least 6 characters.\n\r";
&login;
}

elsif ($option eq "L") {
&logon;
}

else { &start; }

sub login {
$/ = "\015\012";
print $client "username:";
$login=<$client>;
chomp $login;

if ($login eq "") {
print $client "Must enter a username!\n\r";
&login;
}

$/ = "\012";
open (FILE1, "users.txt") || print "Error occured while opening file";
while (<FILE1>) {
($first,$second ) = split /:/;
print $first;
if ($login eq $first) {
print $client "Sorry this username has been taken, try again!\n\r";
&login;
}
$/ = "\015\012";
}

close (FILE1);

if (length($login) > 7) {
print $client "Your username was longer than 6 characters!\n\r";
&login;
}

$pass = password();


sub password { 
print $client "Password:";
$password=<$client>;
chomp $password;
print $client "\n\rRe-enter password:";
$password2=<$client>;
chomp $password2;
if ($password ne $password2) {
print $client "Passwords do not match, try again!";
&password;
}
return $password;
}

open (FILE, ">>users.txt") || print "Error occured while opening file"
+;
print FILE "$login:$pass\n";
close (FILE);
print "File written..\n\r";
exit;
}
}
sub logon {
print $client "test";
}


close $client;
