Well, I cant figure out how to get a line into a variable from a socket, and do some checking on it. Its this piece of code iam troubled with:

print $client "username:";
$login=<$client>;
print $login;
[download]

Ignore the last code, since I first have to figure out this line to fix the others :) I need the user to type down a username, and put it in the variable $login. Then the script does some checking on it. Doesnt seem to work though.. :( This is the entire script as it is now :

#!/bin/perl
use IO::Socket;
use IO::Select;
$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";
$msg = "";
while ( <$client>) {

next unless /\S/;
if (/c|C/i) {
print $client "<<<Create new user>>>\n\r";
print $client "Login must be at least 6 characters.\n\r";
&login;
}
elsif (/l|L/i) {
&logon;
}
}

sub login {
print $client "username:";
$login=<$client>;
print $login;

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

open (FILE1, "users.txt") || print "Error occured while opening file";
while (<FILE1>) {
($first, $second ) = split /:/;
if ($login eq $first) {
do {
print $client "Sorry this username has been taken, try again!\n\r";
&login;
} while ($login eq $first);
}
}
if (length($login) > 6) {
print $client "Your username was longer than 6 characters!\n\r";
&login;
}
close (FILE1);
$pass = password();


sub password { 
print $client "Password:";
$password=<STDIN>;
chop $password;
print $client "\n\rRe-enter password:";
$password2=<STDIN>;
chop $password2;
if ($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;
}
