News Server Lookup by ISP Domain
Before you can start exploring the world of Usenet, or 'newsgroups', you need to locate a news server to connect to. In most cases your internet service provider will already provide access to a news server as part of your dialup or high speed internet access account.
For a list of news servers you may be able to use, enter the domain name of your internet service provider, or the domain portion of your email address. For example, if your email address is yourname@yourdomain.com, then enter 'yourdomain.com' as your domain.
Search Results for '" . $emaildomain . "'";
mysql_select_db("newsdb") or die( " | | Database is currently offline. Please try again later. | " );
$result = mysql_query( "select * from newsdb.domsrv where domain='$emaildomain' and public <> 'Y' order by hits desc, server asc" );
$result_rows = mysql_num_rows( $result );
if ( $result_rows == 0 ) {
// Try checking for obvious names
$foundserver = 'no';
$testserver = "news." . $emaildomain;
$ip = gethostbyname( $testserver );
if ( $ip != $testserver ) {
$foundserver = $testserver;
}
else {
$testserver = "nntp." . $emaildomain;
$ip = gethostbyname( $testserver );
if ( $ip != $testserver ) {
$foundserver = $testserver;
}
}
if ( $foundserver == "no" ) {
