I dont know if this will help but here are some examples ive gotten in the past...

<?php
$fp = fsockopen ("phpbuilder.com", 21, $errno, $errstr, 30);
if (!$fp) {
    echo "$errstr ($errno)<br>\n";
} else {
    fputs ($fp, "GET / HTTP/1.0\r\nHost: [url]www.phpbuilder.com\r\n\r\n[/url]");
    while (!feof($fp)) {
        echo fgets ($fp,128);
    }
   # fclose ($fp);
}
?>

<?php

//$cfgUser    = "xxxxxx";
//$cfgPasswd    = "yyyyyy";
$cfgNewsGroup    = "alt.php";

// identification required on private server
if($cfgUser) {
    fputs($usenet_handle, "AUTHINFO USER ".$cfgUser."\n");
    $tmp = fgets($usenet_handle, 1024);

fputs($usenet_handle, "AUTHINFO PASS ".$cfgPasswd."\n");
$tmp = fgets($usenet_handle, 1024);

// check error

if($tmp != "281 Ok\r\n") {
    echo "502 Authentication error\n";
    exit();
}    
}

// select newsgroup

fputs($usenet_handle, "GROUP ".$cfgNewsGroup."\n");
$tmp = fgets($usenet_handle, 1024);

if($tmp == "480 Authentication required for command\r\n") {
    echo "$tmp\n";
    exit();
}    

$info = split(" ", $tmp);
$first = $info[2];
$last = $info[3];

print "First : $first\n";
print "Last : $last\n";
