[RESOLVIDO]Warning: gethostbyaddr(): Address is not a valid IPv4 or IPv6 address

[reinaldo.feitosa]

Senário:
pfSense 2.2
Squid3 3.4.10_2 pkg 0.2.6
SquidGuard 1.4_7 pkg v.1.9.10
Lightsquid 1.8.2 pkg v.2.35

Quando clico em proxy state no proxy report aparece várias vezes (parece ser um erro para cada conexão) o seguinte erro:
Warning: gethostbyaddr(): Address is not a valid IPv4 or IPv6 address in /usr/local/www/sqstat/sqstat.class.php on line 426

Tem um relato de bug na versão 2.1(https://redmine.pfsense.org/issues/3936)
E neste post fala que é só quando tem ipv6. Já desbilitei, mas o erro continua (https://forum.pfsense.org/index.php?topic=81127.0)

[reinaldo.feitosa]

Bom dia!

Continuo com este erro.

Tem um post em inglês https://forum.pfsense.org/index.php?topic=81127.0 que relata o mesmo problema e um Bug checher de 5 meses atrás mas não achei a solução.

Alguém ai com mais experiencia pode me ajudar?

Estou tentando descobrir este erro.

Verifiquei que o conteúdo da variável $IP na linha 426 está vazio.

Analisando o código fonte para este conteúdo está vazio tem que ter um erro nesta function:

	function makeQuery($pass = ""){
		$raw = array();
		# sending request
		if(!$this->fp)
		    die("Please connect to server");

		$out = "GET cache_object://localhost/active_requests HTTP/1.0\r\n";
		if ($pass != "")
		    $out .= "Authorization: Basic ".base64_encode("cachemgr:$pass")."\r\n";
		$out .= "\r\n";

		fwrite($this->fp, $out);

		while (!feof($this->fp)) {
			$raw[] = trim(fgets($this->fp, 2048));
		}
		fclose($this->fp);

		if (!preg_match("/^HTTP.* 200 OK$/", $raw[0])) {
			$this->errorMsg(1, "Cannot get data. Server answered: $raw[0]");
			return false;
		}

		# parsing output;
		$header = 1;
		$connection = 0;
		$parsed["server_version"] = "Unknown";
		foreach($raw as $key=>$v){
			# cutoff http header
			if ($header==1 && $v=="") $header=0;
			if ($header) {
				if(substr(strtolower($v),0,7) == "server:") { # parsing server version
					$parsed["server_version"] = substr($v,8);

			}
			else {

					$connection = substr($v,12);

				if ($connection) {
					# username field is avaible in Squid 2.6 stable
