				Problema porte con Squid...
			 
		Ciao, ho alcuni problemini ad aprire una porta con squid.. Ho necessità di collegarmi al webmin su alcune macchine esterne, già configurate per accettare connessioni sulla 10000. Ho aggiunto la riga: Codice: acl Safe_ports port 10000 # webmin Codice: 1223995346.087 102 192.168.1.111 TCP_MISS/503 1459 GET http://www.mioserv.it:10000/ - DIRECT/- text/html

		Quando riavvii squid con /etc/init.d/squid restart sia in sylog che in /var/cache/squid/cache.log dovresti poter leggere gli eventuali errori nel parse delle acl. C'è qualcosa?

		Ovviamente bypassando il proxy funziona tutto correttamente... attraverso squid l'errore è questo: Codice: ERROR

		Niente, nè commentandola, nè sostituendola con allow Safe_ports... Nell'access.log trovo questa riga in concomitanza al tentativo di accesso: 1224144183.454 101 192.168.1.111 TCP_MISS/503 1459 GET http://serv.miodom.it:10000/ - DIRECT/- text/html

  Ho provato a fare un telnet sulla porta 10000 dalla macchina squid e da lì vedo che questa non ha problemi ad accedere al server esterno. Poi ho provato col mio pc che ha accesso diretto al web bypassando il proxy ma lavorando sempre dietro al fw (il che mi fa desumere che il problema sia proprio di squid). Usando lynx dallo squid: Codice: [root@squid /]# lynx http://www.mioserv.it:10000 Codice: ______________________________________________________________________________________________________________________
