Thanks again! -----Original Message----- From: Marco Schuth [mailto:marco@xxxxxxxxxxxxx] Sent: 02 December 2010 05:19 PM To: 'JC Putter' Subject: AW: java squid Hey, As Mr. Hildebrandt said, which Java Application is that ? Tell us a lil bit more about the Pgm. Usally this happens when Java SSL connects to a unsecure Endpoint Connection. (Plain Text) So I think, that this programm doesn´t aim to the correct Port. Maybe Squid rewrite / redirect the Dst Port of the Pgm ? But we need more informations, look what tcpdump print on std. out, at the Proxy Server and write it down here. Have you maybe a Stacktrace Error of Java in front of you which you can appen here ? -- Mit freundlichen Grüßen Marco Schuth
