Re: [xmail] Knowing who is failing Auth Logins
-Message d'origine- De : xmail-boun...@xmailserver.org [mailto:xmail-boun...@xmailserver.org]De la part de Rob Arends Envoye : jeudi 20 janvier 2011 07:32 A : 'XMail Users Mailing List' Objet : Re: [xmail] Knowing who is failing Auth Logins Hi Francis, I have solved this, and then read your mail below. I basically did what you wrote. Wireshark did not decode for me, but I found that each attempt was the same user/password. I just used the text shown in Wireshark and pasted into some online base64 en/decoder. As they were all the same encoded text, I began to suspect a user and not an attack. Here's the egg It was my father's ADSL router attempting to send it's log to me. The same one I configured a couple of months ago to send me the log, so I could use the src IP in a poor man's dynamic-dns resolver. Except I typo'd the SMTP auth user name. :-( The key to it was that he usually leaves his PC on, and I was suspecting an infection of some kind, but today he is away and turned it off. So it started me thinking, if his PC is off, what could be sending from his IP address - the router !!! Thanks to all. (Still would be nice if the pop3/smtp logs showed the user-id used in a failed login attempt. It would help tracking the source down.) Rob :-) Yes, would be a good debug option to have them (user login and name received) written on smtp log on failed attempts (Don't remenber if in pop logs any message for failed attemps with user/pass used ... just remember a pop log setting to not write passwords on normaly 'success' attempts) ___ xmail mailing list xmail@xmailserver.org http://xmailserver.org/mailman/listinfo/xmail
