asterisk users - Oct 2013 - Failed to authenticate user 1000<sip:1000@MY_OWN_IP_ADDRESS>; tag=03f82bb9

Hi,

I get a lot of these messages on my Asterisk CLI:

"Failed to authenticate user 1000<sip:1000 at
MY_OWN_IP_ADDRESS>;tag=03f82bb9"

as if my PBX machine is trying to authenticate to itself. It seems 
someone is attacking my asterisk PBX.

Is there a way to fix this problem?

Thank you.

Giorgio Incantalupo

Well, you could use some software like denyhosts or fail2ban to block an IP
after a predefined number of (failed) authentication attempts.

Regards,

Ricardo
