I need some help understanding SIP dialog. Some actor is trying to access my server, but I can't figure out what he's trying to do ,or how. I'm getting a lot of these warnings.

I'm currently using postfix and dovecot, with dovecot authentication (with saslauthd) using mysql for accounts Is there any option available for me to help inhibit/prevent brute-force login attempts? Thx. Rick Rick Steeves http://www.sinister.net "The journey is the destination"

In https://wiki.dovecot.org/HowTo/Fail2Ban, for a current (I know for a fact in 2.2.36) I believe it should be filter = dovecot instead of filter = dovecot-pop3imap [root at mail ~]# ls -l /etc/fail2ban/filter.d/doveco* -rw-r--r-- 1 root root 1875 May 11 2017 /etc/fail2ban/filter.d/dovecot.conf [root at mail ~]#

So I have this nice, simple web server up running. Its purpose is to allow me external testing with HIP, and to provide some files for external distribution. Of course, there it is sitting on port 80 and the attacks are coming in per logwatch report. Examples from the report include: Requests with error response codes 404 Not Found //phpMyAdmin-2.5.1/scripts/setup.php: 1
