<p style="margin-left:36.0pt">Hello Colin<o:p></o:p></p>
<p style="margin-left:36.0pt">there were some posts about DFix2/APF round May 5-6 in this list, read what happened there...<o:p></o:p></p>
<p style="margin-left:36.0pt">I was running APF, Dfix2 and Fail2ban on my servers, but I turned Dfix2 off because it is too fussy with users who entered a false password (e.g. connecting an old device or setting up a new one, at the Internet Café etc.), one's
connection is banned by Dfix2 already after two attempts.<o:p></o:p></p>
<pre style="margin-left:36.0pt">less /etc/apf/deny_hosts.rules<o:p></o:p></pre>
<pre style="margin-left:36.0pt"># added 83.76.86.xxx on 12/04/18 12:09:33 with comment: dFixblock2<o:p></o:p></pre>
<pre style="margin-left:36.0pt">83.76.86.xxx<o:p></o:p></pre>
<p style="margin-left:36.0pt">Dfix2 is very compelling, but just too strict. And since I couldn't find out how to edit the rules in
<tt><span style="font-size:10.0pt">/etc/sec</span></tt>, I turned it off keeping APF and Fail2ban only.<o:p></o:p></p>
<p style="margin-left:36.0pt">No problems anymore. Until the next hack?:-(<o:p></o:p></p>

Look at /var/log/sec for anything that might indicate if it was dFix that blocked. If you see something there, we can tune to prevent that happening again.<o:p></o:p></p>
