Re: Can I further block dodgy attempts at passwording

[Robert Chalmers (Author)]

Such as this one?

Jul 06 08:10:03 www postfix/smtpd[6155]: disconnect from unknown[45.125.65.52] 
ehlo=1 auth=0/1 quit=1 commands=⅔

So I have anyway written this to find them 
sudo grep unknown /var/log/postfix.log | grep -E -o 
"([0-9]{1,3}[\.]){3}[0-9]{1,3}" | sort -n | uniq > output.txt

Take out my own network and localhost etc, and put them into pfct’s badguys

works nicely.

thanks
robert
