Stop exposing servers to hackers and change [csf.error] -----> csf -x ; csf -e ; instead!

[Centos 8 | Csf v14.04] No blocking and no logging

Hello, ENV: Centos 8, Csf 14.04, iptables enable. I have tried to block a spammer, who installed a cron script to populate every ten and every eleven minutes in logfiles of my server with following: FQDN/login?dst=http%3A%2F%2Fbucket-img.y5en.com%2Fmessage%5Ficon%5Ffriends.png FQDN/login?dst=http%3A...

Re: nftables

In addition to that, nftables is much more efficient. What surprises me is that CSF has still not yet changed it to nftables. It was too late at the time of posting this thread.

Re: Missing binary locations

Re: Whitelisted IP being blocked

csf.ignore is a different area, different sequent of chains. You would still need the IP in csf.allow.

Re: Filtering SMTP abuse?

Did you activate / configure connection tracking? If yes, this will be blocked.
