Install Fail2ban on CentOS/Fedora
Instead of installing with yum install fail2ban, use:
yum install fail2ban-server systemctl enable fail2ban systemctl restart fail2ban
The packet fail2ban also installs the Firewalld, which blocks by default all traffic after restarting the server.
Info: http://pkgs.org/centos-7/puias-unsupported-x86_64/fail2ban-server-0.9.2-1.sdl7.noarch.rpm.html
Enable mail
yum install fail2ban-sendmail
Fail2ban when ssh in telnet port
This are no failures in sense of authentication (because login does not take place).
But if you will that yet, just copy /etc/fail2ban/filter.d/sshd.conf into /etc/fail2ban/filter.d/sshd.local and add following to the failregex:
^%(__prefix_line)sBad protocol version identification '.*' from <HOST> port \d+\s*$
