Hi,

(quoting from the thread: will denyhosts work with journald (without rsyslogd)?)

While reading about the recently found SSH vulnerability, I came across
a rather uncontested opinion that fail2ban does not work with IPv6,
e.g. see this reddit thread:

https://www.reddit.com/r/netsec/comments/3dnzcq/openssh_keyboardinteractive_authentication_brute/

Personally, I found the "parse log files to ban" idea a bit shaky to
begin with.  The same thread mentions pam_shield (also available in the
Fedora repos).  A bit of reading on it makes it seem more robust than
fail2ban.  I was wondering if anyone had any experience or opinion
on this topic.

Cheers,
