[Denyhosts-user] DenyHosts Plugin That Notifies ISPs of Attack / CentOS

[S A I N T - 4 2 <sa...@gm...>]

I noticed in my /var/log/secure that the format of the ssh log is


Jul 27 05:57:59 tyesun sshd[2342]: refused connect from 
::ffff:151.200.214.83 (::ffff:151.200.214.83)


When I look at notify_isp.log , I have only 2 lines, the ones that I 
tried manually.

I believe notify_isp.log does not like the IPV6 stuff. I am removing 
IPV6 from my server by doing

- Editing /etc/modeprobe.d/blacklist , and adding blacklist ipv6
- Editing /etc/sysconfi/network a, and adding NETWORKING_IPV6=no
