[Pdns-users] protect using fail2ban

[Steffan Noord]

Hello list,

Im new to fail2ban and want to secure pdns-server3.1
I found a treat with

in /etc/fail2ban/filter.d/pdns.conf: 
====== 
[Definition] 
failregex = pdns(?:\[\d{1,5}\])?: Not authoritative for '.*',.*sending 
servfail to <HOST> \(recursion was desired\) 
ignoreregex = 
====== 

  jail.conf: 

  ======== 
  [pdns-qdomain] 
  enabled = true 
  #port = domain,8053 
  protocol = udp 
  filter = pdns 
  logpath = /var/log/daemon.log 
  bantime = 259200 
  maxretry = 2 
  ========

But when starting fail2ban im getting a error:

ConfigParser.ParsingError: File contains parsing errors: /etc/fail2ban/filter.d/pdns.conf
        [line  3]: 'servfail to <HOST> \\(recursion was desired\\) \n'

Can someone help me setup fail2ban ?
Thanxs

Steffan
