title: fail2ban: how unban ip (using fail2ban-client)
body: <p>I using fail2ban v.0.8.2 but I can't unban an IP:</p>
  
  <p>with fail2ban-client I see IP:</p>
  
  <pre><code>fail2ban-client status fail2ban
  
  Status for the jail: fail2ban
  |- filter
  |  |- File list:    /var/log/fail2ban.log 
  |  |- Currently failed: 1
  |  `- Total failed: 8
  `- action
     |- Currently banned: 2
     |  `- IP list:   151.10.65.197 151.10.72.169 
     `- Total banned: 2
  </code></pre>
  
  <p>from man page should be sufficiently do:</p>
  
  <pre><code>fail2ban-client get fail2ban actionunban 151.10.65.197
  </code></pre>
  
  <p>output of command does not return error but:</p>
  
  <pre><code>iptables -L -nv |grep -b2 -a1 151
  
  16262- pkts bytes target     prot opt in     out     source               destination

  16440:    0     0 DROP       all  --  *      *       151.10.65.197        0.0.0.0/0

  </code></pre>
  
  <p>and the output of </p>
  
  <pre><code>fail2ban-client status fail2ban 
  </code></pre>
  
  <p>is same of above, hence command does not run.</p>
