    <p>Hi Aleksey,</p>
    <p>I'm cc systems@ just to keep them informed of this ongoing attack
      and countermeasures.</p>
    <p>One context in the Sugar Network was being updated with POST
      requests from 20 different hosts, every second or so.<br>
    </p>
    <p>Aleksey, your suggestion to use apache Require directive to block
      them did not work before Apache 2.4, and we have 2.2.<br>
    </p>
    <p>So I enabled the ufw firewall and blocked the following 20
      addresses coming from Russia :-) <br>
    </p>
    <p>I isolated the IPs from apache access logs.<br>
    </p>
    <p>188.143.232.10<br>
      188.143.232.11<br>
      188.143.232.13<br>
      188.143.232.14<br>
      188.143.232.15<br>
      188.143.232.16<br>
      188.143.232.19<br>
      188.143.232.21<br>
      188.143.232.22<br>
      188.143.232.24<br>
      188.143.232.26<br>
      188.143.232.34<br>
      188.143.232.35<br>
      188.143.232.37<br>
      188.143.232.40<br>
      188.143.232.41<br>
      188.143.232.43<br>
      188.143.232.62<br>
      188.143.232.70<br>
      188.143.232.72<br>
    </p>
    <p>I was wondering, I enabled http, https and ssh.</p>
    <p>Aleksey, just doublechecking, do Sugar Network XO clients connect
      over port 80, correct?<br>
    </p>
    <p>Are there other services on jita.sugarlabs.org that require other
      ports open?</p>
    <p>Regards,</p>
    <p>Sebastian<br>
