</div>FYI: after I added 193.190.67.15 to /etc/shorewall/blacklist and restarted<br>
shorewall, the traffic stopped. To save you a whois: that's Belnet, a very<br>
reputable Belgian research network that interconnects all Belgian<br>
universities and that also has a large Linux mirror. They are supposed to<br>
be "good guys".<br>
