I have made many attempts to contact Wanadoo regarding this.

heh .. good luck. wanadoo seems quite happy to be quiet about it. mayeb if
you phrase it in french ... i dunno.

whats amusing is that french copyright is extremely easy to enforce. maybe
if you approach it as a copyright matter (likely warez trading, possibly
ftpd exploit hopes thogh) they'll take it more seriously.

My questions, has anyone else noticed this?  I am almost certain
others have.  But more importantly, is there an easy way for me to
find out all the networks that belong to wanadoo so I can just block
them all rather than waiting for a connection from a host in each
network?  Sorry if that's a dumb question, i am kind of new to this.
(many thanks to this list! i have learned alot!)  Oh, and am I over
reacting here?  I know these probes happen all the time, but when they
happen at all 20+ of our sites coming from the same network for
several weeks...  ?

you're certainly not alone. it can't hurt to block their access to ftp
(20, 21 tcp) at the door. blocking all access may be a bit too much,
imagine if you're overseas on business using a wanadoo.fr line ... your
site policy should be pretty strict anyhow for non-standard communications
(web, mail) ...

best of luck,
