Hi,

I'm in no way paranoid. My initial problem was, that I couldn't resolv hosts 
like www.slsk.org. So my mlnet was limited to the donkey network. Bittorrent 
and the like need to know which server to access behind torrentse.cx.

The reason seemed to be that I compile mlnet statically linked on my current 
computer, glibc 2.2.x, and run it on my router (so I can't be to paranoid at 
all), which sticks to glibc 2.0.7. With name resolving libs from 2.2.x 
provided mlnet would segfault. There might be a way to have the libs 
(including ld-linux.so) installed in paralell, but  I don't know how to do 
that.

In that case Pierre suggested to run mlnet in a chroot environment to overcome 
the problems. And finally it worked!

So that's the story behind. I'm not uggesting it might be insecure to use 
mlnet.

Great program. Keep on.
