Glad to hear that :-) Thanks for the report!

You were right. In the log of the outer firewall I found:

proto=53/udp src= dst= msg=Ceiling for
number of connections reached, dropping packet Src 1390 Dst 53 from SELF

It seems, the firewall was overwhelmed by DNS requests. The same
apparently often happens with bitTorrent and similar tools when using
this sort of hardware (a Linksys firewall). I should go back to a
self-maintained, Linux-box as firewall or setup a local, more
intelligent DNS.

Is there a chance to limit the amount of simultaneous DNS requests in
buildout? Or to get the names of failed eggs displayed when running
buildout without '-v'?

Right, again.

Now it's:

index = http://download.zope.org/ppix
eggs-directory = /home/uli/buildout-eggs
newest = false
download-cache = /home/uli/eggs/download-cache

and yes, with ppix it works much smoother (although still errors occur,
but *far* less than before). Thanks for the hint! Now I know where to
catch the problem :-) Sorry for the off-topic.

Good hint! Use it, guys!
