---------------------------------------------
German, It does look like this is a duplicate of ZOOKEEPER-1096. Could you have
a look, please? There is a patch proposed there.

> Project: ZooKeeper
> Issue Type: Bug
> Components: server
> Affects Versions: 3.4.5

> Unlike current ZooKeeper version in trunk intended for release as 3.5.0, the
> current ZooKeeper server version 3.4.5 binds to all ip addresses on the
> specified port for election. It only makes sense to bind to the ip address
> indicated in the configuration file, which is where the other servers will
> connect. Listening to other ip addresses could have bad security implications.
