Comment (by cypherpunks):

 @n00b
 The exit node will try to resolve your hostname via DNS. If your hostname
 is something generic like "localhost", "ubuntu", "debian", ... that's not
 an issue. If it's something unique, that's quite bad.

 Another socksification method won't help (I don't think there is any that
 filters out DNS requests for the local hostname). Use a generic hostname
 like "localhost" and make sure to use an empty domain name or something
 generic like "localdomain".

 "hostname --fqdn" will show your hostname + domain.
