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.
