What you quote is true, but I believe you are misunderstanding it. A jail can only have one IP address. However, a system running jails can have as many as you wish. But each jail on the system can only have one IP. > What about localhost? Can two jailed processes (in different jails) connect > to each other using localhost?

You may use those to communicate between them. -- Crist J.
