passive+active connections and fxp+glftpd
I have two questions.
First of, can someone explain the concept of passive and active connections to me? I have a feeling this might be the thing that makes it ******* impossible to fxp to and from my server, and this brings us to my second question: I need help setting up my glftpd to allow fxp. Do I need to configure pasv_addr or what? Can anyone give me an example on what such a setting would look like? Eg. user "A" who connects to me on ip X wants to fxp something from server "1" with ip Y to my server which has ip Z. How do I set this up properly in the glftpd.conf?
