Protocol Used Between the Director and the File Daemon

A typical conversation might look like the following:

FD: listens
DR: makes connection
DR: Hello <Director-name> calling <password>
FD: 2000 OK Hello
DR: JobId=nnn Authorization=<password>
FD: 2000 OK Job
DR: storage address = <Storage daemon address> port = <port-number>
          name = <DeviceName> mediatype = <MediaType>
FD: 2000 OK storage
DR: include
DR: <directory1>
DR: <directory2>
    ...
DR: Null packet
FD: 2000 OK include
DR: exclude
DR: <directory1>
DR: <directory2>
    ...
DR: Null packet
FD: 2000 OK exclude
DR: full
FD: 2000 OK full
DR: save
FD: 2000 OK save
FD: Attribute record for each file as sent to the
    Storage daemon (described above).
FD: Null packet
FD: <append close responses from Storage daemon>
    e.g.
    3000 OK Volumes = <number of volumes>
    3001 Volume = <volume-id> <start file> <start block>
         <end file> <end block> <volume session-id>
    3002 Volume data = <date/time of last write> <Number bytes written>
         <number errors>
    ... additional Volume / Volume data pairs for volumes 2.. n
FD: Null packet
FD: close socket
