       kup-server - upload server utility


       The  program kup-server is expected to be the receiver of an ssh shell,
       configured   with    the    following    or    similar    options    in

              forwarding,no-pty,no-user-rc,no-X11-forwarding ssh-rsa AAAA[...]

       Each user should have their own UID, as Unix user permissions are  used
       for  specific  tree access control. On the client side, a corresponding
       client-side utility kup is used to initiate the connection and  perform
       the uploads.


       The  configuration  file  for  kup-server  is  located in /etc/kup/kup-
       server.cfg and has the following options:

              All paths in this section should be disjoint. Do not combine any
              of them into one directory.

       data_path = /var/lib/kup/pub
              Path for public consumption, e.g. served via http or rsync.

       git_path = /var/cache/git
              This  is the path where git trees (for the TAR and DIFF options)
              are available.  Those should be readonly for the uploaders.

       lock_file = /run/kup/lock
              A common lock file for data_path.  No program should modify  the
              content  in  data_path  without  holding  an flock on this file.
              Should be readonly for the uploaders.

       tmp_path = /var/cache/kup/tmp/
              tmp_path can be either:

              1. a directory writable by every user and with  the  sticky  bit
              set (typically mode 1777 or 1770).  In that case, DO NOT end the
              path with a slash, or:

              2. A directory containing  an  empty  directory  for  each  user
              (named for that user), owned by that user and mode 0700. In this
              case, DO end the path with a slash.

              In either  case,  this  directory  tree  MUST  be  on  the  same
              filesystem as data_path, since the script expects tocreate files
              in this directory and rename() them into data_path.

       pgp_path = /var/lib/kup/pgp
              A directory containing a GnuPG public  keyring  for  each  user,
              named <user>.gpg and readable (but not writable) by that user.

              All sizes are in bytes, all times in seconds.

       max_data = 8589934592
              Max size of uploaded data.

       bufsiz = 262144
              Buffer size when reading data.

       timeout_command = 30
              How long to wait for a command to time out.

       timeout_data = 300
              Must read at least bufsiz bytes in this timespan.

       timeout_compress = 900
              Uncompressing tarballs must take at most this long.

       timeout_compress_cpu = 900
              Each  compression  command  must  take  at most this long in CPU
