NAME

       chirp_server - create a Chirp user-level filesystem

SYNOPSIS

       chirp_server [options]

DESCRIPTION

       Starts a Chirp server which allows the sharing of data with friends and colleagues without
       requiring any administrator privileges.  Chirp provides an  RPC  network  interface  to  a
       "backend" filesystem which can be the local filesystem or even the Hadoop HDFS filesystem.
       Chirp supports flexible and robust ACL management of data.

       For    complete    details    with    examples,    see    the    Chirp    User's    Manual
       (http://ccl.cse.nd.edu/software/manuals/chirp.html).

              Send status updates at this interval. (default is 5m)

       -u, --advertize=<host>
              Send status updates to this host. (default is catalog.cse.nd.edu)

ENVIRONMENT VARIABLES

       •   CATALOG_HOST Hostname of catalog server (same as -u).

       •   TCP_LOW_PORT Inclusive low port in range used with -Z.

       •   TCP_HIGH_PORT Inclusive high port in range used with -Z.

EXIT STATUS

       On success, returns zero.  On failure, returns non-zero.

EXAMPLES

       To start a Chirp server with a local root directory:

               % chirp_server -r file:///tmp/foo

       Setting various authentication modes:

               % chirp_server -a hostname -a unix -a ticket -r file:///tmp/foo
