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).

Enable this authentication method.
 -b, --background
Run as daemon.
-B, --pid-file=<file>
Write PID to file.
 -C, --no-core-dump
Do not create a core dump, even due to a crash.
-c, --challenge-dir=<dir>
Challenge directory for unix filesystem authentication.
-d, --debug=<flag>
Enable debugging for this sybsystem
 -E, --parent-death
Exit if parent process dies.
-e, --parent-check=<time>

-n, --catalog-name=<name>
Use this name when reporting to the catalog.
-o, --debug-file=<file>

-Q, --root-quota=<size>
Enforce this root quota in software.
 -R, --read-only
Read-only mode.
-r, --root=<url>
URL of storage directory, like file://path or hdfs://host:port/path.
-s, --stalled=<time>

-T, --group-cache-exp=<time>
Maximum time to cache group information. (default is 900s)
-t, --idle-clients=<time>
Disconnect idle clients after this time. (default is 60s)
-U, --catalog-update=<time>
Send status updates at this interval. (default is 5m)
-u, --advertize=<host>
Send status updates to this host. (default is catalog.cse.nd.edu)
 -v, --version
Show version info.
-W, --passwd=<file>
Use alternate password file for unix authentication
-w, --owner=<name>
The name of this server's owner. (default is username)
-y, --transient=<dir>
Location of transient data (default is pwd).
-Z, --port-file=<file>
Select port at random and write it to this file. (default is disabled)
-z, --unix-timeout=<time>
Set max timeout for unix filesystem authentication. (default is 5s)

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:
