Man 8 mungekey

Name

mungekey -- MUNGE key management utility

Synopsis

mungekey [-c] [-b bits] [-f] [-k keyfile] [-v]

Description

The mungekey executable is the key management utility for MUNGE. It should be run by the same user that starts the munged daemon.

If no options are specified, mungekey will attempt to create a new key using the default settings; this will fail if the keyfile already exists.

All munged daemons within a security realm must use the same key. In other words, all hosts within an administrative group (or cluster) using MUNGE for authentication must use the same key; this keyfile can be created on one host and then securely copied to all other hosts.

Options

• -b, --bits integer
  Specify the number of bits in the key being created [256-8192].

• -c, --create
  Create a new keyfile.

• -f, --force
  Force the keyfile to be overwritten if it already exists.

• -h, --help
  Display a summary of the command-line options.

• -k, --keyfile path
  Specify the keyfile pathname.

• -L, --license
  Display license information.

• -v, --verbose
  Be verbose.

• -V, --version
  Display version information.

Files

• $(sysconfdir)/munge/munge.key
  Contains the shared cryptographic key for hosts within the security realm.
