MUNGEKEY(8) MUNGE Uid 'N' Gid Emporium MUNGEKEY(8) 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 us- ing 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 /usr/local/etc/munge/munge.key Contains the shared cryptographic key for hosts within the security realm.
