NAME

SYNOPSIS

11       mungekey [-c] [-b bits] [-f] [-k keyfile] [-v]
12

DESCRIPTION

15       The  mungekey  executable  is the key management utility for MUNGE.  It
16       should be run by the same user that starts the munged daemon.
17
18       If no options are specified, mungekey will attempt to create a new  key
19       using  the  default settings; this will fail if the keyfile already ex‐
20       ists.
21
22       All munged daemons within a security realm must use the same  key.   In
23       other  words, all hosts within an administrative group (or cluster) us‐
24       ing MUNGE for authentication must use the same key; this keyfile can be
25       created on one host and then securely copied to all other hosts.
