NAME

   remunge - MUNGE credential benchmark

SYNOPSIS

   remunge [OPTION]...

DESCRIPTION

   The  remunge  program benchmarks the performance of MUNGE.  A benchmark
   runs for the specified  duration  or  until  the  specified  number  of
   credentials  are  processed, whichever comes first.  At its conclusion,
   the number of credentials processed per second is written to stdout.

   By default, credentials are encoded  for  one  second  using  a  single
   thread.

OPTIONS

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

   -L, --license
          Display license information.

   -V, --version
          Display version information.

   -q, --quiet
          Display  only  the creds/sec numeric result.  This is useful for
          producing input files for ministat.

   -c, --cipher string
          Specify the cipher type, either by name or number.

   -C, --list-ciphers
          Display a list of supported cipher types.

   -m, --mac string
          Specify the MAC type, either by name or number.

   -M, --list-macs
          Display a list of supported MAC types.

   -z, --zip string
          Specify the compression type, either by name or number.

   -Z, --list-zips
          Display a list of supported compression types.

   -e, --encode
          Encode (but do not decode) each credential.   By  bypassing  the
          decode  operation,  the  credential  is not stored in the replay
          cache.

   -d, --decode
          Encode and decode each credential.

   -l, --length integer
          Specify an arbitrary payload length (in bytes).  The integer may
          be   followed   by  a  single-character  modifier:  k=kilobytes,
          m=megabytes, g=gigabytes; K=kibibytes, M=mebibytes, G=gibibytes.

   -u, --restrict-uid uid
          Specify the user name or UID allowed to decode  the  credential.
          This  will  be  matched  against  the  effective  user ID of the
          process requesting the credential decode.

   -g, --restrict-gid gid
          Specify the group name or GID allowed to decode the  credential.
          This  will  be  matched  against  the  effective group ID of the
          process requesting  the  credential  decode,  as  well  as  each
          supplementary  group  of  which  the  effective  user ID of that
          process is a member.

   -t, --ttl integer
          Specify the time-to-live (in seconds).  This controls  how  long
          the  credential is valid once it has been encoded.  A value of 0
          selects the default TTL.  A value  of  -1  selects  the  maximum
          allowed TTL.

   -S, --socket path
          Specify the local domain socket for connecting with munged.

   -D, --duration integer
          Specify the test duration (in seconds).  The default duration is
          one second.  A value of -1 selects the  maximum  duration.   The
          integer   may   be  followed  by  a  single-character  modifier:
          s=seconds, m=minutes, h=hours, d=days.

   -N, --num-creds integer
          Specify the number of credentials to generate.  The integer  may
          be   followed   by  a  single-character  modifier:  k=kilobytes,
          m=megabytes, g=gigabytes; K=kibibytes, M=mebibytes, G=gibibytes.

   -T, --num-threads integer
          Specify  the  number  of  threads  to   spawn   for   processing
          credentials.

   -W, --warn-time integer
          Specify  the  maximum  number  of  seconds  to allow for a given
          munge_encode() or  munge_decode()  operation  before  issuing  a
          warning.

EXIT STATUS

   The  remunge  program  returns  a  zero  exit  code  if  the  benchmark
   completes.  On error, it prints an error message to stderr and  returns
   a non-zero exit code.
