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.
