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.
