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.
- -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.
