REMUNGE(1) MUNGE Uid 'N' Gid Emporium REMUNGE(1) 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 creden- tials 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 pro- ducing 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 bytes 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 re- questing 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 seconds 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 socket for connecting with munged. -D, --duration seconds 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=min- utes, 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 seconds Specify the maximum number of seconds to allow for a given munge_en- code() 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.
