NAME

munge - MUNGE credential encoder

 

SYNOPSIS

munge [OPTION]...

 

DESCRIPTION

The munge program creates an MUNGE credential containing the UID and GID of the calling process. Additional payload data can be encapsulated in as well. The returned credential can be passed to another process which can validate its contents (e.g., via the unmunge program). This allows an unrelated and potentially remote process to ascertain the identity of the calling process.

By default, payload input is read from stdin and the credential is written to stdout.

 

OPTIONS

-h, --help
Display a summary of the command-line options.
-L, --license
Display license information.
-V, --version
Display version information.
-n, --no-input
Discard all input for the payload.
-s, --string string
Input payload from the specified string.
-i, --input file
Input payload from the specified file.
-o, --output file
Output the credential to the specified file.
-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.
-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.

 

EXIT STATUS

The munge program returns a zero exit code when the credential is successfully created and returned. On error, it prints an error message to stderr and returns a non-zero exit code.
