New page

__TOC__
==Application Details==
*Description: It is an authentication service for creating and validating credentials. It is designed to be highly scalable for use in an HPC cluster environment like Viper.
*Version: 0.5.11
*Module: munge/0.5.11
*Licence: GNU

==Usage Examples==

This module provides the binary for munge and its library component to allow for compilation with external programs.

It allows a process to authenticate the UID and GID of another local or remote process within a group of hosts having common users and groups. These hosts form a security realm that is defined by a shared cryptographic key. Clients within this security realm can create and validate credentials without the use of root privileges, reserved ports, or platform-specific methods.

<pre style="background-color: #000000; color: white; border: 2px solid black; font-family: monospace, sans-serif;">
[username@login01 ~]$ module add munge/0.5.11
</pre>

===Compilation===

A '''C''' code snippet requiring is shown below:

<pre style="background-color: #f5f5dc; color: black; font-family: monospace, sans-serif;">

#define MUNGE_H

#include <sys/types.h>

/*****************************************************************************
* Data Types
*****************************************************************************/

/* MUNGE context opaque data type
*/
typedef struct munge_ctx * munge_ctx_t;

/* MUNGE context options
*/
typedef enum munge_opt {
MUNGE_OPT_CIPHER_TYPE = 0, /* symmetric cipher type (int) */
MUNGE_OPT_MAC_TYPE = 1, /* message auth code type (int) */
MUNGE_OPT_ZIP_TYPE = 2, /* compression type (int) */
MUNGE_OPT_REALM = 3, /* security realm (str) */
MUNGE_OPT_TTL = 4, /* time-to-live (int) */
MUNGE_OPT_ADDR4 = 5, /* src IPv4 addr (struct in_addr) */
MUNGE_OPT_ENCODE_TIME = 6, /* time when cred encoded (time_t) */
MUNGE_OPT_DECODE_TIME = 7, /* time when cred decoded (time_t) */
MUNGE_OPT_SOCKET = 8, /* socket for comm w/ daemon (str) */
MUNGE_OPT_UID_RESTRICTION = 9, /* UID able to decode cred (uid_t) */
MUNGE_OPT_GID_RESTRICTION = 10 /* GID able to decode cred (gid_t) */
} munge_opt_t;

...

</pre>

Compilation is carried out below, in this example the '''gcc''' compiler is used. However, the applies similarly to the Intel compiler too.

Applications written in C/C++ can use the interface provided by <munge.h> and link against '''libmunge'''.

Scripts can invoke the munge and unmunge executables -- specify -h or --help for usage information, or Read The Fine Manpages.

<pre style="background-color: #000000; color: white; border: 2px solid black; font-family: monospace, sans-serif;">

gcc -o makeMUNGE makeMUNGE.c -llibmunge

</pre>
