MUNGE Uid 'N' Gid Emporium 0.5.6 MUNGE Uid 'N' Gid Emporium is an authentication service for creating and validating credentials. It is designed to be highly scalable for use in an HPC cluster environment. 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. Rationale The need for MUNGE arose out of the HPC cluster environment. Consider the scenario in which a local daemon running on a login node receives a client request and forwards it on to remote daemons running on compute nodes within the cluster. Since the user has already logged on to the login node, the local daemon just needs a reliable means of ascertaining the UID and GID of the client process. Furthermore, the remote daemons need a mechanism to ensure the forwarded authentication data has not been subsequently altered. A common solution to this problem is to use Unix domain sockets to determine the identity of the local client, and then forward this information on to remote hosts via trusted rsh connections. But this presents several new problems. First, there is no portable API for determining the identity of a client over a Unix domain socket. Second, rsh connections must originate from a reserved port; the limited number of reserved ports available on a given host directly limits scalability. Third, root privileges are required in order to bind to a reserved port. Finally, the remote daemons have no means of determining whether the client identity is authentic. Overview A process creates a credential by requesting one from the local MUNGE service. The encoded credential contains the UID and GID of the originating process. This process sends the credential to another process within the security realm as a means of proving its identity. The receiving process validates the credential with the use of its local MUNGE service. The decoded credential provides the receiving process with a reliable means of ascertaining the UID and GID of the originating process. This information can be used for accounting or access control decisions. The contents of the credential (including any optional payload data) are encrypted with a key shared by all munged daemons within the security realm. The integrity of the credential is ensured by a message authentication code (MAC). The credential is valid for a limited time defined by its time-to-live (TTL). The daemon ensures unexpired credentials are not replayed on a particular host. Decoding of a credential can be restricted to a particular user and/or group ID. The payload data can be used for purposes such as embedding the destination's address to ensure the credential is only valid on a specific host. The internal format of the credential is encoded in a platform-independent manner. And the credential itself is base64 encoded to allow it to be transmitted over virtually any transport. What's New in This Release: · A bug was fixed that caused builds using Libgcrypt to fail without the OpenSSL development header files. GPL (GNU General Public License)
Armangil's vodcatcher 1.3.3 Armangil's vodcatcher is a video podcast (or vodcast) client for the command line. Armangil's vodcatcher project provides several download strategies (new shows only, allowed, back-catalog, etc), supports BitTorrent, offers cache management, and generates playlists for video player applications. It is written in Ruby, and runs on Linux (tested), Windows, MacOS and many other operating systems. To watch video podcasts, simply type something like vodcatcher subscriptions.opml > latest.m3u. This will download the subscribed shows into the current directory and generate an M3U playlist named latest.m3u. This application accepts one or more feeds (RSS or Atom) or subscription lists (OPML or iTunes PCAST) as argument, in the form of URLs or filenames. Alternatively, it tries to read one such document from the standard input. For help, use vodcatcher -h. Options: -F, --Function FUNCTION used function (download search ); when using the search function (which generates an OPML document), the only relevant options are -v, -r and -f (default value: download) -d, --dir DIR Query for caching files and storing application state (default value: current directory) -s, --size SIZE Size of media file cache in MB; 0 means infinite; default value is 500 -m, --memsize N Remember last N downloaded media files, and do not download them again; 0 means infinite; default value is 1000 -t, --type TYPE Playlist type (m3u smil pls asx tox xspf ) (default value: m3u) -S, --strategy S Strategy to use for downloading vodcasts (new one back_catalog all cache ): * back_catalog: download any show that has not been downloaded before; prefer the most recent shows of top-most feeds in the OPML/PCAST documents. * new: ignore vodcast back-catalogs; this is like back_catalog, except that only the most recent show of each feed is considered. * one: download one unlistened show of each feed, with a preference for recent shows * all: download all show; even already downloaded shows are downloaded once again. * cache: play shows that are already in cache (default value: new) -f, --feeds N Do not download more than N feeds (when using the download function); or return the first N relevant feeds (when using the search function); 0 means no limits (default value: 1000) -r, --retries N Try downloading files (media, RSS/Atom or or OPML/PCAST) at most N times before giving up (default value: 1) -T, --Torrentdir DIR Copy torrent files to directory DIR; handling torrents through an external BitTorrent client is left to the user; if this option is not used, torrents are handled internally (if RubyTorrent is installed), or else ignored -U, --Uploadrate N Maximum upload rate (kilobytes per second) for the internal BitTorrent client (default: no limit) -i, --itemsize N If a downloaded show is less than N MB in size (where N is an integer), fetch other shows of that same feed until this size is reached (default: 0) -p, --[no-]perfeed Create one subfolder per feed in cache -c, --[no-]cache Play already cached files, DEPRECATED (use -S cache) -e, --[no-]empty Delete all previously downloaded files -a, --[no-]asif Do not download media files (useful for testing) -v, --[no-]verbose Run verbosely --version Display current version -h, --help Show this message Usage examples: vodcatcher -d ~/vodcasts feeds.opml http://host/second.opml > latest.m3u vodcatcher -d ~/vodcasts -S cache > cache.m3u cat feeds.opml \| vodcatcher -d ~/vodcasts > latest.m3u vodcatcher -vd ~/vodcasts -s 500 -m 10_000 -t asx feeds.opml > latest.asx vodcatcher -vF search -f 44 'video vlog' http://www.podfeed.net/opml/directory.opml > results.opml Requirements: · Ruby 1.8.2 or later What's New in This Release: This release includes a major new feature: search. This function generates a subscription list by querying a set of subscription lists/feeds. Here are some usage examples: · the command vodcatcher -F search "rocket tiki video" 'http://www.ipodder.org/discuss/reader$4.opml' > result.opml queries the iPodder podcast directory, and (hopefully) generates a list of video podcasts including Rocketboom and TikiBar TV, · the command vodcatcher -F search -f 22 video http://www.podfeed.net/opml/directory.opml \| vodcatcher > latest.m3u queries Podfeed.net for video podcasts (22 at most), and downloads their latest shows. · The search function can safely be interrupted (through Control-C keystrokes on Linux): it still generates a valid subscription list. · This release also adds support for the XSPF playlist format, and adds the -p option for assigning a separate cache subfolder to each feed.
