ctcs-1.4.1.tar.gz_6K4_ctcs protocol_remote

Note, this document is a text transcription of the web page at http://www.rahul.net/dholmes/ctorrent/ctcs.html. It will be much easier to read the sample display tables there than below. ______________________________________________________________________ CTorrent Control Server CTorrent Control Server (CTCS) is an interface for monitoring and managing [1]Enhanced CTorrent clients. It can manage allocation of bandwidth, provide status information, and allow changes to the running configuration of each client. Communication with CTorrent is via a TCP connection, and the user interface is a web browser. The current version is implemented in [2]Perl since that was used to develop the original prototype. It may be reimplemented in C at some later date, but the Perl version is fully functional. You will need to install a Perl interpreter if your system does not already have one.

All new files will be available there for convenient downloading from a mirror site near to you. [10]ctcs-1.4.1.tar.gz: CTCS version 1.4.1. List of changes: * Additional color-coding of peer interested/choked status * Fixed error displaying Torrent Details screen when a file has zero size. * Fixed problems handling POST form input. * Boost client's limit only if bandwidth is shared. * On details screen for terminated torrent, Torrent table showed "Start Time". [11]ctcs-1.4.tar.gz: CTCS version 1.4. List of changes: * Protocol 3 support + Auto-configuration of client configuration options + File download priority + Updated block start messages for consistency * New client configuration options as provided by client version 3.1 and later. * Each file's download priority is shown in the list and can be set as an alternative method to changning the "-n" option value. [12]ctcs-1.3.tar.gz: CTCS version 1.3. List of changes: * Protocol 2 support + Cache size configuration option + Removal of option to exit when peers=0 + Total seeders & leechers in the swarm, and connecting peers, are shown. + File availability is shown. * Bandwidth management changes + Works correctly with Enhanced CTorrent dnh3 + Adjusted the threshold for increasing a limit + Wait a few minutes after a client becomes seed to reduce the download limit. This allows duplicate slices still "in flight" to be received and thus cleared from the connection. + The average bandwidth available per client is now regarded as an implied minimum. A client limit will generally not be reduced below this value, though unused bandwidth will be allocated to other clients. This avoids a slow and difficult ramp-up period when an idle client suddenly acquires an active peer. * Cosmetic updates + Configuration values are highlighted at certain times for visibility or attention. + Zero peer rates and transfer amounts are not shown, for clarity. + Peer completeness is shaded red by value (0%=red, 100%=white). + Uninterested states are indicated in gray. + Peer IP address is centered in the cell. + Peer transfer rates and totals are shaded purple by scale (B/K/M). [13]ctcs-1.2.tar.gz: CTCS version 1.2. List of changes: * Version number is now displayed at bottom of main page. * Added a few client ID strings. * The maximum limit "boost" value is now based on the global limit and number of torrents. Previously it was always 1K; now it will be less if bandwidth is constrained. * Improved handling of minimum limits. Now a torrent's limit will never be reduced below its minimum, but unused bandwidth will still be borrowed for other torrents. This is more stable with the new seeding algorithm. * Eliminated the checkboxes to change current limits on the Advanced Limits screen. Each limit is changed only if a new value is entered for it. * Added an option to limit a torrent's max upload rate based on share ratio. (See the Advanced Limits screen.) * In the Advanced Limits screen, options related to downloading are now disabled for torrents that are seeding. * Message indication: An exclamation point (!) is shown next to the torrent title if messages are present. The torrent title is highlighted based on message severity. * Messages that include a severity (added in dnh2.2) will be highlighted in red (sev 1) or yellow (sev 2). Sev 3 and no-severity (pre-dnh2.2) messages are not highlighted. * Enabled a Torrent Details page for terminated torrents. * Avoid crashing if a user stops/reloads too quickly. Resolved with a SIGPIPE handler, which may not work on all platforms. If you know how to handle this situation on your platform, please let me know. I found that checking the return code from print/printf was not particularly reliable. * If the hostname is unresolvable, the program will now fall back to "localhost" or 127.0.0.1. Previously this could result in an error. * Cleaned up HTML print statements (code formatting). [14]ctcs-1.1.tar.gz: CTCS version 1.1. List of changes: * Use "\r\n" as newline. * Added a few client ID strings. * Fixed data sending (user interaction) on Linux. * Fixed error when all upload or download limits are zero. [15]ctcs-1.0a.tar.gz: CTCS version 1.0a [16]ctcs-1.0a.diff: Patch file for 1.0 There was a minor bug in the original release that prevented the Messages feature from working (messages were discarded). If you previously downloaded version 1.0, please apply this small patch to enable the feature. _________________________________________________________________ Usage ctcs [-d <dlimit>] [-u <ulimit>] [-i <interval>] [-p <port>] [-P] -d dlimit Overall download bandwidth limit, in KB/s (default 100). -u ulimit Overall upload bandwidth limit, in KB/s (default 25). Use a value that is less than the maximum capacity of your network line. -i interval Bandwidth management change interval, in seconds (default 5). The recommended minimum value is 3. Higher values will reduce oscillation of individual torrent limits, but a value that is too high will cause very slow reactions to changes in bandwidth usage. -p port The TCP port on which to listen for connections (default 2780). -P Prompt for an authorization password. If your system does not have perl available at /usr/bin/perl, you will need to change the path in the first line of the file. To connect Enhanced CTorrent (release dnh2 or later) clients to CTCS, use the "-S" command-line option, e.g. "-S localhost:2780". To use a web browser to view or change status, enter the same host and port as the location, e.g. "http://localhost:2780/". Security Though there is a basic option, security is very minimal. Running CTCS on a computer or network with untrusted users is not recommended. It should go without saying that the CTCS listening port should not be made openly accessible from the public Internet (but there, it's said anyway). The "-P" option will cause CTCS to prompt for
