By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

No piece checking or downloading is performed. + This option is normally used alone. + + +-c Check pieces only, don't download + + Hash-checks all pieces of the torrent to verify completion + status and exits. Use this when you want to verify that you've + successfully downloaded the complete torrent, or to make sure + the files are intact after a system crash. This option is + normally used alone, but can be used with -X for an automated + completion check. + + +-v Verbose output (for debugging) + + Generates [a lot of] extra output while CTorrrent is running. + ___________________________________ + + Downloading Options + + +-e int Exit while seed <int> hours later (default 72 hours) + + Indicate how long (in hours) you want to "seed" (continue + uploading) after download has completed. It is considered + polite and fair (and required by some tracker sites) to seed + for some time after downloading. + + +-E num Exit after seeding to <num> ratio (UL:DL) + + Specify a desired "seed ratio". After downloading completes, + the client will continue seeding (uploading) until your total + upload volume divided by your download volume equals this + number. Fractional values (such as 1.5) are allowed. It is + considered polite and fair (and required by some tracker sites) + to seed until your ratio is at least 1:1. + + +-i ip Listen for connections on specific IP address (default all/any) + + Specify the IP address on which you want to listen for incoming + connections. This is only useful if your system has multiple + network interfaces and you want to restrict access or run + multiple clients on different interfaces. + + +-p port Listen port (default 2706 -> 2106) + + Specify the TCP port number on which to listen for incoming + connections. By default, CheaTorrent starts at 2706 and searches + for an available port in decreasing order until it finds one or + exhausts all ports down through 2106. The behavior with this + option is similar, but starting at the specified port number. + + +-I ip Specify public/external IP address for peer connections + + Specify the IP address which the tracker should give out to + peer clients in order to connect to you. This is normally + needed only if you are behind a NAT and on the tracker's local + network. + + +-u num or URL Alternate announce (tracker) URL + + Specify an alternate tracker announce URL. The parameter can be + the actual URL or the number from the list of alternates + printed when starting the client or using -x. + + +-s filename Download ("save as") to a different file or directory + + Download to a different filename or top-level directory name + than what is given in the metainfo file. + + +-C cache_size Cache size, unit MB (default 16MB) + + Specify the maximum amount of memory to use for caching + downloaded slices. The program may use less than this; the + cache size is dynamically tuned based on the download and + upload rates. You may need to use this option if running on a + memory-constrained system such as a router or SAN device. If + you use a value of 0, no memory cache will be used but the + process will be more disk-intensive. + + +-f Force saved bitfield or seed mode (skip hash check at startup) + + Perform a fast startup by skipping the initial (or background) + hash verification of the files. This option is not generally + recommended since the client now performs initial hash checking + in the background. Use this option only if CheaTorrent was shut + down cleanly when last downloading this torrent and you are + absolutely certain that the bitfield (if download is not + complete) and data files are intact and correct. To emulate the + old behavior of hash-checking all pieces before beginning + download or seeding, use -f along with the -c option. + + +-b filename Specify bitfield save file (default is torrent+".bf") + + Piece completion status is saved to a bitfield file on exit if + download has not completed. On startup the file is read to + determine (and check) available pieces. The -b option can be + used to specify a filename other than the default. Be + consistent and careful with this option; it is generally not + needed. + + +-M max_peers Max peers count (default 100) + + Set the maximum allowable number of peer connections. If this + number is reached, no new connections will be initiated or + accepted. If memory or upload bandwidth are constrained, you + may want to use this option to specify a lower value. + + +-m min_peers Min peers count (default 1) + + Set the desired minimum number of peer connections. If the + number falls below this value, the client will contact the + tracker to request more peers. + + +-z slice_size Download slice/block size, unit KB (default 16, max 128) + + Sets the size of the basic unit of download. For greatest + compatibility with other peer clients, use the default. This + value can also affect the precision with which bandwidth is + managed. + + +-n file_list Specify file number(s) to download + + Specify a priority order for downloading files in the torrent. + A comma-separated list of file numbers and groups can be + specified; the file numbers can be seen with the -x option. The + client will preferentially request pieces of the + highest-priority files, requesting a piece from a + lower-priority group if a peer has no such pieces. + A group may consist of: + + + a file number + + a range of file numbers (x-y) + + a combination of file numbers and ranges separated with plus + (+) signs + + an asterisk (*) or 3-dot ellipsis (...) + + If an asterisk (remember to quote it on the command line!) or + ellipsis is used, the client will download and seed the + remainder of the torrent once the prioritized files are + completed; this is similar to the previous behavior of the + option. If no such specification is given, the client will + download and seed only the indicated files. + Examples: + + -n 3 + Download and seed only file 3. + + -n 3+5+7,8-11 + Download files 3, 5, and 7 simultaneously, then download + files 8 through 11 simultaneously, then stop downloading + and seed all downloaded files. + + -n 3-4,... + Download files 3 and 4 simultaneously, then download and + seed all remaining content. + + +-D rate Max bandwidth down (unit KB/s) + + Specify a download bandwidth limit for this torrent. The client + will maintain its short-term average download rate at or below + this value. + + +-U rate Max bandwidth up (unit KB/s) + + Specify an upload bandwidth limit for this torrent. The client + will maintain its short-term average upload rate at or below + this value. + + +-P peer_id Set Peer ID prefix. (default "-CD0301-") + + Specify an alternate peer ID prefix. This can be useful if a + tracker is set up to only allow client programs that it + recognizes. (The admin may not even realize it, so you may want + to try contacting them to request that they change their + configuration or add Enhanced CheaTorrent to the list.) If you + receive a tracker warning message that your client is out of + date, try using this option with the prefix of another + well-known client program (such as "-AZ2304-"). + + +-A user_agent Set User-Agent header. (default "Enhanced-CheaTorrent/dnh3.1") + + Specify an alternate user-agent header. This can be useful if a + tracker is set up to only allow client programs that it + recognizes. + + +-S host:port Use CTCS server at host:port + + Maintain a connection to CTCS for status reporting, bandwidth + control, and client management. Using a colon at the end of the + parameter (as in "-S localhost:2780:") will cause the client to + prompt for a password to send to CTCS when connecting. + + +-a Preallocate files on disk + + Use this if you are concerned about file fragmentation or + out-of-order block storage. This option is only effective when + initially creating the files and will cause startup to take + longer as each entire file is written in order to reserve + physical disk space. Note that all files will be created and + preallocated even if the "-n" option is used to download a + particular file. + + +-T Convert foreign filenames to printable text + + Substitutes a hex representation of any non-printable + characters in filenames; an underscore will be inserted between + any such sequences and regular text. This applies to printing + the name of the file as well as accessing it on disk, so you + need to use it (or not) consistently across multiple runs of + the same torrent. It does not apply to names specified with the + "-s" option. + + +-X command Run command upon download completion ("user exit") + + Specifies a "user exit" command to run upon download + completion. The string parameter will be passed to the sh shell + for execution; see the system() man page for further + clarification. You will need to quote this string on the + command line in order to identify it as a single parameter and + prevent special characters from being interpreted. Some + substitution sequences beginning with ampersand (&) are + available; note that it's a good idea to quote the sequence + within the string so that the substituted names will be quoted + in the final command. + + + &d will be replaced by the name of the directory or filename + that contains the downloaded data. + + &t will be replaced by the name of the torrent metainfo file + (with path, if it was specified that way to cheatorrent). + + &w will be replaced by the client's working directory. + + Note that the fork() and system() system/library functions are + used for best portability. As a result, significant extra + memory may be used while the specified command is running. Be + advised to use this feature as a trigger mechanism to update a + file or run a short script that kicks off a background task + rather than for executing a longer task directly. + This option can also be used together with -c as an automated + completion check. Normally the completion command will be run + only if data has been downloaded; this case is the exception. + + +-d Daemon mode (fork to background) + + The client will detach itself from the terminal session and + become a background process, closing stdin, stdout, and stderr. + There is no way to bring it back into the foreground of a + session later; if you want to monitor or manage the client then + either use the CTCS option (-S) as well or run the client under + [46]screen instead of using -d. + If this option is specified twice (-dd) then redirected + standard I/O descriptors will not be closed. + ___________________________________ + + Options for Creating a New Torrent + + +-t Create a new torrent file + + Indicates that you want to create a new torrent. This must be + the first option specified when creating a torrent. + + +-s filename Specify metainfo file name + + (Required) Give the name of the file to be created. + + +-u URL Tracker's URL + + (Required) Specify the tracker's announce URL. This usually + looks similar to "http://tracker.example.com:port/announce". + + +-l piece_len Piece length (default 262144) + + Specify the piece size for your torrent. This will also + determine the number of pieces in the torrent. + + +-p Private (disable peer exchange) + + Disable the use of DHT, PEX, or other trackerless peer-exchange + methods by other clients when sharing this torrent. + + +-c comment Include a comment/description + + Include a comment field in the torrent file. + _________________________________________________________________ + + Examples + + List the contents of a torrent: + +cheatorrent -x example.torrent + + Verify download completion status (takes a little time): + +cheatorrent -c example.torrent + + Download or seed a torrent using default options: + +cheatorrent example.torrent + + Download with a limit of 100KB/s, upload limit of 10KB/s, and seed + until a ratio of 1.5:1 is achieved: + +cheatorrent -D 100 -U 10 -E 1.5 example.torrent + + Create a torrent: + +cheatorrent -t -u "http://tracker.example.com:6969/announce" -s example.torrent fi +le_or_dir_to_upload + _________________________________________________________________ + + Runtime Commands + + Several commands are available during upload/download; a list is + available by pressing ? or h: +Available commands: + [Esc/0] Operator menu m[+/-] Adjust min peers count + d[+/-] Adjust download limit M[+/-] Adjust max peers count + u[+/-] Adjust upload limit C[+/-] Adjust max cache size + n Download specific file S Set/change CTCS server + e[+/-] Adjust seed exit time v Toggle verbose mode + E[+/-] Adjust seed exit ratio Q Quit + X Completion command + + Command keys are case-sensitive. When a command key is pressed, a + prompt or current value is displayed. Prompts will suspend display of + the status line while waiting for input, though the client continues + to run normally.

Note that the bandwidth limit commands use the same letters + but opposite case. + + Operator Menu + + The 0 or Esc command key displays an operator menu with more advanced + (or less routine) options.

Of particular + use is the debug/verbose channel, which can be directed to a file to + create a debug log (be sure to also enable verbose output with the "v" + command key or CTCS). + + The second set of options is used to select the status line format. + Since the actual client status is used to generate the menu options, + the operator menu display can also be used just to view the alternate + status information. An asterisk (*) indicates the currently selected + format. + + The next two options provide a means to view more detailed current + status and statistics or to pause uploading and downloading (more or + less immediately, unlike the previous CTCS pause function). + + Note that there is no "recovery" from daemon mode. Use CTCS (with + daemon mode) and/or "screen" if you want the client to run in the + background but need to manage or monitor it. + + The next two options are the same as the corresponding actions in + CTCS. The first performs an early tracker update. The second restarts + the tracker session as if you had exited and restarted the client. + This can be used to recover if the tracker appears to have suffered a + failure and does not recognize your client session. + _________________________________________________________________ + + Usage Notes + + Bandwidth Limits + + You should always specify an upload bandwidth limit. With the most + recent changes in the program, this "option" is not just a limit to + stay under, but an advisement to the client as well. Enhanced CheaTorrent + now tunes its upload performance based on the limit. Without a limit, + the client has no idea how much bandwidth your line can support and so + cannot perform this tuning. It is now possible to achieve better + upload rates with a limit than without. Due to the tit-for-tat nature + of bittorrent, this can also indirectly increase your download + performance. If you just want the client to use as much upload + bandwidth as possible, then choose a limit that is 10% or so less than + the available upload capacity of your line. ("Available" means not + typically in use by other applications.) + + Note that limits are specified in KB/s (kilobytes per second), where + 1KB = 1024 bytes (8192 bits). Your ISP likely measures in "kilobits" + (Kb, where 1Kb = 1000 bits or 125 bytes) or "megabits" (1Mb = 1000000 + bits or 122KB). Some of that [to the tune of 20% in some cases] is + used by the line protocol and thus not available to you at all. + + Startup + + If you have previously started the torrent, CheaTorrent will perform a + hash-check of all pieces (or pieces indicated by the bitfield file if + present) while beginning the upload/download process. This does not + mean that it is starting over--quite the opposite! This is how the + client determines which pieces it already has so that they will not be + downloaded again (and can be offered for uploading). This process + confirms the pieces that you have even if the files have been altered + or recovered after a system crash. + + Status Line + + The status line that is output by the client has changed since the + original and deserves some explanation. + + / 0/33/110 [672/672] 0MB,1130MB | 0,20K/s | 0,0K P:4/10 + - - -- --- --- --- --- ------ - -- - - ---- + A B C D E F H I J K L M P + + A: Ticker; this character changes to indicate that the client is + running. + B: Number of seeders (complete peers) to which you are connected. + C: Number of leechers (incomplete peers) to which you are connected. + D: Total number of peers in the swarm, as last reported by the + tracker. + E: Number of pieces of the torrent that you have completed. + F: Total number of pieces in the torrent. + peers. + H: Total amount of data you have downloaded. + I: Total amount of data you have uploaded. + J: Your current download rate (20 second average). + K: Your current upload rate (20 second average). + L: Amount of data downloaded since the last status line update. + M: Amount of data uploaded since the last status line update. + P: Completion ratio of current fileset (when -n is used). + + Additional information such as tracker connection status may be + displayed at the end of the status line when appropriate. + + Alternate Status Line + + A new status line format is also available via the operator menu. + + / S:4/8 L:4/5 C:1 R=5.85 D=42 U=16 K/s 79/100% 49:47 P:40/100% 2:41 + - - - - - - ---- -- -- -- ---- ----- ------- ---- + A B C D E F G H I J K L M N + + A: Ticker; this character changes to indicate that the client is + running. + B: Number of seeders (complete peers) to which you are connected. + C: Number of seeders in the swarm (excluding yourself), as last + reported by the tracker. + D: Number of leechers (incomplete peers) to which you are connected. + E: Number of leechers in the swarm (excluding yourself), as last + reported by the tracker. + F: Number of peer connection attempts in progress. + G: Your upload/download ratio. + H: Your current download rate (20 second average). + I: Your current upload rate (20 second average). + J: Percent of the torrent that you have completed. + K: Percent of the torrent currently available from you and your + connected peers. + If you have the complete torrent, "seeding" is displayed instead + of these percentages. + L: Estimated download or seed time remaining, in hours and minutes. + M: Completion and availability of current fileset (when -n is used). + N: Time remaining to complete the current fileset (when -n is used). + + Additional information such as tracker connection status may be + displayed at the end of the status line when appropriate. + + Stopping CheaTorrent + + Besides the Q command key (equivalent to Ctrl-C but a nicer user + interface), CheaTorrent can be stopped before completing download or + seeding by pressing Ctrl-C or sending the TERM signal ("kill pid"). + This will tell the client to contact the tracker to send its final + statistics and advise that it is leaving the torrent. Note that this + could take a couple of minutes if the tracker is down or very busy. + (Only one attempt is made, so the client will exit even if the + connection fails.) + + If Ctrl-C or kill is used a second time, the client closes all peer + connections and exits without waiting for the tracker connection. This + means that other peers may still attempt to contact you for a while, + and the tracker may not accept you back into the torrent until your + original session expires. (This could take up to a couple of hours, + depending on the tracker.) + + In either case, this is a clean shutdown of CheaTorrent. All downloaded + data is written to disk before exiting. (Though only complete pieces + really count if the torrent is restarted, as there is no way to know + which blocks are missing from partial pieces.) + _________________________________________________________________ + diff --git a/aclocal.m4 b/aclocal.m4 new file mode 100644 index 0000000..64fd963 --- a/dev/null +++ b/aclocal.m4 @@ -0,0 +1,1020 @@ +# generated automatically by aclocal 1.9.1 -*- Autoconf -*- + +# Copyright (C) 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003, 2004 +# Free Software Foundation, Inc. +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +# -*- Autoconf -*- +# Copyright (C) 2002, 2003 Free Software Foundation, Inc. +# Generated from amversion.in; do not edit by hand. + +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 2, or (at your option) +# any later version. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
