telehack.txt is the main help file for Telehack. You can use it to get hints when you're stuck. Back before Wikis and Google, text files were the only way to learn anything.
Here you can see a copy of the original telehack.txt file (dated 3rd of March, 2012), which can be found in the root directory of every user within the root Telehack system.
Telehack Telehack is a simulation of a stylized arpanet/usenet, circa 1985-1990. It is a full multi-user simulation, including 25,000 hosts and BBS's the early net, thousands of files from the era, a collection of adventure and IF games, a working BASIC interpreter with a library of programs to run, simulated historical users, and more. Connecting ---------- On the web: http://telehack.com/ or open a shell and type telnet telehack.com Telehack.com supports an open web telnet interface. You can also telnet directly to telehack on the standard telnet port 23. Accessibility ------------- Non-sighted users: please type STTY /dumb after connecting to telehack. This will invoke plain terminal mode in the ZRUN games and avoid using ANSI cursor addressing. About this Document ------------------- Telehack is case-insensitive. Commands are often shown in uppercase to distinguish them from surrounding text. Note that you do not need to type commands in all-caps. For example: Type DIR for a list of files You may type DIR or dir to obtain a list of files. In help messages, <> signifies required arguments to commands, whereas  signifies optional arguments. The pipe symbol | signfies "or" or an alternative. For example, send <user|port> [message] means that a user or port must follow the send command, but that the message argument is optional (send will prompt for messages lines if you do not specify one on the command line). @ send forbin hello @ send 15 hello @ send forbin forbin> hello forbin> Getting Help ------------ You can type ? at any prompt to get a list of available commands: @ ? Command, one of the following: acct basic clear daytime dial dir exit files finger halt help hosts ipaddr joke jsr link list log netstat password ping ps ptycon quest rem run send starwars status systat telnet traceroute type uptime usenet users uupath The HELP command provides one-line descriptions of command functions, including any modifier arguments that may be available. Examples: @ help @ help telnet Getting Unstuck --------------- Any command may be terminated by typing ^C (control-C). To log out of a remote host or exit a subshell, type ^D (control-D), EXIT or QUIT. Control Characters ------------------ A control key (CTRL) initiates a number of system functions when it is used in conjunction with another character. To type a control character, hold down the control key, and at the same time press the character you want. For example: to type a CTRL-C, hold down the control key and at the same time press the letter C. In most cases this prints (echoes) on your terminal as ^C. In system documentation, a control character such as control-C may also be described as CTRL-C or ^C. Special control characters: ctrl-C interrupt program ctrl-N next line ctrl-P previous line ctrl-R quick relay (requires backgrounded relay) ctrl-T print system status ctrl-W delete word (up arrow) previous line (next arrow) next line (tab) autocomplete next command/file/user/host Quick Fun --------- Type STARWARS to view the pinnacle of ASCII-mation, a full-length rendition of Star Wars in ASCII. Typing JOKE will display a joke randomly selection from a massive unified historical arpanet/caltech joke database. NLI Lobby --------- When you first connect to Telehack, you will be in the not-logged-in lobby. The NLI lobby is indicated by the '.' prompt: $ telnet telehack.com Trying 126.96.36.199... Connected to telehack.com. Escape character is '^]'. Connected to TELEHACK port 13 It is 8:16 am on Saturday, April 30, 2011 in Mountain View, California, USA. There are 10 local users. There are 24139 hosts on the network. Type ? for a command list. Type HELP for a more detailed command listing. Type control-C to interrupt any command. May the command line live forever. Command, one of the following: acct basic clear daytime exit finger help hosts ipaddr joke list login netstat newuser ping ps run starwars systat telnet traceroute uptime users . A limited subset of commands are available in the lobby. To login or create a new account, type LOGIN. Pager commands -------------- When viewing any paginated output on Telehack, you may receive a --More-- prompt. This may be seen in the commands type, cat, more, less, as well as any command which produces paginated output. At the --More-- prompt, the following single-key commands may be typed: space show next page b back one page q quit g go to top G go to bottom return down one line j up one line k up one line / search for a given string Network Hosts ------------- There are approximately 25,000 virtual hosts on the Telehack network. These represent systems that were on the early Usenet/arpanet as well as defunct BBS systems from the 80's and 90's. Type HOSTS to see a partial list of network hosts. Type HELP HOSTS for more information on the hosts command. A collection of retro files has been distributed across the hosts in the network. The files were sourced from the extensive archive assembled by Jason Scott of Textfiles.com as well as other sources. Telnetting to Hosts ------------------- You may telnet to any host appearing in your netstat list: @ netstat host organization location ---- ------------ -------- sunkist Sun Microsystems Inc.

Hacking a Host -------------- @ dir *.exe porthack.exe wardial.exe @ run porthack [loading PORTHACK into static core] host? mimsy probing MIMSY for open sockets... Once a host has been successfully hacked, you should be able to log into it using your Telehack username and password. Note that hosts which have been hacked and which you can log in to with your username/password are identified in the netstat list with a '*'. Collecting Programs ------------------- Look for .exe programs in the filesystem of each host you visit by typing DIR *.exe or ls *.exe. Use the RUN command to see what the program does. The first time you run a program, it will be added to your static core, and available for running in the future on other hosts, even if the .exe file is not in the local filesystem. You can see what programs have been loaded in your static core with the LIST command: @ list num program ver header --- ------- --- ------ 1. wardial find more hosts 2. porthack open port exploit 3. morrisworm Alert System Command Execution 4. kerntrap Kernel VM Page Table Corrupter 5. rmicrack Deserialization Escalation Exploit 6. trojan Energizer DUO Trojan Scanner 7. metaframe MetaFrame ICA Application Bruteforcer 8. nightstalker Wireless Frame Injector 9. forbin Telnet Login Check Scanner Exploit Type list or list <program> for program details. Type run or run <program> to run a program. Historical Users ---------------- The 25,000 virtual hosts within Telehack were real systems available via modem dialup, fidonet, uucp/usenet, or on the arpanet in the 1980's and 90's. Real people used these systems and could often be seen logged in doing work, reading, socializing or playing games. Data archaeology applied against the oldest available uucp archives, UUCP network maps from the era, as well as other available electronic sources has allowed Telehack to reconstruct the online occupants of these vanished network hosts. To see users logged into a Telehack host, use the FINGER @host command: @ finger @sgi [sgi] Login Name Tty Idle Login Time Office Office Phone vjs Vernon Schryver pts/10 3h Apr 29 06:34 (188.8.131.52) rpw3 Rob Warnock pts/13 6h Apr 25 10:31 (184.108.40.206) vic Victor Mitnick pts/6 1 Apr 28 23:33 (220.127.116.11) greg Greg Chesson pts/9 3 Apr 27 15:05 (18.104.22.168) davidf David Fenstemaker pts/8 2d Apr 24 05:10 (22.214.171.124) cjohnson Chris Johnson pts/12 4h Apr 29 12:21 (126.96.36.199) ian Ian Clements pts/4 6h Apr 23 22:03 (188.8.131.52) baskett Forest Baskett pts/2 29 Apr 27 00:54 (184.108.40.206) pchin Phil Chin pts/7 2h Apr 30 04:31 (220.127.116.11) root Superuser pts/3 1d Apr 28 08:27 (18.104.22.168) artibee Mary Artibee pts/1 3h Apr 23 09:19 (22.214.171.124) wen Wen-ching Chow pts/5 2d Apr 29 04:36 (126.96.36.199) @ finger @chinet [chinet] Login Name Tty Idle Login Time Office Office Phone schneier Bruce Schneier pts/20 3h Apr 26 12:09 (188.8.131.52) randy Randy Suess pts/5 3h Apr 27 17:37 (184.108.40.206) odesta Odesta Corp. pts/27 20 Apr 29 17:34 (220.127.116.11) ward Ward Christensen pts/0 7h Apr 28 06:37 (18.104.22.168) saj Stephen Jacobs pts/8 1h Apr 23 11:59 (22.214.171.124) ... Guessing Passwords ------------------ Users in the past did not always choose strong passwords. A common hacking method was to try various common passwords such as "secret", "love", "trustno1", etc. to find a way into a system. Z-Code Games ------------ A collection of games written for the Z-Machine have been distributed across the hosts in the Telehack network. Z-Code games are identified by the .GAM extension: @ ls *.gam advent.gam lostpig.gam zork.gam @ run advent.gam Welcome to Adventure At End Of Road You are standing at the end of a road before a small brick building.

Remote Terminal Monitoring -------------------------- The link command will connect a remote user's tty to your tty. This will let you assist the remote user by being able to view the remote output. @ link <user or port> In this case, the other user would see something like . %link from port 16 user foo And their session from that point would be mirrored on the linking user's terminal. There is also a separate facility within ptycon to allow simultaneous monitoring of all connected ports. Finger from outside ------------------- Telehack also responds to finger requests from the outside Internet on port 79: $ finger @telehack.com TELEHACK SYSTEM STATUS 04-May-11 23:27:08 4 users port username status last what where ---- -------- ------ ---- ---- ----- 0 operator System Operator 5m console 16 - 3m alice3 Lithuania 17 forbin Dr. Charles Forbin 13m Provo, UT 20 foo Yoda Soda 19m ptycon Oakland, CA $ finger email@example.com USER: forbin system level: WIZARD account age: 95 days last login: today system connects: 5 commands executed: 143 user status bits: HACK10 Hacked 10 network hosts 30-Jan-11 23:19:57 HACK5 Hacked 5 network hosts 30-Jan-11 21:00:34 HACKER Hack the Planet 29-Jan-11 22:31:48 ACCT Registered User 29-Jan-11 22:23:17 $ finger @firstname.lastname@example.org [sgi] Login Name Tty Idle Login Time Office Office Phone vjs Vernon Schryver pts/10 3h May 03 21:26 (126.96.36.199) rpw3 Rob Warnock pts/13 6h Apr 30 01:23 (188.8.131.52) vic Victor Mitnick pts/6 1 May 03 14:25 (184.108.40.206) greg Greg Chesson pts/9 3 May 02 05:57 (220.127.116.11) davidf David Fenstemaker pts/8 2d Apr 28 20:02 (18.104.22.168) cjohnson Chris Johnson pts/12 4h May 04 03:13 (22.214.171.124) ian Ian Clements pts/4 6h Apr 28 12:55 (126.96.36.199) baskett Forest Baskett pts/2 29 May 01 15:46 (188.8.131.52) pchin Phil Chin pts/7 2h May 04 19:23 (184.108.40.206) root Superuser pts/3 1d May 02 23:19 (220.127.116.11) artibee Mary Artibee pts/1 3h Apr 28 00:11 (18.104.22.168) wen Wen-ching Chow pts/5 2d May 03 19:28 (22.214.171.124) Usenet Archive -------------- Type USENET to view the Usenet archive. The archive was originally collected by Henry Spencer at the University of Toronto beginning in 1981. Later it was rescued by David G. Wiseman from the University of Western Ontario, who drove two hours in a pickup truck to collect 141 magtapes and save them from destruction: If I recall correctly, the issue of Henry Spencer's (actually, the University of Toronto, Department of Zoology's) NetNews archive was raised at a Usenix conference in the early 90's. The question: can we get at them? Bruce Jones was especially interested in this. Henry's answer was that it really wasn't going to be easy because he had neither the disk space nor the tape drive to pull them all down to make them available. I, it turned out, did. So one bright winter day I drove from London (Ontario Canada) to Toronto (Ontario Canada) -- a two hour drive in my shiny new pickup truck and picked up 141 magtapes from the Zoology department at UofT and brought them back to the Department of Computer Science at the University of Western Ontario. (A not unimpressive bandwidth, by the way, of some 18Mb/sec :-) never underestimate the bandwidth of a pickup truck on the highway ) -- http://www.csd.uwo.ca/staff/magi/personal/usenet.html Some additions have been made to the usenet archive available on Telehack which have been provided from other sources. Halt ---- Halting the CPU to enter the system monitor is not advised. However, if you do this, the operator will usually supply a monitor entry point to enable CPU restart and re-entry into the telehack exec. Shortcuts --------- . repeat last command w systat w finger l dir ls dir date daytime cat type cls clear ? command list How to enable telnet in Windows 7 --------------------------------- Windows 7 ships with a telnet client, but it is shut off by default. To enable it, do the following: Start Control Panel Programs And Features Turn Windows features on or off Check Telnet Client Hit OK After that, you can open a command prompt and type telnet telehack.com See Also -------- http://telehack.wikia.com http://twitter.com/telehack http://xkcd.com/138/ http://walyou.com/telehack/ http://waxy.org/2011/06/playable_archaeology_an_interview_with_the_telehacks_anonymous_creator/ http://www.techradar.com/news/networking/hack-virtual-1980s-networks-with-telehack-1035135 http://news.ycombinator.com/item?id=2620552 EOF --- http://www.youtube.com/watch?v=Y6ljFaKRTrI
