Telnet hacking,to remote any computer in world

Posted by


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
from 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.

On the web:

or open a shell and type

telnet supports an open web telnet interface. You can also telnet
directly to telehack on the regular telnet port of 23.

The following ports are also open for those, who have issues connecting:
443, 1337, 8080, 31173 (e.g. ‘telnet 443’)


Non-sighted users: please type STTY /dumb after connecting to telehack.
This will invoke plain terminal mode in the Z-code 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
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

The HELP command provides one-line descriptions of command functions,
including any modifier arguments that may be available. Examples:

@ help
@ help telnet
@ help ftp
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 Trying… Connected
to 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 down 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 as well as other sources.
Telnetting to Hosts

You may telnet to any host appearing in your netstat list:

@ netstat

WARNING: You must have prior authorization to access this system.
All connections are logged and monitored. By connecting to
to this system you fully consent to all monitoring.
Unauthorized access or use will be prosecuted to the full
extent of the law.


If you have not yet hacked into a host, you can try to login as the guest
user. The full set of commands on the host may not be available if you are
logged in as guest.
Hacking a Host

@ dir *.exe
porthack.exe wardial.exe
@ porthack
[run porthack.exe]
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 and Moving Programs

DIR *.exe or ls *.exe. You will be able to transfer programs between hosts
using the FTP command. On each host, a dedicated part of the disk has been
made available to you, in which you can store these programs.

Be careful not to overfill it, check your disk usage with the DF command
before transferring a file.

Example of an FTP session:

is1$ ftp uunet
Connected to uunet.
220 uunet FTP server (Version 4.109 Wed Nov 19 21:52:18 CST 1986) ready.

Password: ********
230 User johndoe logged in
Remote system type is UNIX.
Using BIN mode to transfer files.
ftp> put porthack.exe
200 PORT command successful

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:

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. Around you is a forest. A small stream
flows out of the building and down a gully.


login and use the save command..
BASIC Interpreter

To enter the basic interpreter, type BASIC.

@ basic
Dartmouth DTSS TeleBASIC (c) 1964,1966,1969,1970,1971,1979

The basic interpreter subsystem has a number of historical programs
compiled from the SIMTEL archives as well as other sources. To see a full
list of available programs, type DIR within basic. You can load a program
with LOAD or begin execution with RUN.

Basic commands are:

> help
delete delete a user program
dir directory of basic programs
help print this list
list list the program in memory
load <file> load program from file
quit exit the basic interpreter
run run the program in memory
run <program> load and run the specified program file
save <file> save a user program

Example basic session:

@ basic
Dartmouth DTSS TeleBASIC (c) 1964,1966,1969,1970,1971,1979

6502 System Monitor

To enter the system monitor, type:

@ call -151
1441102 96 14 STX $14,X

Monitor commands are:

d dump memory
l disassemble cpu opcodes
r return to last jsr point
g execute address

The memory dump will show the octal address on the left column, the hex
values for the memory at that address, and an ASCII translation of the
memory values:

2364636 60 01 2C 26 6C D1 68 C7 45 40 1A F9 39 66 23 21 `.,&l.h.E@..9f

To disassemble CPU instructions instead, use the l command:

2366320 63 SUBD2
2366321 04 25 TSB $25
2366323 64 9C STZ $9C

2366332 31 09 AND ($09),Y
2366334 A3 MOVAB
2366335 44 PUSHAW

If an entry point in the system monitor is known, you can execute it with
the g command:


To return to the Telehack command shell from the system monitor,
use the r command.
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

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 )

Some additions have been made to the usenet archive available on
Telehack which have been provided from other sources.

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.
