*************************************** Hacking ARPANET -- Part III by The Source *************************************** ARPANET can't be faulted for the amount of information it is willing to disclose to anyone who knows the number of a dial-up and knows enough to type in "@N" and then follow directions. But the EXEC is, after all, limited to managing inter-computer phone calls. Even more interesting material is available once you get onto what is known as one of the network's "server" computers. OPENING THE DOOR ---------------- Once you have reached the Exec on a TIP, getting the door to a server machine to open to you is no problem. At the "@" prompt type "O" for open followed by a space and then by two numbers separated by a comma. The numbers represent the address of a computer system. The first number may be from 0 to 3, and the second number may range from 0 to 15: @O 0,11 TCP Trying...SU-AI WAITS 9.17/H Assembled 06/17/84 .Open The ".Open" shows that you're in. There is a great deal you can do at this level, and you don't even have a password yet -- as far as the system knows, you're still "anonymous guest"! Most server systems operate under the UNIX operating system, so any good manual on UNIX should tell you more than you need to know. But now that we've reached Stanford University's Artificial Intelligence Lab (having been switched there by SRI, formerly Stanford Research Institute), let's take a look at what's available. First, list the HELP files: .HELP Job 3 SU-AI WAITS 9.17/H Assembled 06/17/84 Type HELP followed by any of the following, then carriage return: ACCESS COMPIL EDITOR HOSTS MICROS PPK SORT UNDELE ACCOUN COPY EDKEY HOWBIG MIDAS PPSAV SOS UNPROT ACRONY CPRINT EFTP IIIPOX MLISP PRESS SOUP VERIFY ADA CRDIR EKL ILISP MLISP2 PRINT SPASM WEAVE ADAEDT CRE EMACLS IMPRIN MONCOM PRLISP SPINDL WEB AL CREF ESC INTERN MOORE PROLOG SPOOL WHEN ALIAS CRYPT ESCAPE JARGON MUSIC PROTEC SRCCHK WHERE ARKTEX CSD ET KILL NCOMPL PROVE SRCCOM WHO ARM D ETEACH KJOB NET PRUNE STICKY WHOLIN ARPA DART ETV KRL NETDOC PTYJOB SUTIP WHOPHN ARPANE DDFONT EVENT L NETWRK PUMPKI SYMBOL WL ASSIGN DDKEY EXT LATER NEWIO PUPTIM SYSTEM XGP ATSIGN DDQ FAIL LATEX NEWS RCV TALK XGPSYG ATTACH DED FASBOL LAWS NOEKEY REMIND TANGLE XGPSYN BAIL DFTP FCOPY LEDIT NOTEBK RENAME TECO XGPTYP BATCH DIAL FELT LIFE NSL RESOLV TELNET XIP BBOARD DIALNE FILES LIFXGP OPTION RESTOR TEMPER XPART BIBOP DIR FIND LINGO P RETRY TERMINK10 PAM SAIL TEX78 YUMYUM BMP DISPLA FONT LISP PASCAL SAVE TEX82 Z80 BOISE DM FORWAR LIST PASSWO SCHEME TFM ZERO BOOK DMKEY FRAID LOADAV PC SCIP TIP 370 BOYER DO FTP LOGIN PCP SCRIBE TTY 6500 CANCEL DOC GEOMED LOGOUT PHONE SD TTYCMD 6800 CANON DOVER GRIPE MACLIS PHONES SEND TTYESC 8080 CC DRAW GRUMP MACLSP PIX SERVIC TTYSET CHARGE DRD GUEST MAIL PK SIMPLE TVFONT CHRMAC DSKSIZ H19KEY MAP PLAN SLAC TYPE CKMAIL DTN HELP MAXTEX POLL SLR1 TYPREL COLIST E HELPER METAFO PONY SNAIL UDPUFD COMBIN ECL HOST MF POX SNOBOL UFD Type "HELP HELPER" for one-line descriptions of most of the HELP messages.

There are some commands that can be given without an account, as listed below. If you need to know more about any of these, type "HELP ". For information on special control characters and commands, type "HELP TTY". WHO, FINGER, WHERE, WHEN provide information about people and jobs currently running. MAIL, SEND, GRIPE permit you to send messages and converse with people on the system. (You can use SEND to ask someone who is logged in to form a two-way link with you.) DIR lists the files in specified d
