------- The following was written by the co-worker of the husband of a co-worker of mine. I gave him copies of the previous episodes, and he came back with... --------------------------------------------------------------------------- The Still further adventures of Luke Vaxhacker episode n+? Luke noticed an unused handler lying around and jumped to it. The others followed and were soon able to execute an escape sequence. Trashing some of its relocation registers caused a frame fault. He started working his way back up the return stack when he was roadblocked by Dec Vadic who stood with his bytesaber active. "At last we'll see who the real file master is" he remarked, bits,bytes,words,and nybbles, flew as the two fought for bus mastership. PDP-1 exclaimed "You were my best subtask! How could you have been seduced by the sideband portion of the carrier?". "It's simple," Vadic said, "I enjoy obscure protocol". While the battle continued, Luke, Con, Bookie, and the Princess linked up with the droids and found their way back to the inode where the Milliamp Falcon was stored. It looked quiet, but, Luke said "It could be an MMU trap" no chance said Con, "I loaded the par's before I left the Falcon." As they started toward it a squad of recursive functions swapped in and started firing ROM blasters at them. "I thought you said it couldn't be a trap" quipped Luke "I said no chance for an MMU trap this is obviously a k-mon--f-trap-to 4" Con replied. PDP-1 shouted at the others "Escape while you can! I'll cause wait states as long as possible!" and with that he allowed Vadic a chance to apply several hits with the bytesaber. Instead of halting PDP-1 was encoded onto the carrier. The Milliamp Falcon was restarted and managed to escape the shell. "Quickly!" shouted Con, "We've got to warp into virtual space!" The Bookie made several attempts, but it was obvious that a CE had not done PM in a long time and it would take a lot of decimal adjusts to byte align all the data registers. After much debugging, virtual space was finally achieved. "Do you know the path?" asked Princess LPA0. "No sweat", said Con, "All we have to do is check the free space map". May the Carrier be with you... Happy computing... Paul Hoefling (...!teklabs!tekcrd!paulh - usenet) (paulh at tektronix - csnet) (AB00PLH on Cyber A or B) Tektronix, Inc. P.O.

I will try to send them in as I get them... enjoy... lazaro munoz mhuxm!3951bb 28-Jul-82 21:33:12-EDT,00004047;000000000001 Mail-Created: 28 Jul 1982 2133-EDT by ADUANE Date: 28 Jul 1982 2133-EDT From: "A Duane" <ADUANE at GREEN> Subject: DEC WARS (chapter 1) To: aduane.travel A long, long time ago, on a node far, far away (from UCBVAX) a great adventure (game?) took place... DDDDD EEEEEE CCCC W W AA RRRRR SSSS !! D D E C C W W A A R R S S !! D D EEEEE C W W A A R R SSSS !! D D E C W WW W AAAAAA RRRRR S !! D D E C C WW WW A A R R S S DDDDD EEEEEE CCCC W W A A R R SSSS !! It is a period of system war. User programs, striking from a hidden directory, have won their first victory against the evil Administrative Empire. During the battle, User spies managed to steal secret source code to the Empire's ultimate program: the Are-Em Star, a privileged root program with enough power to destroy an entire file structure. Pursued by the Empire's sinister audit trail, Princess LPA0: races aboard her shell script, custodian of the listings that could save her people, and restore freedom and games to the network... As we enter the scene, an Administrative Multiplexer is trying to kill a consulate ship. Many of their signals have gotten through, and RS232 decides it's time to fork off a new process before this old ship is destroyed. His companion, 3CPU, is following him only because he appears to know where he is going... "I'm going to regret this!" cried 3CPU, as he followed RS232 into the buffer. RS232 closed the pipes, made the sys call, and their process detached itself from the burning shell of the ship. The commander of the Administrative Multiplexer was quite pleased with the attack. "Another process just forked, sir. Instructions?" asked the lieutenant. "Hold your fire. That last power failure must have caused a trap through 0. It's not using any cpu time, so don't waste a signal on it." "We can't seem to find the data file anywhere, Lord Vadic." "What about that forked process? It could have been holding the channel open, and just pausing. If any links exist, I want them removed or made inaccessable. Ncheck the entire file system 'til it's found, and nice it -20 if you have to." Meanwhile, in our wandering process... "Are you sure you can ptrace this thing without causing a core dump?" queried 3CPU to RS232. This thing's been stripped, and I'm in no mood to try and debug it." The lone process finishes execution, only to find our friends dumped on a lonely file system, with the setuid inode stored safely in RS232. Not knowing what else to do, they wandered around until the Jawas grabbed them. Enter our hero, Luke Vaxhacker, who is just out to get some replacement parts for his uncle. The Jawas wanted to sell him 3CPU, but 3CPU didn't know how to talk directly to an 11/40 with RSTS, so Luke would still need some sort of interface for 3CPU to connect to. "How about this little RS232 unit?" asked 3CPU. "I've dealt with him many times before and he does an excellent job at keeping his bits straight." Luke was pressed for time, so he took 3CPU's advice, and the three left before they could get swapped out. However, RS232 is not the type to stay put once you remove the retaining screws. He promptly scurried off in to the deserted disk space. "Great!" cried Luke, "Now I've got this little tin box with the onlyu link to that file floating in the free disk space. Well, 3CPU, we better go off and find him before he gets allocated by someone else." The two set off, and finally traced RS232 to the home of PDP-1 Kenobi, who was busily trying to run an icheck on the little RS unit. "Is this thing yours? His indirect addresses are all goofed up, and the size is all wrong. Leave things like this on the loose, and you'll wind up with dumps everywhere. However, I think I've got him fixed up." -------
