I think it was Greg Veal (the author of the CL book) who came up with the msg queue. He also did something similar with debugging a "remote" job. "Remote" meaning "another" in this case. -Bob Cozzi www.RPGxTools.com If everything is under control, you are going too slow. - Mario Andretti -----Original Message----- From: mi400-bounces-Zwy7GipZuJhWk0Htik3J/[email protected] [mailto:mi400-bounces-Zwy7GipZuJhWk0Htik3J/[email protected]] On Behalf Of Rich Hart Sent: Wednesday, July 20, 2005 10:40 PM To: MI Programming on the AS400 / iSeries Subject: Re: [MI400] Buffer overflow and code execution on iSeries Well, to continue off topic: There is yet a n o t h e r trick to make the SysReq line do interesting things. I thought it was Bob Cozzi who came up with it. It involves creating a temporary message queue object in QTemp and then send a message to that queue via the SysReq line with option 5 and using the temporary queue name. The message you send to the queue is then interpreted, via a break program, as a command. You can basically make it do anything you want, according to the logic of the message queue break program. I am surprised that Bob wrote a hook into the SEPT to accomplish similar tricks. Of course, I never heard of the SEPT until I read Leif's book. Anyway, Steven, if you want details on the message queue trick, feel free to contact me off list. The other tricks I had never heard of. Anyway, these things are still useful, although of course not essential. _______________________________________________ This is the MI Programming on the AS400 / iSeries (MI400) mailing list To post a message email: MI400-Zwy7GipZuJhWk0Htik3J/[email protected] To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/mi400 or email: MI400-request-Zwy7GipZuJhWk0Htik3J/[email protected] Before posting, please take a moment to review the archives at http://archive.midrange.com/mi400. _______________________________________________ This is the MI Programming on the AS400 / iSeries (MI400) mailing list To post a message email: MI400-Zwy7GipZuJhWk0Htik3J/[email protected] To subscribe, unsubscribe, or change list options, visit: http://lists.midrange.com/mailman/listinfo/mi400 or email: MI400-request-Zwy7GipZuJhWk0Htik3J/[email protected] Before posting, please take a moment to review the archives at http://archive.midrange.com/mi400.
