It was waaaay more than just reported to the local sysadmin, and almost got UCB kicked off the ARPANET.

>Actually, Dennis Perry is the head of DARPA/IPTO, not a pencil pusher in the IG's office. IPTO is the part of DARPA that deals with all CS issues (including funding for ARPANET, BSD, MACH, SDINET, etc...). Calling him part of the IG's office on the TCP/IP list probably didn't win you any favors. Coincidentally I was at a meeting at the Pentagon last Thursday that Dennis was at, along with Mike Corrigan (the man at DoD/OSD responsible for all of DDN), and a couple other such types discussing Internet management issues, when your little incident came up. Dennis was absolutely livid, and I recall him saying something about shutting off UCB's PSN ports if this happened again. There were also reports about the DCA management types really putting on the heat about turning on Mailbridge filtering now and not after the buttergates are deployed. I don't know if Mike St. Johns and company can hold them off much longer. Sigh... Mike Corrigan mentioned that this was the sort of thing that gets networks shut off. You really pissed off the wrong people with this move!

>Dennis also called up some VP at SUN and demanded this hole be patched in the next release. People generally pay attention to such people.

Jordan's infamous rwall incident is the kind of thing that might have triggered the rumored "explosive bolts" the Defense Communication Agency was once talking about installing, that would violently separate the MILNET and ARPANET in case of national emergency.

>DCA must have the ability to partition the ARPANET and MILNET in case of an "emergency", and having non-DCA controlled paths between the nets prevents that. There was talk some time ago about putting explosive bolts in the mailbridges that would be triggered by destruct packets... That idea didn't get far though...

Maybe that was too hard when people used to use hardcopy terminals (actual ttys), although even there it possibly could have done better than it actually does.

But certainly by the time people had softcopy terminals with cursor positioning (like the DEC VT series and its emulators), a better experience could have been possible. For example, what if the functionality of curses was actually in the tty driver, so if another process wrote to the terminal it would appear as a new window, which could then be dismissed without altering the output of the underlying program? Or, to avoid putting too much in kernel space, the tty subsystem could live in a user-space daemon (possibly one process per terminal), and then applications would talk to it over IPC

My admins were sadly mostly of the grumpy type, who did not like change, or initiative to solve peoples problem.
