Minor notes, none worth their own post.
Traffic management: I get a call from K around 5:30. She’s stuck behind an accident and the cops on the scene, a) don’t tell people to take a detour until they’ve been there for a half hour; and b) once the ambulance has left the scene, don’t direct traffic around the one remaining open lane. So, after waiting a half hour, K has to take a 20+ minute detour home. Memory: Once she gets in, K and I are fixing leftovers for dinner. C: “Hey, where are the mashed potatoes?” K: “Where did you put them?” “In the fridge, but I can’t find them.” “Maybe they’re in the freezer.” “Nope, not there either.” Ten minutes of looking for the potatoes. Did we throw them out on Sunday? Nope, not in the trash. Did C put them in the pantry? Nope. Can’t find ’em, can’t find ’em. Finally, K says, “wait, we fixed rice on Sunday.” There weren’t any potatoes. I would attribute it to getting old, but I’ve always been this way. FUD (fear, uncertainty and doubt): we’re testing some things at the office – will our authentication system (active directory) honor password failure lockouts when using LDAP authentication? I ask our windows consultant to either a) answer the question, or b) enable an account lockout policy so we can test. He responds back that he can do that, but with the warning that “many Linux services aren’t well-designed for this, and repeatedly try a cached or user-provided password, so that users or service accounts may be mysteriously locked out after one attempt or at some future time when passwords change.” Which is complete and utter B.S. Signs that it’s BS? He references Linux services as opposed to open source, i.e. attempted linux dig. And I used to “own” identity management services, including authentication at a large university and if this was the case, things would have blown up within 10 minutes. I thanked him for the advice and noted that I’ve never seen this, but that it’s why we test. OS Performance: we’re looking into some new ideas at the office. Things that could be useful as a preprocessor for a host based intrusion detection system. As part of my testing, I told my laptop to audit all syscalls made to the kernel, by all processes on the system. CPU load spiked, system performance went through the floor, the windowing system became almost completely non-responsive. In the two minutes it took to get access to a terminal, I logged 150 MB of audit logs. On the plus side, all of the information we need can be collected. Now I just need to figure out how to keep a usable system. Self aggrandizement: talking to my technical manager, we need to write up two journal papers based on our recent work. Cool! I hope everyone had a good Veteran’s Day and remembered to thank the veterans in their lives.
