From jmjoseph at andrew.cmu.edu Sun Jul 4 12:36:33 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Sun, 04 Jul 2004 12:36:33 -0400 Subject: [auton-users] Bad Passwords & Backups Message-ID: <40E83211.2010206@andrew.cmu.edu> Hi. I'll get straight to it: Passwords: ----------------- I regularly attempt to crack the lab users passwords with a few automated tools. Aside from the obvious implications for the specific user, weak passwords pose a threat to the entire lab network. Such potential access exposes otherwise private, and inherently trusted resources to untrusted users, opening the entire lab to any number of exploits. I WILL BE SENDING SEPARATE EMAIL TO THOSE USERS WITH WEAK PASSWORDS. A few key points for all: * Use at least 8 characters. 6 is not enough, even if random. * Do not use your user name in your password. * Do not use a single name or word, such as a character from a fantasy novel or movie. Backups: ------------------ I've reworked my own scripts a bit and want to remind everyone of the lab backup policy: *When: Nightly at 2am. *What: -Home directories smaller than 15GB are backed up entirely. -All databases are backed up. -Those home directories which are larger must have a ~/backup.lst to indicate which files are backed up. *How long: The general policy is to store the backups as long as possible with the space I have. For now, it looks like I can guarantee the 2-3 most current weeks. -Jacob From jmjoseph at andrew.cmu.edu Mon Jul 5 16:14:21 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Mon, 05 Jul 2004 16:14:21 -0400 Subject: [auton-users] mailling lists web interface Message-ID: <40E9B69D.5020900@andrew.cmu.edu> As part of an upgrade of Mailman, the mailling lists manager, I've temporarily removed access to the web interface for such things as changing passwords and viewing the archives. It'll be back tomorrow. -Jacob From jmjoseph at andrew.cmu.edu Tue Jul 6 01:25:21 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Tue, 06 Jul 2004 01:25:21 -0400 Subject: [auton-users] Mailing lists Message-ID: <40EA37C1.7030406@andrew.cmu.edu> The mailing lists and archives have been migrated and are back up. -Jacob From jmjoseph at andrew.cmu.edu Mon Jul 12 14:47:02 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Mon, 12 Jul 2004 14:47:02 -0400 Subject: [auton-users] More Opterons! Message-ID: <40F2DCA6.4020608@andrew.cmu.edu> I'd like to announce the two new opterons are up and ready to go! I'll get them up on the status page later today. The naming convention has been continued as follows: lopX: 4GB loqX: 8GB lorX: 16GB The new machines are: loq3 : 8GB ram lor1 : 16GB ram -Jacob From jmjoseph at andrew.cmu.edu Mon Jul 12 15:19:59 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Mon, 12 Jul 2004 15:19:59 -0400 Subject: [auton-users] lor1 problems Message-ID: <40F2E45F.7010005@andrew.cmu.edu> Well, we're hardly off the line and are having a few problems with lor1. It's throwing a few ECC errors. I'll take it down a bit later for further testing and repair. -Jacob From jmjoseph at andrew.cmu.edu Mon Jul 12 15:28:58 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Mon, 12 Jul 2004 15:28:58 -0400 Subject: [auton-users] loq3 and lor1 down Message-ID: <40F2E67A.1060104@andrew.cmu.edu> loq3 and lor1 have been taken down. -Jacob From jmjoseph at andrew.cmu.edu Thu Jul 15 15:34:26 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Thu, 15 Jul 2004 15:34:26 -0400 Subject: [auton-users] lop3 down for testing Message-ID: <40F6DC42.4000800@andrew.cmu.edu> I'm briefly taking lop3 down to use some of its parts to test loq3 and lor1. I should be less than a half hour. -Jacob From jmjoseph at andrew.cmu.edu Thu Jul 15 16:39:41 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Thu, 15 Jul 2004 16:39:41 -0400 Subject: [auton-users] lop3, loq3 back Message-ID: <40F6EB8D.1000306@andrew.cmu.edu> I've brought lop3 and loq3 online. I'm being a bit more cautious with lor1. -Jacob From jmjoseph at andrew.cmu.edu Thu Jul 22 14:19:00 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Thu, 22 Jul 2004 14:19:00 -0400 Subject: [auton-users] loq2 down Message-ID: <41000514.3080804@andrew.cmu.edu> I've temporarily taken loq2 down for testing. -Jacob From jmjoseph at andrew.cmu.edu Fri Jul 23 01:26:04 2004 From: jmjoseph at andrew.cmu.edu (Jacob Joseph) Date: Fri, 23 Jul 2004 01:26:04 -0400 Subject: [auton-users] all Opterons up Message-ID: <4100A16C.6050003@andrew.cmu.edu> Hi. I've enabled access to all of the Opterons. loq3 and lor1 are still throwing sporadic *corrected* ECC errors when run under kernel 2.4. The errors are related to their higher density 2GB modules. The errors do not occur under kernel 2.6(which lacks AFS support) or during memory tests, and those that do occur are all correctable, so I am not convinced they are actually occurring at the hardware level. As such, I'm confident in opening the machines up for general usage. I'll of course keep a closer eye on them until I get to the bottom of this. Thanks for your patience and sorry about all of the emails... -Jacob From dpelleg+ at cs.cmu.edu Fri Jul 23 16:01:37 2004 From: dpelleg+ at cs.cmu.edu (Dan Pelleg) Date: Fri, 23 Jul 2004 16:01:37 -0400 Subject: [auton-users] reserve lop1 Message-ID: <16641.28321.270889.342900@lark.auton.cs.cmu.edu> I'm reserving lop1 for the weekend.
