For Sale: Alpha PWS 600AU
by Phillip G Deneault 19 Jan '06

19 Jan '06

600mhz Alpha with 384megs of ram. On board sound and LAN. This is a REAL AU model, with the qlogic SCSI card and the powerstorm video card(in case you wanted to run OpenVMS). I would recommend using a different video card or using the serial console for anything BSD or Linux. I believe it has a 9 gig SCSI disk in it, but I've suplemented it with a 50gig IDE drive on the IDE chain. I've also replaced the IDE CD-ROM with an 68-pin SCSI CD-ROM(yes, thats right, 68-pin). I also have all the original docs with it. I was running FreeBSD 5.3 on it until a week ago when I upgraded the machine. Nice little hobby system. $200 bucks or best offer. If anyone has any questions, or wishes to haggle, please reply to me(and not the list, they hate that). Thanks, Phil

Re: [Wlug] encrypted files
by Stephen C. Daukas 14 Jan '06

Chuck hit the nail on the head... The general question that is best to begin with is 'what do you want to protect and what is it worth?' The common metaphor used in security is 'how much does it cost to build the wall versus the value of what the wall protects.' In other words, long keys and the time to encrypt/decrypt, etc., etc., is probably not what you want for your everyday files. It this really is required for everyday files, you are into a model similar to what government agencies do (google "Orange Book" - the nickname for the US standards for computing security - at least when I was into this stuff - but the concepts remain the same). If there are a few things that are really vital, then compartmentalize them and apply lots of security to them (i.e., don't keep them on a hard drive that is on a network - physical security - or encrypt them on removable media - soft and physical security). Depending on what the value is, you can start getting into all kinds of systems that are a real pain to use (and that is another reason why they are more secure). There are lots of other ways to make security easier and still useful. Another approach is "something you have and something you know" - that is how ATMs work. You could put your rings on a thumb drive (like the ATM card) that you unlock with a simple key (pin) that gets you to the next step - using the ring for the encryption you were after to begin with. Retinal and finger print scanners (biometrics in general) are essentially this model. If you loose either piece of the system, the other is no longer useful. Another approach is a so-called "smart card" - these are used in Europe for money, but variations are also used to turn the "key" into something approaching a "one time pad"... The card calculates a decay sequence of some sort (a non-linear countdown with a seed you select) that is also calculated on the system you want access to. You type in the calculated value as *part* of the password (valid for say 5 seconds to allow for boundary conditions) and if the system has the same pattern - your are in. I personally think encrypting entire file systems is far less secure than you might think - it is better to protect several areas with several different methods so that compromise of the entire system with one successful attempt doesn't happen. To be honest with you, my bias is towards physical security - I use a thumb drive and then only parts of it are encrypted.

encrypted files
by Bill Mills-Curran 14 Jan '06

I have a question about using gpg to encrypt private files on my system. Which encryption is the preferred for file storage? Symmetric? (gpg -c) This seems the most secure and flexible, but I'm getting tired of typing the key so often. Public/private? This seems enticing, because encryption is done without needing to type a password. However, the keyring is on the same system as the encrypted file, and thus is vulnerable. Thanks, Bill

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 HI Everybody, We'll be having a WLUG meeting this coming Thursday evening, at 7:00 PM, on January 12, 2006 in the Access Grid room on the WPI campus in Worcester, MA USA. At this meeting, there is currently no single scheduled topic, so this means that ALL topics are freely available for discussion (thanks, Walt). Bring along your questions and maybe somebody in the room will have answers. Bring up any Linux related topic and we can discuss it as a group. Here are some topics we might discuss: Nokia 770 - http://www.nokia.com/770 Linux World Conference and Expo coming to Boston in April 2006 Richard Stallman will speak at WPI on January 13th Xen in the Linux kernel (see also Xenoppix) Next month (Feb 2006), I'll probably put together a presentation discussing my experience using a Routerboard 532 and making a firewall out of it using GPL software which I pieced together. Stay tuned. After the meeting, we'll go out for pizza and soda at our favorite pizza place (Tech Piza) on Highland Street. We always have lively and interesting discussions there. Come one, come all, and bring your friends, too!

I found a contact address for events @ wpi and recieved this response, good news. >From Michael C Voorhis <mvoorhis(a)cs.wpi.edu>: I'm not aware of any restrictions on the audience. The event description doesn't imply any restrictions (I just looked) and I would believe RMS to be opposed to any restrictions in any case.
