RE: [SLUG] Question about PGP
Steven, I assume you are referring to the PGP signatures appearing at the bottom of some postings. (They are not keys as you mentioned). These signatures allows you as the reader to verify two things 1. That the sender in fact is who he/she says he/she is. 2. That the message contents is as was sent (it is unaltered from when they signed it) For the signature to be useful, you need to have the sender's public PGP key. You would normally obtain this from them personally, or from their web site, or some other secure means (often via another signed document from someone you already trust - this is known as a certificate). You then run the received message through the PGP application, together with the purported sender's public key, which will then confirm that the private key of the sender was used to sign the message (the public is generated from the private key by the sender). You then can be sure the message is as it says. Why would you need to use PGP to sign a message? The answer would vary, but I imagine most signers do it simply to assure themselves that what they have said is what is read. Whether you need to do this depends on how much you trust the mail and transport systems used to convey the message between sender and receiver. Most of us just have a reasonable level of trust that things won't go wrong - either malevolent or otherwise. I imagine it will take a few nice public cases of email tampering and we might all start signing.

Steven Chang-Lin Yu wrote: Hi, I would like to know the benefit of using PGP? I have notice some of the SLUG member uses PGP key on their message, is there any advantage??? Here is a real situation that cropped up this week for me where PGP (or GPG - the freer version) would have been useful if everyone was using it. I have a database where we are changing servers and about a dozen users who have 'advanced access' haven't had a password change in two years so its about time I dropped their password and created a new one for them. The problem is how to get their password to them securely when they are in various States. Last time I just emailed them the passwords and got told off - and rightly so. This time we will use the telephone or stamped self-addressed envelopes and trust Aust Post :-) Here is what I could do if we all had public/private keys. I generate a password for a user and encrypt it using their public_key from their web page or from an email that they send me. I attach the encrypted password to an email to the user and sign the email that I send out using my private key. The user recieves the email and checks the signature on it using my public_key. Now they KNOW it is from me and not from an interloper. They extract the encrypted password and unencrypt it using their private key. Anyone that did intercept that email will not be able to decrypt that password. But alas these dozen people dont know about public/private key stuff nor PGP so we will use snail mail. That shows one of the advantages of PGP. Interestingly I only downloaded GnuPG yesterday and have just generated my keypair.

[SLUG] Require advice on Biblio software
Hello :) I've spent a few hours searching sourceforge.com and Google for open source library systems for Linux and managed to testdrive some biblio projects via their online PHP demos. I was looking for some of the same standard and functionality found in most council/state library catalog systems. It seems that most ILS (Integrated Library Systems) are web-based nowadays - and found OpenBiblio, Emilda, and Koha. Emilda seems premature and requires more testing. OpenBiblio seems nice, with membership ID card support, MARC support (a standard created for cataloging books or other documents used in a library eg. ISBN, Title/Author/Subject) etc, membership database, circulation, fines/penalty, due dates etc. Koha seems more extensive than OpenBiblio with aquisition support ((re)order, receive, budgeting), member search borrow history information which is accessible by members via a member access plugin. I need an application to inventory, track member loans and borrowings mainly for paper material types (because most of our property is paper based) eg. books, magazines, cds, and anything you could probably detail using biblio cataloging standards like MARC, Z39.50 etc for a chess club. Our club also stocks non-biblio material like computer equipment, chess sets and pieces, and demonstration kits that require inventory - mainly to track missing stuff and keep a list of what we have, where it is, who currently is/isn't responsible/ownership etc. At this stage, due to the slightly different nature and purpose of the type of things (1. books, 2. equipment), and method, and possibly insufficent awareness of the full capabilities of existing software mentioned above (et al), I was conceiving tracking books with a biblio system, and using an Excel spreadsheet to track equipment. I'm thinking about proposing OpenBiblio as our solution. Does anybody suggest a good library system ? Maybe an all-in-one biblio stock inventory system ? -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

[SLUG] USB HID IR device - how generic can I go?
Hey gang, So I got this USB IR port and remote bundled with my DVB card. I'd kinda like a generic IrDA port to use with my phone and iPaq, so I'm wondering if I can use this one. What worries me is that it comes up as a USB HID mouse and keyboard device, which is kinda cool for use with the remote, but I don't know if that'll let me use it with the IrDA stack. I get the vague impression from some Googling that the HID stuff is just a layer on top of the standard IrDA stuff that the hardware already does, and Linux might be able to talk to both at the same time. *attempts to wave hands intelligently* I've popped lsusb -v output for it at the bottom of this mail.

[SLUG] Desktops
Hey all, I've been getting a lot of requests from people for whom I've setup Linux desktops who are becoming increasingly frustrated with the fact that their Linux box doesn't behave like windows. There's a bunch of ways this manifests, but most commonly I field complaints that OpenOffice is completely unusable on the basis that menu items are arranged differently. Another complaint was on the basis that OOCalc required an '=' prefix on formulae -- apparently Microsoft Excel will recognise formulae if they start with a '+'. I did review the various office apps available on Linux some time ago and ultimately concluded that OpenOffice was the best migration path from Windows - Linux -- if there's something better out there though, I'd like to hear about it. Anyway, my question: what steps can I take to make a Linux box behave more like Microsoft products? I'm interested in all kinds of approaches here -- switching distributions (though I'd need to see some pretty compelling reasons to do so), bizarro patches, whatever. I am aware that MS-Office will run under WINE -- I'm giving that due consideration. Thanks guys, James. -- James Gregory [EMAIL PROTECTED] -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

On Sat, May 08, 2004, Angus Lees wrote: .. so with all that manual spam/ham classification/archiving, is there actually any point running an automatic spam filter anymore? Well, depends on what you mean by all that. About three times a week, a mail ends up in the wrong folder. (That's an error rate of about 0.15%.) I move those three mails to the right folder so that they get learned correctly. Once a week a cronjob fires and learns whatever happens to be in my mail folders at the time. I'm happy with manually moving three mails a week. I spend more time 'training' procmail than I do training my Bayesian filter. (Please do not wave the magical procmail rule at me, because the Linguist List don't put the right headers in their mails and therefore it is not the solution to the problem I'm thinking of.) The time investment is considerably less than all that manual spam deleting, for example. From what I can see any spam filter that needs training is missing the point - but I've never actually run any of the Bayesian filters so its purely ignorant prejudice ;) Well, it depends on what the point is. If the point is it is easy to tell spam from non spam with rules that are already in existence then contribute your rules to the SpamAssassin project because many people are finding that their rules degrade in effectiveness over time. SA, untrained, would miss about 15% of the spam I currently receive. If the point is it should be possible to tell spam from non spam with rules with an acceptable error rate that will not degrade for a long period of time you're probably right, but my suspicion is that coming up with those rules is like a lot of natural language problems: hard. If the point is spam just doesn't annoy me that much, and I'd rather just delete the stuff than spend more than 1 minute setting up a filter then we're different. -Mary -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
