[SLUG] Tar backup of links
Hi all, how does tar handle links? I have several nested layers of folders and some of them are linked back to other folders. If I use tar to make a backup of the root folder and subfolders, does tar backup the link files or does it backup the REAL files? Such that if I do a restore, I want the link files there... not replaced with copies of the real files. Still googling for answers... is there a command switch? Hope this is clear.

[SLUG] Another good reason to stick with NON-DRM'd stuff
Saw this e-mail from Bigpond today (they're not my
ISP).
**
*Dear BigPond^® Music Member,*
BigPond Music won't be supporting the Windows
Media Audio ('WMA') file format after 1 April
2010. That means you won't be able to download new
DRM (Digital
Rights Management) 'unlock' keys for the WMA files
you've bought from us already
- so you should back up your music now.
Any MP3 files you've bought from us won't be
affected. Read further if you want to know more
about WMA files.
*Here's why you should back up your music.*
As long as you keep using the same computer and
operating system, you shouldn't have any trouble
playing your WMA music files. But if you try to
move them onto a new computer or operating system,
they won't work if you don't transfer their DRM
keys as well.
Besides, backing up your collection is a good idea
- for your MP3 files too.
*So here's what to do.*
You can back up your music collection now, by either:
1. Burning it to audio CD (Click here
to find out how.)
2. Backing up your WMA files and licences
separately (See how to do it here
.)
*Additional information on WMA's & DRM.*
All our music was in the secure WMA file format
when BigPond Music started. Whenever you
downloaded a WMA file you downloaded it's
encrypted Digital Rights
Management ('DRM') code at the same time.
DRM is a kind of lock and key system. The key
unlocks the music so that it'll only play on your
software. The downside of this security is that
WMA downloads
don't work on popular systems like Apple's iPod
and iTunes software. It's also hard to move WMA
files without downloading a new licence key.
We started selling MP3 files without any DRM or
licence key restrictions in August 2008. MP3's are
a much more universal format that works on most
digital music players and software. We stopped
selling WMA files in March 2009, and only offer
MP3 music now.

Feel sorry for those who were suckered in.

Re: [SLUG] A little script help
I find password generated like that to be too hard to remember. This is one that I used to use. Repeat until you have a set of three words you can remember. It doesn't match your criteria, but it does produce something that's reasonably unguessable, and relatively easy to remember. --- #!/bin/sh DICT=/usr/share/dict/words # Pick three words w1=`shuf -n 1 $DICT` w2=`shuf -n 1 $DICT` w3=`shuf -n 1 $DICT` echo $w1 $w2 $w3 --- -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

I advise 'apg', which is packaged for most distributions. While it has some theoretical weaknesses[1], it is sufficiently strong that it should beat any non-targeted attack. The advantage of it, though, is that it generates passwords that follow the same basic rules of structure that English words do, so they are remarkably easy to memorise and use in practice.[2] [...] > 2. Split the loop to three - one which picks a first letter from the >uppercase-only string, one which picks 5 characters from LORD and one >which picks 2 characters from the digits-only string. Ideally, you would want to rewrite this as a function which takes a candidate set of characters, picks a random character from it, then returns that. Then you could make it easy to template your passwords to whatever length and complexity you need. Regards, Daniel Footnotes: [1] It uses a generation model that doesn't produce perfectly random results, by selecting from the pool of valid results. This introduces imbalances in the generated parts-of-speech in the passwords, allowing you to substantially reduce the search space over a fully random password generator. If you are concerned, and care more about probably-theoretical security then there is a Perl implementation of the same idea which uses a fully-random password generator, and then tests the generated password for compliance to the parts-of-speech model. That removes the bias, and is as theoretically secure as a fully random password when the same number of bits of entropy are included. Obviously, the use of filtering means less bits-per-character. :) [2] Every time I tell someone this, they don't believe me, because it doesn't look easy to memorise. In practice, they never fail to be amazed how well they did committing it to memory after the fact. -- ✣ Daniel Pittman✉ dan...@rimspace.net☎ +61 401 155 707 ♽ made with 100 percent post-consumer electrons -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

Most of my important passwords are used well enough that by now I remember them (and they are strong enough that I don't have to change them very often). If you insist on implementing it yourself as a scripting exercise then: 1. Add an uppercase-only string and a digits-only string on top of the LORD one you already have 2. Split the loop to three - one which picks a first letter from the uppercase-only string, one which picks 5 characters from LORD and one which picks 2 characters from the digits-only string. The way you have it now there is no way to guarantee that the first character will be an upper-case letter or that the last two will be digits. --Amos -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
[SLUG] A little script help
Hey everybody. I am using this script at the moment. It a little password generator script I was wondering if anyone could help me out. I would like the First letter to be a Capital and the last two to be any digits? The one that I have puts capitals all over the place and sometimes it does not have any number's at all. I plan to use this for work for the (DRN) I have run out of things to put as my password and I am not aloud to have the same password twice Thanks in advance Josh. passwoard_gen Description: application/shellscript -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
