Re: [SLUG] modem dialup
Thanks for all your help - I gave up and re-installed a new flavour, in the end - PCLinuxOS, which I am extremely pleased with thus far. And, if you don't mind a fast learning Linux/wi-fi/OOP/security enthusiast from Melb joining, I think SLUG sounds heaps better than MLUG. Hey - I have cousins in Roseville and Concorde, so if there's a job at the end of my Masters in Sydney - Would I relocate? Would I ever - Zounds! Thanks for all your help on my entry level problem. Fantastic! Oh - anyone think a thread discussing the realities of the Cyber project which is key to the Dr Who storyline currently airing on the ABCLinux has already beaten MS in the UN's global OLPC project, and they have zero local storage at all, complete Network terminals.

[SLUG] Thanks Re: Cron and shutdown command
Thanks Dean, Simon, Zhasper and Martin. Got crontab to shutdown my PC at a predetermined time thanks to your assistance. Martins suggestion of using shutdown -h 200608142000 is interesting. Will try that next time. I just wanted to automatically shutdown my Mythtv ( MythDora) PC after a late-night recording of a TV program was finished, just like a VCR does, and to be able to set my PC to do this anytime that I configure a recording. In other words, each auto shutdown is an individual once-only operation. Crontab worked fine. Unfortunately, although MythDora recorded fine, the channels were not setup correctly. ie Nine Digital actually recorded 10, though Nine HD works fine, and selecting Nine Digital to view a program also works fine. Some problem with the Program Guide I think. Will setup the Channels again. Thanks Your replies showed once again that in Linux there's always more than one way to skin a cat, so to speak.

Just like you I was also a computing student and you won't really learn anything if you don't exert any effort in working out these problems.

When turned on the autoclean feature will remove any packages which can no longer be downloaded from the cache. If turned off then packages that are locally installed are also excluded from cleaning - but note that APT provides no direct means to reinstall them. It looks like turning it off will leave you with a cache that slightly more accurately represents the packages that are installed on a machine after doing an autoclean. But if you're looking to mirror the installed package list on the box you're upgrading, you'd want to do something like: - On the first machine, run dpkg --get-selections packagelist to get the status of all installed (and removed) packages. - Transfer packagelist to the second machine and run dpkg --set-selections packagelist to set the desired status of all of those packages. - Run apt-get dselect-upgrade , which will then go about installing/removing things to change desired status to actual status.

Re: [SLUG] apt questions - apt-cacher and /var/cache/apt/archives
Top posting because I'm re-explaining the problem, and btw, I've searched debian.org and google and can't seem to find the answers to any of these questions: I've found a thing called apt-cacher which looks like a nice simple way to locally cache packages for upgrading other boxes. I've installed it on my main desktop box, which had already been updated to Dapper. I want to seed apt-cacher so that I can use it as a source.list for other upgrades. I think that means that I need to seed it with all the currently installed Dapper packages, but presumably NOT any old packages. so... I'm thinking I should do: #apt-get autoclean -o APT::Clean-Installed=off #cp /var/cache/apt/archives/* /var/cache/apt-cacher/import/ #/usr/share/apt-cacher/apt-cacher-import.pl then change my other boxes sources lists to point to apt-cacher on this box - voila! It sounds easy, but it also looks like a great way to screw up a perfectly good install, so I'm looking for some advice/confirmation :) many thanks... David PS: I notice that apt.conf is now apt.conf.d/ but I can't find any description of how the various files work, or if there is a precedence etc etc. Is there a howto or whatever?

Unless you've removed packages, the contents of /var/cache/apt/archives represent every single package ever installed on that system, regardless of whether a package was subsequently removed, or replaced by an updated version. apt-get has a couple of commands for managing the package cache. apt-get clean will clear out the cache completely. autoclean is a little more intelligent. Check the apt-get man page for details. Thanks for that. From the man page: autoclean snip APT::Clean-Installed will prevent installed packages from being erased if it is set to off. How do I set APT::Clean-Installed? Google hasn't helped :( Is this what I'm looking for? I'm not sure. What are you looking for? :-) /usr/share/apt-cacher/apt-cacher-import.pl That needs to be in apt's config file, /etc/apt/apt.conf . You'd want to add APT::Clean-Installed false; From the apt.conf manpage: Clean-Installed Defaults to on. When turned on the autoclean feature will remove any packages which can no longer be downloaded from the cache. If turned off then packages that are locally installed are also excluded from cleaning - but note that APT provides no direct means to reinstall them. It looks like turning it off will leave you with a cache that slightly more accurately represents the packages that are installed on a machine after doing an autoclean. But if you're looking to mirror the installed package list on the box you're upgrading, you'd want to do something like: - On the first machine, run dpkg --get-selections packagelist to get the status of all installed (and removed) packages. - Transfer packagelist to the second machine and run dpkg --set-selections packagelist to set the desired status of all of those packages. - Run apt-get dselect-upgrade , which will then go about installing/removing things to change desired status to actual status.

[SLUG] Is there a which mirror is best tool?
Many ISPs around Australia (all?) have peering arrangements with other ISPs (or, rather, groups of ISPs). Traffic between peers does not count towards my download limit. And I'm guessing they are faster, too, due to less busy links between peers. My ISP is peopleTelecom. Given a host name (or an IP address), can I tell if it is a peer with my home IP address? PT say who they peer with, see http://bc.whirlpool.net.au/isp.cfm/People-Telecom/129.html, PIPE, WAIX and AUSIX, but the connection to a particular host name (or IP address) is quite tenuous, as each of these peers have multiple member ISPs who each have multiple customers, many with their own domain names. It all boils down to this: when I look down a list of mirror sites, is it possible for me to tell which ones are peers, which ones are cheapest to access? -- Regards Peter Miller [EMAIL PROTECTED] /\/\*http://www.canb.auug.org.au/~millerp/ PGP public key ID: 1024D/D0EDB64D fingerprint = AD0A C5DF C426 4F03 5D53 2BDB 18D8 A4E2 D0ED B64D See http://www.keyserver.net or any PGP keyserver for public key. signature.asc Description: This is a digitally signed message part -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html

In the same context, the input is not specified, so the default is used which is std.input == 0. That's why $cat 1m1 means concatenate std.input into filename m1. I understand what both you and Jamie are saying. cat concatenates stdin(0) because a file wasn't specified, in the same way I normally use $ cat file to create text files. I was emphasising on what 1m1 actually meant, so there is still nothing wrong with what I said: 1 is actually stdout as mentioned in my previous message. You're redirecting to m1 what cat is outputting to the screen and not what your entering to the keyboard which is what actually happens _in between_ keyboard entry and writing to the file m1: 1. cat concatenates stdin(0) 2. cat echoes what it read from stdin to stdout(1) 3. bash reads from stdout(1) 4. bash redirects what it read from stdout to file m1 Carlo -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
