Hi, If you were at the meeting, I was wearing a Debian t-shirt (with a red swirl logo on it) --- there's a photo at the top of this article, where I'm wearing similar stuff (except for the penguin ;-) http://www.linuxuser.co.uk/articles/issue6/lu6-Editorial-A_patently_bad_ide… I'm a Debian GNU/Linux developer, and run the UK Debian mirror, and am responsible for producing the Debian official CD images: http://www.uk.debian.org/ http://cdimage.debian.org/ I have only a peripheral interest in educational matters, in that I've been frustrated in the past in my efforts to provide free computers (which were otherwise destined for a skip), but I can certainly contribute on a technical side, and having been involved in Debian (which is completely voluntary, like OSIE is expected to be) since 1996 I may be able to make some suggestions about how to ``organise'' such a thing. For those of you who've not come across Debian before, we're a world-wide voluntary organisation (read, chaotic jumble of mailing lists) that puts together a Linux distribution (and soon a HURD distribution) and gives it away. Debian doesn't pay people to do this, and doesn't sell what it produces, and in most legal senses doesn't really exist (i.e. the machines in the mirror network mostly belong to people like me, rather than to Debian, and the bandwidth is donated rather than paid for). This probably gives a pretty good feel for what Debian is all about: http://www.uk.debian.org/social_contract which you will notice leads into the The Debian Free Software Guidelines (DFSG), which is where the Open Source Definition came from. My internet machine, that hosts the Debian UK mirror, may be of use to OSIE, since it has about 30GB of spare disk, and a 20Mbit/s connection at a well connected ISP. This machine could act as either a primary host or mirror site for the web site, and could do DNS secondarying etc. as well. Something I'd be interested in working on (although perhaps a SuSE list is not the right place to spend too much time discussing this ;-) would be producing Debian CD images, tuned to the needs of educational users. Debian has accumulated some funds in the UK, and have been looking for a worthwhile cause to spend them on (we never really need to pay for anything that actually makes Debian work, so don't have much use for money), so we could probably afford to have a few thousand CDs pressed, and send them out to schools that are interested.

iptables equiv. of ipchains -M -L
by Alex Brett 02 Apr '03

02 Apr '03

I used to use ipchains and i could type ipchains -M -L and get a list of outgoing connections through the NAT. Does anybody know if there is an equivalent command with iptables as I'm now using iptables and I'd still like to be able to display this info. Thanks, Alex Brett alex.brett(a)brettcomputers.co.uk

FW: [Ltsp-discuss] NX Project Announcement
by Chris Puttick 29 Mar '03

29 Mar '03

Now that's a shiny solution for a mixed environment :-) -----Original Message----- From: Gian Filippo Pinzari To: ltsp-developer(a)lists.sourceforge.net Cc: ltsp-discuss(a)lists.sourceforge.net Sent: 3/28/03 11:58 PM Subject: [Ltsp-discuss] NX Project Announcement Hi all, this message was sent to LTSP, GNOME and KDE developers' mailing lists. We invite everybody in these lists to check our work at NoMachine: http://www.nomachine.com NX is a commercial product and some parts are closed source, nevertheless all the core technology on which NX is based is and will remain OpenSource. This includes very, very good compression of X protocol that is the result of 3 years of hard development (I know it was hard, as I'm one of those who did it ;-). Beside software developed by NoMachine to handle X sessions, we integrated in the same infrastructure seamless access to RDP and RFB sessions through integration with RDesktop and and VNC projects. We would be glad to see close cooperation between LTSP, KDE, GNOME and NoMachine. We look forward to share not only our experiences, but even code, common architecture and desktop integration. Some early documents, among them an introduction to NX design goals, can be found here: http://www.nomachine.com/documentation.php Sources of core components are available at: http://www.nomachine.com/dev_sources.php There was a small thread in XFree86 forum these days were some technical issues about X as a remote computing platform and NX in particular were discussed. You can find it at: http://www.xfree86.org/pipermail/forum/2003-March/000629.html We believe NX is opening Linux to an unexploited market and can give to X new life in the form of what it was originally intended to be: a pervasive network computing platform. NoMachine provides a TestDrive server where you can freely connect and run as many KDE and GNOME sessions as you like. We think we have done a good job. Customers and many Linux developers that had a chance to try it were really impres- sed by the performances, but we want to hear from the real experts. Download the client from here: http://www.nomachine.com/download.php then get a user id and password from: http://www.nomachine.com/testdrive.php At the moment the test account never expires, so you can use it to compare performances in different network conditions. Even if you don't care about X compression, consider that NX includes everything is needed to make a MS Windows computer a X terminal, so you can do with it something useful :-). A last word about NX commercial software. As we said, all the core components (and especially the X related components) are OSS and released ad GPL. This means that everything the NX client and server do, can be done by hand by a normal user having an account on the remote server. We aim at the lazy users :-). NoMachine intends to provide the higher level software and the administrative tools that make possible to run thousands of users' sessions. We aim at the same customers of Citrix MetaFrame and SCO Tarantella. In the future, we envision a world where any application is available to any device, from anywhere in the world. To make this possible we needed efficient transport and compression of X-Window. Now it is there and everybody can use it. It's our interest to make our technology widespread. We would be glad to see an OpenSource version of NX client and NX server software and would be happy to see our OSS code in LTSP, GNOME and KDE projects. We'll provide all the help to make this possible. At the same time we think that a 100% OSS business model is not affordable for our company. We would like to contribute to build a free battleground where OSS and commercial software can cooperate (but even fairly compete) to make OSS technology win against proprietary solutions. /Gian Filippo Pinzari. -- Gian Filippo Pinzari Amministratore Delegato Medialogic S.p.A. ------------------------------------------------------- This SF.net email is sponsored by: The Definitive IT and Networking Event.

Can you install the extra HDD without the CDRW? -----Original Message----- From: Paul Taylor To: Suse-Linux-Uk-Schools Sent: 3/28/03 8:28 AM Subject: [suse-linux-uk-schools] HDD troubles Hi all: I have recently purchased a HDD and CDRW for my machine to improve the usability somewhat. However, on installing the devices, in any combination of jumpers and configurations, I seem to be getting interupt errors. The OS boots as far as "Scanning for new hardware" and hangs. When I do ctrl+alt+F10 I see the following messages: bad special flag 0x03 lost interupt no flushcache support This is repeated endlessly and it never boots. The device is dual boot with RedHat and that gets past this and shows the devices in the hardware list but they don't work. Also, the boot up shows that there is a floppy but I can't get that to work as it also has disk i/o error messages. Is it pilot error or a bad motherboard? Any help much appreciated.

OSS Conference - any chance of some sort of online relay?
by M.Blackmore 27 Mar '03

27 Mar '03

Just wondering (as I can't get there due to childcare issues) if there is any chance of any sort of online relay of the proceedings, papers which have been pre-submitted etc. One might have time to log on for a while and have a mooch about (like when baby has its nap).

Absolutely last call for OSS conference.
by James Spedding 27 Mar '03

27 Mar '03

The OSS in Education conference is taking place next Friday in Essex. www.mpowernet.anglia.ac.uk/conference/index.htm There has been a mad rush at the last minute but there are a few places left to join the other 85 or so delegates and speakers that will be there. The last possible date for delegates to register is tomorrow. Please call and let me know if you are interested. We are going to put a CD together with all the speakers notes, presentations and transcripts etc. a few weeks after the conference and I was looking for case studies of schools using OSS to include as well. If anyone knows of any I'd be appreciative of a link so we can put together as comprehensive a list as possible. Thanks, James

A year or so ago I wanted to dedicate a HDD to running Squid. These are the notes I kept from that exercise. I think I was using Redhat 6 at the time. The disk was already in the machine. Logged on as root. (Lines starting with # are commands to run) # fdisk /dev/hdb You get a colon prompt. Type p to print out current partition table. I noted down start [1], end [525[, blocks [4144770], ID [83], system [linux] from this info - numbers in [ ] are what I noted down. Type n at this colon to start the dialogue to create a new partition. The information you noted will allow you to make decisions on partitioning the drive. # mkdir /usr/local/squid Edit /etc/fstab to give /dev/hdb2 (this is the partition you created on hdb) a directory where it mounts - in my case /usr/local/squid. Create the filesystem for /dev/hdb2 with # mke2fs -c /dev/hdb2 4144770 This 4144770 number comes from blocks from the partition table info. My notes do say that maybe I should have done this straight after creating the partition with fdisk.) Then to make the changes to /etc/fstab take effect do: # /bin/mount -a I'd appreciate it if other people could critique and add to this.

As a matter of interest, we and many schools in Manchester are now looking at 16-19k for IT support engineers and £20+ for more senior people. I won't even mention what they now have to pay me ;-). Schools and education generally are learning the difference between quality IT and mediocre IT is not the supplier or the manufacturer, but the people who make it all work. -----Original Message----- From: Paul Munro To: suse-linux-uk-schools(a)suse.com Sent: 3/11/03 2:57 PM Subject: [suse-linux-uk-schools] Re: Test for prospective employees? OT Hi. Thanks to those who have answered so far. I think I will go with the idea that perhaps a practical exercise of some kind combined with the school's own "tests" (apparently psychometric?) will go a long way. I agree with the sentiments about pay; it's unfortunate that pay levels aren't high enough to sustain a good sert of technicians (especially the ones with family- I found it particularly hard on this wage level). You tend to get the "less experienced/skilled" ICT Technician this way, but we'll give it a shot! Thanks again- any other comments are most welcome! Paul

RE: [suse-linux-uk-schools] Tricky DNS Problems
by Chris Puttick 12 Mar '03

12 Mar '03

You lie to it... If you put an entry in your DNS for smtp.freeserve.net CNAME mail.ourschool.sch.uk, then your DNS server will return that information. However, if your specific example is indicative of the others, then use the hosts file on the local computer to get a similar result. The webpages are best dealt with by Squid/Squidguard or similar. What does your primary proxy do now? Chris -----Original Message----- From: Rob Keeling To: suse-linux-uk-schools(a)suse.com Sent: 3/11/03 6:44 PM Subject: [suse-linux-uk-schools] Tricky DNS Problems I have currently got Bind 8 and dhcpd working on a suse 8.1 server. All of our clients now use this machine as primary DNS. The bind config is set to be authoritive for our own domain, and forward all other requests up stream to EMBC`s name servers. What I now want to do is "poison" the DNS cache with various entries for other (random) domain names. eg My laptop wants to send email to smtp.freeserve.net, which is right for home at school I need it to connect via our school email server. If DNS returned our internal IP for smtp.freeserve.net ..... problem solved!

selective archiving
by Mike Rees 11 Mar '03

11 Mar '03

Hi Any idea how I can selectively backup certain type of files using tar (or otherwise) For example, (don't shoot me for this) *.doc, *.xls, *.pub files. I'm trying to backup users home directories which inevitably contain loads of cr4p making the size of the archive balloon. This is the kind of thing I'm using currently. Obviously, repeated for each directory and filetype I want to backup. tar -cvf backup /etc /usr/bin/find /export/home/ -name *.doc -newer /etc/last.backup -exec tar -rvf backup {} \; The script is getting longer and longer as I add new filetypes. Am I missing something obvious? Can I feed find or tar multiple arguments ie the file types?

Test for prospective employees? OT

Hi there. I'm wondering if any of you can help me? I have been delegated with the task of formulating a test of sorts for prospective ICT technicians (2), and though the school now runs some sort of testing itself (though I don't know what they do yet) are there any suggestions as to what I can do? Have any of you been to an interview in a school for an ICT position, and if so, what did you get "tested" on? Are there any web sites that give templates for tests etc? Just wondering. Thanks, Paul

iptables question
by Matt Williams 10 Mar '03

10 Mar '03

Morning We currently have 2 linux gateways within our school, one is for the broadband by provided by our council, the other our old isdn line. In true council fashion the gateway they provided us with will not do anything other than browse the web. We have set all clients (windows 2000) gateway to point at the council ip address. Is there a way I forward all requests that aren't on port 80 (or 443) onto the other gateway? All example I see for iptables seem to be routing through different interfaces on one card. So for example if the bb gateway is 172.16.0.20 and it receives any requests that aren't on port 80 to forward these requests onto 172.16.0.5 (isdn) to use that gateway for these services. Can this be done? Cheers Matt

MySQL

Folks, I've searched for help in seemingly more relevant places, but I have a suspicion someone here will at least point me. I've googled, search the manual, read heaps of tutorials (devshed etc) but I don't know what to *call* what I'm after, so it's very tricky. Could someone direct me to a tutorial or example that deals with rearranging shown below MySQL... Or at least give me the *jargon* for what I'm trying to do. I don't think it's a cross tab or pivot table, as they seem to sum data. I have this table: name week score joe 1 30 fred 1 23 rita 1 33 joe 2 31 fred 2 24 rita 2 31 And I just want to display it like this... name week1 week2 week3 joe 30 31 fred 23 24 rita 33 31 What do I call that please?

CMIS admin under WINE
by Chris Puttick 07 Mar '03

07 Mar '03

Now here's a good question... One of the schools we help support are looking at moving wholesale to Linux thin/fat client.However, they have just moved to CMIS, and have an administrative PC in each classroom. The school feel these PCs must be able to access not just the eportal, but the CMIS Admin program as well. As far as I can ascertain, this is just an exe that runs off the server and requires no installation. The question: has anyone tried running this under WINE? Cheers Chris
