schools needed for filming
by Kate Hanaghan 13 Nov '01

13 Nov '01

Hi all, We're looking to do some filming at a school that is running Linux or open source software on school equipment. We've already been up to Yorks to see Silcoates, which was great. But we need a couple more schools to make the programme complete. If anyone is interested or knows of any school that might be, do drop me a line. The finished programme will be available on our website. Thanks Kate Hanaghan Ebusiness editor Silicon Media Group +44 207 761 8219 http://www.silicon.com

NYC High Schools
by Ruben Safir 11 Nov '01

11 Nov '01

What kind of programs does SuSe have for HS's in the NYC area? I'm looking at making a large effort to get linux into schools in the Brooklyn area through NYLXS. Suse is my favorite distro so... I was suprised to see this mailing list. I hope we can be your feet on the ground in this area.

SuSE 7.2, RedHat 7.2 speed
by Matt Johnson 09 Nov '01

09 Nov '01

Michael (and all), Erm, sorry - since reinstalling SuSE7.2, StarOffice is running equally quickly on either distro. For some unknown reason, it wasn't before, but now, on a clean install, it's right as rain. Thanks for your answers - I learnt something about how it all hangs together while trying to solve it. Cheers -- Matt __________________________________________________ Do You Yahoo!? Find a job, post your resume. http://careers.yahoo.com

D Link DFE570TX 4 port network card
by Phil Driscoll 07 Nov '01

07 Nov '01

On the advice of this list, we recently purchased a D Link DFE570TX 4 port network card to use in our new Linux server to give us loads of network bandwidth to the machine. The card is fitted and working great, and I can imagine various schemes to exploit the four interfaces. Can anyone advise on the best way to do this? For information, the server is essentially using Samba to impersonate an NT domain controller which provides authentication and data storage for all staff and pupils. Client machines are mainly NT workstation, although there are about 30 Risc OS machines, and will shortly be 100 or so LTSP Linux boxes working to another server (or servers) which will also rely on this server for storage and authentication. Sadly we only have one 24 port switch and shed loads of hubs. -- Phil Driscoll

Re: CCNA & SuSE 7.3
by Paul Munro 05 Nov '01

05 Nov '01

As someone who had to take a CCNA to keep my job, I would say that I agree with the last assessment of their worth. CCNA and all other related exams are merely a peek at whether you know the Cisco way etc. The test I took was very easy--in fact, nothing like I had been warned of or imagined :-O On a separate note I was considering Red Hat 7.2 this week, but someone here mentioned it had problems with ext3 etc., has anyone had any experience with 7.2; and the other question is: is SuSE 7.3 any good (don't know if I should ask this on a "SuSE" list ;-) Thanks!

RE: [suse-linux-uk-schools] D Link DFE570TX 4 port network card
by Chris Puttick 05 Nov '01

Strictly speaking, trunking is a reference to VLAN capability, based on the telephony concept of a trunk line. The term normally used to describe grouping multiple physical network interfaces as a single logical network interface is channelling (port-, ether-, -aggregation), depending on vendor. BTW, Cisco see the CCNA as a GCSE/AS level. Rate people with this qualification appropriately. To compare with an MCP or A-level (not that I'm suggesting an MCP is an A-Level - more KS4), see the CCNP. To compare with a degree/masters, see the CCIE.

With some SMC switches at least, you can designate two or four ports to be a "trunk", connected either to another switch, or to a multiport NIC. That would give you an 800Mb/s full duplex pipe between your server and the switch. The kiddies could have some fun trying to saturate that!

DLink Card
by Paul Munro 05 Nov '01

05 Nov '01

Hi there. I know something of this from my Cisco training. Firstly, your card probably does support link aggregation, and what this means is that simply you can share the load of data coming into or out of the card at any one time. How you implement this is sometimes down to proprietary protocols, and sometimes not so much the protocols but the hardarwe and the type of switch involved (such as a Cisco 29xx XL). What you normally need to watch for in such cases is looping (as someone here also stated before my post). When you don't implement the STA (Spanning Tree Algorithm) to designate root ports etc on your switches, things tend to lose their way around the LAN, get repeated, and generally cause lots of pain! STA stops this, and though needed at the switch (not at the card), it may be worth looking at this thought its not terribly important for your set-up right now. With "trunking", you are probably best using two lines for data access and two for redundancy; the server would be able to guarantee a certain level of service this way--and again, how you do this will be down to the individual switch manufacturer, type of switch and your Linux configuration etc. Personally I would aggregate the links and see what kind of throughput I'm getting at peak times; use a good analyser and find out if there are any problems, and watch for loops (though I doubt you'll have a problem there anyway).

Trunking is an accepted term used (or understood) by most manufacturers. Switches varyin their trunking support - some need the IP adresses to be identical across the trunked ports, some need different, others seem to reject anything other than a second trunked switch :( My own (painful) experience says: try it when things are quiet, but you'll need a few volunteers to test the configuration - trunked connections occasionally work perfectly until the first trunked channel is saturated, then take the whole network down. Good Luck.

Linux in Schools Workshop
by SILCOATSIT＠aol.com 03 Nov '01

03 Nov '01

Hi everybody We are running a workshop on using Linux at Silcoates School, Wakefield West Yorks. On 2nd of November and still have a few places left, if anybody is interested. The day is aimed mainly at people who are thinking about deploying Linux in schools and want to see it in action with maybe a short session on LTSP and the new StarOffice 6 depending on demand. Below is the text of a letter we sent to Independant Schools in the north of England. So if anyone is interested please get in touch. John WIlson Using Linux and other open source programs in schools For two years Silcoates has been running its teaching network entirely on Linux servers. The system is reliable, versatile, and powerful and has proved its worth in that period. We are now offering a one day introductory course on the use of Open Source software in place of proprietary commercial systems, open to people from any sector of education. Here is a chance to acquire first hand knowledge of open source systems within a working school environment. You will be given the opportunity to share what we have learned about Linux in practice and try our systems out for yourself. The course will pre-suppose no specialised technical knowledge, but anyone who wishes will be able to discuss technical issues with those responsible for the system. We will be focussing on Linux as a server platform (using Windows 98 clients), but we will also be offering a chance to try Open Source applications software in the form of Star Office (which can run on Linux clients as well as Windows machines). Depending on the response to this initial venture, we hope to offer more detailed courses in the near future tailored to the specific needs and requirements of those interested in moving their own installations to Linux. There are further details of the use of Open Source software at Silcoates, giving some idea of the areas we will be covering, at http://linux.lexilog.org.uk/ The course will take place on Friday, 2nd November and will start at 10am. Lunch will be provided. If you wish to attend, please fill in the form below and send to Les Brown, Silcoates School, Wrenthorpe, Wakefield WF2 OPD, enclosing £15 per person to cover costs and lunch.
