This is the automated ALUG IRC meeting reminder sent to remind you that there is an IRC meeting tonight (Monday) at 8.00pm. The meeting takes place on the irc server irc.alug.org.uk in the #alug channel. Most IRC clients should allow you to get there with the commands "/server irc.alug.org.uk" and "/join #alug". Popular IRC clients include tkirc, bitchx, xchat and EPIC on Unix, and Mirc under windows. Here are some links to help you get started with irc. Unix http://www.xchat.org/ http://freshmeat.net/ http://www.epicsol.org/ Windows http://www.mirc.com (loads of help with irc for newbies!)

I hate to be picky, but wouldn't the education authority or whoever is paying for all this stuff have some kind of problem with you inviting all and sundry to use their network (which presumably contains sensitive information)? If I was the headmaster, the "number of restrictions you need to be made aware of" would include "Connect anyone to this thing without my express permission and you're fired". In last year's UK Networking Industry Awards, of which I'm one of the judges, one of the entries was an educational establishment that was very proud of its new wireless LAN installation. Sadly, at no point did the entry blurb (which was many pages long) include terms like "security" or "encryption" - in fact the implementors were proud that you could surf outside the school buildings on your laptop. They didn't win. By way of a footnote, it's interesting to see how many companies don't turn on security by default. At the Networks Telecom Show at the NEC last June, a friend of mine who runs a super little security product dealership/consultancy was showing me his new toy - a wireless LAN analyser from Vernier Networks. We stood in the middle of the NEC identifying literally dozens of insecure servers on this thing, because the vast majority of exhibitors didn't have security turned on in their wireless installations. Not a problem at a trade show, you'd think, but you must remember that many stands have phone/ISDN links back to the main office, thus giving any old muppet with (in our case) an iPaq and a few hundred quid's worth of software a really nice route into their corporate networks.

Absolutely correct. Ionica launched back in the mid 1990s, when I was tech ed of Network Week. From day one we were basically writing things like "Neat idea, but the guy running it sounds like a cowboy and they've forgotten to do any marketing". When we asked Ionica whether we could have anything more than a phone line - ISDN, for instance - the answer was always that the current equipment, running in the current radio spectrum (2.4GHz, I believe it was), couldn't handle it but when the new version came out (11GHz or so, if memory serves) we could have anything we wanted. To say that you can't do 128Kbit/sec ISDN in a 2.4GHz spectrum is, of course, nonsense - if nothing else you could mux it like cellular providers do with multiples of 9.6Kbit/sec channels in GPRS. It may have been fair to say that the kit wasn't up to it, but I can't imagine the equipment vendors didn't have an upgrade roadmap. Interestingly, the Ionica service - where it was available - was excellent by all accounts. You could have multiple numbers with a different ring pattern for each (so dad could have a different ring pattern from mum), caller ID, a 1471 equivalent, and so on - they did all of this long before BT. And the coverage area was okay, if not massive. From what I can see, they just didn't spend the marketing bucks, and got a reputation in the press for being a bunch of wide boys trying to take investors for a ride. In fact there's still an Ionica receiver dish on a house up the road from me - maybe they're hoping the service will come back one day!! Regards, Dave C

How do I find an upgrade, assuming one > is necessary, to fix this? Or is there another remedy? You might very well want iptables instead. I can't see how a packet filter will help you talk to your Acorn, though... -- http://www.greenend.org.uk/rjk/

I have just started playing with wireless stuff at work and it's great to be able to wander around with a laptop my boss loves it. I work at Framingham Earl High School As the Network Mangler and would love to help out if I can. We have a 2mbit DSL connection going unused during the evening. This would be fine for general web surfing but there are a number of restrictions that you need to be made aware of. If anyone wants to experiment let me know. Maybe we should have a wireless antennae building session etc... I have a couple of waps and pcmcia cards at work. Cheers, Ben

Having said that you don't have to use shorewall, you can write your own script if you wish. Regards Andy
