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

Depends, what's Mandrake 9s default kernel? if its in the 2.4.x series then there is no spoon^Wipchains unless they're being very silly. iptables may be available. Certainly on debian systems unless you let it actually install stuff on the initial setup you have to install the ipchains/iptables packages, so, maybe you managed to do a minimal install of Mandrake... Anyways - just my thoughts at this silly time of night. Brett.

Newbi problems
by ALISTAIR MACGREGOR 17 Feb '03

17 Feb '03

Hi I wonder if any of you gentlemen or ladies can help. I'm a new user and by new I mean new. I installed Mandrake 9 on Friday (14th Feb 2003), after weeks of having nothing but problems frow my Windows system. So far (Only two days I know) I've had no problems, except one. I seem unable to access my floppy disk or either of my two CDROM drives, I know their there, I formatted a floppy disk and saved some files there. On trying to retrieve them i was told I "Do not have permission to access the files" or something along those lines. On opening the Home directory and going through the files to arrive at the /mnt folder, I was again told that I had not the relevent permission to access my files, looking at the floppy properties, I saw the 'owner' and 'group' listed at "root" Logging in as root, giving the password I entered at install, I was told again .......well you get the idea. Any help would be greatly appreciated as I need to edit the file and do not wish to re type the whole thing. If it helps my system is a Packard Bell Club 600 with a Celeron 600hz CPU, 1 DVD/CDROM, 1 CD writer, 128mb ram, 13GB HHD, solely for Linux. On board graphica and sound. Alistair

Should I > > make the effort to implement FTP or take desperate steps to avoid it?" Not often I post to the list, but what the heck? FTP vs. HTTP is your classic "Horses for courses" discussion - one is better than t'other for some situations, and not as good for others. For example, HTTP is great if: 1. You want to let people download single files via hyperlinks on a Web page. An HTTP link is just a link to a file, which when clicked will make the browser download it. 2. You want the client browser to open the file (e.g. a PDF or Word doc) either via a plug-in or an external application. HTTP stamps each file (or each section within a multipart download) with a MIME type, which the browser can use intelligently. So if my Internet Explorer or Netscape spots that it's a PDF document from the MIME type, it launches the Adobe Acrobat Reader plug-in. If it sees a Bloggit document and doesn't have a Bloggit plug-in, it simply launches the application under Windows and passes the filename to it for opening. This is much harder to do with FTP - it basically depends on the client machine being able to use the file extension (e.g. .PDF, .DOC) to map it to an application. 3. You have a Web server and you don't want to muck about setting up FTP. Many machines come with HTTP set up out of the box but not FTP. And if you want to set up anonymous FTP you have to be dead careful you don't open all manner of security holes. 4. People using your site have firewalls that have a hard time with FTP connections. Most of us understand that sometimes you have to switch your FTP client to Passive mode if you're behind a firewall, but many people I speak to (i.e. who say "I can't FTP this file") don't realise this, which can be a pain. FTP is great if: 1. You want to download multiple files. There's nothing quite like an "mget *" to make life easy when you're downloading (say) the 15 patches for your kernel that have come out since you last patched it. 2. You want to allow people to upload files. You can use HTTP's PUT command, but it's nothing like as easy to work with as an FTP PUT. 3. You want to enforce access control depending on user ID & password. Although you can do access control with an HTTP server, it's far from elegant in most cases, particularly if you want it to integrate with the user database (or global directory service) on the server computer. FTP servers, on the other hand, tend to be easier to fly in this respect, and generally integrate much more tightly to the OS's user database than would be the case with an HTTP server. I'm not saying you can't do it with HTTP, just that it's not as elegant in the average case. 4. Your clients have intelligent FTP clients. Ever tried FTPing from (say) a Red Hat 7.2 box to another Red Hat 7.2 box? Do an "mget *" and the server will tar and gzip all the files into a single compressed archive, then send over that single archive; the FTP client will unbundle everything and leave you with a file structure like the one it started with at the other end, but with a far more efficient transfer in the middle than would have been the case with numerous files (particularly if the files were small). At the end of the day, there's not a lot you can' t do with FTP that you can't emulate with HTTP, and vice versa. For most of what we all do, I suspect that HTTP will outnumber FTP in the majority of cases, because we don't do anything particularly complex in most of our sites. The only situation where I use FTP on my servers, for instance, is where people rent space on my server for their home pages, and they use FTP to upload the pages. Everywhere else I use HTTP, mainly because MIME typing lets the client browser be clever about what it does with documents. D.
