From: Andrew Hooper For : The Editor (for publication) Subj: DOS Attack on DSL Last Friday I contacted my ISP with the concern that I was experiencing heavy lag via my Jetstream connection, Saturday they replied that it was due to an outage at telecom and that things would be back to normal soon. Today I decided to take a look at my usage report, on average I use 400MB Max per month, imagine my surprise when I found it was close to double that, I'm on a 600plan so usually have a 200mb safety zone. Upon further investigation I found that while I was out today my Jetstream connection received several large packets, both were around 58MB, and both were received consecutively. The contact I had with telecom confirmed that there was no network problems and that this may have been a DOS attack on my IP, The informed me that there was no way of stopping this other than turning my router off and there was little if anything I could do, However because I'm a home user I can change to Jetstart. They also would no reverse the charge for the additional MB used over my allowed amount, No I realise that this is not much, BUT I really don't think that this is fair on the users of Jetstream. Telecom offer NO protection against this, They admit that they can not log or trace the offenders, and there is no software that can detect a DOS attack unless you pinhole all ports on the router to the machine with something like Zonealarm on it, but then you cause problems for other machines on your network. So Telecom continue to have their cake and eat it.

So Telecom continue to have their cake and eat it. Why is it that every other ISP can track DOS attacks but Telecom don't?. Under the Consumer Gurentees Act do I have to pay for data I did not request or did not want to receive this data. From: Joe Dydowicz For : The Editor (for publication) Subj: RE:Turn Off That DSL Modem! Heres another shock for you, and one of the reasons I dumped Jetstream DSL (JS) (besides the huge price tag)..Turning off your modem DOSEN'T do any good. I had a long talk with a Jetstream tech and the data that is coming into your JS connection is counted WAY before it ever gets to your modem/system. The 'node' or 'switch' whatever you want to call it that connects you to the internet (on the 'other side' of your ADSL modem) is what counts your traffic, if you turn off your modem that 'switch' STILL recieves data coming into your connection and is thus still counted. The only thing turning off your modem does is prevent you from getting it but its still counted. From: paul For : The Editor (for publication) Subj: DSL in NZ its obvious, telecom got with the times - who else in the world offers "128k dsl" with pay-per-megabyte charging. i could understand it, if it was maybe a 2mb connection. i moved from the nz to the uk, and the lowest connection you can get where i am is 512k. my isp use to have a bandwidth 'cap' - 700mb a day. its unfair of telecom to expect users to pay for data they did not request. but we aren't surprised are we? is telecom the only one offering dsl there? don't telecom have to allow other companies to offer dsl like over here with BT? ps: hi andrew :) From: Fran McGowan For : The Editor (for publication) Subj: Webserver from dial-up An incorrectly configured Personal Web Server (IIS Lite)- eg. from Frontpage or other Office packages could let you in for this. From: James For : The Editor (for publication) Subj: Linux on your desktop I have been using Linux as a desktop now for 2 years and believe me it works. The reason that companies have not taken the plunge with the penguin; to do so costs them nothing, or very little. The management can't believe that if you don't pay for something you get crap. It is the same as paying megabucks to an external consultant that tells them something one of their own employees could have told them for 'free'. Which report do they believe? Why the one that cost them lots of money. I don't know why everyone is suprised about Microsoft's dominance. Remember their used to a computer company called IBM. It was said that you never got fired for buying IBM. The same seems to be true of Microsoft. Perhaps if the Board of Directors could understand the techno-babble spouted by their head of IT as he ducks for cover over the latest breach of security in Microsoft software, they would sack him and buy Linux. From: Geoff McCaughan For : The Editor (for publication) Subj: Linux on the Desktop The reasons for slow Linux desktop uptake are: 1) Inertia. M$ knows that if they get their OS onto PC's at the time of sale, most people will leave it there, hence their strenuous efforts over the years to ensure that vendors ship windows with every machine. Your average PC buyer isn't savvy enough to consider installing a new OS. This is exacerbated by: 2) FUD. Everyone has heard the 'Linux is hard to learn/install/use' stories. Joe public thinks Linux is for geeky propellor heads who write new kernel code in their spare time. These FUD stories are still circulating around and can be found in the media even today. As anyone who has installed both can tell you, installing Linux is no more of a chore than installing Windows. The reality is vastly differentfrom the FUD. Installing and using a modern Linux distribution is a breeze. Sure it's possible to have problems with some esoteric hardware combinations - Windows has these sorts of problems too. The big win comes when Linux is installed and running - it's *very* stable. No need to reboot all the time, no need to reinstall the OS because something trashed the registry, no need for eternal virus/trojan paranoia [though new users would do well to check with someone experienced to ensure their setup is secure], and no need to fork out a pile of $$$ next time M$ decide you need to 'upgrade'. You can even run windows applications under Linux if you really need a windows application and can't get a Linux equivalent, and you still benefit from the Linux stability and robustness. From: Grant For : The Editor (for publication) Subj: Linux on the desktop I thought I would give Linux a bash recently. I installed Red Hat 7.1 that came on the cover of an Australia computer magazine (total cost = $10), and settled for the KDE interface (more Windows like). I also kept my Win98 installation on the primary drive. I am really impressed - the install autodetected everything, a internet connection was trival to set up (Ihug & Xtra were already listed in the dialer setup) and Konquerer web browser & Kmail work well. Given that it comes with games, KOffice, drawing/image editing package, development tools I think it works out at least $1000 cheaper than buying Win2K and Office 2K retail. Yes, Linux does need more good quality apps (I am struggling to find good preschool software for my children) but for average home computer useage (web/mail/games/MP3's etc) Linux is just about there already. From: Allister For : The Editor (for publication) Subj: Why no Linux Desktop? So, have you tried installing Linux lately? Let me give you a tip. If you have a "package deal" machine, like my HP Pavilion, then DON'T install Linux. Sure Windows has its problems, but by and large a reboot will fix, or the machine may just keep working at reduced capability. Putting Linux on takes the problems to the more basic level. My on-board graphics card is crap apparently. It turns out that when W98 says the refresh rate is 60Hz, it is actually running at 59Hz (verified by the monitor itself). So when Linux trys it at the "standard" 60Hz, the display breaks up - worse when a device is active, like disk or mouse. Ever tried reconfiguring monitor modes under Linux? Not for the faint hearted. My modem isn't real - it's a Winmodem. Good luck getting that to work on Linux. I got a new, external modem. Linux detected it and now says it won't respond. Huh? My sound card is auto-detectable, but still refuses to work anyway. The only reason I got as far as I did is because a colleague has it installed and has done enough surfing and reading that he knows how to surmount a lot of the problems - mostly by knowing which obscure command is needed to do the job. When Linux gets more automation and more information, then I'll consider it. For now, it is a tinkerers dream.Now Have Your Say
