It blocks malicious, and sometimes not particularly malicious, contact from the web to your computer. Zone Alarm is a fairly good free version, if you don't have Windows XP sp2 or better. If you do there's one built in to your OS. Someone else will have to tell you how to activate it. I don't have anything running that doesn't require more than Windows 2000 and I's hates XP I does... If you need Zone Alarm you can download it from them for free here: http://www.zonelabs.com/store/content/company/products/znalm/freeDownload2.jsp They'll ask for a valid email address and bug you with product offerings from time to time...

Re: OT LOL - What's a Firewall?
If you're running Mac OS X ... Open System Preferences. Click on the Sharing icon. Click on the Firewall tab. Click the Start button. This turns on the personal firewall at the client computer. A firewall at the network is also useful to block access to network- reachable computers and peripherals connected to your network, but for networks with no other devices other than a computer and a printer attached they don't do much of any consequence. If you have several computers on the network and/or have them configured to share files or allow remote operations, then a network firewall is essential to security. Most important if running a wireless network is to turn on encryption in the wireless base station. If you don't, you are broadcasting any information you transmit across the network connection as clear text that can be captured by anyone with a receiver and an application that can capture network packets.

RE: OT LOL - What's a Firewall?
A firewall (one word) is a computer program (which could be implemented in software or hardware) which automatically prevents unauthorised access to a computer that's connected to a network. To connect to a computer you can use so-called ports. These can be real (for example, a parallel printer socket) or numbered virtual ports. When you connect to the internet you are typically connecting through one or more virtual ports, each of which may be dedicated to one or more well-known functions. For example, browsers use port 80, and outgoing email usually uses port 25. A firewall prevents anything other than the specified functions from using the ports - this is called blocking the port. Normally firewalls give you several configurations of blocked and unblocked ports from which you can choose. Or you can set your own configuration. As others have mentioned, you can use the firewall supplied by the operating system, or use one built into your modem (if there is one built in). I use the firewall that's built into my wireless modem/router. Normally those built into a modem are considered to be better than those supplied by the operating system. I've never examined this claim, but just take it on trust. The benefit is that it protects your computer from unauthorised access (hacking). The cons are that it's a bit of extra cost, either as money or cpu cycles or both. You can get one from a computer store if you don't have one built into your modem. Check the documentation in your modem first, but if you're still using dial-up, chances are you don't have one. If you're using XP and are patched up-to-date you're probably using the Windows Firewall already. http://www.microsoft.com/windowsxp/using/security/learnmore/atkin_firewall.m spx -- Cheers, Bob -Original Message- From: Shel Belinkoff [mailto:[EMAIL PROTECTED] Sent: 12 May 2006 16:36 To: pentax-discuss@pdml.net Subject: OT LOL - What's a Firewall?

Re: OT LOL - What's a Firewall?
If you have XP sp2 installed the firewall is already up and running. If you combine this with Windows automatic updates (free), microsoft windows defender (free) antispyware and any antivirus client (norton, mcafee or others) you should be fine. Any other additional security tools only create additional overhead resulting in a slow PC.

Re: OT LOL - What's a Firewall?
I read about hardware firewalls all the time. I would like to see one sometimes. The best I have come across is firmware, that is implemented in PROM so hackers can not change it. I suspect that is what folks really mean when they talk about a hardware firewall. And even that makes it kind of hard to open a port for something like your p2p program. There are now thousands of TCP/IP ports but most folks only need a half dozen or so, a firewall blocks access to the others. Of course only brain dead OS like windows really need firewalls as with UNIX you can disable those you do not need right in the OS. Of course Paul's firewall is truly a hardware firewall, as is the one between my appartment and the next grin. graywolf http://www.graywolfphoto.com http://webpages.charter.net/graywolf Idiot Proof == Expert Proof --- Mat Maessen wrote: On 5/12/06, graywolf [EMAIL PROTECTED] wrote: Oh yes, a firewall is a piece of software that blocks all but a certain necessary few network portals.

Not entirely true, if you install software that has spyware as part of the install you really want to know about it. There are also so called zombie programs that you can accidentally installed which become apparent when they try to phone home and your firewall informs you of the attempt.

Re: OT LOL - What's a Firewall?
Wrong. A classic security violation is a Trojan Horse program (or image, or ...) that, once inside your barrier, opens up a pathway to the outside world and downloads all sorts of unpleasant stuff. That's how a lot of spyware, adware, etc. gets installed. I've got a NAT box to isolate me from the outside world, but I still run firewall software to monitor all attempts at connections, even if originated on my computer. I'm amazed that anyone would consider using a home computer connected to the 'net *without* having firewall software installed. Almost as amazed as I am that somebody could own and use a DS for months without even knowing it could be put into full manual mode, but that's another topic :-) On Fri, May 12, 2006 at 04:32:08PM -0400, graywolf wrote: It is not what is trying to get out that you have to worry about, it is what is trying to get in. graywolf http://www.graywolfphoto.com http://webpages.charter.net/graywolf Idiot Proof == Expert Proof --- mike wilson wrote: graywolf wrote: Well if you are running Windows XP Pro SP2 you go into the Control Panel, select Security Center, click Windows Firewall at the bottom of the panel, then click On.

Yes, it certainly is another thing, John. I knew the DS could be used in full manual mode, but I did not know that it could be done with an auto focus lens.

Re: OT LOL - What's a Firewall?
I still say that if you get hit by a trojan horse program it is your own damn fault. Nothing I download is opened or goes out of the download folder until it is scanned for viruses, spyware, etc. If I forget it is not someone else's fault. That does not mean that some smart guy somewhere can not hack your box, if he does that is not your fault. But if you bring the thing in the door yourself it sure as hell is. graywolf http://www.graywolfphoto.com http://webpages.charter.net/graywolf Idiot Proof == Expert Proof --- John Francis wrote: Wrong.

Re: OT LOL - What's a Firewall?
Hi Shel, A firewall is a piece of software that controls the ins and outs between your computer an the internet. The software can reside in your PC, or in a separate box like a broadband router or Wireless network access point (WLAN). There are many varieties of the PC residing kind. If you have Microsoft Windows XP, there is a firewall built into ServicePack 2 which can be downloaded from Microsoft free of charge. Another product is ZoneAlarm, which also has a free version, IIRC. Many of the Antivirus software packages also ship with firewall software, eg. Norton and F-Secure. Usually, the software packages defaults to a setup that allows the most common types of traffic, like mail, FTP and web-surfing, while blocking the rest. A good software should give you warnings each time a program on your PC tries to reach out to the internet, whereupon you can grant or deny. Either on a permanent basis or from case to case. hth, Jostein - Original Message - From: Shel Belinkoff [EMAIL PROTECTED] To: pentax-discuss@pdml.net Sent: Friday, May 12, 2006 5:35 PM Subject: OT LOL - What's a Firewall?

Re: OT LOL - What's a Firewall?
I'm amazed that anyone would consider using a home computer connected to the 'net *without* having firewall software installed. I don't know, I've never seen it as *that* necessary if you just connect one computer directly to an ISP. On such a setup I wouldn't have any services activated anyway, so nobody would be receiving the bad network connections (and there is no need to block them.) But I'm generally not using MS Windows... If you your have your own network of computers that need to talk together it's a completely different situation. Maybe it's been mentioned already, but a firewall's job is not just to block network traffic, but to block traffic from the wrong people/computers/programs while still letting data from others through (or technically, it's the other way around most of the time - you let through information to or from specific machines or programs, and stop the rest.) - T

And I'm not sure that feature was available with firmware versions earlier than 2.0 Oh, indeed it was - with the original firmware, on the first DS shipped. Just as it was on the *ist-D, right from the first day. Those cameras were designed to work with AF lenses, but they've always offered a full manual mode (together with Av, Tv full Program modes). It's described in the manual on page 138-139. And, more to the point, there's an M marking on the Mode dial on top of your camera - that didn't get there as part of a firmware upgrade, and it's a bit of a stretch to suggest that the mode, and the marking, are only for backwards compatibility with old lenses. In addition, as has been mentioned here, many times, any lens off the A position behaves just about the same as a pre-A lens, and will function in the Hyper-Manual mode (using the AE-L/Green Button triggered metering). That, too, was available on the DS right from the initial release, and is also described in the *ist-DS manual. (The first *ist-D firmware didn't implement the green button stop-down metering for the pre-A lenses, but that was well before the DS arrived).

[EMAIL PROTECTED] wrote: The firewall goes right behind the engine. It helps prevent your toes from getting toasted when you overrev and blow your mill. vbg :-) Seriously though, a firewall is a piece of hardware that goes between your computer and its network connection (usually cable modem or DSL modem). A firewall performs what's called NAT or Network Address Translation so that it can isolate what's Out There from your computer. Most consumer routers fall into this category. You can get one for under $40.00 these days. There are also a lot of software apps available that bill themselves as firewalls and emulate what a hardware firewall is supposed to do. They're better than nothing, but anything that's implemented in software can theoretically be circumvented via software (read: virus). I wouldn't dream of connecting my computer to the 'net without a NAT firewall box in between. (I'm using a Linksys router.)

Re: OT LOL - What's a Firewall?
Off on broadband.com is a test that will check what can get trough to your computer. Along with several other interesting tests including just how fast your connection actually is. Yes, Bill, XP's firewall seems to work just fine, but it only protects the machine it is running on. I am going to be a bit snippy here and suggest that some of you out there spend some quality time with a TCP/IP networking book instead of reading the boxes at the computer store.
