IP Calculator that is Easy to use.

While I can calculate the IP address and blocks using paper, the question that I always ask is, Why?

This free calculator lets you easily play with numbers, arrange IP Addresses, and sort the networks that are used or needed.  I use this tool extensively and would recommend it to others as well to add to your tool chest.

You can download the calculator Avanced IP Address Calculator.

Compression to the Max on Windows

Compression has been around for ages, and the standard for windows has been defined using WinZip. That is until now!

Some time ago the new compression format 7-zip was released, giving better compression, and better security. I have started using 7-Zip as my compression engine for some time, and the compression and performance increases are worth it.

If you have a multi-core system, 7-zip for windows will utilize both of the CPU’s during compression. Overall this definitely is a great replacement for WinZip.

You can obtain 7-Zip from here:   7-Zip

Firefox Plugins

Well I decided that I will share with everyone and at the same time document for myself the plug-ins that I use for Firefox and what they do.

AddBlock Plus – This plug-in is useful mostly on Linux version of Firefox for me as for the Windows end I use my firewall [Outpost Firewall] to block all associated add pages with the words in it. This plug-in is a wonderful thing for those people that do not have outpost firewall or use Linux.

Deepest Sender – a very nice plug-in that open’s up a window that you can blog from, and lets you do formating and posting for various blogs.  I am using it now in fact!  The only bad thing about it, which I have to submit to them and I have on my To Do List is no multiple categories.

Download Embedded – For that time that you really want to go grab the embedded graphic, movie, sound, etc., this is is the plug-in that gets it done.

Download Status bar – Simple bar that opens up downloaded boxes and the status of download instead of a separate download window.

IETab – For those times that you must use IE, there is no point in opening a separate window, this plug-in lets you open up pages inside Firefox Tab.

Tab Effect – Want some WOW factor? This plug-in just creates a rotating cube inside the browser. While not the same as XGL in Linux it is a nice little effect that runs in any Firefox environment. Now if only XGL ran on windows!

There are a few other plug-ins that I use from Google, but they take up their own posts later on!

RSS Reader for Windows (Feed Demon)

I have been playing with the Demo of a pretty good RSS Reader software.  For a while I have been using the Plug-ins for Firefox called SAGE, and while it does provide the information within the Browser, it does not give me some options such as instant pop-ups at the bottom of the screen, ability to actually read some of the things off-line while I am traveling on the bus, and some minor things.  So i decided to demo this software, which gives you a lot of options that I was looking for and so far I like it.

Some of the Features that I like:

• Newspaper Format – Lets you display Groups in a newspaper format
• News Bins – Ability to collect items you might want to read again in News Bins for future reference
• Reading Articles in other readers such as Firefox
• Watches – Looking for Keywords in the news items
• Search Words by creating a dynamic Search Channel looking for keywords.
• Podcasts – tools built in to the reader to view podcats including scheduling of downloads.
• Plus many more!

I recommend you try it out for yourself with a demo available:

GAIM is now PIDGIN (a great Instant Messanging Client)

The GAIM project after a long time of playing Pin the Tail on the Lawyer … I mean a court and Letter writing battle has decided to just let it go.

As of the 2.0.0 version the GAIM project and product is now called PIDGIN. What does it mean to you, nothing as far as the great software is concerned. Same product, new graphics and a new name. This is actually a nice move as far as I can see as this will stop the legal headaches and lets the developers concentrate on making the software even better.

If you are not familiar with GAIM or as it is now known PIDGIN, it is the best Instant Messaging client out there. It is relatively light for a client that has ability to communicate to the following networks: AIM, Bonjour, Gadu-Gadu, Groupwise, ICQ. IRC Client, MSN, QQ, SILC, SIMPLE, Lotus Sametime, XMPP (Google Talk), Yahoo!, Zephyr. It also has ability for great plug-ins to compliment the environment.

The 2.0.0 product is not far away from the 2.0 beta product of GAIM as far as I can see. There are some additions of protocols it now supports, and it will be available for the same platforms as before.

After uninstalling GAIM and installing Pidgin in windows there was very little set-up that needed to be done as Pidgin grabbed GAIM information. Also there are plenty of plug-ins available for pidgin same as for GAIM.

For Gentoo Systems pidgin is available through portage although is currently marked as experimental (~x86)

Great Firewall for Windows

If you are using Windows then you have a lot of choices for firewalls. The bad choices is the built in windows xp sp2 firewall, there are others as well some good and some not so good (Nothing I tried is worse then Microsoft’s Firewall). But the best firewall in my opinion is Agnitum Outpost Firewall Pro:

Agnitum: Outpost Firewall Pro

This is a windows firewall that really is amazing for all skill level, it provides the basic functionality that my wife and kids can use, without asking many questions. But for a seasoned security professional such as myself it gives control options not found in any other firewall.

Lets first start with some of the plug-in applications that are provided by default with the firewall.

• Active Content Plug-in – Provides the ability to block, allow or prompt for various things. All of these things can be selected at a granular level with explanation available on each of the items Plus provide control that is different for Mail and Web.  There is also an ability to add total exclusions to the whole list for sites that are totally trusted. But even those sites that are trusted can still be controlled on a per item basis which is totally unheard off.  So for example your work E-Mail system has a virus that opens up  ActiveX or VBScript, but you being a savvy security person decide that you only want Java Applets or Java Script. No problem you can set-up exactly that on a per site basis. Here is a list of all the things that can be controlled:

• Privacy – Cookies, ActiveX, Java Applets, Referrers can all be controlled
• Page Optimization – Flash, Hidden Frames, Animated GIF, External Active Content
• Scripting – Java Script, VB Script, ActiveX, Pop-Up Windows

Sick of those Adds? No problem, the firewall has AntiAdd feature that allows you to block adds either by content (keywords) or from particular sites. Well this firewall does the Add Blocking for you. If you use the Firefox browser you can probably do something pretty similar by utilizing a plug-in. But you can not do it uniformly across all browsers, and programs that use the web as the content delivery mechanism.  A list of sites automatically is provided for you and can be expended by using different lists from the forums, but I personally like to delete all of them and only block the adds I do not want to see.  For example I do want to see adds from google because I find them unobtrusive and not taking up lots of space and bandwidth.   There is also the ability to block by size of the image, which Agnitum provided the most common add format when you do.  I find this feature actually a bit annoying, because it sometimes blocks images on shopping sites, but it can easily be disabled at a simple click or can be overwritten by using exclusion sites.  The adds list can be exported, and imported at will as well.

Anti Spyware – Yes I know you have a spyware program to do just that, but since it is a plug-in does not take up lots of memory and is updated frequently there is no reason not to add another layer of protection.

Attack Detection – I am not going to speak much on this as it is a simple attack detection theme. Perhaps this is where the firewall lacks a bit of the IDS functionality against other firewalls. It does not mean that it does not identify the problems, or let something through. It just does not provide the rich explanation of exactly what particular attack is being run against your computer.

DNS Cache – is simple DNS caching program which allows you to have totall exclusion for sites that have numerous rotating servers, such as a banking site.

Now lets get to the meat of the program, the program is one of the most flexible rule base firewalls ever. It does have a mode that advises what to do in each lf the categories.  The program gives advise to the beginner and opens up ports if OK is clicked, but for advanced users it gives tremendous options. The options below can be used in any combination that you want to provide very granular rules on a per application basis in any combination that you might want.

• Protocol  – TCP, UDP
• Direction of the connection – Inbound, Outbound, Transient
• Remote Host – Can be Domain Name, Ip Address, IP Subnet, Address Macros (which can be expended)
• Remote Port (Initiating port)
• Local Host
• Local Port (Destination Port)
• Time Interval
• Local Port – Allows connection on local port for remote port.
• Local Port is equal to remote port (automatically set -up)

For each of the actions the following methods are allowed:

• Allow Connection
• Block Connection
• Report it
• Run Application – Can be selected locally
• Do not log activity
• Stateful Inspection
• Ignore Component Control.

With such granularity on a per application, but we are not finished yet. There is also Anti-Leak protection and Component Control.   You can control a number of areas that I will not describe here, but basically this firewall can do everything you want.

I have been using it now for a few years, and every time I re-evaluate the firewalls I always come back to this one.

Take a look for yourself.

Anti-Spam for Windows

Since changing jobs I have to work with windows because it is the default build for the laptops. A shame to ruin a Centrino Core2 laptop with windows but what can you do.

So I will put down some of the great packages for those that are forced to suffer the same fate as me.

Program for Anti-Spam

The program is called SpamPal and you can reach it via the following web site:
SpamPal homepage:

The program is pretty small, taking up just 1448K of memory. In the program you enable Blacklist filters or (RBL’S) and then use the program as a proxy. This means you point your client to it with a change that is well documented.

The program will not delete any SPAM instead it will add Tags to SPAM messages so that you can filter them out via facilities of various E-Mail programs.

I like this program because it does not install anything within the Mail programs, and hence can be used anywhere and with any program. The only thing is that you can only use it for POP3 and IMAP.

Safe Flags for Intel Core Duo Laptop

Well a new laptop and another decision, what are the safe flags for an Intel Core Duo Laptop.  So a search all over the place for make flags for the system.  After a long search and not finding anything for my particular cpu set which is:

cpu family     6
model           15
Model name  Intel(R) Core(TM)2 CPU   T5600
stepping       8

Looking on the Intel site about this processor I found out that the T5600  and is a member of the Merom family.  When going back to the safe falgs web site above.

So not finding anything particular I come to this page:   Safe Cflags – Gentoo Linux Wiki, which I always start with to see if I can find anything.  All of the things are lumped together under the title of:

Intel Core 2 Solo/Duo/Quad (Allendale, Conroe, Merom, Kentsfield) and Xeon 51xx/53xx (Woodcrest, Clovertown)

As part of it 32 Bit is set to be:

CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"

Then immediately below it states that Intel recommends nocona for 32 bit as well, and a blurb about nocona might be slower then prescott.  So for now I set my make flags to prescott and will try to do a time trial with both settings compiling the same archive later.

In GCC 4.3 there is ability to set -march to core2, this is something to look at when 4.3 becomes stable.
