Untangle

Spam Blocking And Web Filtering With The Untangle 5.3 Network Gateway

Post date: September 4, 2008, 10:09 Category: Security Views: 7386 Comments
Tutorial quote: Untangle bundles common open-source applications for blocking spam, spyware, viruses, adware and unwanted content on the network in one single Linux distribution. It can be integrated into existing networks either as a router or as a transparent bridge (directly behind the router, but before the switch that connects the client PCs with the router). The best thing about Untangle is that you do not have to reconfigure the client PCs - Untangle works out of the box.

Enhance Your Mail Server With ASSP (Anti-Spam SMTP Proxy)

Post date: November 20, 2006, 19:11 Category: Software Views: 4204 Comments
Tutorial quote: ASSP stands for Anti-Spam SMTP Proxy. The ASSP server project is an Open Source platform-independent transparent SMTP proxy server that leverages numerous methodologies and technologies to both rigidly and adaptively identify spam. In short ASSP is the most kickass solution that is both free and works great. It reduced spam to an absolute minimum for me.

Build your own gateway firewall

Post date: April 11, 2006, 21:04 Category: Miscellaneous Views: 4898 Comments
Tutorial quote: Learn how to build your own gateway firewall using FreeBSD and old PC parts. The firewall will consist of the PF firewall, Snort IDS, various IPS applications, Squid proxy, and some intuitive web interfaces for auditing. The cost of this project should be between free and $200 depending on your resourcefulness. I built mine for free using spare parts that were stockpiled in personal storage and parts that the USMC was throwing away, but you can build one from used and/or new parts for dirt cheap.
SmoothWall

Install SquidGuard on Smoothwall

Post date: April 12, 2005, 18:04 Category: Software Views: 10728 Comments
Tutorial quote: squidGuard describes itself as: "An ultrafast and free filter, redirector and access controller for Squid". In my experience, it is the ideal web filter for use with Smoothwall and IpCop since it is lightweight and easy to set up. I use it on an i486, 33Mhz system with 18Mb of Ram and 500Mb of hard drive - and while there is a minor performance hit, the hit is not significant.

This simple how-to describes the steps I took to install squidGuard on my system - it should work for yours too.

dmcrypt

Post date: January 25, 2006, 22:01 Category: Security Views: 4281 Comments
Tutorial quote: Device-mapper is a new infrastructure in the Linux 2.6 kernel that provides a generic way to create virtual layers of block devices that can do different things on top of real block devices like striping, concatenation, mirroring, snapshotting, etc... The device-mapper is used by the LVM2 and EVMS 2.x tools. dm-crypt is such a device-mapper target that provides transparent encryption of block devices using the new Linux 2.6 cryptoapi. Writes to this device will be encrypted and reads decrypted. You can mount your filesystem on it as usual. But without the key you can't access your data. It does basically the same as cryptoloop only that it's a much cleaner code and better suits the need of a block device and has a more flexible configuration interface. The on-disk format is also compatible.

Hide your folders in KDE

Post date: November 11, 2007, 05:11 Category: Desktop Views: 3055 Comments
Tutorial quote: Want to keep your MP3s away from your boss’ or big brother’s view? Of course, in Linux anything that starts with a period is “suppose” to be hidden; but all we have to do is type “ls -A” or turn on the viewing of hidden files in KDE…not too hard. Basically what we can do is set a transparent PNG as our folder icon, and rename our folder with a ” “(space). This will actually keep the previous name of the folder.Also we will keep anyone out of the folder that doesn’t know Linux commands, and doesn’t know exactly where we have placed the icon. This works GREAT for the desktop.

Tutorial quote: Kernel 2.6.28 Released

Torvald released the final version of Linux Kernel 2.6.28. It's not a big change since RC 9, but it finally appeared as final after lots of discussion on LKML whether to postpone the release or release earlier and make the merge window longer as the developers goes on long holidays.

Here's some summary of Kernel 2.6.28 (taken from KernelNewbies): Linux 2.6.28 adds the first version of Ext4 as a stable filesystem, the much-expected GPU memory manager which will be the foundation of a renewed graphic stack, support for Ultra Wide Band (Wireless USB, UWB-IP), memory management scalability and performance improvements, a boot tracer, disk shock protection, the phonet network protocol, support of SSD discard requests, transparent proxy support, several new network drivers, controlable IO CPU affinity, high-resolution poll()/select(), support of a minimal "dummy" policy in SELinux, tracing improvements, x86 x2APIC support, a fb driver for VIA UniChrome devices, Mitac Mio A701 ARM-based smartphone support, some new drivers, improved device support, and many other small improvements and fixes.
