The Internet Communications Engine, or Ice, is an object-oriented middleware that provides object-oriented Remote Procedure Call, grid computing and Publish/subscribe functionality developed by ZeroC and dual-licensed under the GNU GPL and a proprietary license. It supports C++, Java, .NET-languages (such as C# or Visual Basic), Objective-C, Python, PHP and Ruby on most major operating systems such as Linux, Solaris, Windows and Mac OS X. A light variant of ICE runtime, called Ice-e, may run inside mobile phones.

DotDotPwn - The Directory Traversal Fuzzer.
It's a very flexible intelligent fuzzer to discover traversal directory vulnerabilities in software such as Web/FTP/TFTP servers, Web platforms such as CMSs, ERPs, Blogs, etc. Also, it has a protocol-independent module to send the desired payload to the host and port specified. On the other hand, it also could be used in a scripting way using the STDOUT module. It's written in perl programming language and can be run either under *NIX or Windows platforms.

When we work with hardened kernels and tools like grsecurity and PaX, we faced to problems like:

This guide is to learn how to set correctly the timezone in a Gentoo Linux and Mexico/General timezone.

First copy or link the proper zone to localtime:

pluton ~ # ln -sf /usr/share/zoneinfo/Mexico/General /etc/localtime
pluton ~ # ls -l /etc/localtime
lrwxrwxrwx 1 root root 23 Jun  6 18:13 /etc/localtime -> /usr/share/zoneinfo/GMT

Now specify your timezone:

Jun 10 2011

First you need to install the Ice libs.

zeus ~ # emerge Ice -av
These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] dev-libs/Ice-3.4.1  USE="ncurses python -debug -doc -examples -mono -ruby -test" RUBY_TARGETS="ruby18" 0 kB

Total: 1 package (1 reinstall), Size of downloads: 0 kB

Would you like to merge these packages? [Yes/No] 

And then copy the compressed file in a safe and different place, then go there and expand the file.
