Solution: here we have an implicit rule and an explicit rule in the same line, so we are going to split that rules.

# Modules

#      $(Q)$(MAKE) KBUILD_MODULES=$(if $(CONFIG_MODULES),1) \

HowTo Clean and Re-build Squid cache

First, check your squid.conf file and locate the location of your cache directory, you should have a line starting with "cache_dir"

1. Shutdown your squid server: squid -k shutdown
2. Remove the cache directory: rm -r /squid/cache/*
3. Re-Create the squid cache directory: squid -z
4. Start the squid cache server

IcePHP-3.2.1 Gentoo ebuild

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. As its name indicates, the middleware may be used for internet applications without the need to use the HTTP protocol and is capable of traversing firewalls, unlike most other middleware.

PostgreSQL: ERROR: new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII)

Error:

sqlalchemy.exc.DataError: (psycopg2.DataError) new encoding (UTF8) is incompatible with the encoding of the template database (SQL_ASCII)
HINT: Use the same encoding as in the template database, or use template0 as template.

[SQL: CREATE DATABASE hydra ENCODING 'utf8' TEMPLATE template1]
(Background on this error at: http://sqlalche.me/e/9h9h)

Solution:
First, we need to drop template1. Templates can’t be dropped, so we first modify it so it's an ordinary database:

UPDATE pg_database SET datistemplate = FALSE WHERE datname = 'template1';

Now we can drop it:

DROP DATABASE template1;

Now its time to create a database from template0, with a new default encoding:

CREATE DATABASE template1 WITH TEMPLATE = template0 ENCODING = 'UNICODE';

Now modify template1 so it’s actually a template:

UPDATE pg_database SET datistemplate = TRUE WHERE datname = 'template1';

Now switch to template1 and VACUUM FREEZE the template:

\c template1

VACUUM FREEZE;

The problem should be resolved now.

GRSecurity + Java = Killed + Headup = Running App

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

1. The kernel kills applications.
2. Some applications can not start.
3. We can't compile applications.
4. And many others.....

This problem depends on the security level configured in the kernel. We need to configure and tell the system that some blocked applications are reliable and trusted, this is because some legitimate applications will attempt to generate code at run time which is executed out of memory. PaX does not allow this and will promptly kill the offending application.

The most notable of these applications are XFree/Xorg, mplayer, and multimedia tools based on xine-lib and Java virtual machine.

The problem is the mprotect flag, because it is enabled.

Name

mprotect - control allowable accesses to a region of memory

Synopsis
#include 
int mprotect(const void *addr, size_t len, int prot);

Description
The function mprotect() specifies the desired protection for the memory page(s) containing part or all of the interval [addr,addr+len-1]. If an access is disallowed by the protection given it, the program receives a SIGSEGV. 

The goal of MPROTECT is to help prevent the introduction of new executable code into the task’s address space. This is accomplished by restricting the mmap() and mprotect() interfaces.

The restrictions prevent:
     - Creating executable anonymous mappings.
     - Creating executable/writable file mappings.
     - Making an executable/read-only file mapping writable except for performing relocations on an ET_DYN ELF file (non-PIC shared library).
     - Making a non-executable mapping executable.

So we need to disable it.

Timezone configuration guide for Mexico

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:

pluton ~ # cat /etc/conf.d/hwclock
TIMEZONE="Mexico/General"

clock="UTC"
clock_systohc="YES"
clock_hctosys="YES"
clock_args=""

Restart the service:

pluton ~ # /etc/init.d/hwclock restart
 * WARNING: you are stopping a boot service
 * Caching service dependencies ...                                                                                                                                                                 [ ok ]

Check 32 and 64 bits compatibility on 64bits Kernel

First, we need to check if we have a 64Bits Kernel running.

Some Linux distros use a release file to save the version, codename, and other information

alvaro@linux-a77o:~> cat /etc/SuSE-release
openSUSE 11.4 (x86_64)
VERSION = 11.4
CODENAME = Celadon

Or check the system information using uname

alvaro@linux-a77o:~> uname -a
Linux linux-a77o 2.6.37.1-1.2-desktop #1 SMP PREEMPT 2011-02-21 10:34:10 +0100 x86_64 x86_64 x86_64 GNU/Linux

Or something a little more standard...

alvaro@linux-a77o:~> perl -MConfig -e 'print $Config{longsize}*8 . "\n";'
64

With this code, we are going to be testing system libraries and support.

alvaro@linux-a77o:~> cat test-bits.c
#include 

int main()
{
	long z; 
	printf("Long int size is %i bytes long!\n", sizeof(z)); 
	return 0;
}

Without the 32bits support, we can only compile the 64bits binary.
The 32bits compilation will show some fatal errors, like this one:

alvaro@linux-a77o:~> gcc -m64 -o output64 test-bits.c 
alvaro@linux-a77o:~> gcc -m32 -o output32 test-bits.c 
In file included from /usr/include/features.h:371:0,
                 from /usr/include/stdio.h:28,
                 from test-bits.c:1:
/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory
compilation terminated.

In this example I used OpenSuse, so these are the steps to solve the problem in this version:

• Software Management ->
• View ->
• Patterns ->
• Search "Base Technologies" and then "32-bit runtime Library" ->
• Activate some or all the checkboxes (you maybe need the CD, DVD or ISO image).

After installing or configuring the 32bits library support, we successfully compile and execute the binaries.

alvaro@linux-a77o:~> source /etc/profile
alvaro@linux-a77o:~> rm output*
alvaro@linux-a77o:~> gcc -m32 -o output32 test-bits.c 
alvaro@linux-a77o:~> gcc -m64 -o output64 test-bits.c 
alvaro@linux-a77o:~> ./output32 
Long int size is 4 bytes long!
alvaro@linux-a77o:~> ./output64 
Long int size is 8 bytes long!

Install IcePHP using Ice-3.4.1

First, you need to install the Ice libs.

To compile the IcePHP library we need to go to the php directory.

zeus ~ # cd Ice-3.4.1/php/

In order to set the path of php libraries, we need to set it in the Make.rules.php file, but first, we must know where the libraries are.

zeus php ~ # locate php.h
/usr/lib/php5/include/php/main/php.h
/usr/share/doc/freetds-0.64/userguide/php.htm

zeus php ~ # vi config/Make.rules.php
PHP_HOME                ?= /usr/lib/php5

We have all configured, so we just need to compile the library.

Is just because your ICE_HOME environment variable is missing, you can set this variable in the global profile or just for this build.

zeus php # export ICE_HOME=/usr/ && make

And our Dynamically Linked "Shared Object" library it will be in the lib directory.

zeus php ~ # ll lib/IcePHP.so
-rwxr-xr-x 1 root root 3171151 Nov  1 23:11 lib/IcePHP.so

Now you need to copy this library in some directory and append this directory in the extensions section of the php.ini file.

zeus php ~ # cp lib/IcePHP.so /etc/php/apache2-php5/ext
zeus php ~ # vi /etc/php/apache2-php5/php.ini
extension_dir = /etc/php/apache2-php5/ext
extension = IcePHP.so

Also in the lib directory, we will find all the PHP-ICE library files that our web apps need.

zeus php ~ # ll lib/

Now we need to copy these libraries in the PHP shared folder and append the new path of Ice libraries

zeus php ~ # cp -rfv lib/ /usr/share/php/Ice-3.4.1
`Ice-3.4.1/php/lib/' -> `/usr/share/php/Ice-3.4.1'

...

zeus php ~ # vi /etc/php/apache2-php5/php.ini
include_path = ".:/usr/share/php5:/usr/share/php:/usr/share/php/Ice-3.4.1"

Finally, do not forget to restart the apache web server.

zeus php ~ # /etc/init.d/apache2 restart
 * Stopping apache2 ...                                                                                   [ ok ]

If you got an error like this:

DotDotPwn-2.1 Gentoo ebuild

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, and 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.

... our vmware-server cannot start, to solve this problem we need to work with some PaX utils and applications, such as paxctl and chpax, in order to change the rules of security but only with some applications.

The next script will change the security policy rules of the vmware-server-2.0.2.
First the config and opts file.

vm-win ~ # cat /etc/conf.d/grsecurity

CHPAX_OPTIONS="-rsm"

PAXCTL_CMD="/sbin/paxctl"
PAXCTL_OPTIONS="-pemrxs"

Then the init script.

I know!!!!.... This is an ugly script, but it worked at a "Hardened Gentoo [server] " security level.
