Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I want to use FIPS mode under linux. With openssl-0.9.8o, I typed "./config fipscanisterbuild" and then typed "make". The compile successful.
Then I did a test about fips, below is my test code (main.cpp): #include <iostream>
int main(int argc, char *argv)
std::cout << "OPENSSL_FIPS be defined" << std::endl;
bool bRet = FIPS_mode();
std::cout << "Already in fips mode" << std::endl;
bRet = FIPS_mode_set(1);
std::cout << "FIPS mode set ok" << std::endl;
std::cout << "FIPS mode set failed" << std::endl;
std::cout << "OPENSSL_FIPS not be defined" << std::endl;
And my Makefile is like: XX = g++
CFLAGS = -DOPENSSL_FIPS -I/usr/local/openssl-0.9.8o/include
LDFLAGS = --enable-auto-import -L/usr/local/openssl-0.9.8o/lib -Wl, -Bstatic -lssl -lcrypto -Wl, -Bdynamic -ldl
If the fips mode be setted, the function FIPS_mode_set() will be return 1(true).
I followd the The OpenSSL FIPS User Guide and solved this issue.
Here is the step:
1) add /usr/local/ssl/fips/bin to the environment variable PATH.
2) modify the Makefile to this: XX = g++
