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.

In Linux-2.6.33, the function ipv6_add_addr() in addrconf.c sets ifa->flags to IFA_F_TENTATIVE. This is set to IFA_F_PERMANENT only after "Duplicate Address Detection" procedure is completed successfully. In the above listed program, bind() is being called immediately after assigning the IP address. Hence the inet6_bind() in af_inet6.c fails since ifa->flags is still set to IFA_F_TENTATIVE. This issue can probably be resolved by using the IFA_F_NODAD flag (which disables "Duplicate address detection" procedure). So the question is, how do I pass this flag from userspace to the kernel?
