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'm running FC3 and just did an update now my eth0 will not come up. I can cd /proc but not into /proc/net I get "permission denied" even as root. I tested with knopix and all is fine on the hardware. Has any one else seen this? the only other change was the install of VMware, but things kept working after the install of VMware things broke RIGHT after my last update with apt-get. and for the life of me I do not remember all that was updated.
The OS has no clue even what /proc/net is the formating on this is a little messed up just imagend more spaces here and there but insted of
"dr-xr-rr-x" I get "d---------"
and insted of "5 root root 0 may 6 06:51" I get "? ? ? ? ?"
My Toshiba laptop has been running FC3 for sometime now. When fc4 test came out, I upgraded to it successfully. Everyother day I would run yum -y update.
This command would update my fc4 with the latest packages. Things were fine untill two days ago I did the same then rebooted my machine to enable the latest kernel to reboot.
Now my laptop reboots fine, although the driverloaderbuilder complains about not finding the source code for the kernel to build the system modules!
Then I type my user id and password at the prompt, after the boot is completed. Linux logs me in and tries to create a shell for me, but then it logs me out with /bin/bash no permission.
I checked the permissions on /bin/bash. They are 0755. I checked my ownership of /home/userdir it did not show userdir.userdir it showed 500.500! I am sure that was not the case before.
What puzzles me is that I can not even login as root, although the /root directory is owned by root.
I am using redhat8 admin disk to login. When I tried to reset the ownership of my home/userdir of course it did not find me in the passwd file.
What can I do now to recover my machine? Was I hacked or was it just a silly update mistake?
