How can I recover the password to my linux server I know my username I just need password?

Q. How can I recover the password to my linux server I know my username I just need password? I have a Linux server and i dont know how to accsess it any help would be appreciated.

A. Passwords are hashed in a one-way direction; you can't retrieve the old password. Most Linux distros will allow you to boot in a single-user mode, meaning you are given a root shell. From here, you can change the password with this command:

passwd username

substituting in the correct user name. You will be prompted to enter a new password twice. After that, just reboot.

What is the best documentation for Linux servers?
Q. Linux server with better documentation to enter the world of Linux servers.

A. Linux server? What server? Every Linux application, server or not, includes the author's documentation. There is a Linux command that specifically opens those files. It's called "man" (short for manual) like "man apache" (Apache is the worldwide leading web server to date). If you search the internet for more documentation, chances are you will be brought to a page that more or less replicates the 'man' page. There are other sites that document personal notes about installation which may or may not be useful to you and there are books that cater to specific and broad server installation procedures which more or less go back to the man page.

How do you Reboot a Macbook to use a linux server?
Q. I need to install a linux server on my macbook, but I am having trouble rebooting it and for it to recognize the server. Can someone please help me out?

A. The EFI on mac's is a little tricky to work with. A lot of good info availible on the reEFIt site. A protective MBR is probably the easiest setup to work with.
