How To Recover the root Password in FreeBSD

The password cannot be recovered. The following procedure will allow you to change the root password.

Do the following:

- when the following boot message appears

Hit [ENTER] to boot immediately, or any other key for command prompt.
Booting [kernel] in 10 seconds...

hit a key, just pick one EXCEPT the ENTER key. You'll get a prompt like:


- type the following commands:

disk1s1a:>unload all
disk1s1a:>load kernel
disk1s1a:>boot -s

The boot process will now start, just wait until it asks you for a shell. Just hit
ENTER and 'sh' will be used as shell.

If you type 'mount' you will see that only your root partition ( / ) is mounted, you will have to mount  'usr' partition as well.

#mount /dev/ad0s1f /usr

Now you have to mount root partition as read-write enabled. Use the following command:

#mount -u /

The root partition should now be mounted read-write. Now you can use 'passwd' program to
change the root password.


That's all, reboot the system and login with the new password.

FreeBSD: How To Upgrade FreeBSD 7 to 8 Stable Release

FreeBSD 7.x allows upgrade of existing installation to FreeBSD 8.0-STABLE. Since this is a major version upgrade, it is recommended that you backup your data, database and configuration files.

This guide will walk a user through updating his source to follow FreeBSD's stable branch.  Please make a full backup of the current system before following this guide.

STEP 1: Syncing the source tree

- cvsup installation and configuration

# cd /usr/ports/net/cvsup-without-gui

# make install clean


# pkg_add -r cvsup-without-gui

Copy the sample supfile for Stable to /usr/local/etc/stable-supfile:

# cp /usr/share/examples/cvsup/stable-supfile /usr/local/etc/

Edit file and set host name which specifies the server host which will supply the file updates to your system.


Set release tag to stable 8:

*default release=cvs tag=RELENG_8

Run cvsup to download the latest stable source:

# cvsup -L 2 /usr/local/etc/stable-supfile

When the cvsup has completed, change to the /usr/src directory

Google acquires Aardvark

When you need an answer to a very specific question, sometimes the information just isn't online in one simple place. For example, let's say you want to know if there's snow on Skyline Boulevard on a given day or the best time of year to plant beans in the Bay Area. You might find weather reports and planting guides on many different sites, but for these kinds of questions, a person with the right expertise can be a lot more useful than a webpage.
