Forgotten or Lost Linux Root Password

It’s inevitable that at one time, or another, a Linux sys admin will forget or lose a root password for a system they manage or that they’ll inherit a server to which the root passwords are unavailable for.

Thankfully, a Linux servers root password can be reset in a few simple steps via single-user mode.

To enter single-user mode, reboot your computer. If you use the default boot loader, GRUB, you can enter single user mode by performing the following:

  1. At the boot loader menu, use the arrow keys to highlight the installation you want to edit and type [A] to enter into append mode.
  2. You are presented with a prompt that looks similar to the following:

    grub append>     ro root=LABEL=/

  3. Press the Spacebar once to add a blank space, then add the word single to tell GRUB to boot into single-user Linux mode. The result should look like the following:

    ro root=LABEL=/ single

  4. Press [Enter] and GRUB will boot single-user Linux mode. After it finishes loading, you will be presented with a shell prompt similar to the following: sh-2.05b#

  5. You can now change the root password by typing:

    passwd root

  6. You will be asked to re-type the password for verification. Once you are finished, the password will be changed.

You can then reboot by typing reboot at the prompt; then you can log in to root as you normally would.

Horde Webmail Security

For those using Plesk 9.x, Horde naively allows webmail logins via HTTP (in-secure) or HTTPS (secure). HTTP log-ins are not recommended as username and password information is sent in clear text across the Internet.

In the following example we’ll configure access to http://webmail.yourdomain.com to automatically re-direct to http://webmail.yourdomain.com.

NOTE: These instructions are specific to Plesk’s implementation of Horde but should work on any Horde 3.1.7 installation. Simply locate Horde’s “conf.php” file and adjust the parameters shown below.

[root@youserver /]# nano -w /etc/psa/webmail/horde/horde/conf.php Continue reading “Horde Webmail Security”
