How to uninstall isc-dhcp-server

Kamis, 05 Maret 2015

To uninstall isc-dhcp-server just follow these instructions.
 Uninstall just isc-dhcp-server: sudo apt-get remove isc-dhcp-server 
This will remove just the isc-dhcp-server package itself.

 Uninstall isc-dhcp-server and it's dependencies: sudo apt-get remove --auto-remove isc-dhcp-server This will remove the isc-dhcp-server package and any other dependant packages which are no longer needed. 

Purging your config/data too If you also want to delete your local/config files for isc-dhcp-server then this will work. 
Caution! Purged config/data can not be restored by reinstalling the package.
sudo apt-get purge isc-dhcp-server 
Or similarly, like this isc-dhcp-server
sudo apt-get purge --auto-remove isc-dhcp-server

Configure a Squid proxy server through Webmin n Your Squid cache directory /var/spool/squid3 has not been initialized

Sabtu, 03 Januari 2015

By Jack Wallen in SMB Technologist Setting up Squid The first thing you will see is the error "Your Squid cache directory /var/spool/squid3 has not been initialized. This must be done before Squid can be run." In order to initialize this, click the Initialize Cache button (with either an existing user, or you can create a new user/group "proxy"). At this point you will see the "Stopping Squid" warning. Once the system has been initialized, you will be prompted with the Return To Squid Index link. If you continue seeing this error, here's what you need to do: Open a terminal window. Open the file /etc/squid3/squid.conf. Search for the line #cache_dir ufs /var/spool/squid3 100 16 256 (around line 2245). Remove the "#" character. Save the file. Go back to Webmin and click the Initialize Cache button again. Your plan for using the proxy will dictate how you configure it. Regardless of how you use it, you will want to define the ports used by the proxy first. By default, Squid uses 3128. You can stick with the default, or if you need to go with a non-standard port.

MySQL 5.0 Reference Manual: How to Reset the Root Password

How to reset your password in Ubuntu

There are many reasons you might want to reset a password:
Someone gave you a computer with Ubuntu installed on it but not the password for the user account.
You just installed Ubuntu and forgot what password you selected during the installation process.
You have too many passwords in your life and can't keep track of them all.
Well, this tutorial will help you reset your Ubuntu user account password, regardless of what reason you have for resetting it.
First, you have to reboot into recovery mode.
If you have a single-boot (Ubuntu is the only operating system on your computer), to get the boot menu to show, you have to hold down the Shift key during bootup.
If you have a dual-boot (Ubuntu is installed next to Windows, another Linux operating system, or Mac OS X; and you choose at boot time which operating system to boot into), the boot menu should appear without the need to hold down the Shift key.

From the boot menu, select recovery mode, which is usually the second boot option.

After you select recovery mode and wait for all the boot-up processes to finish, you'll be presented with a few options. In this case, you want the Drop to root shell prompt option so press the Down arrow to get to that option, and then press Enter to select it.

The root account is the ultimate administrator and can do anything to the Ubuntu installation (including erase it), so please be careful with what commands you enter in the root terminal.

In recent versions of Ubuntu, the filesystem is mounted as read-only, so you need to enter the follow command to get it to remount as read-write, which will allow you to make changes:

mount -o rw,remount /

If you have forgotten your username as well, type

ls /home
That's a lowercase L, by the way, not a capital i, in ls. You should then see a list of the users on your Ubuntu installation. In this case, I'm going to reset Susan Brownmiller's password.
To reset the password, type

passwd username
where username is the username you want to reset. In this case, I want to reset Susan's password, so I type
passwd susan
You'll then be prompted for a new password. When you type the password you will get no visual response acknowledging your typing. Your password is still being accepted. Just type the password and hit Enter when you're done. You'll be prompted to retype the password. Do so and hit Enter again.

Now the password should be reset. Type

to return to the recovery menu.
After you get back to the recovery menu, select resume normal boot, and use Ubuntu as you normally would—only this time, you actually know the password!

Some people get freaked out about having recovery mode logging you in as root.

Jalankan perintah :
