ThinkPad x201 Ubuntu 10.04 Lucid Lynx Wireless

admin — Mon, 14 Jun 2010 11:19:26 +0000

The ThinkPad x201 is a great platform for Ubuntu 10.04. The default installation contains an outdated version of the Thinkpad BGN wireless drivers. After first boot you can see networks(not all available), and connect to some – but in general this will give you difficulties. The recommendation is to first update your installation via-Ethernet to automatically download the patch. Upon restart, you will have a fully functional Ubuntu installation.

This is where and how it was solved:

Add jail shelled FTP/SSH user on CentOS / Plesk

admin — Thu, 22 Apr 2010 13:47:32 +0000

The process of adding a new FTP user with SSH access to a Plesk / CentOS server is more difficult than it needs to be. Plesk will only allow you to add WebUsers to your domains which have FTP accounts, not full SSH accounts. Here is the quick and dirty. We want our new user to be in chroot jail and to inherit the same permissions as another user on the system. The user will be restricted to the top level directory you define (for example httpdocs in this case).

1	cat /etc/passwd/ \| grep 'anyusername'

This will return:

anyusername:x:10009:2524::/var/www/vhosts/anydomain.com:/bin/bash

The first set of numbers after “:x:” is the UID or User Identifier. We will use this in the next command to copy the same permissions.

1	useradd -u 10009 -o -d /var/www/vhosts/anydomain.com/httpdocs/ -g psaserv -s /usr/local/psa/bin/chrootsh newusername

Replace “anydomain.com” with your domain, and “newusername” with the new user you would like to add.

1	passwd newusername

Gives the user a password.

1	usermod -s /bin/bash newusername

Boom! Done.

2. Plug in active internet connection the Wired ethernet

3. Run update-manager

4. Restart after Kernel update

5. Now with internet still plugged in, goto System>Administration>Hardware Drivers

Create multiple email accounts Plesk 8

admin — Wed, 03 Feb 2010 10:06:33 +0000

After much hunting around and reading through the Plesk Administrator Guide I finally found an easy way for creating multiple e-mail accounts in batch! This is not a MySQL hook or database related, but stems from the logic of wanting to create multiple accounts at once.

To create an e-mail account in Plesk, first login to your server via SSH.

Execute the following:

/usr/local/psa/bin/mail --create new@yourdomain.com -passwd newpassword-cp-access false

If you want to run a batch, create a script:

1
2
3
4
5
6
7
8
9

#/bin/bash

/usr/local/psa/bin/mail --create new@yourdomain.com -passwd newpassword-cp-access false

/usr/local/psa/bin/mail --create new@yourdomain.com -passwd newpassword-cp-access false

/usr/local/psa/bin/mail --create new@yourdomain.com -passwd newpassword-cp-access false

/usr/local/psa/bin/mail --create new@yourdomain.com -passwd newpassword-cp-access false

Reset “lost” Administrator Password Mac OS X

admin — Mon, 30 Nov 2009 15:53:24 +0000

Lost your administrator password? Working with a client who has lost their administrator password and need to install applications and updates? Here is a very simple workaround to resetting the password on any account in OS X.

So what do we do?

Basically start up your Mac in single user mode, deleting the local profile cache for the creation of a new user. Upon restart, you will be prompted to setup a new administrator account. This process of creating this account is the same as after a fresh install. Once you have logged in under the new account, open System Preferences>Accounts and change the password of your original account. No data is lost, and nothing is deleted. Logout/Login with your new password and then delete the temporary admin account.

Presto – Password recovered.

1. Reboot in Single User Mode – hold Apple Key(command)-S after you hear the chime

2. Run the following:

1
2
3

mount -uw /
rm /var/db/.AppleSetupDone
shutdown -h now

**Note**
In terms of security, this is why restriction of physical access to a machine is critical. Passwords are not safe, and are not to be conceived as “safe”. Strong passwords are irrelevant if you do not limit physical access to machines. Play safe.

Grub2 – A beginners guide

admin — Tue, 24 Nov 2009 11:22:45 +0000

Take a look at this post over at Ubuntu forums for a very comprehensive, yet easy to understand guide to Grub2. Noteworthy mentions are as follows:

“At first boot, there will not be much difference in what the user sees on the boot menu. The one exception is a clean install of Ubuntu 9.10 with no other installed operating system. In this case, GRUB 2 will boot directly to the login prompt or Desktop without displaying a menu. Other major differences:

No ”/boot/grub/menu.lst”. It has been replaced by ”/boot/grub/grub.cfg”.
Hold down SHIFT to display the hidden menu during boot (formerly ESC is GRUB legacy).
There is no “find /boot/grub/stage1″ at the grub prompt. Stage 1.5 has also been eliminated.
The main menu file, ”/boot/grub/grub.cfg” is not meant to be edited, even by ‘root’.
”grub.cfg” is overwritten anytime there is a update, a kernel is added/removed or the user runs `update-grub` *
The user can use a custom file, ”/etc/grub.d/40_custom”, in which the user can place his own entries. This file will ”not” be overwritten.
The primary configuration file for changing menu display settings is ”/etc/default/grub”.
There are multiple files for configuring the the menu – ”/etc/default/grub” mentioned above, and all the files in ”/etc/grub.d/” folder.
Other operating systems, such as Windows, should automatically be recognized and added to the menu.
No changes made in the configuration files will take effect until the `update-grub` command is also run.”

Ubuntu Karmic 9.10 and Gigabyte GA-EP45-UD3P – Black screen

admin — Tue, 24 Nov 2009 11:04:46 +0000

After any install of Karmic, 9.10 the new GRUB 2 bootloader will not start the generic kernel. On first reboot after a fresh install, when you select the standard boot image you are left with a black screen, and possibly a blinking cursor in the upper left hand corner. To boot anything functional I was forced to start in rescue mode, resume normal boot, login as my user, then run startx to start GNOME. What a disaster! Simple fix? You got it!

It’s time to edit Grub2, a daunty little beast that is not to be mistaken for Grub.

1. Open the grub config

1	sudo gedit /etc/default/grub

2. A note : grub.cfg cannot be modified without changing the file permissions first. Do not modify /boot/grub/grub.cfg Simply put, every time you run update-grub this file is re-generated. Changes here can be dangerous.

3. Find the following, or similar depending on your kernel

1	linux /boot/vmlinuz-2.6.31-14-generic root=UUID=94db3b6d-1959-49d3-8565-6e3e28acdc64 ro quiet splash

4. Remove “quiet splash”

1	linux /boot/vmlinuz-2.6.31-14-generic root=UUID=94db3b6d-1959-49d3-8565-6e3e28acdc64 ro

5. Run

1	sudo update-grub

6. Reboot

Cannot connect to MySQL: Client does not support authentication protocol requested by server

admin — Tue, 24 Nov 2009 10:21:23 +0000

I ran into a problem on a client site running cPanel. One our our web apps was spitting out the following error:

1 2	Script Error Cannot connect to MySQL: Client does not support authentication protocol requested by server; consider upgrading MySQL client

A quick Google search returned the fix : http://geekswithblogs.net/TimH/archive/2005/10/31/58591.aspx

From inside MYSQL, Run the following on the affected DB:

1	SET PASSWORD FOR user@localhost = OLD_PASSWORD('replacemepasswd');
