Settings Wireless Region Linux – Channel 13 Backtrack 4

One of the most recent problems I stumbled upon while running Backtrack, or any other linux distro for that matter is setting the region on a wireless card.  The typical procedure is :

1
iwconfig wlan0 channel 13

And commonly you will get

1
2
3
error for wireless regquest ''set frequency''
(8b04)
set failed on device wlan0 ; invalid arugment

There is an easy fix for this that will allow you to change the region mode your wireless adapter is in.

1
iw reg set FR
1
iw reg set US

Create multiple email accounts Plesk 8

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:

#/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
