Broadcom Wireless Setup for Ubuntu 8.04

I used the following steps to enable my Broadcom Wireless

Step 1 (run in terminal)

echo 'blacklist bcm43xx' | sudo tee -a /etc/modprobe.d/blacklist
sudo apt-get install ndiswrapper-utils-1.9
mkdir ~/bcm43xx; cd ~/bcm43xx

For Step 2, You can check your Broadcom wireless version with this command in terminal : "lspci | grep Broadcom\ Corporation",if your wireless device is different from BCM4312 (rev 02), please refer to the following link for this step and you can continue again with step 3 onwards:

Step 2 (run in terminal)

sudo apt-get install cabextract
wget ftp://ftp.compaq.com/pub/softpaq/sp3...00/sp34152.exe
cabextract sp34152.exe

Step 3 (run in terminal)

sudo ndiswrapper -i bcmwl5.inf
ndiswrapper -l
sudo depmod -a
sudo modprobe ndiswrapper
sudo cp /etc/network/interfaces /etc/network/interfaces.orig
echo -e 'auto lo\niface lo inet loopback\n' | sudo tee /etc/network/interfaces
sudo ndiswrapper -m
echo 'ndiswrapper' | sudo tee -a /etc/modules
echo 'ENABLED=0' | sudo tee -a /etc/default/wpasupplicant

Step 4 (run in terminal)

sudo aptitude remove b43-fwcutter

Step 5 (run in terminal)

sudo gedit /etc/init.d/wirelessfix.sh

Step 6

Paste the followings in the opened file(wirelessfix.sh)and make sure you save it before continuing Step 7

#!/bin/bash
modprobe -r b44
modprobe -r b43
modprobe -r b43legacy
modprobe -r ssb
modprobe -r ndiswrapper
modprobe ndiswrapper
modprobe b44

Step 7 (run in terminal)

Run this :

cd /etc/init.d/ && sudo chmod 755 wirelessfix.sh

Step 8 (run in terminal)

finally run this:

sudo update-rc.d wirelessfix.sh defaults

Step 9

Restart your machine and enjoy the freedom from those wires....

phpMyAdmin: No activity within 1440 seconds; please log in again

phpMyAdmin’s “No activity within 1440 seconds; please log in again” message is slowly but definitely driving you crazy. How to remain sane?

Solution

Increase the time limit. Open the file /etc/phpmyadmin/config.inc.php and add the following line to its end:


$cfg['LoginCookieValidity'] = 60 * 60 * 8; // in seconds (8 hours)
Here I set 8 hours, but you can change that.

When you log in again in phpMyAdmin, this new value will be taken into account.

Please make sure that gc_maxlifetime in php.ini is set greater than the given value

Time Difference

We can find the days, hours, minutes, year difference


SELECT TIMESTAMPDIFF( HOUR , '2011-02-10 11:14:36' , NOW( )) ;

Also this,

SELECT TIMEDIFF( NOW( ) , '2011-02-10 14:06:36' ) ;



There is also a way to add values to date using

SELECT TIMESTAMPADD( HOUR , '2011-02-10 11:14:36' , NOW( )) ;

Fix : Could not reliably determine the server’s fully qualified domain name, using 127.0.1.1 for ServerName

Many of us face the same following error we restarting the Apache server on Ubuntu.


sudo /etc/init.d/apache2 restart
* Restarting web server apache2 apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName
... waiting apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName


To fix that problem, you need to edit the httpd.conf file. Open the terminal and type

sudo gedit /etc/apache2/httpd.conf

By default httpd.conf file will be blank. Now, simply add the following line to the file

ServerName localhost

Save the file and exit from gEdit.

Finally restart the server.

sudo /etc/init.d/apache2 restart
