2. Edit suphp.conf

vi /etc/suphp.conf

[global]
logfile=/var/log/httpd/suphp_log
loglevel=info
webserver_user=apache
docroot=/
env_path=/bin:/usr/bin
umask=0022
min_uid=500
min_gid=48

; Security options
allow_file_group_writeable=false
allow_file_others_writeable=false
allow_directory_group_writeable=false
allow_directory_others_writeable=false

;Check wheter script is within DOCUMENT_ROOT
check_vhost_docroot=true

;Send minor error messages to browser
errors_to_browser=true

[handlers]
;Handler for php-scripts
x-httpd-php=php:/usr/bin/php-cgi

;Handler for CGI-scripts
x-suphp-cgi=execute:!self

3. Disable the original PHP 5 module.

[root@example etc]# mv /etc/httpd/conf.d/php.conf /etc/httpd/conf.d/php.conf.disabled

[root@example etc]# vi /etc/httpd/conf.d/suphp.conf

LoadModule suphp_module modules/mod_suphp.so

suPHP_Engine on

AddHandler x-httpd-php .php
AddHandler x-httpd-php .php .php4 .php3 .phtml

# suPHP_UserGroup apache apache

suPHP_AddHandler x-httpd-php

4. I have the following VirtualHost definition in my apache config file:-

<VirtualHost *:80>
ServerAdmin user@example.com
DocumentRoot /var/www/vhosts/example.com
ServerName www.example.com
suPHP_UserGroup user apache
</VirtualHost>

[root@example etc]# ls -l /var/www/vhosts/

total 4
drwxr-xr-x 2 user apache 4096 2008-06-04 00:18 example.com

[root@example]# ls -l /var/www/vhosts/example.com/
total 4
-rw-r–r– 1 user apache 37 2008-06-04 00:18 index.php

Service httpd restart

Open a browser and try opening the www.example.com site (whatever is your virtualhost).

You should get the following , as a result of successful execution of suphp for your virtualhost.

[root@example ~]# tail -f /var/log/httpd/suphp_log

File Creation Test: (Last Test, for which we undergo all this pain) :-
——————————————————————–
Create a file through php script. It SHOULD get created as user webmaster and group apache (if your setup is successful).

Here is the code you can put in a file, say createfile.php in your documentroot. Note it is a MUST to setup the ownership and permission of your php file as the same owner / group of your document root.

vi /var/www/vhosts/example.com/createfile.php

<?php
$file=”testfile.html”;
$fp=fopen($file,”w”);
# echo “This script is being run as user (ID) : “. fileowner(‘createfile.php’) . “<br>”;
echo “The owner of the script being run : get_current_user : ” . get_current_user() . “<br>”;
echo “The UID of the user: int getmyuid ( void ) : ” . getmyuid() . “<br>”;

if (fwrite($fp,”<h1>Hello</h1>”))
echo “File created.”;
else
echo “File not created !!!”;
fclose($fp);
?>

chown user:apache /var/www/vhosts/example.com/createfile.php

Run this file through browser and you should see a file created as testfile.html in your documentroot . Just for the sake of completeness of this document, the contents of that file would be a word “Hello”.

As you can see from the file list below, the file is successfully created in my documentroot, with correct ownership and permissions.

[root@example etc]# ls -l /var/www/vhosts/example.com/
total 12
-rw-r–r– 1 user apache 247 2008-06-04 11:08 createfile.php
-rw-r–r– 1 user apache  37 2008-06-04 00:18 index.php
-rw-r–r– 1 user apache  14 2008-06-04 11:07 testfile.html

You should get the following , as a result of successful execution of suphp for your this file.

[root@user ~]# tail -f /var/log/httpd/suphp_log

Wubi adds an entry to the Windows boot menu which allows you to run Linux. Ubuntu is installed within a file in the Windows file system (c:ubuntudisksroot.disk), this file is seen by Linux as a real hard disk.

You can download Wubi from here

1.Run wubi, insert a password for the new account, and click “install”. The installation process from this point is fully automatic.

2.The installation files (700MB) will be downloaded and checked, after which you will be asked to reboot. Do so and select Ubuntu at the boot screen.

——————————————-

Wubi also gives you an option of installing Ubuntu from your existing ISO/CD instead of letting Wubi download a new one. If you have an image on CD, physical CDs will be detected automatically.

pre-downloaded ISOs should be placed in the same folder as Wubi.exe. Please note that Wubi 8.04.1 requires the Desktop 8.04.1 CD/ISO, while Wubi 8.04 requires the 8.04 CD/ISO. The DVD and Altrenate CD/ISO will not work.

———————————————-

3.The installation will continue for another 10-15 minutes and the machine will reboot again. Thats it. Now you can select Ubuntu at the boot screen and start using it.

You can see installation steps with screeshot here.

Great na !!!

The all new iPod Touch

91.9 – Radio Mango–

93.5 – S FM — kelkku kelkku kettukondae irikku

94.3 – Club FM — Ton kanakkinu fun

Hear the title song of Club FM..Really super.. Mazhayathum veylathum…..

1.Insert the EvDO device into USB port                                  

2. Login as root

3. Check whether the device is getting detected on your system or not. For that use the command:

tail -f /var/log/messages

Now you should see something like:

———————————————–

usb 4-1: configuration #1 chosen from 1 choice
usbserial_generic 4-1:1.0: generic converter detected
usb 4-1: generic converter now attached to ttyUSB0

————————————————-

If not, then you have to do the following steps:

4. If you are using Ubuntu 7.04 and 7.10, then do the following also:

———————————————————

vi /etc/init.d/mountdevsubfs.sh

———————————————————

5. find the function do_start () and edit it, such that it shud look like :

——————————————————-

#
# Magic to make /proc/bus/usb work
#
mkdir -p /dev/bus/usb/.usbfs
domount usbfs “” /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount –rbind /dev/bus/usb /proc/bus/usb

——————————————————–

The above change creates a file called /proc/bus/usb/.usbfs/devices which is missing in the new Ubuntu releases.

6. Now execute the following command:

———————————————-

etc/init.d/mountdevsubfs.sh restart

———————————————–

7. Now, your system can identify the new USB device which you have inserted and you can confirm this by running lsusb command.

———————————————–

# lsusb
Bus 005 Device 004: ID 046d:08c6 Logitech, Inc.
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 027: ID 05c6:6000 Qualcomm, Inc.
Bus 004 Device 001: ID 0000:0000

———————————————–

Here Qualcomm will be the EVDO device.
8. Now insert the driver module into your kernel. Run this at the console to activate the module based on the vendor id and product id. Vendor ID and product ID can be determined from the lsusb command. [ Add 0x as prefix to convert into hexa decimal]

————————————————

# modprobe usbserial vendor=0x05c6 product=0×6000

———————————————

9. Now create the dialup profile. Its can be created with “wvdialconf” command.

10. Open the /etc/wvdial.conf file and edit it according to your need. Give your phone number, username and password.

—————————————————-

# cat /etc/wvdial.conf

[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
; Phone = <Target Phone Number>
ISDN = 0
; Username = <Your Login Name>
Init1 = ATZ
; Password = <Your Password>
Modem = /dev/ttyUSB0
Baud = 460800

Stupid Mode = 1

——————————————-

11. Now give “wvdial” command to connect. To disconnect, press ctrl + c.

12. Surf web & enjooaaay.
