then look for line 103

100 key ddns_key
101 {
102 algorithm hmac-md5;
103 secret "use /usr/sbin/dns-keygen to generate TSIG keys";
104 };
105 view "external"
106 {

then issue below command in the terminal to get a key
# /usr/sbin/dns-keygen
MYuDOCEckswLfQdVgMjwybFZcB69Jwjv9KMJw7AumSD54dJhdHre2dQYYYmz

Then replace above line(103) as mentioned in the below sample example:

100 key ddns_key
101 {
102 algorithm hmac-md5;
103 secret "MYuDOCEckswLfQdVgMjwybFZcB69Jwjv9KMJw7AumSD54dJhdHre2dQYYYmz";
104 };
105 view "external"
106 {

Then give a below mentioned command

[root@phpmyadmin ram]# /etc/init.d/named restart
Stopping named: [ OK ]
Starting named: [ OK ]
[root@phpmyadmin ram]#

That's it and Enjoys Guys

checking for kde-config... not found

Error message that i received when i was trying to install Umbrello error is as follow

checking for kde-config... not found
configure: error: The important program kde-config was not found!
Please check whether you installed KDE correctly.

Solution : check whether all kde packages are installed properlly . if everything is done
and still you get this error message .
Then please go to the directory /usr/bin and check for kde-config if it their then you can
install any of your application and if in case if some higher version is their like kde4-config
then do "cp kde4-config kde-config " then try this it should work .

Thanks.

In hope solution you liked it.

PHP Deployment in Fedora Core 7,8,9

yum install php php-devel php-gd php-imap php-ldap php-mysql php-odbc php-pear php-xml php-xmlrpc curl curl-devel perl-libwww-perl ImageMagick libxml2 libxml2-devel

phpmyadmin: cannot load mcrypt extension

How-To create a MySQL database and set privileges to a user

On default settings, mysql root user do not need a password to authenticate from localhost. In this case, user can login as root on your mysql server using:
$ mysql -u root
If a password is required, use the extra switch -p:
$ mysql -u root -p
Enter password:
Now that you are logged in, we will create a database:
mysql> create database ramdb;
Query OK, 1 row affected (0.00 sec)
We allow user ramuser to connect to the server from localhost using the password rampasswd:
mysql> grant usage on *.* to ramuser@localhost identified by 'passwd';
Query OK, 0 rows affected (0.00 sec)
And finally we grant all privileges on the ramdb database to this user:
mysql> grant all privileges on ramdb.* to ramuser@localhost ;
Query OK, 0 rows affected (0.00 sec)
And that's it. You can now check that you can connect to the MySQL server using this command:
$ mysql -u ramuser -p'passwd' ramdb
Your MySQL connection id is 12
Server version: 5.0.38-Ubuntu_0ubuntu1-log Ubuntu 7.04 distribution
