@ Unspawn
I dont use any additional 3rd party applications at all other than just Java application for chat.
@ Neo
Yes, I come here to look for easy way for quick response.
I have got your answer, you suggest me to use that tripwire to secure my /tmp. But, that's just a long term action, I need "short quick response actions" for this. Anything like blocking port 6667 & 7000 effectively, prevent IRC script from running, etc.
Talking about the web vulnerabilities:
# If it's about SQL injection attack, when someone got the credential login like Cpanel/FTP or Admin login, what can he do other than just playing around with C99/R57 shell??
# If he playing with C99/R57 shell, how can he runs exploit coded in C, where GCC is disabled for user?
# If he runs exploit not coded in C, but coded in Perl, then successfully rooting my server, then I think this is a big security hole in Centos 5!
# If he got MySQL login from particular user, how can he write files in /root, where particular user (MySQL) only has USAGE privileges? If it has nothing to do with MySQL privileges, then how he wrote files in /root other than exploited the server?
# Result from RKHunter & ClamAV shows that /dev and /tmp are the only directories which are suspicious. I have tried to look for any information on the net but no luck.
I think I have explain all things what I know about the main web server vulnerabilities. So what else to check other than that?
If there's no satisfy answers from ppl in this forum, I think this will be my last post. I'm tired. I think I'm just asking for simple question, but none answered my question at all. Wonder if in this big UNIX forum, no one ever dealt with IRC botnet. Huft..
Thanks all.

mysql_fix_privilege_tables
MYSQL_FIX_PRIVILE(1) MySQL Database System MYSQL_FIX_PRIVILE(1)
NAME
mysql_fix_privilege_tables - upgrade MySQL system tables
SYNOPSIS
mysql_fix_privilege_tables --password=root_password
DESCRIPTION
Note
In MySQL 5.1.7, mysql_fix_privilege_tables was superseded by mysql_upgrade, which should be used instead. See mysql_upgrade(1).
Some releases of MySQL introduce changes to the structure of the system tables in the mysql database to add new privileges or support new
features. When you update to a new version of MySQL, you should update your system tables as well to make sure that their structure is up
to date. Otherwise, there might be capabilities that you cannot take advantage of.
mysql_fix_privilege_tables is an older script that previously was used to uprade the system tables in the mysql database after a MySQL
upgrade.
Before running mysql_fix_privilege_tables, make a backup of your mysql database.
On Unix or Unix-like systems, update the system tables by running the mysql_fix_privilege_tables script:
shell> mysql_fix_privilege_tables
You must run this script while the server is running. It attempts to connect to the server running on the local host as root. If your root
account requires a password, indicate the password on the command line like this:
shell> mysql_fix_privilege_tables --password=root_password
The mysql_fix_privilege_tables script performs any actions necessary to convert your system tables to the current format. You might see
some Duplicate column name warnings as it runs; you can ignore them.
After running the script, stop the server and restart it so that any changes made to the system tables take effect.
On Windows systems, MySQL distributions include a mysql_fix_privilege_tables.sql SQL script that you can run using the mysql client. For
example, if your MySQL installation is located at C:Program FilesMySQLMySQL Server 5.1, the commands look like this:
C:> cd "C:Program FilesMySQLMySQL Server 5.1"
C:> binmysql -u root -p mysql
mysql> SOURCE share/mysql_fix_privilege_tables.sql
Note
Prior to version 5.1.17, the mysql_fix_privilege_tables.sql script is found in the scripts directory.
The mysql command will prompt you for the root password; enter it when prompted.
If your installation is located in some other directory, adjust the path names appropriately.
As with the Unix procedure, you might see some Duplicate column name warnings as mysql processes the statements in the
mysql_fix_privilege_tables.sql script; you can ignore them.
After running the script, stop the server and restart it.
