Hello,

I am Ani , and I hail from India. I work as a Freelance Security Vulnerability Analyst and a Linux System Administrator for the past 3 years.

I would like to take this opportunity to put forward a quote for remote system administration of your CPanel installed Linux servers. A few among the many tasks that I perform are:

• Fine tuning of many WHM options
• Installation, configuration and fine tuning of Apache, Exim, FTP, DNS, mySQL on CPanel+Linux servers
• Installation and configuration of PHP and Perl on the server.
• Installation and configuration of extra PHP modules and plugins like IonCube loader, Zend Optimizer etc
• Installation and configuration of additional WHM plugins like WHMXtra, RVSkin Manager and RVSite Builder etc and much more

If your server is a target of DDOS attacks or Spam attacks (inbound and outbound) or Brute force attacks, and don’t know how to tackle them, then I am the guy you are looking for.

These type of attacks mentioned above can easily cause the server load to rise to such an extend that it goes down. In general, a server once online remains online until there occur a network or hardware failure, or till the sys admin restarts it. If you find yourself submitting reboot tickets with the NOC every other day, then maybe you should harden the server. Here are the things I could help you with:

• Installation, configuration and fine tuning of APF, BDF and CSF to prevent DDOS attacks
• Install and configure PRM to check load spikes and kill unwanted processes automatically
• Configure exim to trace spammers on your server
• Create and install shell scripts that automatically delete unwanted mails from the mail queue every hour
• Configure exim to reject mails from IPs that are listed in common RBLs. This could reduce a lot of incoming spam issues on the server
• Install and configure Apache modules like mod_security, mod_throttle, mod_bandwidth and many more (whichever required) to stop Cross scripting attacks and Remote file inclusion attacks
• Fine tuning of FTP and DNS servers

Has your server been hacked recently?? How did he get in? Is the server still vulnerable? Are you receiving abuse reports originating from your server? Well, I may help you with all these:

• Tweak built-in Linux parameters to increase security
• Search for vulnerable files and directories on the server
• Search for common hacker installed shell scripts
• Search and find suspicious processes and ports open on the server
• Install and run Rootkit hunters like chkrootkit, rkhunter etc to look for compromised binaries

I am able to provide these services for you at a negotiable amount.

In all ways I can assure you that this would be a long term business prospect to help both of us grow. Also, if you have any ticketing system and would like me to support your clients, please let me know.

You can contact me via email ani4support@gmail.com. Please let me know if you are interested in this quote. Just drop me a reply and I we can discuss this in detail.


Hope to hear from you soon.

Bye and take care,
ani4support@gmail.com
