1. Before we start working on this tool,we need to first get clear of what exactly is
Load Balancing?
2.
Load balancing is a method to distribute workload over multiple computers , network links, central processing units, disk drives, or other resources, to achieve optimal resource utilization, maximize throughput, minimize response time, and avoid overload. So before any one performs a penetration test, some recon work needs to be done on the target domain to make sure it does not have the ability to misdirect any probes and attacks.
About the Tool : LBD
3. LBD (Load Balancing Detector) is a small script that tells if a given domain uses DNS and/or HTTP Load-Balancing (via Server: and Date: header and diffs between server answers). The main purpose of the tool is to check if the given domain uses load balancing.In other words when a server uses load balancing to distribute its work load over multiple systems, it should not get clogged up with excessive requests that prevents disruptions. This will mostly be applicable to renowned websites to reduce their system workload and to prevent malicious DOS attacks.
Usage :
./lbd [Domain]
4. I could not find any switch option that can be used with the command ....so the usage is simple....I have tried this on two sites : certifiedhacker.com and dvwa.co.uk.Screen shots of the results obtained are seen below :
