Re: How to tweak tools against targets that block ICMP

[Naruto Uzumaki <ageofnaruto () gmail com>]

These tools send ICMP packets to detect if a host is alive. However,
if ICMP is blocked most of these tools have the functionality to
either stop pinging and carry on with their main task or send
different protocol packets like TCP and UDP to detect the host. For
eg. you can disable the Nmap ping, which sends ICMP+TCP SYN using -P0
(it's a zero) option.

Read the tool documentation. Usually, there is some command to disable ping.

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are 
highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
