If we give command ./nikto.pl -Help or perl nikto.pl -Help then we get details and all options.
Simply We are going to scan our own company’s website … because we are pentesting it. So easy:
root@bt:/pentest/web/nikto# ./nikto.pl -h target.com :
I have tested it on my localhost for pasting here, There are output/vulnerability we may get:
root@bt:/pentest/web/nikto# ./nikto.pl -h target.com

As you can see there are many thing Nikto found out. Nikto is very effective for finding default file,directory.
Note: you have to understand the output of tools otherwise you can do nothing.
we can use various options(see help)…. For example a command:
root@bt:/pentest/web/nikto#./nikto.pl -host target.com -root /admin -port 443 -evasion 1
How is this working ? Simple:
-host=-h(The target site)
-root=send all request to /admin directory
-port = The site is not running on default 80 , I know it is running on 443.
-evasion=IDs evasion. Evasion 1(Random URI encoding (non-UTF8))
I hope you got some idea about it… Just try to believe that Learning to use tools peoples does not need hacking training.
If your mind is skid then tools may not help you.. . Be aware about that before using tools .
