I scanned my local network and found that Kali linux was exposing apache2 on port 3000. Its a pretty much vanilla installing running inside Virtualbox on an OSX host
Is this there by default and why does it show powered by CentOS on the test page?
Linux kali 4.0.0-kali1-amd64 #1 SMP Debian 4.0.4-1+kali2 (2015-06-03) x86_64 GNU/Linux
I tried stopping the httpd and apache(2) services but its still running. Very weird!
UPDATE : Further confusion
After a reboot apache was no longer listening on port 3000. Starting it made it available on port 80 and with debian information on the default home page and not centos
