Virtual Servers

I read in Hacking Exposed Web Applications 3 that you could detect virtual servers by port scanning. However, I haven’t been able to find how to do this. Can anyone help me?

Nmap is the “standard” utility and I recommend learning how to use it because many other utilities that perform the same basic task use the same options as nmap.
Of course, everyone is different and maybe not using Linux (or MacOS). In windows, Windows subsystem for Linux can provide access to Linux utilities like nmap. There is even a WSL for Kali Linux which has many more tools already I installed.
Just have windows? PowerShell cmdlet Test-NetConnection will test ports too!

Thanks kamsalisburyit. I’ll look into it.
