Re: Nmap on VPS

I have seen several VPS hosting companies that cripple scanning tools by tweaking various Linux kernel Capabilites 
flags.  We haven't had much luck bypassing them and it likely violates terms of service and would get you booted anyway.

Good luck,

Tom

Hello,
I have a virtualized server (VPS). I use this server to host my blog. I have installed Nmap...But it looks like that 
Nmap is not working proprety. When I scan my office (without root privileges), Nmap reports me some open ports. No 
problem yet. But if I scan as root, Nmap say that allscaned ports are closed. 
I did the same kind of scan for both (priviliged e non priviliged)I scan a OPEN port with root privileges and Nmap 
port report filtred. 
The truth is that some ports are really open. 
BTW: I did a normal installation: yum install nmap5.21.rpm
Does anybody knows what is happening?
