Re: nmap scan too slow and -n option

[micro dev <microdev1 () yahoo com>]

Thanks.
But I feel problem here is not related to old version of NMAP coz it is working just fine in 
other subnets. My point was to know what can cause these problems.
I will try with new version also but it will be good if I can know the reasons for the 
problem. I feel it is related to underlying network rather than NMAP. And it will be interesting to know what can cause 
NMAP to scan so slow.

Judging from your nmap version of 3.30 you are close to a year and a
half out of date. 3.70 is the latest version. Download, install.

If you still have problems then come back.
