Port scanner

alon005 · 10-14-2004, 10:07 PM

Could someone recommend a scanner to scan subnet for a particular service please. There used to be an option with nmap:

nmap -sP -PT80 192.168.5.0/24 for example

I can't find this option in the current version of nmap, Are there any other scanner that provide this option?

Thanks

I think you just do -p 80 instead of -PT 80 to scan for web servers, for example.

From man nmap pages:

Code:

       nmap -sX -p 22,53,110,143,4564 198.116.*.1-127

       Sends  an  Xmas tree scan to the first half of each of the
       255 possible 8  bit  subnets  in  the  198.116  class  "B"
       address  space.   We  are  testing whether the systems run
       sshd, DNS, pop3d, imapd, or port  4564.   Note  that  Xmas
       scan  doesn't  work  on Microsoft boxes due to their defi_
       cient TCP stack.  Same goes with CISCO, IRIX,  HP/UX,  and
       BSDI boxes.

This is with nmap version 3.7 btw.
