Re: raw-sockets and Win-XP SP2

I have the same problem (even though the grc.com socket test says "full raw sockets are available" under RC2 beta 2) and this was the case under XP SP1 & SP2. However, nmap says no raw sockets available on my dialup (ppp0) connection but on my two nic's (eth0/1) it is rawsock a.o.k.

Like you, I too have to use -P0 and -sT to get any port showing up in the results. Using syn stealth yields no results except saying the ports are filtered. This could be normal I dont know what to expect as I am relatively new to nmap.

Subject: raw-sockets and Win-XP SP2


I have been playing around with Win XP SP2 RC1 and just installed RC2 on my machine last night. I have noticed some trouble with nmap. I have not run a packet sniffer to see what was happening but that definatly sounds like a reasonable explanation. Nmap runs on a Windows XP SP2 RC1 machine have been showing the scanned host is up but with no open ports. If I do a full connect scan then it is able to detect open ports.

I've heard strong rumours that the upcoming Win-XP SP2 will disable
the use of SOCK_RAW sockets for any user (admin included). This
will certainly hurt the use of nmap on Win-XP unless we go with
libnet for all platforms.
Steve Gibson (of www.grc.com) has been talking about the danger
of raw-sockets for years; "... have ANY practical need for raw
sockets" [*] he claims. Yeah right. Seems MS is now listening to
him. Yet for years they have deprecated the use of the ICMP API for
ping-like programs. And advised us to use SOCK_RAW instead. Back
to using icmp.dll again I guess.
I for one will not install the service-pack unless there's a loop-hole
to enable SOCK_RAW again. Anyone with additional info on this?
