RE: Problems with adjust_timeout

[Matt Marshall <mmarshall () redspin com>]

Hi,

I need to scan a bunch of hosts that are behind snort/hogwash active 
connection blocking IDS.  For the scan I am using:

nmap -sS -F -P0 -T0 -oN hostname_IP -S xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx

I am using a bunch of different IP addresses and specifying a source 
address with -S.

I am getting the following mssg from nmap:


RTTVAR has grown to over 2.3 seconds, decreasing to 2.0
Serious time computation problem in adjust_timeout ... received = 
(1100901829, 789378) sent=(1100901829,788050) delta = -300180238 srtt = 
262659036 rttvar = 2000000 to = 300000000
QUITTING!
