Buffer space Problems
From: <joeclifton () bellsouth net>

Any help is appreciated.  

My Command line: 

nmap -sP -PI -oA ping-

Obvisouly, I am running out of buffer space somewhere, but where is my question, and is there a solution, except to 
reduce the size of the subnet being scanned.  I first tired -T4, and backed it all the way down to -T1, with almost no 
difference.  I get lots of hosts returned as being up, then it starts giving me the error below.  I have tried 
different size subnets, and the largest I can scan with out geting the error is /22.

I sometimes get an error similar to #2 below. (can;t remember the whole thing, and forgot to copy it.)

I scan a lot of large subnets, and would like to ge this resolved.
Is there another way to throttle back, besides the timing option?  I hate having to do 20 or 25 smaller scans, then 
cat'ing them together.

error #1

sendto in sendpingquery returned -1 (should be 8)!
sendto: No buffer space available

error #2

My versions:

nmap version 3.48 

Linux xxx.xxxx.org 2.4.22-1.2174.nptl #1 Wed Feb 18 16:38:32 EST 2004 i686 i686 i386 GNU/Linux   (Fedora Core 1)

Thanks again for any help....
