hello All,

i installed nmap 4 from source. ran a scan:

[root () d root]# nmap -sV -T5 -p 22 192.168.3.0/24

Starting Nmap 4.00 ( http://www.insecure.org/nmap/ ) at 2006-02-02 18:08 MST
Got nsock WRITE error #32 (Broken pipe)

Got nsock WRITE error #32 (Broken pipe)

Got nsock WRITE error #32 (Broken pipe)

Got nsock WRITE error #32 (Broken pipe)

Got nsock WRITE error #32 (Broken pipe)

Strange connect error from 192.168.3.41 (32): Operation now in progress
nmap: nsock_core.c:273: handle_connect_result: Assertion `0' failed.
Aborted

so i used 3.95 from another machine and got the same error. i used
3.83 from a third machine and got the same error. i ran several tests
the same ip is not repeated in the error (from any version). may be i
just have'nt run enough tests to start seeing the cycle.

i have used nmap to scan the above ip space before, (as late as last
week) and never gotten this message before.

i ran the scans w/o the -sV option and there are no errors.

any thoughts ?

monzy
