Hello,
I have not found a solution yet and appreciate every suggestion to 
pinpoint this problem or avoid it.
I tried among the test posted 10 days ago:
- compile and run on another redhat 9 machine: problem reproduced
- compile and run on a knoppix 4.0.2 harddisk install: same behaviour

older version 3.81 (3.30) out of the box or compiled are working.



PS: Thanks for your answer, shiva Prasad, but I assume your test is not 
comparable, because it is running on XP, using SYN scan not ARP and it 
stopped with an error running  out of ports.
