I am probing a host using OpenBSD 3.9-release's netcat.
# nc -v -w 3 -z host.com 80-81 If it finds port 80 open and 81 closed it sits there in an endless loop for about 1 minute and 10 seconds and after that it gives a connection time-out error. # nc -v -w 3 -z host.com 80-81 Connection to host.com 80 port [tcp/www] succeeded! nc: connect to host.com port 81 (tcp) failed: Connection timed out there is no firewall blocking either end of the connection. How can I make this timeout a bit faster? I am already telling it to bail out after 3 seconds with ( -w 3 ) but seems like it is not helping.
