However as I saidearlier that "if suppose SMTP isconfigured on port 26 instead of traditional port25, then it wouldadd a twist to this situation". Hence yoursuggested method wouldstill leave some hosts down. Can you kindlyfurther granularize yoursuggestion?But it would turn up with port 25 as "closed" which still shows that the host is alive.Or not! The fw can be configured not to respond in case that a port is closed. In this situation nmap reports the port as "filtered" and you can't tell if the host is up. In fact, a live host with no ports open and with a fw configured to reject icmp can appear as offline.-- Rajat Swarup http://rajatswarup.blogspot.com/------------------------------------------------------------------------This list is sponsored by: Cenzic Need to secure your web apps NOW?
