Hi, I need to test one specific port on a serie of Ip addresses that I own, I thought about using nmap or telnet, but both return the same value, no matter if the port is open or filtered. Anyone has an idea, before I start scripting to analyse the output of the command? Regards, Ugo
Use nmap. Here I'm scanning my home network for any port 80 that's open nmap -p 80 192.168.1.0/24 Matt Shields Cyberbite Network - www.cyberbite.com On 12/7/06, Ugo Bellavance <ugob at camo-route.com> wrote:> Hi, > > I need to test one specific port on a serie of Ip addresses that I own, > I thought about using nmap or telnet, but both return the same value, no > matter if the port is open or filtered. > > Anyone has an idea, before I start scripting to analyse the output of > the command? > > Regards, > > Ugo > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos >

It will notify you if the host displays any open ports not pre-defined as open for that host. -- - Kevan Benson - A-1 Networks
