prashanlk · 01-16-2008, 12:39 AM

Hi all,

I need to open UDP port 1194 in my opensuse 10.2 mahine.i applied the below command to open it.

iptables -I INPUT -p UDP --dport 1194 -j ACCEPT

but it's not opened.when i scan the UDP port list using nmap i got the following output.

#netstat -an --inet | grep 500
#nmap -sU -p 1194 192.168.1.110

PORT STATE SERVICE
1194/udp closed unknown

why it's not opening..?can any one help me on this?

Thanks

According to nmap documentation this means that the port is open is accessible (so he iptables rule is OK) but there is no application listening on it.
