Linux and UDP

[and_woox]

Please i'm creating a script and some people are telling me that linux based machines dont handle the udp protocol, is this right?

So basically what the implicants of using the'' -p udp'' on my script?

Thanks

I use UDP extensively on my P2P apps, and I have no issues at all... most likely the people that told you so had problems enabling udp communication through their iptables. It isn't difficult to configure it, though.

So do you think this script can work well?

 

iptables -I FORWARD -s 192.168.1.2 -p udp -m connlimit --connlimit-above 100 -j DROP
