Echo UDP

I have found the following line command on router 2600 series to enable the router to reply to an Echo UDP port 7:

"service udp-small-servers"

But this command only enables the router to reply to an UNICAST Echo UDP not to a BROADCAST Echo UDP. Is there a command to enable the router to reply to a BROADCAST Echo UDP ?

Re: Echo UDP

Hi, Santo, I doubt the broadcast Echo UDP is legal traffic. It will be dropped before being responsed.

Re: Echo UDP

Yes, you are right.

But you would like to use this feature in a very particular case where our router is in a private network not connected to the INTERNET.

This feature enables a hosts to know all the nodes attaches to a network: all node which respond to the broadcast echo UDP is known as attached to the network (including router interface).

OK, it is not very legal. But does a command exist to do so ?

Re: Echo UDP

AFAK, no such command to enable it. Sorry for that, man.
