The hello packets contains other parameters than just the multicast address (such as blocksize and capabilities). So, the -m option is not enough to convey all information that is in the HELLO packet

Hi All,

I want to use udpcast in unicast (or pointopoint) mode.

However, I do not want udp-sender to determine whether to use unicast or multicast based on the number of connections coming from the clients since I want to test udp-sender along with another application on the receiving side other than udp-receiver (In this framework, there won't be any connections coming from the clients).

Based on above, I want udp-sender to use the unicast destination IP address provided by the user from the command line or it may be even hard-coded into the source code.

I tried to use -m option to specify a unicast address instead of a multicast address to "trick" udpcast.

But, it did not like that. I guess that it got some kind of negative feedback from the existing udp-receiver clients, and aborted the transfer since the clients were expecting a "proper" multicast address after -m option.

Any ideas to overcome this issue ?

Thanks.
