Hi! I'am using udpcast to transfert disk Images from a server to several clients. The server box has one Network card and several virtual interfaces (eth0, eth0:0, eth0:1...). When I try to send a file to one client through one of the virtual interface(eth0:x) everything goes well. But when the client number increases (more than one) I get an error saying: Rogue packet received <eth0 IP address>:9001 expecting <eth0:x IP address>:9001 The command line used on the server is : udp-sender --file <filename> --interface eth0:x On the client: udp-receiver --file <filename> It seems that only the eth0 interface can be used bay udpcast. It works perfectly with this one. How can I get udpcast to work with my virtual interfaces Sorry for my bad English! Thank you for your help. regards Alex
