Problème de Clonage avec UDPCast

Bonjour, Je suis Vannapha, chargé de projet à l'Antenne AUF de Vientiane, je me permet de vous contacter pour m'aider à résoudre mon problème. Je voudrais faire le clonage d'un portable DELL core i5 (sous exploitation Ubuntu 16) sur un ordinateur All in One Dell Core i3 via swhitch en utilisant UDP Cast, mais le problème est que le moment où il faut choisir la la langue, le clavier ne marche plus, même j'ai changé le nouveau clavier. J'ai l'impression que UDP Cast ne connaît pas surtout les pilotes des ordinateurs récents, est-ce que vous avez le moyen de mettre à jour UDP Cast ? La version UDP Cast que j'ai utilisé est daté en 2009. Merci de votre aide. Bien cordialement, -- Vannapha BOUPHAPANYA Chargé de projet Antenne AUF de Vientiane Faculté d'Ingénierie Bâtiment R1 - Campus de Sokpaluang, Université Nationale du Laos BP: 7451 - Vientiane - RDP Lao Tél : (856-021) 31 46 99 Mobile:(856-020) 28 03 51 93 - 020 77 71 31 30 E-mail : vannapha.bouphapanya(a)auf.org ******************************************************* Adoptez l'éco-attitude.

Hi steve Please check the archives and the online documentation. (ie the command line page.) Since you are using Windows, try --max-bitrate bitrate 10m|20m|40m. Etc...

Problem: UDPCast transfer breaks DHCP leases

Hello, We are facing a problem when using UDPCast in multicast mode. When I start a transfer from one pc to another, no problem. But when I start a transfer from one pc to two or more pc's, new booted clients can't get a ip-address from the DHCP-server anymore. We have a rather complicated network, with lots of subnets. I contacted network-support and they presume it could be a conflict with the VVPR (Virtual Router Redundancy Protocol) which also uses multicast. I already played with several settings, like: udp-sender --ttl 1 and udp-receiver --ttl 1 udp-sender --ttl 2 and udp-receiver --ttl 2 udp-sender --mcast-rdv-address 224.0.0.3 and udp-receiver --mcast-rdv-address 224.0.0.3 But the problem persists. The problem only starts when the actual transfer is initiated. While udp-receiver is waiting for the clients to connect there is no problem yet, but as soon as data is being transferred (multicast), new booted clients in the network can't find the DHCP-Server, don't get an IP-addresses, can't PXE boot anymore. I hope somebody understands what is going on here, and if there is a solution. We really need udpcast in our environment. Thanks in advance for all help.
