Hi everybody, i'm using udpcast successfully since last year to deploy windows partitions in our university. The classrooms i manage are in different vlans, so now i store the partition images on many server inside every single vlan.

What i'd like to do now is to have a single server with vlan support on its nic to do all the job. Well this seems not to work :-( I mean: i can start the udpcast session, i see the clients connetting, i start sending data (which arrives to the clients) but it seems that the replies get lost somewhere... i get for every single client a "Timeout notAnswered ... notReady".

The net guys here say that the net is correctly configured... Finally: i'm doing something wrong? Does udpcast work on vlans (oh, i'm using version 2005-02-26)? Experiences?

My understanding of vlans is not that much - I know we have them too and they seem to work ok. Basically if I understand you correctly you have a vlan capable network card (or support in yoru kernel or something).

Question 1: Do you have an IP on each of the vlans you would like to cast to?

Question 2: Is it really needed that you be on the same vlan? I thought udpcast can make use of multicasting - which would in fact be able to go across routers, but the routers need to support multicast.

Perhaps the clients are answering to the local broadcast address which the server then won't pick up (I've always casted on the same vlan so I'm not too clued up with the intricasies of the udpcast protocol) since it's on a different vlan?
