Hiya, Just joined the list and started using pxelinux. Very cool product!!! I searched the, 8+ MB, archives looking for multicast entries. I know that the pxelinux page says that the support of mtftp in pxelinux isn't in the works but I'm not sure how old/relavant that comment is. I have noticied some comments from H.P.A. describing the difficulties in doing MTFTP. Are there any plans to support MTFTP? The reason I ask is that I would really like to be able to serve tftp via multicast. Does anyone know of any other network bootloaders that use multicast? Do many people see this as a need?

It would save some packets if you boot multiple clients at a time, but would need major effort to get this into pxelinux. Also, if you managed to boot all of your clients with MTFTP, they would also need to get some file systems (maybe root filesystems) via nfs or else, and this definitively doesn't work for nfs, smb and what else you could think of.> Does anyone know of any other network bootloaders that use multicast? Do many > people see this as a need?I don't see this as a need, since tftp works even for booting some hundred machines at a time. You need some sane network structure for this (switched ethernet with a higher uplink to the server), but then it's working as it should, and also this should be standard for modern networks.

Do many > people see this as a need?I'll pipe up and say that we at UMBC are using Norton's Ghost for this purpose -- our computer labs consist of rooms full of identical machines, and updating the image on one machine at a time would be tedious at best. I can also imagine that with the popularity of Beowulf clusters, that a change to the OS would be easier to propagate via multicast to all machines at once (I think I have heard some of the folks experimenting with clusters mention pxe booting, but I'm not sure what tools they use).
