udpcast

UDPCast allows to send data simultaneously to many destinations on a local net. This can for instance be used to install entire classrooms of PCs at once. The advantage over using other methods (nfs, ftp, whatever) is that udpcast uses Ethernet's multicast abilities: it won't take longer to install 15 machines than it would to install 2. The tool comes with a busybox bootdisk for easy loading of the tool. However, udpcast can also be started from the command line of an already installed system, and can be used for other purposes than just system installation.

    Release Notes: The ability to boot off USB media (and save its config there, just like on floppy). The ability for the sender to start a boot server (DHCP + TFTP) off of which the receivers can now boot (only available for the USB or CD images). Busybox is now compiled against uclibc, which leads to much smaller sizes. Thus, the pre-built udpflop.img is now back, with the most frequently used net and disk modules included.

      Release Notes: Statistics are printed less often (only once every half second or at a configurable interval). A workaround was made for an lseek bug on Linux. A longer DHCP timeout is used in order to deal with slow switches.
