Specifically the success I've had with a test bed of eight units was with distributed shell, aka http://www.netfort.gr.jp/~dancer/software/dsh.html debian package dsh ... either preload the image with keys for a remote accessor, or add a key to each newly reimaged laptop. To reboot the entire test bed ... "dsh --group xo reboot" I've also used a time synchronisation script in earlier builds, might no longer be necessary ... by placing an rdate binary in /usr/local/bin and then ... dsh --group xo --concurrent-shell "/usr/local/bin/rdate 10.0.0.1 && hwclock --systohc && cp /usr/share/zoneinfo/Australia/NSW /etc/localtime && date --rfc-3339=ns" The distribution of the output is then useful to determine how well the time was set across the test bed. Running it a second time gives better synchronisation, since everything is in memory. -- James Cameron mailto:[EMAIL PROTECTED] http://quozl.netrek.org/ _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
