I've been asked by the Nortel guys if there's a good way to push a build to a testbed of machines.
There are at least three such ways! OFW has a multicast mode, which Mitch Bradley can probably point you at documentation for. If you've got a server properly configured, you can have all of your machines reflash their NAND with the build broadcast from the server. For the OLPC mesh testbed, I used the same olpc-update mechanism we use to upgrade machines in the field. http://wiki.laptop.org/go/Olpc-update#Setting_Up_A_Local_Updates_Server describes how to set up a local updates server. By default XOs will query http://antitheft.laptop.org/antitheft/1/ using the protocol described in http://wiki.laptop.org/go/Theft_Deterrence_Protocol which lets you specify which update server to use and how often to query for updates. You can either ensure that your local DNS maps antitheft.laptop.org to a server you control, or patch the build to query a different server. You can then push updated builds to your network of machines. Granted, I used this mechanism for our mesh testbed specifically because I also wanted to exercise our field upgrade code. Other folks have reported success using screen or Konsole to send identical commands over ssh to a large number of machines, which is a lower-barrier-to-entry option. --scott -- ( http://cscott.net/ ) _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
