Hi, This is probably a dumb question, but here goes... (I am used to it ;-)
For various reasons, we are configured without private interconnect, ie. on shared LAN. Also do not have DHCP setup across the whole network for Sun Ray configuration. We have been using the GUI firmware to aim the DTUs at appropriate Sun Ray Servers / FoGs -- we have multiple of them, so need to be able to aim individual DTUs at specific servers. We would like to be able to push the GUI firmware out to the DTUs, in order to update all for SRS 5 in this case, rather than drag each unit back to lab and direct connect them to a particular server. I have not been able to figure out how to do this from the Sun Ray documentation, and have not managed to find it on wiki either. Perhaps I am blind. Have tried various combinations of utfwsync, utfwadm, utfwload, and all are complaining that there is no direct interconnect -- "no action taken". I have also manually copied the gui firmware files from /opt/SUNWut/lib/firmware_gui to /tftboot/ directory, and set the DTUs firmware server to the address of our server (using the ctl-break-M trick). Powercycled the DTUs, reboot the server, etc. No joy so far. I have also considered un-configuring the server for LAN access, and trying to trick it into thinking it has a direct connect (utadm -a), then set it back to LAN. But this seems risky. I have a feeling I am missing something obvious here, or just don't know the right magic incantation. So, the question is: Is there a reliable method to force firmware updates out to DTUs across LAN? Same question will inevitably also come up for teleworker case too, across the DTU-embedded VLAN. Any help on this would be great. -- Peter
