If this is not documented, and I could not find any documentation, some more information about mapping of users, reasons for ssh etc would be useful. Perhaps I'm thick, but this is not obvious. Would starting a server as user 'sage', at boot time, creating files as user sage1, using something like the following: cd /home/someuser su - someuser /home/someuser/sage-4.2/sage - notebook (address='', server_pool=['sa...@localhost'], ulimit='-v 500000', accounts=True) & seem sensible? (I'm hoping this can go into the background, otherwise it will increase boot time). That ensures. 1) The process does not run as root, but as user 'sage', despite the fact root starts the sage server at boot time. 2) Worksheets are created with a different user 'sage1'. BTW, I will look tomorrow at creating a zone on 't2' once again. I'll probably reboot t2 first, to clear it of any mess. I'm not over keen on doing this in the global zone, just in case someone manages to find an exploit. Today I set up a zone on my Blade 2000, using the same subnet (192.168.x.x) for the zone as the main machine. It worked first time. I can ssh to the zone. I'll probably try Sage out later today in the zone. I just *might* have a fix for the problem which stops Sage building if Sun Studio is installed. Someone on the SCons list has suggested something which I have not tried, but might work. But I've had so many issues with SCons, and suggestions from others rarely working, I'm not holding my breath. Hopefully we can get Sage running on t2 very soon. All we need then, it a nice task well suited for parallel computing, which we can use. Then hopefully get some of the power of that machine, as currently it is not being use to its full capability.
