Re: [Condor-users] Understanding PrivSep permissions



I think originally they intended to have PrivSep everywhere
but haven't finished the submission side of it.  Look at CondorWeek 2007
presentations, probably Zach Miller's talk that year.

Hi folks,

I've been reading the PrivSep wisdom on the following Condor wiki page:

 http://condor-wiki.cs.wisc.edu/index.cgi/wiki?p=PrivSep

My first question is about this line: "The submit side daemons must still
run as root unless there is only a single submitter or all submitters are
trusted (i.e. a personal Condor)." Is the reason for this to have the
necessary permission to read and write the log files?

My second question is about this line: "For a single Condor instance to
have both (multi-user) submit-side and execute-side functionality either
PrivSep must not be used or the Master must still run as root and be
configured to start the StartD without root (via the STARTD_USERID
setting)." I don't understand why PrivSep should not be used for both
submit and execute nodes. Can someone elaborate?
