Hi Peter
We started with a web cache at Glasgow and it caused similar problems
to those you're experiencing. It took a visit to CERN to get LHCb
software installed properly at Glasgow, so from November 2006 to
January 2007 we were unable to run LHCb jobs. Although we had defined
the standard http_proxy type environment variables, there are
standard pieces of client software which don't use these properly -
in particular there's a problem with python urllib, which caused the
LHCb failures.
In the end we used evidence like this to get an exemption from the
University web cache, and if I were you I'd do the same. If that is
really not possible, then you'll get on a lot better if you set-up a
transparent squid cache on the cluster, instead of having to rely on
all VO's client software behaving properly.
Cheers
Graeme
