Yes but to check for several RB's in a timely fashion it is much
easier to upload a script and execute it. For that I use the CE gridftp
server.
As I said, it can be done by other means (ie sending a command
that downloads the script and a second command that executes it). But
since gridftp servers were supposed to be running it was easier the
other way around.
If it is finally decided that CE's should not run gridftp
servers it is fine with me, I will change my test. For the moment this
is part of an LCG CE configuration and I think I must report if I find a
site were it is not the case. The initial mail was directly to Nikhef,
and Jeff was the one that open the discussion, which I find the
appropriated way thing should go.
Now like in other similar cases we need a way to get to an
agreement and implement it in future releases.
