Hi -
Apologies for cross posting (original message on ATLAS distributed
Analysis egroup) - I thought on reflection this question might be more
grid oriented.
I'm trying to access a Root file on our SE via RFIO. I can use rfcp to
download the file, but what I would really like to do is access it from
within Root by calling:
TFile *f = TFile::Open("rfio://epgse1.ph.bham.ac.uk//dpm/ph.bham.ac.uk/home/atlas/atlasscratchdisk/user10/jodypalmer/ganga/user10.jodypalmer.ganga.4998.20100628/user10.jodypalmer.ganga.4998.20100628.TopPhys_TopInputs.pt_18.0._00006.root");
If I do this though root (from either a UI or a WN), root throws the
error:
SysError in <TRFIOFile::TRFIOFile>: file
rfio://epgse1.ph.bham.ac.uk//dpm/ph.bham.ac.uk
/home/atlas/atlasscratchdisk/user10/jodypalmer/ganga/user10.jodypalmer.ganga.4998.20100628
/user10.jodypalmer.ganga.4998.20100628.TopPhys_TopInputs.pt_18.0._00006.root
can not be opened for reading (Connection refused)
And in the /var/log/rfio/log file on the DPM head node I see the
corresponding message:
rfiod[17490]: Could not establish an authenticated connection:
Csec_server_negociate_protocol:
The client did not send an authentication negociation request;
_Csec_recv_token: Received magic: 2002001 expecting ca03 !
Has anyone seen this before (or successfully opened a TFile on a DPM SE
via RFIO in root)?
Cheers,
Chris
