You should be able to do that with either globus-job-run or gridftp, unless things are very messed up it should be the same for both. > Another source of problems is connectivity with RB's, > thus I use > the above commands to upload a script to each CE supporting LHCb (and > publishing a queue in "Production") and checking the connectivity via > globus-url-copy commands. I think CEs always talk to the gridftp server on the RB, not vice versa, so you should be checking outbound gridftp connections rather than inbound. Stephen
