Hi Daniel, I cc qserv list as it might be useful for others. 1. From a SLAC machine: ssh [log in to unmask] Qserv is built in ~fjammes/src/qserv -> /sps/lsst (symlink to shared fs -> /sps/lsst/Qserv/fjammes/src/qserv/) 2. and then, from ccqservbuild.in2p3.fr, access to the master node: ssh -K ccqserv100 Qserv is installed in /qserv/stack, see also /qserv/qserv-run-dir 3. and access to the worker node ssh -K ccqserv101 core is here: ls /var/tmp/abrt/last-ccpp 4. sudo su qserv -c "my cmd" should work on all ccqservXXX nodes. P.S.: There might be a way to optimize krb5 use, and allow to connect directly to all nodes with only providing once the password, but my config isn't working fine yet. ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the QSERV-L list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=QSERV-L&A=1
