At the moment config_server thinks it's a run controller. I presume running as part of SctRodDaq should start it properly. For running stand alone, something like: config_server -P SctRootSegmentController -s SCTRootSegment_no_dcs -n config_server should work...
From Chris:
The argument following the "-s" will probably need altering slightly to account for changes in TDAQ14_BRANCH introduced last week to get the dcs/nodcs/ttcvi segment in-out switching working. Probably it needs to become something like "SctCoreSegment".
