Ticket #2287 · on-call technician Staff at Brindle Creek Public Library report the reference-desk Linux workstation refdesk-lx (172.20.6.45) is slow to reach the catalog's cloud sync service, while local look-ups feel fine. Your job: confirm which DNS resolver the workstation is using, trace the path to it, trace the path to the internal catalog database, and decide where the delay actually lives. Work entirely from the console. Type help to list available commands.
