NIS configuration

  • domainname ISAC-NIS
  • master: isdaq00
  • autofs/automount configuration: isdaq00:/etc files auto.master, auto.home, auto.local
  • after editing NIS files, run: make -C /var/yp
  • on all NIS clients, there is a script running from /etc/cron.hourly to update the local NIS maps
  • if you do not want to wait 1 hour for the NIS maps to update, login there and run this script manually.

NFS configuration

  • /isdaq/dataNNN - shared data disks
  • /musr/xxx - BNMR/BNQR data disks
  • /iris/xxx/iris - IRIS data disks
  • /emma/xxx/emma - EMMA data disks
