If you have an active Hyak and/or Lolo account, you may want some Unix groups created to help you manage access control to your files. The following information will help you create new groups and management the membership of groups that have already been created.

Creating a new Unix group

Contact the iSchool IT help desk and request a new Hyak Unix group. The help desk staff will set up a new UW NetID Group and request to have it paired with a Unix group on Hyak. This can take up to 24 hours. After the pairing is complete, Hyak will sync membership to the new Unix group with membership for the NetID Group that was created. Since this is a shared environment, all of your groups should begin with a consistent short prefix. Your initials would be a good choice.

All iSchool Hyak NetID groups will begin with the stem uw_ischool_hyak followed by your Unix group name. For example: uw_ischool_hyak_rm_somelab is the full NetID Group, while rm_somelab will be the unix group.

Managing membership of your Unix groups

Member management is done through the UW NetID Groups service. The NetID Groups sync with the Unix groups on a regularly scheduled basis. It can take up to 1 hour for membership changes to take effect. There are two options for you to add or remove members from your groups. The first option is to contact the iSchool IT help desk. If you choose to have the help desk staff manage your groups for you, please include the group name and specify that it is an iSchool Hyak NetID Group that needs to be edited.

You can also manage your groups on your own with the UW NetID Groups web interface. The following link will list out all iSchool Hyak groups: Find your group prefix and click the [+] following it to list out all of your Hyak groups. Now click the group you wish to edit and then click the membership tab. Use the Add and Remove fields to add and remove NetIDs from your group’s membership list.

If you do not have access to edit your groups, please contact iSchool IT and provide the full NetID group name and request access to manage membership of your group.

If you have any questions after reading this article or if you need any help, please don't hesitate to contact the iSchool IT Help Desk.
