Then change the shell entry as shown. myuser:*:12:23:guest:/:/sbin/nologin You cannot even login from the root account, you get a message that says: "This account is currently not available." It works well for service accounts that do not require login or user interaction.

Second, useradd will by default create an account which cannot be accessed until a password is added (typically with the passwd command). If you need to lock an account that has a password so that it cannot be used for login, you can use "passwd -l username"; note that this prepends an exclamation mark to the password field (does the same thing as your star). The opposite command is "passwd -u username", which unlocks the account. -Chris -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
