Verify local interactive users on the Ubuntu operating system have a home directory assigned. Check for missing local interactive user home directories with the following command: # sudo pwck -r user 'lp': directory '/var/spool/lpd' does not exist user 'news': directory '/var/spool/news' does not exist user 'uucp': directory '/var/spool/uucp' does not exist user 'www-data': directory '/var/www' does not exist Ask the System Administrator (SA) if any users found without home directories are local interactive users. If the SA is unable to provide a response, check for users with a User Identifier (UID) of 1000 or greater with the following command: # sudo cut -d: -f 1,3 /etc/passwd \| egrep ":[1-4][0-9]{2}$\|:[0-9]{1,2}$" If any interactive users do not have a home directory assigned, this is a finding.

Verify local interactive users on the Ubuntu operating system have a home directory assigned.

Check for missing local interactive user home directories with the following command:

# sudo pwck -r
user 'lp': directory '/var/spool/lpd' does not exist
user 'news': directory '/var/spool/news' does not exist
user 'uucp': directory '/var/spool/uucp' does not exist
user 'www-data': directory '/var/www' does not exist

Ask the System Administrator (SA) if any users found without home directories are local interactive users. If the SA is unable to provide a response, check for users with a User Identifier (UID) of 1000 or greater with the following command:

# sudo cut -d: -f 1,3 /etc/passwd | egrep ":[1-4][0-9]{2}$|:[0-9]{1,2}$"

If any interactive users do not have a home directory assigned, this is a finding.
