InformationThe /etc/group file contains a list of all the valid groups defined in the system. The command below allows read/write access for root and read access for everyone else.
The /etc/group file needs to be protected from unauthorized changes by non-privileged users, but needs to be readable as this information is used with many non-privileged programs.
SolutionIf the permissions of the /etc/group file are incorrect, run the following command to correct them:
# /bin/chmod 644 /etc/group
