While running systemctl status
I m getting the message
warning: cannot open /etc/hosts.allow: Permission denied
warning: cannot open /etc/hosts.deny: Permission denied

How can I fix this ?

What is the output from the commands:

uname -a
rpm -V setup

the warning shows when checking systemctl status rpcbind and is also in var/log/messages
and the services cant restart

/etc/hosts.allow and /etc/hosts.deny permission is 644

Any idea??

polkit service also failed shows authorization failed

Can you respond soon? Thanks

Did you run rpm -V setup as root?

Also, from man rpm the M flag means

M Mode differs (includes permissions and file type)

So you have changed the permissions of all of those files listed there away from the defaults. I would suggest not doing that. Perhaps yum reinstall setup or rpm --setperms setup && rpm --setugids setup will restore them to what they should be.

Thanks for the response.You are right there was some mess with permissions.
I tried the rpm --setperm .....option now rpm -V setup shows nothing but
the problem is still there
rpcbind[2349]: connect from 10.0.91.2 to getport/addr(1...st
rpcbind[1078]: warning: cannot open /etc/hosts.allow: P...ed
rpcbind[1078]: warning: cannot open /etc/hosts.deny: Pe...ed
and
● polkit.service loaded failed failed Authorization Manager
● rpc-statd.service loaded failed failed NFS status monitor for NFSv2/3 locking.
● systemd-hostnamed.service loaded failed failed Hostname Service

i didnt restart after the rpm --setperm setup

and after restart or when logging in to a new kernel rpc bind starts ok at first then when nfs starts all the problem shows up again
