[Rkhunter-users] Question about PKGMGR

[<abs...@li...>]

Hi,

after a few days, I switched from PKGMGR=NONE to PKGMGR=RPM on several CentOS 
server.
Since this moment I receive every day this kind of alert:

Warning: Package manager verification has failed:
         File: /usr/bin/newgrp
         The file permissions have changed
Warning: Package manager verification has failed:
         File: /bin/ping
         The file permissions have changed


..even if I run "rkhunter --propupd" on those server.
Why?
Thankyou
