    Hi guys,
    i am running ubuntu20.04 with ispconfig 3
    i get the following error after installing rkhunter
    Warning: Suspicious file types found in /dev:
             /dev/shm/rhm.c2a3f3edaa8d0b3ff673: None
             /dev/shm/rhm.102601f3844c655dbc61: None

             /dev/shm/rhm.4cd1d92b39e933f620ee: None
    when i add to rkhunter.conf
    ALLOWHIDDENFILE= /dev/shm/rhm.4cd1d92b39e933f620ee: None
    ALLOWHIDDENFILE= /dev/shm/rhm.4cd1d92b39e933f620ee
    ALLOWHIDDENFILE= /dev/shm/rhm
    i still get the same error suspicious file types found.
    What am i doing wrong and do i have to worry about these files after install a fresh server?
    thanks a lot for your kind help

    ALLOWHIDDENFILE is probably the wrong directive, those aren't hidden files. You need to use either a wildcard or directory based match, not specific file names. Search for the error and you'll find examples of how to configure rkhunter to ignore those if needed.
