    Hi guys,
    i am running ubuntu20.04 with ispconfig 3
    i get the following error after installing rkhunter
    Code:
    Warning: Suspicious file types found in /dev:
             /dev/shm/rhm.c2a3f3edaa8d0b3ff673: None
             /dev/shm/rhm.102601f3844c655dbc61: None
             /dev/shm/rhm.2ff4b4cc0757f2f52ff9: None
             /dev/shm/rhm.7df2c93c5da981109ae5: None
             /dev/shm/rhm.3f2c195e92f8df7d088e: None
             /dev/shm/rhm.b8fc2b53c4af33de47d3: None
             /dev/shm/rhm.086ae52b5fa454f2aee3: None
             /dev/shm/rhm.a5db18ac3017788c32e2: None
             /dev/shm/rhm.4cd1d92b39e933f620ee: None
    
    
    when i add to rkhunter.conf
    Code:
    ALLOWHIDDENFILE= /dev/shm/rhm.4cd1d92b39e933f620ee: None
    or
    ALLOWHIDDENFILE= /dev/shm/rhm.4cd1d92b39e933f620ee
    or
    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.
