    Shouldn't it be quarantine_hits and not quar_hits though?
    Code:
    [[email protected] ~]# cat /usr/local/maldetect/conf.maldet | grep quar_hits
    [[email protected] ~]# cat /usr/local/maldetect/conf.maldet | grep quarantine_hits
    quarantine_hits="1"
    # [NOTE: quarantine_hits=1 required]
    # [NOTE: quarantine_hits=1 required]

    can you post a sanitized copy of your /usr/local/maldetect/conf.maldet to gist or pastebin seems the config file settings might have changed from what i posted in 1st post of this thread. Is this on centos 6 or 7 ?

    Yup it has indeed changed. Running CentOS 7.2 but checked on my CentOS 6 server and the config is the same. Seems to have changed in some version of maldetect.

    Using clamdscan returns a permission error for me, the capital X also doesn't seem to adjust the permissions.
    Code:
    #!/bin/bash
    
    sed -i 's|^#CallUploadScript yes|CallUploadScript yes|g' /etc/pure-ftpd/pure-ftpd.conf
    
    cat >/etc/pure-ftpd/clamscan.sh<< EOF
    #!/bin/bash
    /usr/bin/clamscan --remove --quiet --no-summary "\$1" --log=/var/log/clamscan-pureftpd.log
    EOF
    
    chmod +x /etc/pure-ftpd/clamscan.sh
    
    pure-uploadscript -B -r /etc/pure-ftpd/clamscan.sh
    
    echo "pure-uploadscript -B -r /etc/pure-ftpd/clamscan.sh" >> /etc/rc.local
    
    service pure-ftpd restart
    
    then chmod +x and run script
    Code:
    chmod +x setup-callupload.sh
    ./setup-callupload.sh
    In short, if this doesn't work for anyone, try to change clamdscan to clamscan and the capital X to x.

    I've started to using maldet today and when i look the "/usr/local/maldetect/conf.maldet" configuration file, i can't see or find these values like;

    Code:
    email_subj="maldet alert from $(hostname)"
    and

    Code:
    # [ QUARANTINE OPTIONS ]
    quar_hits=1
    
    # Try to clean string based malware injections
    # [NOTE: quar_hits=1 required]
    # [0 = disabled, 1 = clean]
    quar_clean=1
    
    # The default suspend action for users wih hits
    # Cpanel suspend or set shell /bin/false on non-Cpanel
    # [NOTE: quar_hits=1 required]
    # [0 = disabled, 1 = suspend account]
    quar_susp=0
    # minimum userid that can be suspended
    quar_susp_minuid=500

    why? They are default and not important on latest version?

    Centos 7.2 and centmin mod 123.09beta01.

    I installed the maldet to my another server which running on centos 6.5 and cpanel, i see these options even so. But i can't see these options from centmin mod maldet installer.

    added a note to first post too https://community.centminmod.com/posts/3761/ for changes in variables

    centmin mod maldet addon just installs official maldet so config options are whatever maldet's recent version supplies and is accounted for already in maldet.sh addon from updates done 20 days ago - history for maldet.sh addon commits at History for addons/maldet.sh - centminmod/centminmod · GitHub

    You only update clamav definitions not the version as you can't update the version as it's using clamav rpmforge package which does not have a newer version that 0.98.4. 0.99.2 is not available in rpmforge yum repo. Other yum repo's clamav packages maybe newer but their file and directory structure differs and can break a few things for centmin mod.

    clamav use about 500MB ram all the time.
    Is it wise to stop clamav and (somehow) start only when need it (when maldet need it)?
    So, how to stop clamav from automatic start on boot
    How to stop it right now
    How to start it right now

    Code:

    Should get you a status, then swap status for stop or start.

    Is 500MB alot of ram, whats your total?

    It seems that run every 10 minutes, but 500MB ram is consumed all the time


    Any chance to setup in that way so it uses 500MB but not all the time?

    AFAIK, that's normal for clamav which is used by maldet as a speedier scanner as outlined at https://community.centminmod.com/posts/3761/ but you can also read that link to disable clamav and let maldet natively scan instead - it's alot slower though as Clamav scanner is 4x times faster than maldet native scanner.

    in /usr/local/maldetect/conf.maldet disable clamav
    Code (Text):
    # Attempt to detect the presence of ClamAV clamscan binary
    # and use as default scanner engine; up to four times faster
    # scan performance and superior hex analysis. This option
    # only uses ClamAV as the scanner engine, LMD signatures
    # are still the basis for detecting threats.
    # [ 0 = disabled, 1 = enabled; enabled by default ]
    clamav_scan=0

    then disable clamd service
    Code (Text):
    service clamd stop
    chkconfig clamd off

    Maldet is not in real time? I mean, it is not scanning 0/24h in real time.
    If not, is it possible to enable automatically clamd service when maldet need it?
