Installation

Installation Problems

  1. You can re-run the installer / updater from the command line to check for any errors:

Centos / RHEL / CloudLinux

/usr/local/psa/admin/bin/modules/warden/install.sh

Debian / Ubuntu

/opt/psa/admin/bin/modules/warden/install.sh
  1. Try restarting the ClamAV daemon and ClamAV milter services and check for any errors:

Centos / RHEL / CloudLinux 7 (systemd)

// clamav restart 
systemctl restart clamd@scan.service

// clamav log file
tail -f /var/log/clamd.scan 

// clamav-milter restart 
systemctl restart clamav-milter.service 

// clamav-milter log file
tail -f /var/log/clamav-milter.log 

Centos / RHEL / CloudLinux 6 (sysvinit)

// clamav restart 
/etc/init.d/clamd restart

// clamav log file
tail -f /var/log/clamav/clamd.log

// clamav-milter restart 
/etc/init.d/clamav-milter restart

// clamav log file
tail -f /var/log/clamav/clamav-milter.log

Debian / Ubuntu

// clamav restart 
/etc/init.d/clamav-daemon restart

// clamav log file
tail -f /var/log/clamav/clamav.log 

// clamav-milter restart 
/etc/init.d/clamav-milter restart

// clamav log file
tail -f /var/log/clamav/clamav-milter.log

Cannot Send Email After Installation

  • Impossible to send or receive the email on the server.
  • Local delivery does not work.
  • Records like the following can be found in /var/log/maillog
    Apr 18 22:21:37 youruserver postfix/cleanup[13406]: E96C852200CB: milter-reject: END-OF-MESSAGE from localhost.localdomain[::1]: 4.7.1 Service unavailable - try again later; from=<from@example.com> to=<to@example.com> proto=ESMTP helo=<webmail.example.com>

    This means that the ClamAV milter is running but cannot connect to the ClamAV daemon to scan the message for viruses so the message is rejected. Stopping the Anti-virus milter on the Warden dashboard should allow mail to be sent and received again.

Common Problems

Not enough memory to start the ClamAV daemon:
If you see Cannot allocate memory in your ClamAV daemon logs this means that you do not have enough free memory in order to start the ClamAV daemon. Free up some memory on your server or upgrade your system memory then restart the Anti-virus service and Anti-virus milter service.

# grep 'Cannot allocate memory' /var/log/clamd.scan 
Sun Feb 10 03:15:52 2019 -> ERROR: daemonize() failed: Cannot allocate memory
Sun Feb 10 03:25:51 2019 -> ERROR: daemonize() failed: Cannot allocate memory
Sun Feb 10 03:32:12 2019 -> ERROR: daemonize() failed: Cannot allocate memory

Incorrect permissions your /var/tmp or /tmp directories used by the ClamAV and ClamAV Milter:
If you see Failed to create temporary file in your ClamAV daemon or ClamAV milter logs this means that your /var/tmp or /tmp permissions are not writable by the ClamAV daemon or ClamAV milter.

# grep 'Failed to create temporary file' /var/log/clamav-milter.log
Thu Apr 18 22:31:55 2019 -> ERROR: Failed to create temporary file
Thu Apr 18 22:31:55 2019 -> ERROR: Failed to create temporary file

To fix the tmp permissions change the permissions then restart the ClamAV daemon service and ClamAV milter service:

chmod 777 /var/tmp /tmp

Un-installing

You can run the uninstaller from the command line to completely remove the extension:

Centos / RHEL / CloudLinux

/usr/local/psa/admin/bin/modules/warden/uninstall.sh

Debian / Ubuntu

/opt/psa/admin/bin/modules/warden/uninstall.sh
