Symptoms
-
Plesk Repair Kit error:
CONFIG_TEXT: There are incorrect permissions on some items: /dev/log
-
Plesk Outgoing Mail Control does not block mail messages according to limits: it is possible to send more emails than is defined in Outgoing Mail Control limit
Cause
Incorrect permissions and ownership for /dev/log socket file.
Resolution
-
Connect to the server via SSH;
-
Change the permissions and the ownership:
# chmod 666 /dev/log
# chown root:root /dev/log
If permissions are changed back to incorrect
There are some 3rd-party firewall tools installed on a server.
For example, lfd (Login Failure Daemon) that works with csf (ConfigServer Firewall) can cause such behavior. There is parameter ‘RESTRICT_SYSLOG’ identified in the csf configuration file /etc/csf/csf.conf that is causing the issue:
RESTRICT_SYSLOG = "3"
To fix the issue in this case, either stop lfd service, or configure csf so that syslogd files are ignored (check csf documentation if required). Then, change permissions to correct ones:
# service lfd stop
# chmod 666 /dev/log
# chown root:root /dev/log
# ls -la /dev/log
