Error code: x109

Internal designation: EC_INCOMPATIBLE

Description: One or several components of Dr.Web for UNIX cannot operate properly. There is software that impedes their operation in your system.

To identify the possible cause and the circumstances of the error, refer to the Dr.Web for UNIX log (by default, it is located in the /var/log/syslog file or the /var/log/messages file, depending on OS). Also, you can use the command drweb-ctl log.

Resolving the error

1.If this error is caused by SpIDer Gate, an incompatible program may be running in the operating system. This program may generate rules for the NetFilter system firewall, which prevents SpIDer Gate from correct operation. Probably, you have Shorewall or SuseFirewall2 installed in the system (in SUSE Linux OS). The application that configures the NetFilter system firewall may check the integrity of the specified rule system and rewrite it. This may be the main reason of SpIDer Gate conflict with such applications.

Reconfigure the incompatible software lest it interfere in SpIDer Gate operation. If it is not possible, disable the software lest it load at the operating system startup any more. You can try to configure the SuseFirewall2 application (in SUSE Linux OS), following the steps below:

1)open the configuration file of SuseFirewall2 (by default, this is the /etc/sysconfig/SuSEfirewall2 file);

2)find the following lines:

# Type: yesno
#
# Install NOTRACK target for interface lo in the raw table. Doing so
# speeds up packet processing on the loopback interface. This breaks
# certain firewall setups that need to e.g. redirect outgoing
# packets via custom rules on the local machine.
#
# Defaults to "yes" if not set
#
FW_LO_NOTRACK=""

3)Set the FW_LO_NOTRACK parameter value to “no”:

FW_LO_NOTRACK="no"

4)Restart SuseFirewall2:

# rcSuSEfirewall2 restart

Note that if the FW_LO_NOTRACK option is missing in SuseFirewall2 settings, stop the application and disable its launch at system startup.

After reconfiguring or disabling the conflict application, restart SpIDer Gate.

2.If the error is produced by another component, disable or reconfigure the incompatible software so as to prevent any interference with the Dr.Web for UNIX operation.
