Configuring the system
2.3 Configuration file "basesys.ini"
LogFileLimit
The size of the system log file /var/log/messages can be restricted with this variable. By
entering "Zero", the log file has no size limitations.
The specified limit is no hard limit for reasons of efficiency but rather a sort of target value. If
the log file reaches the target value times factor 1.5, then it is reduced to around 75% of the
target value. A check is carried out every two minutes maximum to see if the file has become
too large.
Value:
Default:
FirewallOpenPorts
Here you can specify a list of the ports which is to be enabled in the firewall of the external
network interface. The protocol is "TCP" or "UDP", the port is the (numerical) port number of
the service to be enabled. Several entries are separated by blanks.
Value:
Default:
NOTICE
Security risk
Note that opening the ports in the firewall can represent a security risk. Only enable the ports
that you actually require.
Note that every accessible service can have security gaps.
DisableSubsystems
Using this variable, you can suppress mounting and starting of certain subsystems (CFS
systems). Several subsystem names can also be specified - separated by blanks.
Value:
Default:
The names can either be simple CFS basic names (e.g. "nck"), whereby all CFS systems with
this name are ignored. Alternatively you can specify an absolute path (e.g. /siemens/
sinumerik/nck) referring specifically to this CFS system.
It is also possible to set "DisableSubsystems=all" whereby not a single CFS system can be
mounted or started any more.
