# Config options can be set on the command line, via environment variables
# and via a configuration file like this one.  The order of precedence is:
# command line, environment variables, configuration file.
# Equivalent variables are listed in the description of each parameter.
#
# A configuration file can be specified on the command line or with
# the environment variable RS_CONFIG_FILE.

# dynamic parameter, but updated values will only apply to new
# connections.
# Equivalent environment variable: RS_TIME_WINDOW_LIMIT

#TimeWindowLimit 100


# Define the base directory for data transfer logs including both
# data transmission and reception logs.  By default no logs are written.

# count sent to and/or received from each client during the log interval.
# If this parameter is specified and the directory exists, files will
# be written at a user defined interval with the format:
# "<dir>/[prefix-]txlog-YYYYMMDDTHHMM-YYYYMMDDTHHMM" and

# if write permission is granted.  This parameter can be specified
# multiple times and should be specified in address/prefix (CIDR)
# notation, e.g.: "LimitIP 192.168.0.1/24".  The prefix may be omitted

# Specify IP addresses or ranges which should be specifically allowed
# to connect while all others will be rejected.  By default all IPs
# are allowed to connect.  This parameter can be specified multiple
# times and should be specified in address/prefix (CIDR) notation,
# e.g.: "MatchIP 192.168.0.1/24".  The prefix may be omitted in which
