I am not sure why, but this file is originally trying to use the exporter as the sensor for SiLK devices. This is interesting since the PDF above indicated that the @exporter array was only used for flow-tools, not SiLK but alas here it is using it. If anything I think it would make more sense to use the "device" as the sensor, especially since @ipfix_devices is already defined as a sensor per the documentation. To make matters worse it is grepping for the probes and not the sensors in order to populate the --sensors= flag. --- FlowViewer_Utilities.pm.orig 2014-02-18 12:52:42.000000000 -0500 +++ FlowViewer_Utilities.pm 2014-02-18 13:50:09.000000000 -0500 @@ -2339,50 +2339,50 @@ # Set up exporter address filtering, if any - if ($exporter ne "") { + if ($device_name ne "") { - $exporter =~ s/\s+//g; - $num_include_probe = 0; - @valid_probes = (); + $device_name =~ s/\s+//g; + $num_include_sensor = 0; + @valid_sensors = (); - # Get valid probes (exporters) from the sensor.conf file + # Get valid sensors (device_names) from the sensor.conf file - $probe_command = "cat $sensor_config_directory/sensor.conf | grep probe > $work_directory/valid_probes_$suffix"; - system ($probe_command); + $sensor_command = "cat $sensor_config_directory/sensor.conf | grep sensor > $work_directory/valid_sensors_$suffix"; + system ($sensor_command); - open (PROBES,"<$work_directory/valid_probes_$suffix"); + open (PROBES,"<$work_directory/valid_sensors_$suffix"); while (<PROBES>) { - ($probe_label,$probe) = split(/\s+/,$_); - if ($probe_label eq "probe") { push (@valid_probes,$probe); } + ($sensor_label,$sensor) = split(/\s+/,$_); + if ($sensor_label eq "sensor") { push (@valid_sensors,$sensor); } } while ($still_more) { - ($exporter_name) = split(/,/,$exporter); - $start_char = length($exporter_name) + 1; - $exporter = substr($exporter,$start_char); + ($device_name_name) = split(/,/,$device_name); + $start_char = length($device_name_name) + 1; + $device_name = substr($device_name,$start_char); - if (substr($exporter_name,0,1) eq "-") { - &print_error("SiLK software does not support exclusion of Exporters (Sensors) at this time: -$exporter_name"); last; + if (substr($device_name_name,0,1) eq "-") { + &print_error("SiLK software does not support exclusion of Exporters (Sensors) at this time: -$device_name_name"); last; } else { - foreach $probe (@valid_probes) { - if ($exporter_name eq $probe) { - $num_include_probe++; - if ($num_include_probe < 2) { - $sensor_field .= $exporter_name; + foreach $sensor (@valid_sensors) { + if ($device_name_name eq $sensor) { + $num_include_sensor++; + if ($num_include_sensor < 2) { + $sensor_field .= $device_name_name; } else { - $sensor_field .= "," . $exporter_name; + $sensor_field .= "," . $device_name_name; } } } } - if ($exporter eq "") { last; } + if ($device_name eq "") { last; } } $sensor_field = " --sensors=" . $sensor_field; - $save_file .= "_" . $exporter_name; + $save_file .= "_" . $device_name; } # Set up Next Hop IP filtering, if any _______________________________________________ freebsd-ports@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-ports To unsubscribe, send any mail to "freebsd-ports-unsubscr...@freebsd.org"
