This option allows the time to be set to any value without restriction; however, this can happen only once. If the threshold is exceeded after that, ntpd will exit with a message to the system log. This option can be used with the -q and -x options. See the tinker command for other options. -i jaildir

The purpose is to allow gpsd to start without editing /etc/conf.d/gpsd. Note that while gpsd will now start without editing the conf.d file, it will do so with no gps devices attached. Also note that if you are using a serial device it is still recommended to add the stty and setserial commands as noted in the example configuration above. Kismet is an 802.11 layer-2 wireless network detector, sniffer, and intrusion detection system. It will work with any wireless card that supports raw monitoring (rfmon) mode, and can sniff 802.11a/b/g/n traffic. It can use other programs to play audio alarms for network events, read out network summaries, or provide GPS coordinates.

That would also then remove a line from the gpsd.service file.2008 ski doo mxz 600 for sale
As an option we can install the gpsd-clients and python-gps packages which provide tools (e.g. gpscat, cgps, xgps) to test the communication with the GPS through the serial port as explained in the optional section 1.4.

There is another solution to provide the Raspi with an exact time. An additional module with a Real Time Clock. You can use this module alone or in addition to the GPS. This option is intended to be used with valgrind (1), gdb (1) and similar programs. The -g uses the monitor facility to run the gpsd instance within gpsfake under control of gdb. The -o specifies options to pass to the daemon.
