将 xubuntu 18.04 升级到 20.04 后 ----->没有 gpsd？没有 xgps！

我花了好几天的时间尝试让我的 GPSD 与非常灵敏的 Handy-GPS 一起工作。

通过 rfcomm0 从我的手持 GPS 获取 NMEA 数据没有问题。

gpsmon /dev/rfcomm0 works perfect

但是自从我从 18.04 升级到 20.04 后就没有机会处理 XGPS了。

 systemctl status gpsd.service

和

netstat -ptaun

我可以看到 GPSD 的标准端口 2947 被阻止了！？

不知道这句话是什么意思？？

 tcp        0      0 127.0.0.1:2947          0.0.0.0:*               LISTEN      1/init

启动我的 GPSD

sudo gpsd -n -N -G 2948 /dev/rfcomm0
gpsd:ERROR: can't bind to IPv4 port gpsd, Address already in use
gpsd:ERROR: maybe gpsd is already running!
gpsd:ERROR: can't bind to IPv6 port gpsd, Address already in use
gpsd:ERROR: maybe gpsd is already running!
gpsd:ERROR: command sockets creation failed, netlib errors -1, -1

我的问题：

1/init 代表什么？

我怎样才能绕过我的 GPSD 端口？

@heynnema

cat /etc/default/gpsd

# Devices gpsd should collect to at boot time.

# They need to be read/writeable, either by user gpsd or the group  
  dialout.
  DEVICES=""

# Other options you want to pass to gpsd
 GPSD_OPTIONS="-n -N -D4 "

答案1

您的 gpsd.service 已禁用。启用并启动它...

sudo systemctl enable gpsd.service

sudo systemctl start gpsd.service

sudo systemctl start gpsd.socket

sudo systemctl status gpsd*

更新＃1：

通过清除并重新安装 gpsd 将 /etc/default/gpsd 恢复为默认文件。

更新 #2：

您可能需要编辑 /etc/default/gpsd 并更改以下行...

START_DAEMON="真"

设备=“/ dev / rfcomm0”

更新 #3：

确保防火墙中的端口 2947 已打开。然后 xgps 和 cgps 应该可以正常工作。
