Yatse XMBC 远程自动启动

我有一个脚本，它在端口 12 上监听，并在收到 wol 数据包时调用 xbmc。当我直接从命令行启动脚本时，它运行良好，但当我让 upstart 运行它时什么也没发生，甚至没有写入日志文件。有什么想法吗？

编辑：在线程末尾添加日志

以下是 xbmc 脚本，但遵循了 upstart 脚本：

#!/bin/bash

UDP_PORT=12            # Change this if you need to run this on a different port, just remember to update Yatse's settings as well
RUN_XBMC_AS=usrname     # Change this if you need to run it as another user

LOG_FILE="${HOME}/xbmc-autostarter.log"

START_PHRASE="YatseStart-Xbmc"    # Do not touch this, unless you know what you are doing...

# The following block checks if the user running this script has the required privileges to listen on the port specified above
   WHO=`whoami` 
   if [ "$WHO" != "root" ]; then
      echo "Unprivileged users may not evesdrop on ports. Cannot start unless running as root."  &>> "${LOG_FILE}"
      exit 1
   fi

echo "Listening on port $UDP_PORT for Yatse remote start command"  &>> "${LOG_FILE}"

while [ true ]; do
   # Wait for a packet to come in from Yatse
   LISTEN=`tcpdump "udp port $UDP_PORT" -A -c 1 -i wlan0 2>&1 | grep -o "$START_PHRASE"`
   echo ${LISTEN}  &>> "${LOG_FILE}"
   # Make sure that we received the right command
   if [ "$LISTEN" = "$START_PHRASE" ]; then
      #echo "Starting XBMC as $RUN_XBMC_AS" 
      # Start XBMC using sudo -u to run it using the username above
      # If you need to you can replace the xbmc command below with xbmc-standalone if you are not using a window manager
      sudo --user=$RUN_XBMC_AS xbmc  &>> "${LOG_FILE}"
   fi 
   # Sleep, to be nice, for unwanted rogue processes writing to our port
   sleep 1
done

我认为您需要在脚本中导出用户的显示，以便它知道要使用哪个显示。通常，第一个 X 用户的默认显示设置为:0。

尝试添加export DISPLAY=:0到脚本的顶部：

UDP_PORT=12            # Change this if you need to run this on a different port, just remember to update Yatse's settings as well
RUN_XBMC_AS=usrname     # Change this if you need to run it as another user
export DISPLAY=:0
