分享xhost问题，unable to open display "192.163.3.153:0.0"
我在本机运行firefox，提示我：
Gtk-WARNING **:cannot open display。
于是我：
xhost +
结果提示我:xhost: unable to open display "192.168.3.153:0.0"
这是在livecd环境中的问题，在制作livecd的那台机器上都能正常运行。
请问这是什么原因，如何解决呢？

如果是在去sun的服务器上直接xhost +没问题，关键就是远程连接上去执行这个命令不行。
我也在等待答案

在出错的机器上将DISPLAY设置为:0试试。

有窗口显示了吗？登陆时是X界面吗？
如果确认，用strace xhost ....看看哪里出问题。

我也不知道啊，那软件包是livecdtools.tar.gz
我是按照http://knoppix.tnc.edu.tw/modules/news/article.php?storyid=195
这个网页上的步骤作的，本来想完全自己做一个，但是搞了好久，也没成功。
请问 fierygnu(va_list)， 你有什么好的自己从头做livecd方面的参考文献吗？
分不够我可以再开帖子阿

哈哈，好用啦，把/root/.Xauthority删除，logout，重新进入，然后就都ok了。
谢谢fierygnu(va_list)，不过我这个是livecd的环境，从新启动后，所有改变都恢复原样。
奇怪的是，我从启系统后，有光盘进入livecd环境，然后什么也没改，直接运行那几个软件，居然都好用了。
那上次怎么就不好用呢，怪。

是用root用户登录的吗？如果是，把/root/.Xauthority删除，logout，重新进入试试。

对了，我在livecd这台linux中，启动任何有图形界面的软件都不行，如openoffice,firefox,thunderbird等
而制作livecd的那台linux都可以正常运行这些软件的。

实际上是你的系统安全设置引起的。6000端口是X server的端口，被禁了。没有问题的系统用的是UNIX Socket连接，没有这个问题。
把DISPLAY设置为：
DISPLAY=unix:0，再试。按理说:0就是unix:0

你是说DISPLAY=192.168.3.153:0还是DISPLAY=:0
我都试了，还是不行啊，strace中的信息根上次基本一样，还是显示：
connect(3, {sa_family=AF_INET, sin_port=htons(6000), sin_addr=inet_addr("192.168.3.153")}, 16) = -1 ECONNREFUSED (Connection refused)
这是什么原因阿，为什么我做成livecd就不行了呢？

1、X Server启动了吗？
2、ifconfig看你的IP是多少？

我也遇到了这个问题，安装完db2之后管理控制台启动不了，然后设置DISPLAY参数为127.0.0.1:0.0.然后使用xhost +命令的时候出现和楼主相同的问题，请高手帮忙解决

x server启动了，在/etc/inittab中:
id:5:initdefault:
# Run xdm in runlevel 5
x:5:respawn:/etc/X11/prefdm -nodaemon
因为livecd用的是网上下载的软件制作的，不知为何我原来的设置不起作用（原来我是init 3），做好livecd后，又变成了id:5:initdefault:
-------------------------
ifconfig
inet addr:192.168.3.153
我用主机名，127.0.0.1，都不行。
