我安装了 FreeNX 服务器 (Ubuntu 10.04)，用户可以正常登录。当用户想要跟踪会话时，问题就出现了。它根本不起作用，尽管请求跟踪会话的用户会看到确认对话框（所以这是一个开始），但确认后就失败了。使用 NoMachine 版本不是一个选择，因为我们需要超过允许的最大数量，而不会付出荒谬的代价。
我已经验证了更改 AGENT_EXTRA_OPTIONS 时是否使用“-nolisten tcp”均无效。用户会话数限制为 5 个（因此 1 个用户 + 1 个影子不会违反此限制），并且总体会话数限制对于我们的目的来说足够高（目前只有这两个会话）。
如果有人有任何其他信息来解决这个问题，我们将不胜感激。

问题出在 freenx-team 的补丁 fix-getparam-url-decode.patch 中。虽然补丁本身没有问题，但它有一个副作用，就是它会导致 getparam() 返回第一个出现的参数设置，而原始代码最后返回。
这种差异对影子会话产生了一种肮脏的伎俩，nxnode 试图在与原始会话相同的显示器上启动影子会话。
肮脏的修复是编辑 /usr/lib/nx/nxnode:getparam 并将其恢复为原始状态：
getparam()
{
stringinstring "&$1=" "$CMDLINE" || return 1
echo "$CMDLINE" | tr "&" "\n" | egrep "^"$1"=" | awk -F= '{ VAL=$2 } END { print VAL }' | sed 's|%24|$|'
return 0
}
freenx 团队将知道如何在 Python 中正确修复此问题。
== fix-getparam-url-decode.patch ==
Add handling of '=' in the CMDLINE.
This was an issue when we were passing a command line for unix type of
gnome-session --session=2d-unity
The '=' was not getting decoded and gnome-session would die.

您是否尝试将 FreeNX 添加到现有显示器？我非常确定它不起作用。这里有一个解决方法，即在 VNC 中添加，但它在 SUSE 上。
