一、 XMANAGER 连接到 REDHAT AS 5 需要修改的地方。
rhel5 与 rhel4 不同的地方是， rhel5 裡没有 /etc/X11/gdm/ 这个目录， rhel5 的 gdm 的配置文件放在这裡 /usr/share/gdm/defaults.comf ，这一点可能是困扰大家的地方。
在 /usr/share/gdm/defaults.conf 裡确保有以下几句配置：
Enable=true
DisplaysPerHost=10
Port=177
在 /etc/inittab 裡把默认级别改為 5 ：
id:5:initdefault:
再在这个文件裡加一句：
x:5:respawn:/usr/bin/gdm
然 后重啟系统。然后在 windows 系统上运行 xmanager2 裡的 Xbrowser 程序，在裡面新建一个 Xmanager Session ，在 Host 这裡输入 ip 地址，其它配置都不要改变（包括端口号），确定退出。然后双击这个 New Xmanager Session ，看到登录界面：
二、 如果允许 Root 用户连接到 XMANAGER 需要修改以下内容：
# vi defaults.conf
[security]
# Allow root to login. It makes sense to turn this off for kiosk use, when
# you want to minimize the possibility of break in.
AllowRoot=true
# Allow login as root via XDMCP. This value will be overridden and set to
# false if the /etc/default/login file exists and contains
# "CONSOLE=/dev/login", and set to true if the /etc/default/login file exists
# and contains any other value or no value for CONSOLE.
AllowRemoteRoot=true
# This will allow remote timed login.
AllowRemoteAutoLogin=false
# 0 is the most restrictive, 1 allo
#vi /etc/securetty
