这篇文章给大家分享的是有关Xmanager如何连接linux 5配置的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
redhat as 5 用root 用户通过 xmanager 连接配置
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
......

tty3
tty4
tty5

tty9

添加这一些。
