通过Xmanager远程连接RedHat Linux AS 5

rhel5与rhel4不同的地方是,rhel5里没有/etc/X11/gdm/这个目录,rhel5的gdm的配置文件放在这里/usr/share/gdm/defaults.conf。

需要修改的地方如下:

修改/usr/share/gdm/defaults.conf文件,确保里面有以下几行:

Enable=true

DisplaysPerHost=10

Port=177

再修改/etc/inittab文件,把默认级别改为5,再加入以下行:

x:5:respawn:/usr/sbin/gdm

这样修改后,root用户还不能登录,还要继续修改/usr/share/gdm/defaults.conf文件,具体如下(红色部分):

[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

如果防火墙打开了,使用以下命令打开177端口:

iptables -A INPUT -p udp --dport 177 -j ACCEPT

用gdm-binary -daemon 启动, 177端口
