XManager連接Linux的設置
不同版本的linux所在的位置不一樣文件名也不一樣在red hat 4 裡面有三步
第一步找到/etc/inittab
把默認級別改為5
id：5：initdefault
第二步找到/etc/X11/gdm/gdm.conf
確保該文件中有以下幾句配置
Enable=true
DisplaysPerHost=10
Port=177
iptables -A INPUT -p udp -s 0/0 -d 0/0 --dport 177 -j ACCEPT（如果防火牆開啟，要加入177 端口過濾）
允許以root 用身份登陸：
[security]
DisallowTCP=yes
AllowRemoteRoot=true
第三步 後在終端輸入service iptables save
restart gdm using command
gdm-restart
or restart X11 using the command
init 3 && init 5
在red hat 5 裡面也有三步
第一步找到/etc/inittab
把默認級別改為5
id：5：initdefault：
第二步找到/usr/share/gdm/defaults.conf
確保該文件中有以下幾句配置
Enable=true
DisplaysPerHost=10
Port=177
iptables -A INPUT -p udp -s 0/0 -d 0/0 --dport 177 -j ACCEPT
第三步 後在終端輸入service iptables save
restart gdm using command
gdm-restart
or restart X11 using the command
init 3 && init 5
也可以用gdmsetup 圖形界面進行配置。
以下是其它一些操作系統的相關設置：
Red Hat and RHEL (Red hat 7, 8, 9 / RHEL 3, 4, 5)
1. Display manager configuration
? Change runlevel to 5
Open/etc/inittab and set the initial runlevel to 5 as following:
id:5:initdefault:
? Configure GDM
If you are using kdm, skip this section and go to 'Configure KDM' section below.
Open the following GDM configuration file and set the Enable entry to true in the [xdmcp] section:
/etc/X11/gdm/gdm.conf
(Red Hat 7, 8, 9, RHEL 3)
/etc/gdm/custom.conf
(RHEL 4, 5, 6, If the file does not exists, create one)
[xdmcp]
Enable=true
? Configure KDM
If you are using gdm, you can skip this step.
1. If you are using RHEL 4 or later release, skip this step. Otherwise, open /etc/X11/xdm/xdm-config and comment out the "requestPort" option as following:
DisplayManager.requestPort: 0
==>

2. Open /usr/share/config/kdm/Xaccess and remove the initial "#" character for the following line:
#* #any host can get a login window
==>
* #any host can get a login window
3. Open /usr/share/config/kdm/kdmrc and set the Enable entry to true in the [xdmcp] section as following.
[xdmcp]
Enable=true
2. Firewall (TCP/UDP Ports) Configuration

3. Reboot the remote host and start Xmanager
# init 3; init 5
CentOS (4, 5, 6)
1. Display manager configuration
? Change runlevel to 5
Open/etc/inittab and set the initial runlevel to 5 as following:

#* #any host can get a login window ==>
* #any host can get a login window
Then, find the [xdmcp] section in the /etc/kde/kdm/kdmrc file and set Enable to true like the following example:
[xdmcp]

and set Enable to 1 in the [xdmcp] section and DisallowTCP to false in the [security] section as following.
[xdmcp]
Enable=1
[security]
DisallowTCP=false
*Ubuntu 10.10 had a bug in its GDM (v 2.30.5) that only allowed IPv6 connections which caused Xmanager to fail connecting to the host. This bus was fixed in GDM version 2.32.0.
? Configure LightDM (Ubuntu 11.10 and 12.04)
If you are using Ubuntu 10.10 or previous releases, you can skip this part.
Create the /etc/lightdm/lightdm.conf file and save the following lines:
