RedHat Enterprise Linux 6.4 configure Xmanager 4

Perform the following operations as an administrator:

1. vi/etc/inittab

Id: 5: initdefault: // set the system runtime level to 5. If it is 5, no modification is required.

Id: 5: respawn:/usr/sbin/MCM // Add to the last row

 

2. Restart X11.

Init 3

Init 5

 

3. vi/etc/TPD/custom. conf

# Gestation configuration storage

[Daemon]

[Security]

[Xdmcp]

Enable = 1

[Greeter]

[Chooser]

[Debug]

 

Add a red row at the corresponding location and then save it with/wq. Restart.

 

Client (Windows): (Note: Sometimes the Windows Firewall blocks Xmanager and releases it when prompted)

Install Xmanager 4 on the client and open Xbrowser. You can enter the ip address in the ADDRESS column, for example, 192.168.10.212.

 

If the firewall is enabled, run the following command to open port 177:

Iptables-a input-p udp -- dport 177-j ACCEPT

 

Vi/etc/sysconfig/iptables

 

-A input-m state -- state NEW-m tcp-p tcp -- dport 177-j ACCEPT

-A input-m state -- state NEW-m udp-p udp -- dport 177-j ACCEPT

 

/Etc/init. d/iptables restart

Vi/etc/sysconfig/iptables

-A input-m state-state NEW-m tcp-p tcp-dport 80-j ACCEPT (allow port 80 to pass the firewall)

-A input-m state-state NEW-m tcp-p tcp-dport 3306-j ACCEPT (allow port 3306 to pass the firewall)

Note: many users add these two rules to the last line of the firewall configuration, which causes firewall startup failure. The correct rule should be added to the default port 22.

The firewall rules are as follows:
