配置REDHAT的防火墙的IPTABLES。

# vi /etc/sysconfig/iptables

*filter

:INPUT ACCEPT [0:0]

:FORWARD ACCEPT [0:0]

:OUTPUT ACCEPT [0:0]

-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

-A INPUT -p icmp -j ACCEPT

-A INPUT -i lo -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT

-A INPUT-p udp --dport 177 -j ACCEPT  #这里若-i port 指定端口会引起开机自检问题

-A INPUT -j REJECT --reject-with icmp-host-prohibited

-A FORWARD -j REJECT --reject-with icmp-host-prohibited

COMMIT

重启IPTABLES

# service iptables restart

打开XDM

# xdm

查看XDM运行情况

# ps -ef | grep xdm

查看177端口下的应用

# lsof -i:177
