最后,我们需要配置防火墙规则,以确保内外网之间的通信是安全的。在Linux中,可以使用iptables来配置防火墙规则。以下是一些常用的iptables命令: ``` sudo iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT sudo iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT ``` 上述命令将允许从eth0到eth1的数据流通,...
1. 使用防火墙:Linux系统自带了iptables防火墙,可以通过配置iptables来关闭指定的端口。首先打开终端,输入以下命令打开iptables配置文件: ``` sudo vi /etc/sysconfig/iptables ``` 然后在文件中添加以下规则: ``` -A INPUT -p tcp --dport 138 -j DROP -A INPUT -p udp --dport 138 -j DROP ``` 保存...

1. Stop the Firewall The first step when disabling Linux’s firewall is to stop the service. For most distributions, the firewall is managed by Systemd, meaning the systemctl command can be used. Depending on the Linux distribution, you can use either the iptables or fire...

Iptables is a Linux feature that examines the system’s security circle. As Linux users are comparatively fewer in number as compared to other operating systems, security will be enhanced. 30. Which command is used to check the number of files, disk space, and each user’s defined quota?
为什么会是防火墙呢?在iptables的一些NAT配置说明里有提到—— 4.3.6 State match 状态匹配扩展要有内核里的连接跟踪代码的协助,因为它是从连接跟踪机制中得到包的状态的。这样我们就可以了解连接所处的状态。它几乎适用于所有的协议,包括那些无状态的协议,如ICMP和UDP。针对每个连接都有一个缺省的超时值,如果连接的...
