port 6379 # 绑定的主机地址 # 你可以绑定单一接口,如果没有绑定,所有接口都会监听到来的连接 # bind 127.0.0.1 # Specify the path for the unix socket that will be used to listen for # incoming connections. There is no default, so Redis will not listen # on a unix socket when not specified...
When using TCP, an application opens a connection (not to be confused with NetworkManager connections) between one port on its own machine and a port on a remote host. For example, an application such as a web browser could open a connection between port 36406 on its own machine and port ...
Now, although you still want to deny incoming TCP connections, you still need to make sure that your host can make TCP connections to the outside world. Because all TCP connections start with a SYN (connection request) packet, if you let all TCP packets through that aren’t SYN packets, ...

Checking the Ports on Linux Let’s now see how to check what port/ports a process is using on Linux. Here, we will show you the different commands for this purpose. 1. Lsof Command The lsof utility is helpful to obtain a list of the ports which are used by your system. Let’s con...
max connections :指定最大并发连接数以保护服务器,超过限制的连接请求将被告知随后再试。默认值为 0,即没有限制。 log file :指定日志文件 read only :设定是否允许客户上载文件。若为 true 任何上载请求均会失败,若为 false 且客户端拥有服务器目录读写权限则可以上载。默认值为 true 。
