Socket是指一个上面有很多“洞”的东西,比如说,计算机主机板上CPU的插座,我们称其为Socket 478或Socket 939等,而Socket上面这些洞在传输层中则称为Port,在OS的网络系统中会有两个Socket,分别为TCPSocket及UDP Socket,Socket上各有65536个洞,我们把它称为Port 0、Port 1、Port 2 …… Port 65 535。 我们以图...
int udpfd = socket( PF_INET, SOCK_DGRAM, 0 ); assert( udpfd >= 0 ); ret = bind( udpfd, ( struct sockaddr* )&address, sizeof( address ) );//UDP连接文件描写叙述符udpfd和address绑定了 assert( ret != -1 ); //同一个端口上绑定了两个不同类型(TCP和UDP)的socket文件描写叙述符 /...
There are basically two types of virtual ports, namelyTCPandUDP. TCP stands forTransmission Control Protocol; while UDP stands forUser Datagram Protocol. TCP and UDP ports use different network protocols when handling information traffic. Network protocols are nothing but the set of rules and ...
I have a service that listens on a port for both tcp and udp. I'd like to run something like docker run -p 8080 -p 8080/udp -i -t image_name and have docker use a same port on the host for tcp and udp. Where should I dig into if I want t...
Transport Control Protocol (TCP), User Datagram Protocol (UDP) ports, and Protocol Numbers are important to TCP/IP networking, intranets, and the Internet. Ports and protocol numbers provide access to a host computer. However, they also create a security hazard by allowing uninvited access. Ther...
Protocol: TCP/UDP Source zone: wan External port: [bind port] Destination zone: lan Internal IP address: 10.0.0.2 Internal port: 80 Others: keep default values {public-addr} {public-port} {ip4p} {private-port} {protocol} {private-addr} ...

PortQry 是一种命令行工具,可用于帮助排查 TCP/IP 连接问题。 此工具报告本地计算机或远程计算机上的目标 TCP 和用户数据报协议 (UDP) 端口的状态。 它还提供有关本地计算机的端口使用情况的详细信息。 由于PortQry 旨在用作故障排除工具,因此使用它来排查特定问题的用户应充分了解其计算环境。
To troubleshoot the TCP or UDP port: 1.SelectMaintenance > Troubleshooting > Tools > Commands. 2.Select the Portprobe command. 3.Select eitherTCPorUDP. 4.Enter the target server and port number. You can enter an IP address, hostname or FQDN for the target server. ...
