Aug 11, 2019 · 10.86.128.138 is the IP address to which sshd application bind to (LISTEN) 22 is the TCP port that is being used (LISTEN) 85379 is the process ID of the sshd process; Option #2: netstat command. You can check the listening ports and applications with netstat as follows. Linux netstat syntax Netstat, a part of net-tools package, despite being considered a deprecated Linux networking command, is still widely used on many systems (RHEL 6.5, Debian 7, Ubuntu 12.04, Ubuntu 14.04). Netstat can print network connections, routing tables. using the 'Find' command allows you to filter the results. find /i "listening" will display only ports that are 'Listening'. Note, you need the /i to ignore case, otherwise you would type find "LISTENING". | find "port" will limit the results to only those containing the specific port number. To sum it up, a listening port is one that is waiting for a connection. An established port is one that is connected to a remote computer. As for what common ports that would be open on XP Home Apr 24, 2017 · Now let’s look at what’s listening on port 443, and just display the process responsible, the local port, the state, and the remote address Just like most other get cmdlets, this information can easily be output to a file in a nice format. 리눅스 서버 LISTEN 중인 포트 확인 netstat, nmap 995 closed ports PORT STATE SERVICE 22/tcp open ssh 80/tcp open http 3306/tcp open mysql 3690/tcp

Displays active TCP connections, ports on which the computer is listening, Ethernet statistics, the IP routing table, IPv4 statistics (for the IP, ICMP, TCP, and UDP protocols), and IPv6 statistics (for the IPv6, ICMPv6, TCP over IPv6, and UDP over IPv6 protocols). Used without parameters, netstat displays active TCP connections. -a: Displays all connections and listening ports.-b: Displays the executable involved in creating each connection or listening port. In some cases, well-known executables host multiple independent components, and in these cases, the sequence of components involved in creating the connection or listening port is displayed. The Listening Ports section of the Network tab gives you information about the services and processes on your system that are waiting to service network requests. These services are listening on either a TCP or a User Datagram Protocol (udp) port. This section shows process name, process ID, listening address, port, protocol, and firewall status.
May 18, 2020 · This switch displays active TCP connections, TCP connections with the listening state, as well as UDP ports that are being listened to. -b This netstat switch is very similar to the -o switch listed below, but instead of displaying the PID, will display the process's actual file name.
Netstat is used to display active TCP connections and related listening ports in the computer or system. Actually, there are more features provided by netstat like display statistics about network stack protocols, IPv4, IPv6, TCP, UDP, etc.
