NOTE: See documentation for listen() socket call. TCP sockets in listening state are not shown - this is a limitation of NETSTAT. For additional information, please see the following article in the Microsoft Knowledge Base: 134404 NETSTAT.EXE Does Not Show TCP Listen Sockets FIN_WAIT_1 Indicates active close.

Running netstat -n to show the IP, I realized it was one of my own GCP servers - which made me wonder even more what was going on, thinking perhaps reverse DNS or even one of my DNS servers or something was configured incorrectly or something. Reverse DNS looked fine, although it should've clicked once I saw the reverse DNS.

netstat -o includes some timer information in the output but I haven't found an explanation of the output in the Timer column anywhere. Can anybody explain this or point to an explanation? This ist what the ouptput of netstat -o looks like (on Ubuntu 8.04).

2016年10月24日 · I'm trying to need to access/parse all outgoing connections on a particular port number on a Linux machine using a Python script. The simplest implementation seems to be to open a subprocess for netstat and parse its stdout. I imagine someone somewhere has had this problem before, and am surprised not to find any netstat parsers online.

The linux version of netstat uses a notation of <IP>:<port> where the IP address is displayed bare*. So :::111 means an IP of :: and a port of 111. :: is an IPv6 address in condensed form using the rule that a run of zeros can be replaced with ::.

2015年4月9日 · When you run netstat -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.

2012年8月18日 · For port 80, the command would be : netstat -an | find "80" For port n, the command would be : netstat -an | find "n" Here, netstat is the instruction to your machine -a : Displays all connections and listening ports -n : Displays all address and instructions in numerical format (This is required because output from -a can contain machine names)

Getting an output that shows a specific process or group of processes (listed as PIDs) in netstat -ano. The PIDs seem to be connecting to multiple 'Foreign Address' IPs, or perhaps trying to spam multiple foreign IPs. That's IF I'm interpreting the output correctly. Here's an example of the outputs in question.

2016年11月1日 · For example, to run netstat inside the container network namespace: $ sudo nsenter -t 15652 -n netstat Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN

Keep in mind that netstat will only show you active TCP or UDP connections, and while TCP and UDP are the most common protocols, there are a slew of others that exist that are potential attack avenues that netstat cannot show. Additionally, an attacker or malicious program could bypass all protocols and use there own custom connection protocol ...
