Sockets leaked in windows not shown in netstat and tcpview

Is it possible that windows leaks sockets connection and these sockets are not shown in tcpview and netstat? After running a few applications that perform many network connections, my windows machine enters a state in whitch it in not able to open any new socket connection. Even to itself (localhosts). For example, telnet to a local application failed because windows can't create new sockets. Closing and restarting the network applications does not helps. Only full windows restart solves the problem. netstat (& tcpview) indicates that there are only some dozens of connections. Thanks for your

问题 For example, in Android, the PID of a process 1234 is using ports 2222,2223,2224. Now I have a PID 1234. I was wondering how to find out port numbers 2222, 2223, 2224 which the process is using? I have tried using netstat -anp just as the way in Linux, but that didn't work. netstat -anp in ADB shell has the same effect as just netstat, which is without any command arguments. 回答1: You can either use busybox netstat -pt or cat /proc/1234/net/tcp 回答2: Try to check my github repository, https:/

问题 I only want mysql and status of 3306. I try these things but couldnt get output which i want. When I try netstat -anob | findstr 3306 information of mysql is not displayed. When I try netstat -anob | findstr sql information of port status is not displayed. as in snap shot you can see. I want whole information of process and port listening. I try netstat -anob it gives all the information. It means my parsing with finsdstr is wrong, please guide me in this. 来源： https://stackoverflow.com

问题 I have below netstat -ao result. Proto Local Address TCP 0.0.0.0:22 TCP 127.0.0.1:3306 TCP 165.120.144.11:139 TCP [::]:80 In this result what does IP 0.0.0.0, 127.0.0.1, 165.120.144.11 and [::] indicates ? 回答1: 0.0.0.0 is the wildcard address - which means your machine is listening on port 22 (SSH) on all interfaces/IP addresses that it can see. [::] is another way to represent this for IPv6. 127.0.0.1 is the loopback address - which means your machine is listening on port 3306 (MySQL) on

Check if TCP port is available (not listening or connected)

listing multicast sockets

问题 I am trying to list all opened multicast sockets on a linux system? netstat -g lists the groups joined though. Is there any other utility that I can use for this sake? Thanks a lot for the help. 回答1: In addition to netstat -g you can use this to see all sockets which are bound to a multicast address: netstat -anu|sort -nk4 This is a list of all UDP sockets (whether multicast or not). Look for all addresses in the range 224.0.0.0 to 239.255.255.255. These are sockets bound to multicast
