netstat for android

As a whole, the output of Netstat can be divided into two parts: One is the active Internet connections, known as the active TCP connection, where "recv-q" and "Send-q" refer to%0a receive queues and send queues. These numbers should generally be 0. If not, it means that the package is piling up in the queue. This situation can only be seen in very few situations. The other is active UNIX domain sockets, known as the active UNIX domains socket (like

Linux is convenient, grep and then the WC will be fine. Windows has never been seen. The method for finding the count of links on Windows today.For example, to see the total number of current TCP links:NETSTAT-ANT|FIND/C/I "TCP"78If you want to see the number of 10.10.0.1 network links:NETSTAT-ANT|FIND/C/I "10.10.0.1"47What if you want to see all of the links? To use a magical string:netstat-ant|find/v/c/i "Matro"123"Matro" is your custom, as long as the string is not included in all links can b

Ping refers to end-to-end connectivity, which is often used as a check for usability, but some virus Trojans force a large number of remote ping commands to preempt your network resources, causing the system to slow down and slow down. Ping intrusion is strictly forbidden as a basic function of most firewalls to provide users with a choice.

Available under Windows, LinuxThe Netstat-ano command allows you to view the current usage of all ports on this computer. and arranged by the port number from small to large. If your native 3000 port has been called, it will also be listed, if not the proof is not used.Netstat-ano contains the PID number, through the task manager against the PID number, you can see which program called 3000 port.If you want to be more aware of how to check port usage

Use NetStat-r to query and analyze the route table to view the current system route table. The information provided in this table is: 1, and the LAN is 192. 168. 203 IP segment, your IP address is 128, and the gateway is set to 2. If the network you access is any network (0.0.0.0), you will exit from the gateway 192.168.203.2. 2. The internal Cyclic Network is the network segment specified as 127.0.0.0, and your internal address is 127.0.0.1. If you p

If you don't want to see so many connected states, and just want to see the number of concurrent connections, you can simplify the command, namely:Netstat-nat|grep established|wc-l1164The number returned is

cmd--return, enter netstat-ano--return, you can view the occupied port, note the PID of the port, and then open Task Manager, point to view, select columns, check the PID to determine, find the corresponding PID, end the process, if it does not end or does not work after the end, Just use the NTSD command.Tomcat Port Occupancy workaroundIf the front-end port is not occupied and is later occupied, you can go to the D:\tomcat-5.5.26\bin to execute shutd

ARP (Address Resolution Protocol)View the appropriate MAC address for the IP address.How to use: Arp-a IP Displays the current ARP cache table for all interfaces.Arp attack is to realize ARP spoofing by fake IP address and MAC address, can generate a large amount of ARP traffic in the network to block the network, the attacker can change the IP-MAC entry in the target host ARP cache as long as the persistent ARP response packet is issued, causing network int

It can be pinged, indicating that your TCP/IP protocol stack is okay! If there is a problem, you have to check the TCP/IP protocol stack or reinstall it! Your local IP address is used to check your network card. Check if your network card is working normally! (If you try to disable the NIC, you can find ping127.0.0.1, but ipconfig has no IP display,
