See how many bits and ports occupy the window System

Method One: Windows xp/server2003 is almost all 32-bit operating system 1.   Click Start, and then click Run.   2. In the Open box, type cmd (and then type systeminfo) or Winmsd.exe, and then click OK. 3. Locate "Processor" in the right pane below "project".   Note the value.   If "Processor" corresponds to a value that starts with "x86," the computer is running a 32-bit version of the Windows operating system. If "Processor" corresponds to a value that starts with "ia64," the computer is running a 64-bit version of the Windows operating system.

Method Two:

If the bit is installed, then, in My Computer properties, you can obviously see the logo. If the 64-bit is not indicated, then the default is 32-bit.

See how many Linux system bits:

command line input sudo file/bin/ls

Start--run--cmd Enter the command prompt input Netstat-ano you can see all the connected PID in the task Manager to find the program corresponding to this PID if the task Manager does not have the PID this item, you can select "View"-"Choose Column" in Task Manager

Often, when we start the application to find that the system needs the port to be occupied by other programs, how to know who owns the port we need, many people have a headache, the following is a very simple method, I hope to be useful for everyone

If we need to determine who's taking up our 9050 ports,

1. Windows platform
Execute under Windows command Line window:

C:>netstat-aon|findstr "9050"

TCP 127.0.0.1:9050 0.0.0.0:0 Listening 2016
Do you see that the port is occupied by a process number 2016 process, and continue with the following command:

C:>tasklist|findstr "2016"

Tor.exe 2016 Console 0 16,064 K It's clear that Tor is taking up your port.
