netstat with process name?

Question

Using netstat -a -o -n I can get the list of ports and PID

then I need to go to task manager and add the PID and see who is it. (pretty frustrating)

I was wonder if there is a CMD command which does it all ( using find , for , powershell)

so that I could get the process name

Answer 1

Solution

Use the -b parameter:

  -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. In this case the executable
                name is in [] at the bottom, on top is the component it called,
                and so forth until TCP/IP was reached. Note that this option
                can be time-consuming and will fail unless you have sufficient
                permissions.

Note The netstat -b command will fail unless run from an elevated command prompt.

Workaround

Filter the process list and find the PID you're interested in:

tasklist | findstr /c:"PID"

Alternate solution

You can use Tcpvcon.exe instead. No admin rights required.

Tcpvcon usage is similar to that of the built-in Windows netstat utility.

Usage: tcpvcon [-a] [-c] [-n] [process name or PID]

 -a Show all endpoints (default is to show established TCP connections).
 -c Print output as CSV.
 -n Don't resolve addresses.

I think you are looking for TCPView from SysInternals.

If you're fond of using PS, you can fork this code (note: it's super-basic)

$nets = netstat -ano | select-string LISTENING
foreach($n in $nets){
    # make split easier PLUS make it a string instead of a match object:
    $p = $n -replace ' +',' '
    # make it an array:
    $nar = $p.Split(' ')
    # pick last item:
    $pname = $(Get-Process -id $nar[-1]).ProcessName
    $ppath = $(Get-Process -id $nar[-1]).Path
    # print the modified line with processname instead of PID:
    $n -replace "$($nar[-1])","$($ppath) $($pname)"
}

Note that you can try Path instead of ProcessName to get a full executable path - it won't work with system services though. Also, you may want to append the ProcessName to the end of the line instead of replacing the PID value.

Enjoy it ;)

Here is an example for windows using FOR to parse netstat output then DO tasklist with /fi filter on pid to show process name.

The last find is to remove tasklist headers.

FOR /F "usebackq tokens=5 delims= " %i IN (`netstat -ano ^|find "443"`) DO @tasklist /fi "pid eq %i" | find "%i"

prints records output like

tomcat8.exe.x64               4240 Services                   0    931,864 K

Additional fields from netstat can be added by adding tokens.

Answer 5

Try to use this...

Process name with time stamp :) in oneliner... no need scripting fast and easy ...

You can change param SYN_SENT by ESTABLISHED or LISTENING

filter timestamp {"$(Get-Date -Format G): $_"};netstat -abno 1 | Select-String -Context 0,1 -Pattern LISTENING|timestamp

filter timestamp {"$(Get-Date -Format G): $_"};netstat -abno 1 | Select-String -Context 0,1 -Pattern SYN_SENT|timestamp

Very nice Erik Bitemo! I was thinking of adding a variable for the path then I realized you already have that although it was not defined. So the code I reused was:

$nets = netstat -ano |select-string LISTENING;
foreach ($n in $nets)
    {
# make split easier PLUS make it a string instead of a match object
    $p = $n -replace ' +',' ';
# make it an array
    $nar = $p.Split(' ')
# pick last item...
    $pname = $(Get-Process -id $nar[-1]).ProcessName
    $ppath = $(Get-Process -id $nar[-1]).Path;
# print the modified line with processname instead of PID
    $n -replace "$($nar[-1])","$($ppath) $($pname)" | where {$pname -like "*GMSVP*"}
     }

I was trying to find the processes and services for an application where I used a somewhat different 2 liner.

Get-Service | select status,name,displayname,servicename | where {($_.DisplayName -like "myserv*") -or ($_.servicename -like "post*")} | ft -auto

Get-Process | select id, processname,cpu,path,description | where {$_.path -like "*myserv*"} | ft -auto
