How to find SQL Server running port?

Yes I read this How to find the port for MS SQL Server 2008?

no luck.

telnet 1433

returns connection failed, so I must specify other port.

I tried to use

netstat -abn

but I don't see sqlservr.exe or something similar on this list.

Why it so difficult to find that port? :/

Try this:

USE master
GO
xp_readerrorlog 0, 1, N'Server is listening on' 
GO

very simple. make a note of the sqlsrvr.exe PID from taskmanager then run this command:

netstat -ano | findstr *PID*

it will show TCP and UDP connections of your SQL server (including ports) standard is 1433 for TCP and 1434 for UDP

example :

This is the one that works for me:

SELECT DISTINCT 
    local_tcp_port 
FROM sys.dm_exec_connections 
WHERE local_tcp_port IS NOT NULL

If you can start the Sql Server Configuration Manager > SQL Server Network Configuration > Your instance > TCP/IP > Properties

If you have run "netstat -a -b -n" (from an elevated command prompt) and you don't see "sqlservr.exe" at all then either your SQL Server service is not running or its TCP/IP network library is disabled.

Run SQL Server Configuration Manager (Start | All Programs | Microsoft SQL Server 2008 | Configuration Tools).

Navigate to SQL Server Services. In the right-hand pane look for SQL Server (). Is it stopped? If so, start it.

Navigate to SQL Server Network Configuration (or SQL Server Network Configuration (32-bit) as appropriate) then Protocols for . In the right-hand pane look for "TCP/IP". Is it disabled? If so, enable it, then restart the SQL Server service.

Note that he Instance ID will be MSSQLSERVER for the default instance.

Please also note that you don't have to enable the TCP/IP network library to connect a client to the service. Clients can also connect through the Shared Memory network library (if the client is on the same machine) or the Named Pipes network library.

Maybe it's not using TCP/IP

Have a look at the SQL Server Configuration Manager to see what protocols it's using.

In our enterprise I don't have access to MSSQL Server, so I can'r access the system tables.

What works for me is:

capture the network traffic Wireshark (run as Administrator, select Network Interface),while opening connection to server.
Find the ip address with ping
filter with ip.dst == x.x.x.x

The port is shown in the column info in the format src.port -> dst.port

Try to enable the protocol by: Configuration Manger > SQL server Network Configuration > Protocols for MSSQLSERVER > properties of TCP/IP

This is another script that I use:

-- Find Database Port script by Jim Pierce  09/05/2018

USE [master]
GO

DECLARE @DynamicportNo NVARCHAR(10);
DECLARE @StaticportNo NVARCHAR(10);
DECLARE @ConnectionportNo INT;

-- Look at the port for the current connection
SELECT @ConnectionportNo = [local_tcp_port]
 FROM sys.dm_exec_connections
    WHERE session_id = @@spid;

-- Look for the port being used in the server's registry
EXEC xp_instance_regread @rootkey = 'HKEY_LOCAL_MACHINE'
                        ,@key =
                         'Software\Microsoft\Microsoft SQL Server\MSSQLServer\SuperSocketNetLib\Tcp\IpAll'
                        ,@value_name = 'TcpDynamicPorts'
                        ,@value = @DynamicportNo OUTPUT

EXEC xp_instance_regread @rootkey = 'HKEY_LOCAL_MACHINE'
                        ,@key =
                         'Software\Microsoft\Microsoft SQL Server\MSSQLServer\SuperSocketNetLib\Tcp\IpAll'
                        ,@value_name = 'TcpPort'
                        ,@value = @StaticportNo OUTPUT

SELECT [PortsUsedByThisConnection] = @ConnectionportNo
      ,[ServerStaticPortNumber] = @StaticportNo
      ,[ServerDynamicPortNumber] = @DynamicportNo
GO

SQL Server 2000 Programs | MS SQL Server | Client Network Utility | Select TCP_IP then Properties

SQL Server 2005 Programs | SQL Server | SQL Server Configuration Manager | Select Protocols for MSSQLSERVER or select Client Protocols and right click on TCP/IP

try once:-

USE master
DECLARE       @portNumber   NVARCHAR(10)
EXEC   xp_instance_regread
@rootkey    = 'HKEY_LOCAL_MACHINE',
@key        =
'Software\Microsoft\Microsoft SQL Server\MSSQLServer\SuperSocketNetLib\Tcp\IpAll',
@value_name = 'TcpDynamicPorts',
@value      = @portNumber OUTPUT
SELECT [Port Number] = @portNumber
GO

select * from sys.dm_tcp_listener_states

More there: https://docs.microsoft.com/en-us/sql/relational-databases/system-dynamic-management-views/sys-dm-tcp-listener-states-transact-sql?view=sql-server-2017

PowerShell with nice format and ability to distinguish between processes:

ForEach ($SQL_Proc in Get-Process | Select-Object -Property ProcessName, Id | Where-Object {$_.ProcessName -like "*SQL*"})
{
    Get-NetTCPConnection | `
     Where-Object {$_.OwningProcess -eq $SQL_Proc.id} | `
      Select-Object -Property `
                                @{Label ="Process_Name";e={$SQL_Proc.ProcessName}}, `
                                @{Label ="Local_Address";e={$_.LocalAddress + ":" + $_.LocalPort }},  `
                                @{Label ="Remote_Address";e={$_.RemoteAddress + ":" + $_.RemotePort}}, State | `
      Format-Table
}

Default output:

Here is a quick PowerShell script (since no one has provided solution in PowerShell yet:))

Note: this must be executed at Server (either RDP or use PS Remoting), if ran correctly following will print exact port number:

cls
$id = (ps "sql*" | ? {$_.ProcessName -eq "sqlservr"}).Id
$id | % {
    $strAllSQLConnections = netstat -ano | findstr $_
    $port = $strAllSQLConnections | % { if($_ -match "0\.0\.0\.0:\d{2,5}") {$Matches[0]} }
    $port = ($port -split ':')[1]
    if ($port -gt 0) {Write-Host "An instance of Sql Server is listening on port: " $port}
}

You might need to tweak the code, works great for me.
