Port query tool

Details on which you want to connect. In my below example, My Postgres database cluster is running locally on port 5432. You can add the remote server by giving the remote database cluster IP. Next, Enter the database username and password and click on the save.You can get more information about these fields on the below URL. ToolThe Query Tool is a powerful, feature-rich environment that allows you to execute SQL commands and review the results. You can access the Query Tool via the Query Tool menu option on the Tools menu, or through the context menu of select nodes of the Browser tree control. The Query Tool allows you to: Issue ad-hoc SQL queries. Execute arbitrary SQL commands. Edit the result set of a SELECT query if it is updatable. Displays current connection and transaction status as configured by the user. Save the data displayed in the output panel to a CSV file. Review the execution plan of a SQL statement in either a text, a graphical format or a table format (similar to View analytical information about a SQL statement.How to execute a query in pgAdmin 4Open the Query Tool Right-click on the database and click on Query Tool. In the snapshot below we are executing the SQL queries in the PostgreSQL database.After clicking on the Query Tool you will see the window below.Using the Query Tool environmentFor executing the query into the database, just write the query into the Query Editor and click on the Execute/Refresh (F5) button. It will execute the query into the database. For executing the query into the database you only need to write the query into the Query Editor and select it and after that execute it by using the Execute button. In the two snapshots below we are inserting and selecting the data from the table t1, which we created earlier.Creating functions, procedures, and triggers using Query ToolIn the below some examples we are creating the function, the procedure by using the query tool. The process is the same, we only need to write the code and execute it by using the Execute button.Create FunctionIn the example below we are creating the function add. Just place the code into the Query Editor and execute it.ExampleCREATE FUNCTION add(integer, integer) RETURNS integer AS 'select $1 + $2;' LANGUAGE SQL IMMUTABLE RETURNS NULL ON NULL INPUT;Create ProcedureIn the example below we are creating the

From a target UDP port, PortQry reports that the port is LISTENING or FILTERED. However, when you troubleshoot a connectivity problem, it's useful to know whether a port is being filtered or is listening. This is especially true in an environment that contains one or more firewalls.PortQry refines its port status report by using a second set of tests that can interact with the service or program that's listening on the target port. For this test, PortQry does the following:PortQry uses the Services file that's located in the %SYSTEMROOT%\System32\Drivers\Etc folder to determine which service listens on each port.PortQry creates a message that is specifically constructed for the expected service or program, and then sends that message to the target port. Depending on the service or program, the message may request information that's useful for troubleshooting, such as the following:Domain and domain controller information (LDAP queries)Registered client services and ports (RPC queries)Whether anonymous access is allowed (FTP queries)MAC address (NetBIOS queries)Mspclnt.ini file information (ISA Server queries)PortQry parses, formats, and then returns the response from the service or program as part of its test report.Additional tests to troubleshoot the local computerWhen you have to troubleshoot ports on the computer where you installed PortQry, use PortQry in local mode. When you use the local-mode parameters at the command line, you can do tasks such as the following on the local computer:Enumerate port mappingsMonitor a specific port for changesMonitor a specific process for changesFor more information, see Using PortQry in local (command-line) mode.Using PortQry in command-line modeYou can run PortQry at a command prompt in the same manner as any other command-line tool. Most of the examples in this article show command-line PortQry commands. In command-line mode, you can add multiple options to the command string to specify what query to run and how to run it. To run PortQry in command-line mode, run a command that uses the following syntax:portqry.exe -n [options]NoteIn this command, name_to_query> is the IP address, computer name, or domain to query. This parameter is required. [options] are the optional parameters.PortQry parameters for command-line modeThe following parameters are available in regular command-line mode:ParameterDescriptionComments-n Query the specific destinationThis is the only required parameter for command-line mode.The name> value represents the name or IP address of the computer to query. This value cannot include spaces.-p Use the specified protocolThe protocol> value represents the type of port to query (possible values are tcp,

Port 389)NetBIOS Adapter status query (UDP port 137)In these cases, PortQry uses an ephemeral port for the second test. When this occurs, PortQry records "Using ephemeral source port" in its output.If the computer where PortQry is installed also runs the IPSec policy agent, UDP port 500 may not be available to use as a source port. To temporarily turn off the IPSec policy agent so that you can use port 500, run net stop PolicyAgent. When you have finished testing, run net start PolicyAgent.-cn !!Query an SNMP communityThe community_name> value represents the name of the SNMP community to query. You must delimit this value by using exclamation points, as shown in the left column.If the SNMP service is not listening on the target port, PortQry ignores -cn.The default community name is public.-qRun PortQry in quiet modeWhen you use -q, PortQry suppresses all screen output except for error messages.To see output other than error messages, use -q together with -l. PortQry records the normal output in the log file.If a log file already exists and you use -q together with -l, PortQry overwrites the existing log file without prompting you.You cannot use -q together with -o, -r, or -p both.This parameter is especially helpful when you use a batch file to run a PortQry command string.Remarks for parameters in command-line modeAny port number value must be a valid port number between 1 and 65535, inclusive.The -e, -o, and -r parameters are mutually exclusive. A single PortQry command can use only one of these parameters.A query to UDP port 389 (LDAP) might not work against domain controllers that are running Windows Server 2008. To check the availability of the service that's running on UDP port 389, you can use Nltest instead of PortQry. For more information, see Nltest.When you query port 135 (RPC) by using -e or -o, PortQry returns all the endpoints that are currently registered with the RPC endpoint mapper.ImportantWhen you use the -r, PortQry doesn't query the RPC endpoint mapper.When you query port 53 (DNS), PortQry sends a DNS query for portqry.microsoft.com by using both TCP and UDP. If the server returns a response, PortQry determines that the port is LISTENING.NoteIt's not important whether the DNS server returns a positive or negative response. Any response indicates that the port is listening.Using PortQry in local (command-line) modeInstead of querying a port on a remote target computer, you can use PortQry
