You can poll the SNMP port on the device by specifying the community name: The first DBINVENT instance listens on the default port TCP/1433, and the second MSSQLSERVER uses a fixed TCP/53200 port from the RPC range. = End of SQL Server query response =Īs you can see, the PortQry tool showed not only the availability of the 1434/UDP port but also the version of the SQL server and the names of the instances running on the SQL server and their TCP ports. Sending SQL Server query to UDP port 1434. PortQry.exe -n rome-sql01 -e 1434 -p UDP UDP port 1434 (ms-sql-m service): LISTENING or FILTERED Or you can check the availability and response from the SQL Server Browser service running on the Microsoft SQL Server: = End of RPC Endpoint Mapper query response = Portqry -n 10.0.25.6 -p tcp -e 135 TCP port 135 (epmap service): LISTENING In addition to checking port availability, the tool performs protocol-specific requests to obtain the status of services.įor example, using the following command you can check the availability of the RPC endpoint mapper service (TCP/135) and get the list of names of RPC endpoints registered on the computer (including their names, UUID, the address they are bounded to, and the application they are related to). These are LDAP, Remote Procedure Calls (RPC), e-mail protocols SMTP/POP3/IMAP4, SNMP, FTP/ TFTP, NetBIOS Name Service, L2TP, etc. PortQry has built-in support for some network services. Portqry.exe -local Advanced Network Services Open Ports Status in PortQry You can get information about opened ports and active TCP/UDP connections on the local computer:

Portqry -wport 3389 -wt 600 –l LogFile.txt -y -v Using the -wport and -wpid arguments, you can monitor the status of the specified port (wport), or all ports associated with the specified process (wpid) on the local host.įor example, the following command will monitor the response of the specified local port within 10 minutes (for example, RDP port 3389), and if its status changes, it will notify the administrator about this (a detailed log will be available in the LogFile.txt). The next command scans the ranges of the well-known TCP/IP port numbers and returns the list of ports that accept the connections (works as TCP Port Scanner): Using -o attribute, you can specify the sequence of ports to check their availability: In our example, the DNS server is available from the client both over TCP and UDP ports. By default, TCP ports are polled 3 times, and UDP is one. e., this port is not listening on the target system, or the access to it is restricted by a firewall or some system settings.
