Windows snmp query tool

I was just thinking if we buy a product the support will be top notch - Surendra, Team Lead, Cisco Systems. I have been working with the package for a couple of weeks now and it looks very good. I am using it to test a real time frequency and time agent for snmp v1, v2 and v3 and it's looking good. Simple yet effective tool for a small medium organisation where very few IT users are manning more than a server. It's not important whether the DNS server returns a positive or negative response.

Any response indicates that the port is listening. Instead of querying a port on a remote target computer, you can use PortQry in local mode to get detailed information about the TCP ports and the UDP ports on the local computer where PortQry runs. Use the following syntax to run PortQry in local mode:. When you troubleshoot connectivity issues between computers, you might have to type many repetitive commands. Such actions might be done more easily by using PortQry in interactive mode.

To start PortQry in interactive mode, use the -i parameter. For example, run the following command:. You can use the following shortcuts together with the query command to run common queries without having to set port and protocol options.

Use the following syntax:. If you omit the shortcut, the q command queries TCP port For example, entering q dns in interactive mode is equivalent to running portqry -n You can use the set command to set options such as the source port or slow link delay. Suppose you want to query a computer that has the IP address At the interactive mode command prompt, enter n This command produces output that resembles the following excerpt:.

To send a DNS query, enter q dns at the interactive mode command prompt. PortQry uses this file to resolve port numbers to their corresponding service names. PortQry uses this information to select the format for its queries. You can edit this file to direct PortQry to send formatted messages to an alternative port.

For example, the following entry appears in a typical Services file:. You can edit this port entry or add an additional entry. When you run PortQry in local mode, as in the previous example, you might see output that resembles the following excerpt. Such output indicates that the security context that PortQry is using doesn't have sufficient permissions to access all of the information that it requested. The following command queries the default UDP port on a computer that's specified by using its computer name:.

The following command runs the same query as the previous command but skips the name resolution step:. The following command queries UDP ports , , and in that sequence on the computer "myServer":. The following command queries the range of ports from port to port inclusive on the computer "myServer":. The following command queries TCP port on mail. If the file already exists, PortQry overwrites it without prompting for confirmation.

The following command queries TCP ports , , and 25 on mail. I even tried to regsvr32 that dll, but I was unsuccessful. Windows does not come with a default SNMP client, so you would have to install software. Sign up to join this community. The best answers are voted up and rise to the top.
