New Port Checks on the Port Scan Tool

If you haven’t noticed already we’ve beefed up the diagnostic capabilities of our Port Scanning Tool by adding 8 additional ports. We love making our lookup tools even more powerful and providing you with the information you need – fast.  Our updated port scan tool now checks a total of 25 ports to let you know what services are running on your server and open to the world. Here is a list of the new ports the tool now checks for open ports.

  • 111/tcp – Remote Procedure Call (RPC)
  • 135/tcp – Microsoft RPC for DHCP, DNS, and WINS
  • 445/tcp – Microsoft Active Directory and SMB file sharing
  • 1025/tcp – NFS, IIS or Teradata
  • 1723/tcp – Microsoft Point-to-Point Tunneling Protocol
  • 5060/tcp – Session Initiation Protocol
  • 5900/tcp – Remote Frame Buffer, VNC remote desktop protocols
  • 6001/tcp – X11 client-server network

So, why did we pick these ports?

At MxToolbox, we want to help you protect your organization.  We selected these ports because they rank high in statistical usage, provide high value services, and can be dangerous.  These ports, if exposed to the outside world, can be used to exploit your systems.  If you need them open, defend them.  If you don’t need them exposed, close them as soon as you can.  In short, if we can see them, then these services are exposed to the world and are at risk for hacks, DDOS attacks or data ransoms.  Remember to regularly patch systems supporting these services.  Keeping a close eye on these ports helps to protect your organization.

About the Port Scan Tool

This test will tell you what standard services are running on your server and open to the world.  You can type in an IP address or hostname.  We attempt a full TCP connection and graceful disconnect on each of about 25 common TCP ports we test, with a timeout of 3 seconds.   Possible results for each port are Success,Timeout or Refused.
