Port 22...can I close it?

vbimport

#1

I post here since I couldn’t find a “Network” section.

After a Internet port scanning, it appears that my port 22 is open. How can I close it?
I have a D-Link 504T Router.

Thanks.

Do a port scan using Gibson Research. If it finds a problem they usually offer a solution

Shields up is what your looking for, down the page a bit.

The other thing you could do right away is forward the port 22 to a fake address like 192.168.1.10. Then it talks to empty space.

Not sure what this has to do with CD/DVDs, but port 22 being open is an indicator that you are running some form of Secure Shell (SSH) server.

What OS are you using?

It should basically just be a matter of shutting down your SSH service for your OS. You could also always open up your router admin page and block incoming access to port 22.

Thanks. It was with the “Common Ports” test of Shields up that I’ve found out of the opened 22 port :slight_smile: .

I have to find out how to do this.

I have Windows Xp with SP2.

I have to find out how to do that too :slight_smile: .


#7

router user manual, OS has nothing to do with it :disagree:

:stuck_out_tongue: :slight_smile:

I tried this and the “Common Port” test reports that the 22 port it’s now in Stealth mode, but strangely the complete test Failed (even if the other port were closed or in stealth :confused: )


#10

Even the “All Service Ports” gave me a Failed!



#11

Then you got something still open in the first 1056 ports, 113 closed?

Don’t do commen, do all

Look previous post :wink: .

Strange.

your showing alot of closed ports, not stealth but dead to the rest of the world


#15

Goto “Control Panel==>Admin Tools=>Services”

Disable any service called “SSH” or “Remote Login”.

To close port 22 completely you will have to check in your router manual on how to close ports. It should be fairly straight forward.

By redirecting port 22 to a non-existant machine, you have effectively “stealthed” that port.

I am a little concerned at the huge number of stealthed ports being reported for your machine. You should only ever have a handful at most. I would immediately close down all unknown incoming ports on your router (unless you are running a server, shutdown everything), disconnect your PC from the net and run a full virus and spyware scan. After that, hook it back up and re-open ports on your router as you need them.

Also installing a personal firewall like Kerio or ZoneAlarm would be a good idea.

Yep that is an ugly scan :iagree:

Did I imagined the Huston phrase? I’m being six hours on the PC and I’m afraid I’m imagining things :stuck_out_tongue: .

Or a combination of the two :bigsmile: :bigsmile: .
P.S. I’m just kidding… :rolleyes:

Freaking strange!
I’ve stopped all the “useless” programs and look at the results…even more stealth ports :confused: :confused: .

Every night I scan my PC with Ad-Aware SE Professional and Spybot - Search & Destroy (both up to date).
