LasetJet M4555 MFP: 221 ftp port and how to disable

We have a HP M4555 MFP printer that accepts ftp connections on port 221 anoymous and I can't figure out how to make it stop.  This raises red flags with our network security scanner, so would like to know how I can disable this feature.  We have all other than 9100 off printing protocols (including FTP printing), but this one printer always listens to the port 221.  Interestingly, we have 2 printers of the same model and only 1 done this and, as far as I know, they have identical configs.  However, whoever's doing this has rev firmware 3.7, and the one that is not is still the 3.5.1 then perhaps that it is a feature added to the new rev?

I can't say how much of a security problem is real, but it makes me very nervous that I can get in places like/Customer/Jobs/StoredJobs without any authentication at all.

Anyone have any ideas?

Thank you!

PS. Here is a demonstration of what I see:

Ftp $221 _HOSTNAME_

You can disable the port 221 using IPsec/firewall option tab 'network '.

Steps to follow:

Access IPsec/firewall. Set the default rule to "allow". Start creating a rule. Choose all the "IP address" for the policy address. In the event of service strategy page, choose Create a new service. Then create a personalized service.

For personal service, give a name like "port221". Select TCP. Choose ' printer/multifunction Service '. Choose a specific local port. Enter the port 221. Choose "Any" to remote port. A new service is created. Select it and click OK. You return to the page of service strategy. Click on the newly created service 'port221 '. Click "next". Choose the action "Drop." Click "next". Enable the IPsec/Firewall policy. When she returned to the home page, IPsec rules were created and activated.

Thank you.

    Hello

    If you are running XP SP3, in lieu of VISS, try Microsoft Security Essentials

    The Indexing Service indexes files to do research of the faster hard disk. Index of activity is expected to decline after a day or two (after that indexing is complete), and there should be no loss of performance.

  • FF 38.0.1: what's on: drive and how to disable?

    Just spent FF FF 38.0.1 37.0.2 and now on the right side of the location bar, there is a small icon on the page that opens the so-called topic: Reader. She only gives a very LARGE with large page for example Google, but for most of the pages it gives just an error message indicating that the loading of the page does not have. Very mysterious.

    I don't really know what this thing 'reader', as far as I know it looks like just another totally useless (and this time very mysterious) feature Add.

    And is not removable: when I use the normal way to adjust or remove icons and so on, the small icon of the page can not be or removed.

    Edit: just started using FF safe and then it's gone? Don't really know what it is then. It's something again today when I updated to FF 38.0.1. I don't have add on installed to a drive or something like that. See screenshot for the icon.

    Oh, well: it is caused by the LittleFox add-on and it will be fixed in the next update

  • What is BBThumbs.dat and when and why it created in the emulator and how to disable its creation?

    Hello

    I download a bunch of binary files from the server to a directory under "file:///SDCard/myfolder/".

    I notice that in the emulator sometimes BBThumbs.dat is created in this folder.

    Is there a way to disable the creation of this file.

    I use JDE4.3.0.

    I would appreciate any idea on it.

    -MO.

    the blackberry creates a thumbnail of each image in the file and stores it in this file when you open a folder.
    When you open the folder again the thumbnail can be recovered (if the hash matches) in the dat file rather created, it's much faster.
    Windows did the same thing btw.

  • Satellite Pro P - how to disable the hot keys for camera assistant?

    Is it possible, and how, to disable the shortcut keys for the camera wizard?

    The default keys interfere with shortcuts of Microsoft Office (Word) - for example Alt + F9 to show/hide codes field to turns on the properties of camera assistant, Alt + 10 screen settings of camera etc.

    I find this very frustrating.

    Hello

    Of course you can turn it off.
    You must remove the software from the camera in msconfig start up.

    So go to start-run-msconfig online online
    Go to the Startup tab and disable the camera software. Restart the computer laptop and that s all!
