Failed authentication, ARD 3.8, Terminal solution does not work

Hello

I'm on an iMac running OS 10.11.3, using 3.8 ARD to administer the computer of my children, which also runs OS 10.11.3.

I have the remote administration and remote login enabled on the computer of those of children, and ARD has worked very well for about a week. But suddenly today, I get the error "Authentication failed" when I try to access the other computer. Double checked the system settings, but all distance options are always checked "on".

I found this article with instructions on how to use the Terminal to fix the problem, but it's not helping:

Re: How do you define the computer so that you can see with Remote Desktop?

I pasted the second chain of command 'sudo' in the article, its replacement by the? with ssh address for computer of those children. But I just get a "command not found".

Any advice?

I'm guessing that your portion of the IPS via DHCP.

If that's true, my first guest would be that the IP address has changed.

If you run the scanner, see if it displays the IP address of the computer you are trying to connect to. If it is empty, the IP address has changed and no longer 'find '.

You can try to search using 'Hello' and try to connect and it will resolve to the new IP address.

If this does not work, see if a new account has been created, or if the user name has changed on the workstation.

Keep me posted and we can get it is resolved. those are the most common causes of the error you described.

  • no solution does not work when you try to download itunes 10, I'm at my wits end. What can we do?

    I have everything all except unistall Windows Vista, is there something else I can do?

    You could try and uninstall all references to iTunes on your computer.

    Use the control panel to uninstall iTunes and software components in the following order:

    1. iTunes
    2. QuickTime
    3. Apple Software Update
    4. Apple Mobile Device Support
    5. Hello
    6. Application of Apple Support (iTunes 9 or later)

      Then a few solutions that worked is to install and erarlier version of iTunes as there have been some problems with version 10.

      If you work with Microsoft supports a call, it would be better to continue with this support.

      Otherwise, I would contact Apple for support of iTunes.

  • Menu "Edit in Photoshop" Lightroom is gray - Adobe solution does not work.

    I have a problem with not being able to edit in PS directly from LR, because the Photoshop options in the menu lists "change in" are grayed out. I have other software installation (e.g., Macphun) and those are all listed and behave normally in LR.

    I have run that the latest versions of LR and PS through CC and all are updated. They move on a Macbook Pro I've had for 2 years and OS 10.11.5. I have not installed other software recently.

    I have not moved any of my files, which are mostly dng conversions (NEX7) Sony raw files and some old cr2s Canon. They are original, that is to say, not overviews etc.. The greyed out behavior occurs with all types of files I have in LR (including JPEG files).

    PS options are grayed out if PS is running or not.

    I followed all the steps Adobe ("Edit in Photoshop" missing order), UN and re installed both programs, all to nothing done.

    I have reset the preferences in LR and Psalm

    And, finally, I just this minute and re installed PS United Nations (just to double double check) and who did not make a difference.

    I tried to find solutions and read through these forums so apologies if I'm missing something blinding (which wouldn't surprise my wife in the slightest).

    Any suggestions about how to fix it are welcome.

    FYI - this has been resolved by installing Mac OS Sierra.  I already deleted all the files Adobe and records (including the hidden), installed the OS, then CC, Ps, then Lr.  Works as it should now

    However, empty the file provided by Adobe as a solution is a text file. Is this a mistake? I followed the instructions but it did not fix the problem. I guess the provided text file must contain data.

  • Wireless does not work on Qosmio f60-159

    I have a problem on a Qosmio f60-159.

    In "improving the performance of the computer", a message saying that some services that * ing the computer appeared and asked me if I wanted to turn this service off.
    I said yes and after that the wireless feature no longer works.

    The indicator in the front panel wireless is always on, no matter if I press this led or not.
    In addition, toggling the fn + f8 key does nothing.
    The diagnosis told me to turn on the radio, but if there is no switch in addition to these two, this solution does not work.

    I have cleaned the registry, reinstalled the wireless driver and when I try the same thing with bluetooth it says for the driver installation procedure I should turn on the wireless.

    What can I do?

    Hello

    It appears that you have disabled a service that controls the FN key or Wlan functionality. I think that the WiFi network is disabled and therefore it of not possible to establish the connection

    I think you should check this:
    Select all programs-> Toshiba-> Flash memory card Support utility, and then restart Flash cards.

    Flash cards control the FN keys and so I think that might help.

    Also I recommend that you check the Services tab, which is located in the Manager (CTRL + ALT + DELE) tasks

    Recommend to check and allowing (if disabled) the following process:
    Wlansvc (Wlan auto configuration)

    Good luck

  • How do Dungeon Siege (game) still does not work?

    I found this discussion (link below), but as many people (including some noted it here), this solution DOES NOT WORK for me.  I get "Exception caught Gathering exception data [this can take several minutes]" as the error with a black screen.  And I could wait 3 hours and still nothing happen.  I receive as messages "this program is not compatible", which indicates that she has not been fixed or patched in any measure.  I use the "Xplosive" 3 CD pack published by guess who?  Microsoft.   It seems suspicious that many games Windows XP works fine, but those published by Microsoft does not work.  Isn't a little backwards?

    You can do all sorts of apologist excuses like "it is an old game and no one cares", but if nobody cares, so why people keep posting questions here and anywhere online?  I think you're all just try to shut us up.  And why... for what?  You may think that I'm just a cheapskate.  I'm not just be cheap, I enjoy this game and want to play again.  It's like a song.  If you insist that I ever listen to 'Sail Away' of Styx again just because it is old?  I bought it is game with a lot of money in good faith and I expect to work.  Really, it will cost you a whopping hours of your development time for a post patch.  I have no pity for you and Yes, you can bill me (better yet, when you come out with a new version of windows, just me to pay for a "maint game package" which covers your expenses, as I said, I'm not cheap, I like just the old games).

    If you decide to publish something, then you have a responsibility.  But giving someone something and then taking it are a sure way to frustrate and annoy your users and make people angry. That's why I have no shame to be really angry and frustrated, it's how I feel in this situation.  Only one unreasonable and illogical would be satisfied with this.

    That said, if someone has a different suggestion outside (because it does not work for me on Windows 7 and is not enough anyway because he keeps the messages "this game is not compatible")... Please respond and make the suggestion...

    As noted, the above link leads to a '' correction '' that does not work for me or another poster in this thread.  As well, "compatible" message did not go for anyone no matter what you do.  Actually, I have a Windows 95 laptop I keep for all of these emergencies.  It is ridiculous to have to use it for this purpose but it seems that Microsoft prefers I should do instead of using Windows 7 or something more modern.  Ok then.

  • HP Photosmart Premium C309g-m: HP Solution Center does not work

    Improved win7 to Win10 House and it worked all fine until a few weeks ago.  Now when I open the HP Solution Center, the drive vibrates for a while, I see HPqdirec.exe (32 bit) process for a second in the Task Manager (not all the time but that could be just instant calendar), the Bell PC bumps (each time) but the window does not open.  There is no error message, no even if I run it from a command prompt window.

    I tried to uninstall the HP printing software (originally installed in Win7) - he asked me to restart the PC to continue the uninstall - but then he pointed out a mistake and said: he has failed.  Now when I try to uninstall it, it has no installed components.  I have correctly installed the latest PS_AIO_06_C309g-m_140_408 - 5.exe and the printer works but not the center of the Solution.

    The only recent software change that comes to mind is that I went free Avast antivirus with AVG free.  Do not know if the symptoms coincide with this change.  Disable AVG has no effect.

    I have a laptop Alienware M17x R2 that was running Windows 7 Ultimate SP1. Recently, the hard drive crashed. I replaced the hard drive and reinstalled the operating system using my recovery disks.

  • 802. 1 x authentication aid does not work

    According to the CEC documents, the following command should be a switch to do authentication for 802. 1 x for users. If this fails, the switch must fall back to no authentication. This prevents users to be locked to the network if the AAA/RADIUS server goes down.

    radius of group AAA dot1x default authentication no

    However, this command does not, at least not on the Catalyst IOS switches. If you disable the RADIUS server, the switch continues to try to use RADIUS regardless of the command above, even if the debugging indicates that the RADIUS server is dead.

    This directly conflicted with the following doc:

    http://www.Cisco.com/en/us/customer/products/hw/switches/ps646/products_command_reference_chapter09186a00801cdf12.html#1995856

    It is quite wrong that anyone who put implement 802. 1 x will be locked out of their network if the RADIUS server fails.

    Wireless access points do not have this problem because they can use a local RADIUS server. But it's a big problem for anyone with 802. 1 x running on cable networks.

    When Cisco will be be to fix this problem?

    Thank you.

    PAUL G.

    This does not work for 802.1 x and Catalyst switches.

    We will fix the documentation.

    In addition, Wireless APs don't have this problem with JUMP.

    Therefore, the challenge with Wired.

    Many EAP types, many types of back-end databases, etc. all need to review.

    We will have a configurable button in the near future to address, but as always, redundancy is recommended.

  • HP Solution Center not working after reboot (scan fails also)

    My HP Photosmart 3310 software fails after a reboot, the day or the installation of the printer in Windows 7 64 bit.  No error - it is said that installation is not completed and to connect the USB cable (it worked only 1 hour ago), or the printer is offline.  I can reach the printer via IP (192.168.1.64 - static IP).  The other computers in the House are printing and scanning very well.

    Help I received via the software discussion and support forums is to re - install the software.  I did it more than 20 times - it does NOT work. Let me repeat if you have not received this the first time - software does NOT solve the problem.

    The scanner and the printer work fine after that the software is completely installed.  The problem is that the printer and the scanner work not the next day.

    Yes, I tried:

    1. check the latest system and windows updates.

    2. turned and on the firewall.

    3. pull on the printer and connect via a USB cable.  "" The installation is complete, but I can't run this way. The problem comes back the next day when I tried using the printer as a network through the router.

    4 when I "add" the printer to Windows printers list, it causes the software HP Solution Center to enter the "incomplete installation error.  Then, either the scanner or printer works, not both at the same time.  Other computers work fine.

    5. it's a brand new computer, if any old malware running.

    6. I uninstalled, reinstalled, installed multiple copies, etc. of the latest version of the software from this site (AIO_CDB_FSW_Full_Win_WW_130_141) printer.

    7. I ran the software patch network of HP, before and after the reboot, no real effect.  (CPE_SLP_NETWORKMSI_hpcom_000_006)

    Any help would be greatly appreciated.

    I found a solution to the issue of scanner!  I installed the software VueScan from http://www.hamrick.com/ , the software is designed for high end photo editing, so it's a no-brainer for her to scan documents.  The free version works fine. If I wanted to the cost of the professional version of the $90 is nothing compared to the time I've wasted on getting the HP software to work.

    To resolve the problem of the printer, I installed the driver through windows and bypassed the HP software.  The only thing that miss me is now the ability to fax, but which can be performed directly from the HP Photosmart camera.
