Back to My Mac / Remote Management / Screen Sharing

I'm managing computers for my family spread across 3 states. I would love to get screen sharing working but it's just not happening. I've tried the steps in the following KB article and that's allowed me to access two mini servers (one 10.7 and one 10.6.8) at home. However, I can't access a MBP at home and I can't access my family's computers (via screen sharing) at all. Here's the KB article...
http://support.apple.com/kb/HT3486
Here's all I'm seeing (5 computers are "missing")
I've tried NAT port forwarding (Airport Extreme/Time Capsule) for "Apple Remote Desktop" to the computers internal IPs on ports 5900 & 3283. I've tried it without. I've tried both "Screen Sharing" and "Remote Management" in preferences. I've made sure I have my own account with admin privledges on all machines etc. This is, of course, all peppered with the occasionaly outburst of foul language...
What am I missing?

Spoke with Apple who spoke with Apple and so on. Tech support for Apple Desktop Remote acknowledges (as best they could) that there is a bug/ problem. Yes, reverting to an older (3.5 - 3.4 ARDagent) solves the problem (short term ?). They captured my OS info and will get back to me in 3-5 days - how do you like them apples! So, revert to ARDagent 3.4 and you can remote connect - may try this later... will post if it works. Here's what's been posted on this: https://discussions.apple.com/thread/3192451?start=0&tstart=0

Back To My Mac multiple display screen sharing issue

Since upgrading to Yosemite, I've been unable to access one of my screens remotely via Screen Sharing and BTMM. It only shows the screen attached to the HDMI interface, it's as if the other display doesn't exist. There is no option to select the other display in the Screen Sharing View menu. In Mavericks it would by default show both screens and I could select one. I've tried disabling and re-enabling the Sharing function on the host Mac. The screen that it does share works perfectly, so it seems to just be a problem of recognizing the other display.
Host is a 2012 Mac Mini, client machine a MBP, both running 10.10.1.

Remote connection, screen sharing, etc question

I'd like to remotely connect to my desktop either from a PC or another mac that isn't on my local network. I have a domain name registers, and i'd like to use this domain (godaddy.com) and just be able to type afp/smb/ssh (depending on if I'm on a mac or pc) and hhtp://www.mydomian.com and instantly get to my computer to change downloads and get files from an external drive, my OSX main disk, etc. I have a MobileMe account to, if thats any help. if I cant use my domain and somehow point it to my dynamic IP, I can use dyndns.
thanks

how would I set this up? do I forward 5900 (is that the ssh port?) and 22 on my router? or after that type ssh www.mydomain.com:5900? I'm not sure how to enable the ssh capability. I have remote management, screen sharing, file sharing, remote login, and web sharing enabled in settings, do i need anything else enabled, which ports exactly should I enable?
Assuming you want to maintain secure connections over the internet, I would suggest configuring your home router to forward a random high numbered port to your target home system's port 22. Most home routers allow this, but how to do it varies from manufacture to manufacture. A Google Search will most likely find instructions for your model router.
So lets assume you choose internet port 12345 to forward. Making an connect to your home system from the outside world would looks something like:
ssh -p 12345 [email protected]
That gives you an interactive shell login to your system.
If you wish to tunnel a screen sharing VNC session you would use something like:
ssh -p 12345 -L 5901:localhost:5900 [email protected]
Then using your VNC client of choice you would connect to
localhost:5901
Your VNC client would then talk to local port 5901, ssh would send this to the remote system's port 5900 which is the default VNC server port.
Using ssh to tunnel other protocols is done in a similar way, only the ports used will be different. Since I have only personally tunneled screen sharing, I'm not going to try to explain how to tunnel other protocols.
NOTE: You can specify as many ssh -L options on the command line as you like. Also the SSHTunnel utility can help you setup ssh tunnels.

How can I login remotely (not screen sharing)

Hi
Is there a way I can login to my desktop (running 10.8.2) and work remotely - without screen sharing?
I am talking about full desktop access, logged in remotely, without disturbing the session of another user who is logged in, and physically in front of the computer.
I have spent a long time googling and cannot figure out if such a solution exists, either within the base OS, Apple Remote Desktop, or commercial solutions.
In an ideal world such a solution would also be cross-platform so that the remote client could be either Mac or Windows.
Thanks for any guidance.

I answered my own question.
By setting up another account it is possible to remote login with a VNC client. When connecting to the mac the login screen is presented. Provided that you login to an account that is not the front account running on the mac, that session is not disturbed.
Thus it is possible to run with full access to apps and data, on another account and session separate from the session that is already logged on.
However, if during that VNC session you switch users and login to the front account, you now will be the only session and will be controlling that screen. After that point you have to disconnect the VNC client, and re-log back in in order to leave the front account undistrubed.

How can I remotely enable Screen Sharing remotely on 10.8?

Is there a way to remotely enable Screen Sharing from another mac? I'm using 10.8.

I assume you mean by remote login.
To enable via SSH to an admin account:
sudo launchctl load -F /System/Library/LaunchDaemons/com.apple.screensharing.plist
To disable:
sudo launchctl remove com.apple.screensharing

How to detect real desktop and remotely accessed(screen shared) desktop?

Hi All,
On Mac Os the Screen Sharing feature is similar to Remote Desktop Service. Is there a way to determine whether the terminal where we are starting the application(our own application) is real desktop or remotely accessed (screen shared) desktop?
For Ex:
I have booted(logged in) the Mac A sytem with user1 account. From another Mac B machine, i will login to user2 account of Mac A sytem using Screen sharing feature. My application has to run only on real desktop, not on remotely accessed desktop(screen shared). So Is there a way(programmatically) to determine whether the terminal where I am starting the application is real desktop or remotely accessed (screen shared) desktop?
Please guide me.
Thanks & Regards,
Vinay

Have a look at the 'Son Of Grab' sample code, it shows you how to grab elements of the screen individually.

Remote management under Sharing will not allow me to add admin user

I have just imaged my iMac lab to Lion. I am using Apple Remote Desktop 3.5. (I have used it for several years and know how to set it up and use it.) The problem I am having is adding my admin account to the list of users that are allowed remote management through sharing in system preferences.
The user list shows every other account, but will not show my admin account. I have imaged labs each year and have never experienced this issue. Not sure where to go from here. I am able to log in to each of the systems using the missing admin account but can't add that user to authorize remote management as it isn't listed. The sytems have recently been updated to 10.7.4.
For example, I have these accounts:
Me (admin)
User 1
User 2
User 3
User 4
When I go to system prefs>sharing>remote manage and click the Add to authorize only certain users, I only see User's 1-4. The admin account isn't listed...even if I am not currently logged into that account.
*I have just updated to ARD 3.6.

I can add "Administrators" under Remote Login just not Remote Management.

PLEASE HELP, SOMEONE REMOTELY VIEWING/SCREEN SHARING MY MACBOOK?

Hi - I urgently need help from anyone who knows about this issue - I am a very basic macbook user, and don't really know about all the different programmes etc. I believe someone ( the guy who sold me the macbook, who told me he was a mac repair person and programmer) has been hacking into the computer, using the remote access - there is a programmed called SCREEN SHARING but I cannot access it - and a bunch of other files such as odsagent etc - not sure if these indicate he is using the screen sharing/ remote access to my mac.
The reason that I believe he is accessing the mac, is that he downloaded all the files, so would clearly have access to passwords etc, there were loads of his old files, that showed pictures of people saying " target", and old files showing he was studying comuter/ mac programming. The first time I went online all of a sudden the computer froze, and two green lights showed on the num lock key and the shift key I think, the two keys were frozen, and the keyboard basically wouldnt respond, but the activity continued on the screen. This has happened a number of times since then, usually just randomly the keyboard freezes, and if you wait a while it goes back to normal - the mouse works fine, then one day it keep sort of freezing/ getting stuck/ pausing for no reason - the next day its fine again. He put in a load of software, which he has obviously been able to get round the need of liscening numbers, as he did not provide me with them. one day I saw a name "macbook pro" suddenly appear, and that it was tryin to connect/ share or something - this has never happened to me before with my old mac- it was like another computer was connecting/ sharing with my computer without my permission - this was when I was online. This has not happened since.
I am scared he is accessing the computer, because these things that happened, and because there is loads and loads of files and programmes, which sound suspicious, i dont know what they do, and I just have this dogey feeling about this guy, and the fact that there is screen viewing/ remote management files etc which I cant access, but I am not sure if they are being accessed.
PLEASE HELP - I FEEL LIKE MY PRIVACY IS BEING INVADED - I was speaking to my family on Skype and the green lights came on/ it froze, I continued with the conversation, but later I felt like he might have been watching.
If anyone can recommend an expert in the London area, that can check the mac to see there is nothing on there that is being used to remotely control/ screen share my mac, I would be very grateful - its just horrible using your computer, and always being worried someone is invading your privacy, and and downloading your files etc.
Sorry if I sould paranoid, but I have a strong feeling something is not right here.
Many thanks for your help in advance.

Since you don't know much about computers, disconnect your internet (wireless or wired) to prevent future unwanted access. While it is smart to contact Apple Communities, this is a criminal matter and you should consider taking the matter to the police. People like this will not stop with you. You need to list the private data that may be stolen and take action (cancel credit cards, change passwords, bank accounts, phone numbers, whatever you have cause to be worried about). If you can afford it, buy a new hard drive, remove the old one, and install OS X from scratch. Give your old hard drive to the cops. Make sure you turn the Firewall on (click the Apple up on the toolbar top left > System Preferences > Security) and uncheck any "Sharing" options (System Prefernces > Sharing). This event you are experiencing is unfortunate, and rare, but with a pro-active attitude you will come through it fine - and wiser.
EDIT
dgambler is right in that by purchasing a Snow Leopard disk (presuming you don't already have one) and performing a fresh install (it is easy) is a sure way to "take back" the controls of your Mac. You will need to study online tutorials for "wiping the drive" rather than a simple install. But you should let the police look at the hard drive before you do that - they will be able to see exactly what this person did.

Remote desktop / screen sharing / VPN questions

Hi all-
OK, I am trying to set up our all-mac environment to do something in particular - but I am only 'novice' level at VPN stuff and 'noob' to the Apple Remote Desktop and Screen Sharing stuff. I already have screen sharing set up, and also have back to my mac set up - but these both seem to be 'whole computer' control methods, where the remote user takes over the entire target machine. I have a different need, but don't know what terms to use to describe it or how I might achieve it.
Environment overview:
2014 iMac, 2009 13" MacBook Pro, 2009 17" MacBook Pro - all running Yosemite.
2013 AirPort Extreme handling the LAN, both wired and wireless. iMac is wired, MacBooks are wireless.
iMac: Two users (UserA and UserB, both admins).
MPB13: Two users (UserB as admin and UserC as standard).
MBP17: Two users (UserA as admin and UserD as standard).
I am wondering if this is possible to do, and if so - HOW? :
UserB sits at the iMac, and is using it. UserA sits at MBP17 and wants to get something done on the iMac, so UserA logs into MBP17 as UserA then remotes into the iMac as UserA and does what they need to do in UserA's iMac account - without making UserB (who is still sitting at the iMac and using it) stop what they are doing.
Hope this makes sense, and am looking forward to your input.

UserA must have a user account set up on the iMac that is different from UserB. With this set up when UserA initiates a Screen Sharing session with the iMac from the MBP17 they will just need to log in with their user account. When they do that a dialog box will pop up asking if they want to share the display with the user currently using the iMac, in this case UserB, or if they want to connect to a Virtual Display, which would give them their own environment separate from UserB who is already logged in and using the iMac.
Here is an example of the dialog box UserA should see when they attempt to start a screen sharing session with another Mac in which another person is already login in and using the Mac. In this case UserA will select the option to connect to the Virtual Display which allows them to work on the iMac without disturbing the user that is already using the computer. Note that the user already using the iMac may experience a slight performance hit because two users are using the resources on the one computer.
As for the acronym VPN, it stands for Virtual Private Network which is a protocol for making a encrypted secure connection over a public network between two or more separate networks. Screen Sharing actually uses a protocol called VNC which stands for Virtual Network Computing.

Remote Desktop & Screen Sharing not working??

Hello all,
I am trying to connect to a friends computer via the Finder's Screen Sharing, I enabled the screen sharing preferences under the System Preferences, put the password, etc and had him do the same and I am not able to connect to his system. I'm sure there is something else I have to do in order to get this to work. In the Windows world I had to use the VNC. But, I remeber reading in a Snow Leopard book that this is all that had to be done in order for this to work.
Best Regards,
freesparks

I know I could never get this working between two macs of the same OS (10.5.8) over the internet with the appropriate Sharing settings set up....
Im guessing both Screen Sharing and Remote Access through iChat DO NOT work anywhere but in a LAN?

Remote Access - Screen Sharing - possible to have a different session?

I was wondering of there was some way, maybe using X11, of doing screen sharing to my iMac but with a different session.
Can I log-in across the network and get a separate logged-in session from the one on the main screen?
If so, how do I do it? Is there a 'How to' somewhere?
I'd imagine something like setting up a Display parameter for X11 that can run remotely on my machine, so I can log on as a different person and run a different session without affecting what's on the main screen. Effectively to be multi-user access.

On a Unix or Linux system (and OS/X is a Unix system) you can have multiple remote sessions running under X11.
Mac OS X does NOT use X11 as its graphic engine. X11 is a side car on Mac OS X, provided so users that need to access Linux/Unix system which do use X11 have a way of displaying X-Windows output.
Mac OS X itself does not use X11 in any way. So even if you could do what you want, it would not get any of the native Mac OS X applications displayed on your system.
As someone else has pointed out, there is a trick with Fast User Switching and the Vine Server that can allow multiple users to access the system. It is a bit of a hack, and less than perfect, but if it works for you, that might be an option.

Install Mac OS using Screen Sharing or VNC - is it possible?

I've always wondered how to do this: Is it possible to remote install a Mac OS (in this case Leopard and up) using screen sharing or a vnc connection, when once the remote machine restarts and boots from the installation volume, you know longer have those sharing capabilities?
Essentially I want to know how do you control a remote mac installation without having the ability to activate screen or vnc sharing options?
In our office setting, what I'd like to be able to do is make an image of our installation disc and save it on our server, an remotely install it on other computers in the office.

how would a remote machine be controlled without screen sharing or vnc control if it's booting from a disc or networked volume?
The normal way to mass deploy an upgrade across many macs on a local network is to setup snow leopard server then you create an install image using a copy of a snow leopard disk. You can fully customise the install image with all your 3rd party applications etc. Then you just netboot each mac and the installation is automated.
see Create a Leopard to Snow Leopard Upgrade NetInstall Image
You would setup the server first. then you would have to setup dns correctly, then your users and groups. your sharpoints. Then when you build your image you customise it to suit your new network settings.

ARD Newbie - Remote administration/screen sharing

Here is the setup:
Admin: OS 10.5.8, ARD 3.3, Connected via Airport Express (802.11g)
Client: OS 10.5.8, Remote Management/Login enabled in System Preferences, Connected via Airport Express (802.11n), NAT enabled/ports mapped for ARD.
I still cannot connect to client's Mac via ARD. I choose File> Add By Address in ARD and provide the client's IP as well as User/Pass. ARD fails to verify.
Can someone point me in the right direction? Thanks!

Nevermind; wasn't forwarding to the right address. Works now.

Connecting to office computer remotely using screen sharing app

How do I connect to my office computer using the screen sharing app in the system?
Are there complete instructions somewhere that I can read?
I have a computer at home and at the office, both with sbcglobal router connections to the internet. I have read that /System/CoreServices/Screen Sharing.app will allow you to connect to computers over the internet, but the article I read did not have much detail.
So say my work router hardware internet address is 123.12.23.123
When the window open after I click Screen Sharing, do I put that address in there?
Is there a port I need to open at the office?
Is there some internet address for my computer besides the sbc 172.12.1.23 address that I should use instead?
Screen sharing has a computer setting under sharing "VNC viewer may control screen with password: abcdefg"
Where do I find more information about Virtual computer networking and how I can do it with my may and the software apple provides.
I appreciate your help.

The only way I have been able to do this is to use logmein.com to access my office computer, then using iChat, accept the invitation to share my office screen. One connected, I can log off logmein.
Has anyone found an easier way?
Thanks

Back to My Mac / Screen Sharing

I am trying to (and have had sporadic success with) controlling my desktop computer (at home, iMac, OS X 10.10) with my laptop (via Internet, Macbook Pro, OS X 10.10.1) through connecting through Screen Sharing from the Finder window's "Shared" computers. It's really hit or miss whether the iMac shows up in the Finder window, and I can't figure out why.
I've been all over websites and forum posts for information, and have learned a lot of things, but many of them are outdated. Here are some things I've done/learned about:
I can always log into my iMac through Chrome Remote Desktop, but I want the functionality of Screen Sharing.
I cannot simply start the Screen Sharing app and type in my icloud id, because that only allows viewing and not controlling the screen.
SSH through the terminal is hit or miss; it works more often than Screen Sharing does, but still not 100% of the time. I use it to copy files, but most of the time I need to be using the GUI.
A couple times the iMac showed up in Shared computers right after I did something, i.e. trace route to icloud.com or initiate a Screen Sharing session from the iMac, via Chrome Remote Desktop. Other times I've tried to jumpstart it like that and it doesn't work.
I've tried a variety of networks (home networks, workplace, mobile tethering) and I get different results every time, on every network. I might see my iMac in the Finder at work one day, and the next day it doesn't show up now matter what I do. So it must not be blocked ports in every case.
I've been taking notes almost every time I successfully connect, and I have documented cases where I can get it to work by (once again) going into my iMac via Chrome, disabling Back to My Mac and/or Screen Sharing, then re-enabling them. But of course, this hasn't worked consistently.
Any help or insight is appreciated. Again, this is all purely done over the internet, as accessing my home computer over a local network is of no use to me; I'm physically separated from it most of the time. (Most articles and walkthroughs teach people how to do it with their 192.168.x.x addresses, and they assume that your computers are always in your Shared section in Finder. This is not the case for me.)

That means that the Remote Management is turned on.
All you have to do is turn the Remote Management off if its not in use.
You may want to investigate how the Remote Management is being used to make sure you are not turning something off that needs to be on.
