Screen sharing question, again

I sometimes have to watch over somones computer on the network, and i dont want them knowing, how can i do this?

I think you missed my point altogether. I merely argued that I did not like providing such information without knowing the OP's intent, which was certainly not patently obvious. The "fact" is that the issue as originally posted was unclear. 'Network" could have been a home network or a corporate network. Further, if you don't understand the legal or ethical issues involved even for a business network, then you need to review some of the legal cases that create the precedents. Corporate spying on employees is sanctioned only within defined parameters. Although there may be technical issues involved in "how to," there are other issues as well. It's a shame some of you here are unaware of that.
And "number of posts" is irrelevant. I am not backing off, and I'm not passing judgment on those who disagree with me, I'm passing judgment on those ignorant of the legal and/or ethical issues involved in spying on others whether or not they be employees. Maybe a course in business ethics is appropriate.

Screen sharing questions

Merry xmas everyone.
I have a few questions I hope you can answer.
I just discovered screen sharing between my mac mini and macbook laptop via a physical ethernet connection using a linksys router (no wifi).
I go to the finder and see the other computer and click share screen, and it shows up beutifully. But without asking for a user name and password. I tried logging in from a guest account and it then asked me for a user name and password. So just to make sure for my peace of mind, both machines have the exact same user name and password (and .mac account), so is that the reason they can both connect to each other easily without the need to verify.
Is this share screen even possible via wifi (using Finder and not ichat)? Or just via a hard line connection?
2nd... is there a way to share the audio between both machines? My overall goal is to connect to my main computer from my laptop from my night stand so I can listen to my podcast, and have them marked as listened to, so that I don't have to wrestled with keeping two podcast libraries on two different machines sync to my ipod... ugh.
plus i won't have to drop the extra cash on an ipod dock.
Thanks
have a great new year everyone

1. While screen sharing is it possible to drag a document from the remote screen to the computer you are using?
No, but if you use iChat as your screen sharing tool you can copy the file(s0 manually that way. In Finder you could also simply both screen share and mount the filesystem of the mac.
2. Does screen sharing work over the internet (like web sharing)?
Not using the direct screen sharing abilities. But if the mac you're trying to control is set up to be accessed from the internet (with afp://) then you should be able to enter that address into the "New..." menu item window in the screen sharing application. The application is at: /System/Library/CoreServices.

IMac screen sharing broken again?

There was an iMac firmware upgrade today. Now screen sharing isn't working (again). Is anyone else having this problem?

I'm having this problem now, with one machine in my house; none of the above solutions work.
(I've seen the NetAuthAgent hang on the client before, where it's listed as "not responding" and killing it allows the client to connect. That's not happening this time.)
The symptom I see is that if I try to connect to my headless G4 Mac Mini, using any method I know about (clicking "share screen" in the Finder, using Finder's Go command and using "vnc://machinename", or using "open vnc://machinename" in Terminal, or launching the Screen Sharing app myself and using File->New and entering the machine name): the first time, nothing happens. If I then try again, I get the small black window. I can ssh into the mini and see the ARD and VNC processes running; if I use the ARD kickstart utility to restart the VNC server, it disconnects the client. But the client never connects far enough to show me the remote screen.

Snow Leopard and Screen sharing question

I followed the information in this article to use screen sharing between 2 SL computers and I can make the basic SS work. However, two items from this article don't function as described. It is an older article and I'm asking to see how it still applies to Snow Leopard users.
http://www.macworld.com/article/131094/2007/12/screensharepower.html
One item that doesn't seem to work is Bonjour Browser window. Launching screen share doesn't automatically launch Bonjour Browser. This is a small incovenience but it means I launch BB manually then cut and paste a device address from BB to SS.
The second item is the terminal command to add additional items to the basic SS toolbar such as the button to capture the remote screen to a local file. I've tried it but the additional buttons don't appear. Are their other commans I could use to locally capture a screenshot from the remote machine to my computer?
Are either of these features compatible in Snow Leopard? If yes, how could I trouble shoot my setup to find out why an item isn't functining as described.
Thanks!

What did you do to make it work?
In my setup, I am facing pretty much all the issues I saw on the forum around screen sharing. So from a Snow Leopard iMAC:
1. I can't even get the black remote screen when trying to get access to another iMAC 10.6.1 system. In most of the case the connecting window stays on for about 1 min and than closes; the screen sharing application shows nothing connected. Once or twice I got a black remote screen and once I think it did work well. Tens of times it just did not connect. Console messages show errors with NetAuthAgent (even that file sharing and screen sharing are enabled on the remote Snow Leopard system and the file sharing was fine but connection is slower than with leopard).
2. I can connect to a Leopard system but takes almost a minute to connect. I can access Leopard regardless of the screen sharing options and I never get a black remote screen.
All systems are in a LAN. Before Snow Leopard upgrade the screen sharing connection was instant on all systems.

Screen Sharing question

I'm new to screensharing and am trying to help my mother out....Once we were able to screenshare but ever since then, that option is grayed out in my iChat. However, when I log into my sons user and launch iChat, I can screenshare w/ my mother. I've checked all the settings in both users and just don't see any differences. Any ideas? Thanks

Parallels allows you to run a version of Windows actually whilst running the Mac OS (Unlike Boot Camp that needs you to reboot)
It can share an IP (problems for ichat) or have it's own.
The other problem is that some people find even without Parallels their Internet Sharing is ON and causes problems.
As far as I can see the setting is held in com.apple.ichatAgent.plist in your Users/(your account)/Library/Preferences
There also something in com.apple.ichat.plist itself.
I have Developer Tools installed and can look at the .plists with Property List Editor.
com.apple.iChatAgent.plist clearly shows a setting for Setting.BlockARDAvail (links to Apple Remote Desktop) and setting of 0 which when I change the setting in my iChat changes.
However having the Preferences open I can see that the time the other .plist cahnges also matches but looking though the items I can not detect which item it is.
Despite that background info I would suggest deleting both and restarting iChat.
I would point out that deleting com.apple.chat.plist itself removes Saved Status Messages, Colour and font choices for Text chats. It is likely to remove any reference to Backdrop you have added the the Video Effect and Backdrops.

Screen Sharing and Talktalk UK

Apologies if this duplicates what others have said. I've spent a lot of time trawling through here but I'm wondering particularly if the problem I'm having might be related to talktalk, my dad's provider.
1. I have an intel iMac running leopard. Comcast is my provider.
2. I can screen share both ways with my father in law in Rochester NY. He's on Roadrunner and has a G5 tower running leopard.
3. My Dad is in the UK with a split new macbook running leopard. He's on talktalk. I can share my screen with him but HE CANNOT SHARE WITH ME. When we attempt to do this, "screen sharing with <me>" comes up on Dad's screen, and we both get the audio connection, but at my end the small window with "connecting" just hangs on the screen. Wheel goes around endlessly, etc.
Because I can connect both ways with my father in law, I am assuming the problem is at Dad's end (although I'm not sure). Here's what I've done:
1. Our quicktime streaming speed is set at both ends at 1.5 Mbps, although I've tried the default too.
2. Bandwidth is 500k at both ends, although we've also tried none.
3. Firewall -- We both added ichat as a specific app and this actually made things worse -- when I tried to screen share a "failure" message came up on screen, and we couldn't video chat either. We both then reset the firewall to Allow all and at least then we could video chat.
4. UPnP is on at both ends.
The only thing I haven't tried at his end is the stuff I've read on here about Anonymous Pings, but it's really hard to do this when dad doesn't really know computers and when I don't know what the Huawei (this is his router) menu looks like.
Dad also has an Apple airport router which he as yet has not connected up. I'm wondering if he installs this between the Huawei and the ibook things might improve (I'm hoping against hope, really!).
Any suggestions, folks? Any ideas gratefully received.
Thanks,
Dr D

My guess is that your problem is not with your set-up but with TalkTalk. In my experience talking to my parents, who are also on TalkTalk, they tend to throttle their network for non-web traffic to the point where it's barely usable (if at all). For us, iChat usually exits the connection attempt with an "insufficient bandwidth" error message.
We have had more luck with Skype, but obviously that does not help with your screen-sharing question. Other than trying to change ISP, all I can think of is to try "calling" at less busy times.
Cheers,

Screen Sharing freezing and high CPU usage

Hello all,
I use screen sharing to remote my mac mini as a media server connected to ma HD TV to play movies, music and surf.
Since I upgrade to mavericks on my macs (Macbook Pro Retina and my Mac Mini) I have some troubles with the screen sharing feature.
No problems with the login step, the connexion is fast, all permissions are OK (I saw there were a bug with some RDP release) but sometimes, when I use fullscreen software as VLC, Firefox, etc (not the native apple full screen feature, I just clic on the + at the top of the window), my sreen sharing freeze and I can't do or move anything on the remoted mac mini. I'm unable to close (or reduce) the screen sharing app too, it's totaly busy (But I can see the movie or the website on the 2 computer, there is no deconnection)... I have to kill the process through the monitoring activity.
During the freezing time, I try to use vnc light from my Iphone and I have no problem, I can move the mouse, reduce le VLC windows... As soon I reduce the VLC windows, the screen sharing works again. I also use the logitech TouchMouse to remote the mouse, everything work fine.
Here are a screen shot of the monitoring activity of the Mac running the screen sharing app, we can see that there is a very high CPU usage when I use VLC in fullscreen on my mac mini. The first is in normal mode. The second is in freeze mode. Screen Sharing is named "Partage d'écran".
Can someone help me to fix that, everything works fine with Mountain Lion.

I have a Macbook Pro 13.5" 2.8 GHz 4 core (2 real, 2 hyperthreaded) i7 machine running with 1920X1200 display, 3 virtual screens and VMWare adding a few virtual screens (full sized). I have another Macbook Pro 15" with 2.6 GHz Haswell 8 core (4 real, 4 hyperthreaded). I see the problem using Screen Sharing on the 15 inch (Retina screen) mode simulating 1920 X 1200 pixels using Screen Sharing to the 13.5" Macbook Pro.
When I get the ScreenSharing problem, I have identified it as related to the VMWare screen on the 13.5" Macbook Pro being shown through Screen Sharing on the Retina Screen. Before you conclude it is a VMWare problem, the computations are only on the Screen Sharing client side, not on the server side running VMWare. The mouse gets unusable through Screen Sharing. If I physically move the mouse on the 13.5" Macbook, no problem. If I switch virtual screens, the Screen Sharing goes to normal processing.
I see an appearance of a compute-bound thread on the Screen Sharing client. It takes 100% CPU on one thread, the machine as a whole is 12.5% busy (the performance monitor considers all 8 threads as equal when in fact, they are not).
A few more pieces of information. The VMWare client ends up having a lot of overlapping windows with a lot of changing graphics. My mouse runs into problems especially when it is overlaying a changing plot (Perfmon running in Windows 7, or updating email client). It does turn out that VMWare has a "native" VNC server built-in and I tried to connect to the virtual screen using the Screen Sharing Client on the machine with computing problem and voila!, no problem. I end up having a Screen Sharing Client running native running screen (supposed to be VNC, but I have not verified that) sharing protocol on a virtual screen that is NOT the VMWare virtual screen and a separate session using actual VNC protocol using the VMWare VNC server. It works perfectly fine.
If I may hazard a guess, I think I know what the bug is, or at least, what is the nature of the problem that I have. The rest of you may have a different bug. When I have difficulty, it is because I am on a window that suppresses the dock, both in remote virtual screen and on the local machine showing the screen. Two docks are suppressed, one remote, one local. Throw in overlapping windows with changing graphics in the overlapped windows and toss in a mouse on top of that. I think that the Screen Sharing is trying to refresh overlapping windows with mouse and going through the suppressed dock calculations and never converging on what the picture should be. The mouse ends up being the visible cue that shows the time frame for iterating the windows - flickers with a timeframe of greater than a second. That is far greater than the screen update time. It is totally compute bound with all the overlapping stuff that it is deconflicting. At least, that is what I think is going on.
Meanwhile, the VMWare VNC server appears to send out a single graphics context and causes the Screen Sharing client to converge to a picture. Note, the mouse appearance is very different when attaching to the VMWare VNC Server rather than the ScreenSharing native server. I see two mouse renderings, the virtual machine remote and a mouse rendering from my Screen Sharing client side. They are mostly in sync in position unless I move the mouse very quickly. If I use Screen Sharing client and server instead, I usually see only one mouse, the client side's mouse rendering.
I have a solution for my problem. It is similar to using a different VNC server/client pairing. I will use a VNC server for the systems giving me trouble that is not Screen Sharing Server exercising a probable bug in the Client (though, it could be a problem in the design of Screen Sharing itself).

How do I get screen sharing to work again

I have a mac mini server running OSX Lion 10.7.4 Until powring this down over the weekend, it had worked beautifully. I coould connect, access shared files, screen share (as I am running in head less) as well as access it via Server Admin from a remote computer.
After restarting, I can still share files, but am unable to access the sceen share or administer remotely. The odd thing is that when I connect it to my TV I can then also access it with screen share from another MacBook Pro as well as use server admin for remote admin. As soon as I run it headless again, I cannot access it via screen share.
I have noticed that the screen share finction has changed from before, so am wondering if this has anything to do with it.
I have not chnaged any settings on it. Firewall is the same as before, filesharing and screen sharing is enabled and I am trying to access it as a registered user.
Any help greatly appreciated.
Thanks

graccoat, I've run the chengeip thing now and it has reported the following:
primary address = 192.168.0.14
current hostname = applepip.local
The DNS hostname is not available, please repair DNS and rerun this tool.
dirserv:success = "success"
oddly enough, now that it's connected to the TV again I can access with screen share.
The reasosn the IP address is different to what I gave you earlier is that It's conected to my router wirelessly now, but usually connects through ethernet.
I have also noticed that the hostname returned using the changeip command is different to the nme given in the sharing settings panel.

Screen sharing in Lion question

I am trying to set up screen sharing in my local network.
I am using a MacBook with latest Lion as server to which I am trying to connect.
I am connecting with a Powerbook 12" 10.5.8 without problems and controlling the MacBook via Screen Sharing.
I am unable to connect to the MacBook using a MacBook Pro with same Lion installed.
Before that I used the same setup to try out RealVNC. Again, the Powerbook connected to the MacBook without problems, but the MacBook Pro is unable to connect.
Any suggestions?
Thanks.
Oops, posted in wrong forum. Will try under Lion. Sorry.

I use mocha vnc and have the same problem but you can get around it by making a simple macro #T (no space) then your password (no space) #R . When you see the login screen recall this marco and then press the enter arrow in vnc and you will log into lion. Makes it useable until a software fix.
This works like a charm!
I was also able to input the account password and make it work. Don't know what I did, but it is now working in Mocha. I like VNC Viewer too, but sometimes I am able to input the password and sometimes I can't.
Thanks.

Screen sharing security question

I recently set up my imac to allow screen sharing from my MBP. On my iMac I randomly see the screen sharing icon appear in the menu bar despite not being connected. Is this normal?
Also i setup security so that it should only be me that is able to connect via password to my iMac, yet there is aslo an option to connect as a guest which connects & shows the imac screen & allows me to do things.
I thought the whole point of setting access only to me was that no-one else ( eg guest) could connect.
i am a bit baffled here, can anyone help me out?
TIA,
john

I would not consider the presence of the screen sharing icon normal. I encourage you to open terminal and run the command
netstat | grep vnc
the next time you see it. This will return either nothing (bringing you back to the prompt ending in $, or return a line such as this:
tcp4 0 39 10.0.42.116.vnc-server 10.0.42.243.54233 ESTABLISHED
In this case, my Macintosh is 10.0.42.116, and the computer connected to it is 10.0.42.243.
By this method you can determine if there is a glitch causing the icon to appear or if there is actually a connection being made to your Macintosh.
What you are probably experiencing with the guest account is a bit of confusion related to how Finder thinks of computers.
The Guest/User Account is not for Screen Sharing, but for File Sharing.
When you clicked "Share Screen..." the first time, regardless of if you connected to file sharing as Guest or Registered User, you got a box requesting "the username and password to share the screen of (computer name)." There, you probably selected remember password in keychain, and that is why you are not being prompted again, and why you are connecting to screen sharing as a guest. (You're actually connecting to screen sharing as your registered user, but you are connected to file sharing as a guest).
To change this behavior, (on the client Mac) navigate to Applications, Utilities, Keychain Access. There, you will find an entry with a blue @ sign as an icon, and your destination PC's name. The Kind will be Network Address and when you select the line the "Where" in the info viewer panel will begin with vnc://. When you find this line, press the delete key to remove the saved password, and don't tick the "remember" checkbox again.

Screen sharing and AIM account question

In the Apple docs it says:
"You can share screens using AIM (including me.com and Mac.com), Jabber, Google Talk, and Bonjour. You can’t share screens using iMessage or Yahoo!."
I know I can simply create a free AOL/AIM account for this. But how does one get a me.com or mac.com address? Are those old, no-longer-available services?
What do most people use for screen sharing. I've been using my AIM account, but was unable to get it to work yesterday with some people who created new AOL accounts for this purpose, even though I see them online. They don't get my requests, except for one person. And even if she accepts the request we don't get connected. And we can't video chat either.
Thanks,
Doug

I accidentally deleted Screen Sharing app from my Macbook Pro (Mountain Lion). Can I download it again?

Any chance of finding this as a download?

Hi Carolyn;
Well it seems like I wasn't as stupid as I thought. I initially thought I'd deleted an app called Screen Sharing from my applications folder, as after I'd finished my session of deleting unused apps, the availablity of the "Share Screen" button in the Finder window (under the "Connect" button) when you click on a shared computer in the home network was gone.
Now it seems it's back.
Problem solved!

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 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.

Screen Sharing Problems/Questions

Greetings!
I really like the screen sharing feature of Leopard, however, it has a serious problem, but probably only for me, as I can't find anywhere on the internet where my problem is mentioned.
Whenever I attempt to drag ANYTHING on the other person's computer, the mouse pointer freaks out and jumps to a random place on the screen, or even offscreen entirely. After it has completed its jump, it drops the drag leaving the window I was dragging in the wrong place, or moving a list of files to the wrong place.
This renders screen sharing basically unusable for me.
I've confirmed this bug, both ways, with two seperate systems. I can't drag on their machine and they can't drag on mine. All three of us turned off spaces and removed any external monitors to make sure that wasn't the problem. None of us are on an internal network... this was all done with iChat over Google talk on an internet connection.
Can anyone confirm this bug?
Has anyone found a fix for this bug?
Thanks!
-Sastira

Umm.
I am not sure you are doing it right.
Go to the File Menu.
iChat Theatre item.
Navigate to File (Can be Movie or Pic or PowerPoint etc)
Click the share button.
The iPhoto Share works solely with iPhoto but the principles are the same.
There should not be any Dragging involved.
TO Send an Item as a file or include a pic in a text chat is different.
In that case it is a quetion of dragging the item the the Text entry field during a Text chat or dropping it on a Buddy in the Buddy list.
Sometimes with a New buddy (freshly added) the second option of Dropping it on their name can be more successful.
