Screen sharing via VPN

Hey guys,
I finally got my VPN connection working remotely. I was told it would be like I was actually on my local network...and it pretty much is except I can't do a screen share. Is there anyway to make this possible over VPN? When I'm locally connected I can screen share via any machine on the network.

When you're on VPN you can do anything you can do locally over the LAN, except use auto-discovery protocols such as Bonjour to locate servers/services (at least without jumping through several other hoops).
This means that you can certainly use VNC to share your server's screen but the server won't appear in the Finder's sidebar - you'll need to know the address of the server to do it.
Just open Finder -> Go -> Connect to Server and enter the server's address in the form of:
vnc://a.b.c.d
(where 'a.b.c.d. is either the ip address or the hostname of the server).
The same is true for other services, too - you can get there, but you have to know where you're going first.

  • Screen Sharing and VPN functionality with ARD

    Can somebody with ARD tell me if the following setup is going to work? There's no demo version so I can't tell if it's going to be worth 300 dollars.
    I have a number of local machines in a network and a couple external machines in other parts of the state that VPN in to the network. I want to be able to have a local machine that can screen share w/ voice reliably with these guys.
    "Reliably" being the key. iChat screen sharing and VNC alternatives do not work reliably at all. They crash, they are slow, they sometimes disconnect video and keep the audio. Or some days they work perfectly, but that's few and far between. Zero-conf services like MacHelpMate work just fine, but I'm reluctant to pay 600 a year for something like this.
    Is ARD going to be able to be able to fix this problem for me, or am I really just going to end up with more of the same issues?

    ARD uses VNC for observation and control, so if you're having problems with iChat screen sharing and with VNC clients, I would not expect that ARD would be any better. My suspicion is that your network and/or VPN are cutting things off, since most people have found iChat sharing and VNC to be pretty reliable, but without being able to perform reliability tests on your network to VPN clients, I can't say for sure.

  • Screen Sharing via iCloud on Lion Freezes at Login Screen

    After updating to OSX Lion 10.7.3, screen sharing between two computers via the Internet allows me to connect to the remote computer and see the remote user's login screen, but as soon as I click on a user to login, the screen share image freezes before I can enter the user password. 
    Using iCloud Back to My Mac because all machines have the same Apple ID & password. Exact same setup worked before the 10.7.3 upgrade, but it could be coincidence. 
    Details:
    Can see the remote computers in my finder,
    Can click on them and connect successfully using either the Apple ID or the name and password a user that is allowed under Sharing -> Screen Sharing,
    When clicking on "Screen Share," the computers connect and I'm prompted to either "Ask to Share the Display" or "Connect to Virtual Display"Since there really isn't anyone using the computer, I select "Connect to Virtual Display"
    After clicking "Connect to Virtual Display" the Screen Sharing window shows the remote computer's login screen, whcih shows the user names, their icons and "Sleep" "Restart" or "Shut Down" on the bottom of the screen.  One user has an orange circle with a white checkmark next to it. 
    Previously, I could click a user's name or icon, enter the password and control the remote Mac.  Now, not amount of clicking works. 
    Have tried disconnecting and reconnecting as different users or using Apple ID without changes in the perofmance. Have restarted both machines. 
    Any help?

    I'm having the same problem screen sharing to a Lion 10.7.3 machine, I get this message.
    However, it works just like it used to when I screen share from a 10.7.3 machine to another Mac running 10.6.8.
    Any thoughts?
    Thanks!

  • Video/Screen Sharing via 3G connection not possible - port restrictions?

    I'm running Jabber-based iChat AV 5.0.3 sessions from my MBP connected to the Internet via a wireless USB modem 3G/UMTS (German Telekom D1 network). My buddies are connected to the Internet via regular broadband connections (DSL). I have set up a hosted Jabber server via Dreamhost (without SSL, port 5222 used).
    Status Quo:
    - Contact status of remote Jabber users shows up properly. All buttons (text chat, screen sharing, video) are available (not greyed out) on both sides.
    - Text chat works fine.
    - Video chat and screen sharing can be invoked from both sides (confirmation window shows up), but after confirmation the initiation process doesn't finish successfully. The video/screen sharing session doesn't run. *iChat AV shows a message indicating that it doesn't receive an answer from the remote user device.* If the iChat session is initiated from a buddy's computer, the buddy gets the same message respectively.
    - For testing purposes, I changed the internet connection on my MBP from the mobile 3G USB modem to a regular *DSL broadband connection (same ISP, German Telekom). In this scenario, video/audio calls and screen sharing work flawlessly!* Therefore, I assume that the problems in 3G connection mode is caused by the ISP (German Telekom) blocking/restricting ports required by iChat AV for initiating the video call and streaming the data on their 3G network.
    Is there any way to bypass ISP restrictions, by either changing specific iChat AV port settings on both ends (client devices) or by port forwarding? If yes, which settings should I change? Unfortunately, it's couldn't find any document indicating which ports are opened/allowed by German Telekom's 2G/3G (GSM/UMTS) network.
    Below is an excerpt of the error message produced by iChat AV:

    Hi,
    Does this 3G device have any set up functions that are on your Mac ?
    If it does not it is likely that it is wide open to all Port (65535 of them).
    I presume that in System Preferences > Network you see a Public IP when using this device ?
    Again this would tend to pint to all the ports being open.
    Is there anything on the ISP's web site that suggests this device is unsuitable to be used with VoIP or SIP connections ?
    VoIP (Voice over the Internet) uses the SIP connection process the way iChat does.
    Most likely the issues is the way packets are sent.
    When you do a download, for instance, do you find the speed increases in the first few minutes ?
    When some data packets are sent over the Internet the next one is not sent until confirmation that the first has arrived.
    This Latency effects Point to Point WiFi (antenna to Dish on House) and satellite connections mostly particularly when it is a two way thing.
    It can effect Mobile/Cell phone type connections.
    What sort of Speeds are you getting on the 3G device ?
    http://www.speedtest.net/
    Do these seem to get faster as the time proceeds ? (this can be difficult to spot).
    The Log mentions one end being at just over 2Gbps although it does not make it clear which end.
    As the Remote end is the end that reports "Router: Port Restricted" and it works over standard DSL we have to presume they have the ports open.
    You could try restricting iChat 's Bandwidth in iChat menu > Preferences > Video Section to 500kbps (try it at both ends)
    If that does not work try 200kbps
    This may stop iChat from trying to send data too Fast for the Network Connections.
    Realistically there are a few too many variables here.
    It could be Speed of data throughout at the Initiation point. (Slow Start up of data transfer)
    It could be an Internal setting preventing SIP.
    It could be that the 3G network sends and receives data by different routes.
    (I have seen this once when a ISP was repairing some Cabling. To maintain end user speeds they managed their own network to split Incoming and outgoing data to the end point.)
    iChat does not like this as it checks the IPs and the Hops (number of intermediate stages/servers) and if the data is different it will not connect (Man in the Middle attack protection).
    I can't remember the last time I knew of someone being successful with either an 3G USB dongle or a 3G phone as Modem (internet Sharing).
    Despite my ideas I think you will be unlucky and this will not work.

  • Improve Screen Sharing, via dedicated Ethernet

    I have 2 mac pros on a network together.
    A >>> Network >>>B
    but I can also join via ethernet A >>>> B directly.
    With screen sharing it using port 5900.
    Is it possible to port only this traffic via the ethernet port2 (A>>B) so that it doesn't get restricted by other data?

    Seem to have sorted it now after much fiddling.

  • Screen sharing via Airport

    I have a 500mhz G4 running 10.4.11 with Airport card that I'd like to set up behind my TV and use for TV recording. I want to do this without having a monitor or keyboard connected.
    I can setup screen sharing so I can use screen sharing with my Macbook Pro via ethernet but if I want to do it via Airport, it seems that I need to set it up manually every time I start the G4.
    10.5 allows this but I would like to stay with 10.4 on this machine.

    In answer to the first question - Yes, I have a .Mac account, and both machines are set to access this account. With reference to the UpnP question - harder to anwer. I would guess I do at home, as Screen Sharing works there (though of course this leaves open the question of AppleTalk enablement under either AirPort or ethernet). Not so sure about work - do you know of a way I can check this?
    Thanks - you may be on to something.

  • Configure Screen Sharing via ssh

    I have a couple of macs sitting at a remote location that currently has no people there. i need to get into the machines via VNC (have windows at my current location), to see something on the screen. unfortunately, last time i was in front of these machines, i turned on screen sharing, but did not enable the VNC password option. is there a way to configure that option remotely via ssh? I'd really hate to have to drive 2 hours to go hit a simple tick mark on a screen...

    You can use the ARDAgent kickstart tool to set the password for VNC access. The command to do this is...
    sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/k ickstart -activate -configure -clientopts -setvnclegacy -vnclegacy yes -setvncpw -vncpw YOURPASSHERE -restart -agent

  • Will Firefox Hello support screen sharing via video chat?

    First of all let me say a BIG thank you to all the developers who contribute to Firefox (and all Mozilla projects for that matter). I know countless dev hours goes into the project and I really appreciate all your hard work.
    To my question, I realize Firefox Hello is based on the webRTC standard and there are a many other options available for screencasting, but it would be incredibly convenient to have that feature natively built into Hello. Are there any plans to support screen sharing in the future?

    hi, yes screensharing features are in the roadmap for firefox hello (and already present in development versions of the browser) - this feature might land in firefox 38.

  • Screen sharing via iChat

    Not really a server question I know, but I wondered if anyone was experimenting with iChat screen sharing as a support tool. Most of my customers are set up for iChat using my own server and IM me with questions from time to time. I've just started installing Leopard on a few clients and wanted to try out the screen sharing. My own machine is a 17 inch Powerbook and it is looking as if there's a limit to the desktop size of the remote machine. Trying it with this particular client's machine, which is a 15 inch Macbook Pro with an attached 20 inch Cinema display, iChat screen sharing never finishes initialising. But if I reduce the resolution of the Cinema display from its default to, say, 1344x840 it works - and shows both remote screens (the Macbook display and the Cinema display).
    Am I discovering that it'll only work where there are no displays connected to the remote system that have a higher resolution than the local one(s), or is there a glitch here that can be fixed? Given that it just 'hangs' I'm tempted to think it's a glitch and not some designed-in limit.

    ...should have mentioned - the connection is jabber of course, the server is 10.4.11 and both machines are 10.5.1 with 2Gb RAM.

  • Screen sharing via ethernet

    I bought an Airport Express to replace the flaky AIrport signal I got on my MacMini. I connected it by ethernet to the Mini and set it all up. Browsing and streaming are now much more stable as is screen sharing from the Mini to the MacBook and iMac, but I now can't see the Mini if I want to share the other way round.
    Any advice?

  • Screen sharing via Back to my Mac

    I'm away from home for work.
    I have my iMac at home, connected to my internet connection which I know is working.  It is on the DMZ on my network so there are typically no issues with blocked ports and the firewall is turned off.
    With me I have my Macbook Pro. Both machines are on 10.10.2
    When I sign into BtmM on both machines the iMac shows up in finder on the MBP, however Finder says not connected and when i click share screen I get connection failed.
    What can I do to troubleshoot this to try and find what part of the chain the issue lies in? I won't be home for another few weeks, but should be able to make changes remotely (the iMac is on, I'm using it to chat to my partner daily and managed to connect remotely via Team Viewer tonight)

  • Ipad screen sharing via wifi

    hello,
    i have a big problem.:) my boss want me to connect ipad to a computer / mac via wireless. and he wants to see ipad screen on the connected computer. for example when i open a app like ibooks or something else he wants to see same action on the connected computer. like a cloned screen property on pc's. i found some application like idisplay but it is mac /pc screen on ipad (extended screen like second monitor),t doesnt work for me unfortunately! i want opposite of this application. it is possible ?

    Sorry, but that's not possible. It's not even possible to show the iPad's screen (other than output of specific apps) via a directly-connected external monitor.

  • IPad screen sharing via 3G?

    Hi,
    does anyone know of a way to share the ipad screen to a Mac Computer via 3G (or alternatively to another iPad)? I would just need to see the screen, I do not need to operate the ipad via what I see, e.g. recieving low resolution screen pictures as jpg or video stream would be ok....
    Thanks,
    Joe.

    I am not aware of any such app. I Googled and did not find anything. You can control a computer via an iPad and use the iPad as a remote monitor for your computer though.

  • Back to my mac screen sharing no longer works since Mountain Lion release, even on Lion

    I've used screen sharing via iCloud and back to my mac between a 2007 macbook and a 2010 imac.  Both computers are still on Lion but screen sharing stopped working when Mountain Lion was released.  I've read a number of comments on this forum that people were having trouble since upgrading to Mountain Lion, but I don't think that's the problem b/c I haven't upgraded either machine.  I think the problem is something Apple did in preparation for the Mountain Lion release date and it seems to have damaged screen sharing functionality.  Anybody else experiencing this or have a fix for it. 
    As for the specifics, I can still see my "other" machine under shared and can click "share screen," it usually searches for a couple minutes, then pops up the password dialogue box, but then searches for a while and eventually the password box closes, "screen sharing" stays open, but there are no windows associated with it.

    I have the same problem, just today (although I'm still running 10.6.8). Every morning I turn on my main Logic mac then fire up my 2 slave macs, connect to them, activate Screen Sharing, and get going.
    This morning I tried it, connected to the other macs as usual (I can see/access/alter their hard drives from my main mac) but when I click "Share Screen" I just get the "connecting" dialog box & it just keeps going.
    The weird thing is, when I put my laptop into the network via wifi, I can screenshare my main mac's screen (all 3 of them, actually!)  but not my 2 slave macs that are ethernet'd to the main mac.
    I've tried every solution I could find via google, and nothing is working.

  • IChat screen sharing and video not working on MacBook but works on Mac pro

    I have a MacBook and MacBook pro. Both have the lion os 10.7.2. I can use iChat on the MacBook pro for screen sharing, video chat, and text chatting, with others remote to me. However, I can only do texting with the MacBook.  I can do screen sharing via Finder between my MacBook and MacBook pro. I can do FaceTime between both systems. I can also do FaceTime between the MacBook and anyone remotely.
    I also tried installing teamviewer on the MacBook, and on a remote MacBook..... And I get the same results where I cannot share the screen, from the one that has not been working.
    I have checked the settings under system preference and made sure screen sharing was enabled. I have checked under iChat under video to make sure screen sharing was checked.
    The macbook that is having this problem is configured for AIM for iChat
    I have run out of ideas. Any suggestions on what I might try?
    Thanks

    Ok,
    I will list the ports in greater detail and point out when iChat uses them.
    AIM Login and 1-1 Text Chatting
    iChat version 1  through 5 will Log in to the AIM server on port 5190 (TCP Protocol) by default.
    Since iChat 2 we have been posting here that the AIM servers allow a Login on almost any port and have been suggesting port 443.
    This is used by both Web Browsers for secure Login to some sites and by the Mail app with some mail servers.
    It is also below port 1024  (most domestic routers have the ports above this figure closed)  In some campus situations using port 443 will normally allow at least Login and Text chatting.
    iChat 6 uses port 443 by default.
    File Transfers (AIM)
    When doing File Transfers with AIM Buddies iChat will move to using Port 5190 on the UDP Protocol.
    This cannot be changed.  (This invokes the little Message about Starting Direct IM in an open Chat)
    It also uses this port for Pics-in-chats, dropping Files on a Buddy's name with out a Chat or sending other files that are not pics.
    In the case of Port Forwarding some devices don't like port 5190 being forwarded "twice" which is another reason for moving the login and Text chat port.
    Jabber Logins
    No matter what Jabber server you use ichat will use one of two ports (5222 and 5223)
    Which one it uses is dependent on whether it needs and is using an SSL Login or not.
    SSL Logins use port 5223 and NON SSL one use 5222 (ticking or Unticking the SSL box on a Jabber account will automatically change the port).
    Google Talk is the exception in that it allow a Login on port 443 as well.
    The First Apple Doc I linked you to says iChat uses port 5220 in Jabber.
    I run Little Snitch and have never seen any version of iChat use this port at any time.
    Bonjour
    Any Mac to Mac Connection or Mac to any Bonjour able peripheral will be on port 5353.
    This is normally opened (Preset) in the Mac Firewall for the Finder/System side of Sharing.
    iChat needs and uses two other ports  (5297 UDP and 5298 on both TCP and UDP)
    As they an LAN Side connections the router would normally pass them.
    At iChat 3 there were issues with the Mac Firewall (it included UDP set up and the preset in the firewall only listed them and TCP so we had people add all the iChat ports  (you had to manually enter them in Tiger)
    A/V Chats
    No matter which Buddy List you start from iChat will do A/V chats the same way.
    The Visible Invite you or your Buddy sends is on port 5678 (UDP)
    In iChat 3 and earlier iChat then moves to port 5060 to send the SIP Connection Process invite behind the scenes  (SIP = Session Initiation Protocol)
    Port 5060 is one of 4 ports internationally agreed for SIP (How VoIP phones connect) (5060-5063).
    Although ISPs were not supposed to block Through traffic many started blocking End users  and then Charging them to open these ports (Many ISP were telecom companies that were losing long distant Telephone calls monies).
    The SIP process then in iChat 3 contacts a server run by Apple for this purpose (Snatmap.mac.com to give it it's full name).
    This acts like a old fashioned telephone operator connecting the call.
    SIP is a text based process.
    Your end "Calls" the operator.
    The Operator "Calls" Buddy.
    Buddy Accepts
    iChat then negotiates the ports to be used.
    In iChat 2 and 3 it uses 4 ports (vid in Vid out, Audio In and Audio Out) from "the group of 20" starting at the bottom (16384 to 16387 normally)
    Three and 4 way chats uses more ports (which is why 20 are set aside)
    In iChat 4 Apple realised the issue with the 5060 port and changed the way iChat worked
    Since then it has Sent the invite on Port 5678 but then moved to port 16402 (it starts at the top of a smaller group of 20)
    All Video and Audio traffic is also now on one port  (so no need for 20 ports and iChat now lists 10).
    NOTES so Far.
    File Sharing during a Chat converts the Chat to Direct IM for AIM Logins
    This is Peer-to-Peer in AIM
    A/V Chats are Peer-To-Peer and you can actually log out of the Buddy list and continue the chat. (The exception is using iChat 6's  AIM Video relay option)
    Screen Sharing
    Screen Sharing is an Audio Chat with a VNC connection along side.
    Both bits have to wok to avoid the Pop-up to send to Apple and the Log that contains.
    The Audio part is on port 16402 and the VNC part is random. (So random it is different every time you do it)
    The reason it is classed as an Audio Chat+ is so the AppleScript for Auto Accept can  filter out Screen Sharing connection and Not Auto Accept them.
    This does have a knock on effect as far as your Router is concerned as already mentioned earlier.
    You cannot Forward or Trigger the random Port so you have to use UPnP in your router to open the ports.
    NOTES
    Jabber File sharing may possibly be on port 1080 as listed in the Server Article I linked you to (I have also seen it written about in other stuff I have come across)
    However Little Snitch does not seem to confirm this either.
    Most time it will be peer-to-peer like the AIM connections for this.
    However some Jabber servers do not seem to allow this and have this Jabber65 Proxy set up which passes things Server to Server in between it leaving your end and arriving at a Buddy.
    This on  Port 7777 but you do not need to open this port (unless you are running a Jabber server)
    I have yet to test File Transfers using a Yahoo Buddy List in iChat 6.
    AppleCare and Geniuses.
    Previously I have been contacted by Geniuses in Stores asking to test customer's iChat.
    They and the Applecare people have details about Apple wants an designed the App to work.
    What they don't have is the knowledge about what it takes to set it up in the "real world".
    There are literally thousands of Makes and Models of routers.
    Some like the Thomson-Alcatel brand state they are SIP/VoIP ready but this means the router strips out all SIP Data trying to send it to a Phone.
    Early models of Alcatels can get around this with a tweak. Later models can't.
    Motorola devices tend not to have UPnP.
    Apple Base Stations have Port Mapping Protocol instead of UPnP and this needs setting up.
    The Zyxel range definitely does not like the dual use of port 5190 and does much better using UPnP (You almost certainly have to do your AIM login on port 443 with these).
    1. I have two computers (MacPro and MacBook Pro) that are both running Lion 10.7.2 and both running iChat 6.0.1.  <<-- Fine
    2. The Netgear router model is: WNDR3700.    <<<<---  With any Brand there are exceptions and I do wonder about this one
    3. The firewall for both Macs is turned on and in the advanced area iChat is listed as being "allowed."  <<<<---- Fine
    4. In iChat, under the video options, "Screen Sharing Allowed" is checked.                                        <<<<<---- Fine
    5. In System Preferences, "Screen Sharing" is checked and this is for "All Users" at present.               <<<<<---- Not Required
    6. There are two separate AIM accounts being used for iChat purposes.                                            <<<<<----  OK
    7. In iChat preferences, each AIM account is "Enabled" under "Account Information" and the "Server Settings" show the Server as "api.oscar.aol.com" and the Port is "443" and "Use SSL" is checked.                                <<<<---- As it should be
    From this and the other info in the first port it was only the router set up that seem to throw some light on a possible cause (Port Forwarding and UPnP conflict)
    If just doing Port Forwarding the ports listed would have covered things (Except the Screen Sharing's random port)
    Regarding your latest post.
    I have  table similar to that on my Sagem 2504Fast Modem/router combined device and it too seems to list a different port on the external side on occasions.
    I would try the router with the Disable SIP ALG unticked (so it is not disabled). If the Help info on the right gives any info about what this Netgear version does it would be helpful.
    Some are like the Thomson-Alcatels I was talking about in that it points the SIP data to a specific place (Possibly a Phone socket on the device)
    Others seem to provide an "boost"  to enable SIP to work and don't seem to get in the way of iChat.
    Try adding the Names in Table 1 from this page and see if you can Video to those.
    There are 6 names in total (I am actually only seeing one on Line as I type)
