Screen sharing access

Hi , I have found problems if I try to access my G5 (Screen Sharing) from my Macbook Pro . If I do not use or employ the Finder Sharing Icon , or the Finder's Network , I find the computer name , or iP4v address do not permit , allow , access in Screen Sharing . It might be safer to say the application doesn't recognise these as the correct question or the correct answer . I have read that the G5 optical card's physical limits are among the reasons I cannot venture to the Macbook's screen to verify a two way communication . Or to discover which address is the one that I am failing to select correctly with the aid of manipulating both computers . Any guesses advice scolds or anecdotal voyages ?

Hi tll123 , I have used that information , and I just tried it again . This is a paste of the data by the green dot with shy little ex's where there once was my addresses .
Other users can access your computer at afp://xxx.xxx.xx.x/ or browse for "Fxxxxxxxx Rxxxx Pxxxx’s Power Mac G5".
This is the dialogue from that effort .
Connection Failed
The server may not exist or it is not operational at this time . Check the server name or IP address and your network connection and try again .
OK
Here is another sequenced dialogue
Connecting To Server
The Finder cannot complete the operation because some data in afb://xxx.xxx.xx.x/
could not be read or written .
(Error code -36)
Try again cancel
I think we understand one an other what would you like clarified ?
Thanks for the Macworld article , I will read it after I make some coffee . Frederick

Screen sharing: can't access after update to SL

I have a set-up with a new mini server running SL Server 10.6.2. A Macbook Pro and iMac are on the network, they were both running 10.5.8. I manage my mini server with one of these computers through screen sharing.
I updated my Macbook Pro last week to SL 10.6.2.
I updated my iMac this week to SL 10.6.2.
I can't log in to my mini server from these 2 machines since the update. I get a message "Authentication failed, please verify user name and password".
I have restarted my imac under 10.5.8, and I can use screen sharing again to manage my server.
I am at a loss to figure why the update to SL on my clients has killed may screen sharing access to the server.
Any hints would be appreciated.

Screen Sharing with 10.4.11

I have been trying to share a 10.4.11 screen from a Snow leopard machine and have not been able to get it to work. Is it possible? If so is there DETAILED instruction of how do do it anywhere?
When looking at the other machine in Finder I see the sharing button but it won't connect for sharing (but can for file transfer)
My situation... I just got a 27" iMac running 10.6.2, but I still need to run some Classic Apps. I previously used a PowerMac G5 Running 10.4.11 which I passed onto another family member that still let me used Classic (which is why I did not upgrade it to 10.5)
I tried to get SheepShaver up on Running on my new iMac but only have a 9.1 Disk.
I have an older 800 MHz with 10.4.11 which can run classic.
Originally I had hoped to connect that to the video of the 27" iMac... But there are no adaptors and i read if and when they do exist they will be very expensive (this I did not know before I bought the imac)
Anyway one solution (outside of another monitor - not an option financially or space wise now) would be for me to be able to do screen sharing and control the PowerMac from the imac. That would let me use my classic Apps. I was thinking of connecting the machines via firewire 400 which I THINK should give reasonable performance (my router is only 100 Mbit)
Thanks

you need to enable screen sharing access on the 10.4 machine and possibly disable the firewall.
you should ask how to do that in the tiger forum, not here. once screen sharing is enabled you should be able to connect to the 10.4 machine from the snow leopard one simply by clicking on "share screen". no configuration at all is required on the 10.6 system. if anything needs to be done it will be on the 10.4 one. as i haven't used tiger in a couple of years can't give any instructions on that. this page seems to explain it
http://forums.macnn.com/90/mac-os-x/358759/screen-sharing-10-4-systems-leopard/
but as I said, ask on the tiger forum for best results.

ARD and Screen Sharing?

I want to be able to provide screen sharing access for my users when the connect via VPN however when I switch screen sharing on I can't use ARD to administer their machines.
Is there a way around this?

You don't/can't enable Screen Sharing when using ARD. When using ARD, screen sharing is handled by clicking the Remote Management box in the Sharing system preferences. You can't have one or the other.

Airport Extreme is allowing access to screen sharing, file sharing from external IP addresses (some from China, Canada etc)

How to get control over the ports/port forwarding etc in Airport Extreme?
How to make AE drop packets to certain ports from external ports. Or create whitelist/blacklists?
I figured out where the MAC filtering is! (It is inside the Timed Access Control). I wish it had a list of connected device and allowed me to select, name and add them.
I am getting requests from Chinese IP to the screen sharing ports forwarded to my iMac. Had requests to other ports as well. There was one IP address from CANADA too.
I want to open file sharing for local use only.

Why is Airport Extreme forwarding requests for screen sharing from external ip addresses to my imac? I don't have a public address, nor use dynamic dns service, and I have removed the server app (at least I think I have, but Apple Store doesn't think so).

Can't access iTunes and Screen Sharing sharing services on my mac Mini

Since several weeks now I face a networking issue of the stranger kind.
Currently I've got my Mac mini acting as the central server for music, photos and files in my home. Central Network Mgmt device is a Wireless Lan router.
In the past I was accessing the Mac Mini from my MacBook via Screen Sharing this doesn't work anymore. When requesting the service the connection effort just runs idle. In iTunes on my MacBook I can see the Libary of my Mac Mini iTunes but clicking on it brings the rotateing ball and after a certain while the message that the iTunes Libary is not responding and that I should check my Firewall settings. Which I did on both computers and they are wide open. 'Ipfw show' in Terminal brings back the message 'Open for any to any communication' also on both computers.
Makeing use of the File sharing service from the MacBook to the MacMini works but it takes a extreme long while until the shared folder appears on the MacBook.
Trying to access from the Mac Mini my MacBook for all these services is no problem.
One more thing is that my Mac Mini cannot access the Wireless Lan router anymore thru the Web Browser or thru a Ping. Here I get the message 'Ping Send to: permission denied'. I changed the Router still the same message. Internet traffic is only possible after I manually applied a DNS Server with its IP number.
Anyone out there who could help? I'm close to completely reinstall my Mac Mini but would naturally love to avoid this.

wireduck,
Highlight the music folder and on the keyboard type (Command) + i: on the window that opens scroll down if need and click on the lock on the bottom right. Type in an Admin User name and password. Then under the (Sharing & Permissions:) make sure the users you want to open the folder are listed and that there (Privilege) is set to @ least Read. If not hit the ( + ) sign and add them. After you have that all set up click on the little gear next to the ( - )s sign and (Apply to a enclosed items). that way each user can read the files. After that the little ( - ) sign should be gone on the folders.
Hope that helps.

Is there a way to access remote login and screen sharing logs?

I have a very high suspicion that my macbook air has been accessed through remote login. Here's what happened. I closed my macbook air, letting it sleep, and left my house. After coming back I found it logged into the Guest account (which I didn't know was enabled). Remote login, Remote sharing and file sharing were enabled but I disabled them. I can't remember enabling them but maybe I did.
I am also on a local network with about 8 other devices connected. I looked through /private/var/log/system.log but couldn't find anything concrete. I have yet to log out of the guest account and have connected to another internet connection just to be on the safe side.
My other user account is passworded and I could switch back to it from guest.
So if my macbook was accessed through remote login, is there a way to tell from what IP address it came from?
Please help me get to the bottom of this.

I guess if it did happen it would have said so. Thanks anyway.

HELP: Problem accessing host Mac MSL Mini using "Screen Sharing"

I have screen sharing enabled on my mother-in-law's Mac Mini so I can access it with Chicken of the VNC.
There are 2 user accounts, one Admin and the other regular. The problem is that when Chicken Of the VNC connects and I choose one of the accounts and log-in the connection terminates and I have to close Chicken of the VNC and re-connect.
Is there something in Sharing/screen sharing that needs to be set so the connection will not terminate when switching account .

If you can’t share computer screens
If you’re having problems sharing your screen with another computer, or sharing the screen of another computer, there are several things to check.
Here are things to try if you can’t share screens:
Make sure screen sharing is turned on and you have set up sharing permissions on the computer whose screen you want to share.
Sharing your screen with other computer users
If you’re trying to share the screen of another computer, open Sharing preferences on that computer and make sure you’re in the list of users who have been given permission to share that computer’s screen.
Make sure neither computer is in sleep mode. A computer can’t share its own screen or share the screen of another computer if it’s in sleep. Adjust the computer’s settings using Energy Saver preferences.
If you’re using Back to My Mac to share screens, make sure it’s turned on on both computers.
Sharing your computer’s screen using Back to My Mac
Make sure both computers are connected to the same network, or if you’re sharing screens using Back to my Mac, make sure they’re both connected to the Internet.

Mac pro cinema display cuts out and can't access Mac with screen sharing

Hi
A weird thing has started happening to my Mac Pro today. After using it for a few minutes the cinema display it is attached to on the Mac Pro just goes black. The Mac Pro is clearly still on - the light is on and i can hear the fans. The Mac Pro shows up on my local network and i can connect to it and access files from my Macbook, but screen sharing doesn't work (i just get the message 'contacting mac pro' and nothing else) and i can't connect to shared iTunes library either, which makes me think it is not just a display issue. I cannot wake the computer with the mouse or keyboard, which makes me think it isn't just a sleep issue. All i can do is physically turn the Mac Pro off, start it up and it will start up successfully and then work for a few more minutes before i get the same problem. I have reset the PRAM and SMC and still have the same problems. Can anyone suggest anything else i can try?
I should mention that i have another problem with the Mac Pro in that it has been spontaneously waking up from sleep and starting up from shutdown, and i still haven't resolved this. I don't know if it is connected to the above issue.
thanks
nick

I have experienced almost the exact same thing with my new 2008 Mac Pro and my 30" Apple display. It has happened to me twice in the last few weeks. The first time I chalked it up to a fluke, but now that it's happened again I searched the forums. In both cases I've had music playing in iTunes which continues playing, goes on to the next track, and so on. So the machine has not crashed in full. I too can connect to the files via another computer on the network, but cannot share the screen.
I have not had the sleep issues you have had.
I'll look at the link you provided in your next post to see where that gets me, but I wanted to let you know you were not alone on this one.

Screen sharing drive access problem

I have a Mac Mini I'm using as a media server. This mini has 2 hard drives and Mavericks installed in it. When I access the mini via screen sharing from my MacBook Air, if an no longer access the 2nd hard drive. It appears, and I can open the hard drive, but I can't access the folders on the hard drive. I can't access anything on that drive using applications, either.
This wasn't a problem using Mountain Lion. Any tips on how to fix this? All of my permissions are still set up correctly as they were before.
Thanks,
Bryan

Hey Guys,
I'm having this EXACT same problem, using this exact model of Belkin Wireless G Router: F5D7234-4 v4
We're both running the most current version of OS X, and when the user who is on the Belkin router plugs her MBP directly into her Comcast cable modem, everything works perfectly.
So given that the issue lies within the Belkin, I have remotely logged into the router and tried every possible combination of enabling and disabling:
- UPnP
- WMM
- Firewall
- QoS Monitoring
After doing this, we're still only getting audio whenever we try to screen share. As with the original post, we will start the screen sharing process, the window will say "starting screen sharing with....", but then we will only have audio.
Is my only other option to go through, set a static IP for this user, and setup all of the port forwarding per this article?

Thanks in advance for anyone's help!!

Accessing Muse via Screen Sharing has bizarre mouse behavior

When accessing another Mac using Screen Share... built in to the Finder, I can see Muse, but any attempt to edit a page displays strange mouse behaviour. Specifically, clicks down and up seem to be mis-interpreted as clicks held down by Muse, and only by Muse. Other apps don't show this behaviour. 100% repeatable, and easy to reproduce -- just click on an object and try to move it and you'll see how it's tough to unclick and stop dragging things around. Seems to be specific to Muse.
Using Lion on local machine, Snow Leopard on remote computer running Muse. Licensed on both locations, just sharing to give design advice.

See this at MacFixIt.
...and 'Google' for, say, "screen sharing black window" and you'll have some suggestions.

Can't seem to restrict access to screen sharing

I'm running a macbook pro (10.6.2). I'm at my folks' place for the holidays and I tried screen sharing into my MBP from my dad's iMac (10.6.2) and noticed that I could access the MBP screen without any password prompt.
I went into my MBP sharing system preferences and set screen sharing to: "Allow access for only these users: <my login>"
Again, I tried accessing my MBP screen from the iMac, and again I was able to get in without any password prompt.
Now I'm using my dad's login on his iMac, which is completely different from my MBP login which I thought I had limited screen sharing to. All of this is taking place within a home network.
I would like to allow screen sharing on my MBP, but only if it's password protected. Can anyone see what I'm doing wrong here? Why does my MBP keep allowing open access to screen sharing when it appears that I am restricting it to only my profile?
I tried messing with the options in "computer settings", but that didn't seem to help either.

I would suspect that the first time you did it (may have been a while back) the password was saved in your father's keychain on the imac.
open keychain access on the imac and see if it's there. if you delete the keychain entry for that password it should ask again next time you try to connect. and don't check the box to remember the password in the keychain.

Remote access without screen sharing?

I have an iMac and a MacBook Air. I'd like to remotely access the iMac from the Air on my local network, so I can take advantage of the iMac's superior processing power and file storage, while sitting in a different room. The problem is that my iMac has a 27" monitor and a 24" secondary display, so screen sharing doesn't work very well on my Air's tiny 13" monitor.
My question is, is there any software that would allow me to remotely login to the iMac and give me a Mac OS interface, but size that interface appropriately for the MacBook Air, rather than just showing me the actual desktop of the iMac. Basically, I want it to pretend like the notebook's monitor is the monitor connected to the remote mac and still execute all the code on the remote mac. Extra points if I can essentially instantiate a second instance of the same account on the iMac, so I can be logged in locally and remotely at the same time, with the same account, but with different looking desktops.

I presume that your issue is your viewing two very small side-by-side screens on an already small screen. There is a drop down menu on the screen sharing window itself (that is, the window of the screen sharing app running on the MBAir, on the left side in the vicinity of the toolbar) where you can select to display either the left screen, the right screen, or both screens. I have a (employer-owned) 17" MBP that accesses a (employer-owned) dual-screen iMac and find that switching between left and right screens is not too bad of a compromise, in exchange for being able to actually see (and do) anything on the iMac from the MBP's screen sharing app.

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.

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.
