Screen Sharing How?

[krewelement394]

Ok, I am trying to enable screen Sharing between my tow Macs. my iMac and my Macbook. i see the "share Screen" button when i click on my imac/macbook in finder on the left side corner. I am asked for a password and a username... what username and password is it asking for? i typed in my macbook's login name and password, imac's login and password, and my e-mail and password (bassically the username for my internet provider)

i need help, i googled this but i can't find the answer to my question. i Youtubed this but all i got was a lot of info on what screensharing is, i know what it is, i want to be able to use it....

-Thanks!

Assume you want to do some work on a remote Mac via 10.5's Screen Sharing, but you forgot to enable Screen Sharing before you left the remote Mac. You're now a good distance away, and apparently stuck. Fortunately, because the screen sharing system uses launchd to monitor its state, enabling and disabling is as simple as adding a file in the remote Mac's /Libary/Preferences folder. (Note that you'll need to be able to login to the remote Mac via ssh to run these commands on that Mac.)
$ cd /Library/Preferences
$ echo -n enabled > com.apple.ScreenSharing.launchd
To disable screen sharing:
$ cd /Library/Preferences
$ rm com.apple.ScreenSharing.launchd
If you have a Finder window open with the remote Mac selected in the Shared section, you'll even note the icon for Screen Sharing coming and going as you do this. dont copy the $

i dont have neither of those files.

i actually managed to login in for a couple of minutes, but i accidently clicked on a setting, and it logged me out. ok my next question is, can i use screen sharing outside my home, without using ichat, like me being at school and my imac at home lol duh? or do i have to be on the same network for it to work?

If both computers are connected to the internet and Screen Sharing is enabled on one of the machines then you should be able to see that machine's screen on the other machine.

Please do some reading. There must be dozens of articles about Screen Sharing in OS X that a simple search will find for you.

Did not answer my question... I asked if the computers have to be connected under the same network in order for screen share to work. can i use my school's internet and still be able to access my imac using screen sharing? or does it have to be same network?

I use iChat for remote screen sharing where the other computer is hundreds of miles away and certainly not on my network.

It's not terribly fast and someone has to be at the machine to allow screen sharing, but if you can arrange that you should be in business.

I haven't tried any VNC-style sharing across network boundaries but as long as all of the ports are passed between the networks, it should work. You may need some port forwarding done on the home routers if you have NAT enabled.

Let me keep this simple.

No, the computers don't need to be on the same network.

thanks exactly what i was looking for

yeah i know about ichat, i was trying to go around that because no one else uses my iMac but me and really no one is home.

OK so is VNC something i have to enable, install or what? and is NAT the same as VNC? im confused...

This will get it done for basic purposes. This will work for older macs running tiger as well.

If you've enabled screen sharing on the imac at home, then in theory you can connect to that machine from your MacBook using the vnc protocol over the internet. No additional installation or enabling is required. You need to use a vnc client on your MacBook to communicate with the iMac. One such client should already be present on your MacBook. It's the Screen Sharing app located in /System/Library/CoreServices. (And it's free.)

Again, I urge you to do some reading.

How do the machines remember each other when they are off network?

I thought screen sharing like that was only possible with MobileMe.

Not sure what you mean. You give one machine the other machine's ip address and contact is made.

^^ if you redirect traffic on the necessary ports correctly, you can access that machine using its external ip address via VNC on another computer. I've done it before and it works, but if you're assigned a dynamic ip from your ISP, be sure to make sure you have the current address before trying, otherwise you'll end up pulling your hair out .

i tried it using the Screen Sharing...didnt work i went to starbucks today and i took my macbook, but no luck. i used the chicken app and it worked! not sure exaclty what i was suppose to put...was it my imacs ip adress or it's name...?:O

Ok i know this is off topic, but it relates in a way. i have an external drive connected to my imac, when i access it owith my macbook it appears on the desktop. i open time machine and i can use the air shared external drive to backup my macbook, but once i close my connection, such as shuting down etc., i try backing up my macbook with the external drive connected to my imac (same one), it backs up; however, the backup starts over as if it never happened the first time...:/ can i the drive stay with time machine? or does that only work with a time capsule? if i have an airport express, can i connect my external drive via usb?

I was referring to the "back to my mac" feature of mobile me. It adds all synced machines directly to your finder's sidebar and you can initiate a connection and share screen easily (as well as copy/paste files, print, etc). No one needs to authorize a ichat session, no ports to mess with. I thought what was suggested at the top of this post was that this was possible without mobileme.
