allenm: you can change the ssh command to
ssh username@ip_address_or_hostname -L 5901:localhost:5900 in which case you would connect using :1 instead of :0. If the command line scares you, or if you just have trouble remembering the syntax, SSH Tunnel Manager for the Mac will generate the SSH command for you. It’s what I use. Adding a -C to the command line will also compress the SSH tunnel.

xioni: it sounds like you’ve got too many files open. This is something that can be overridden in the terminal, but it can be somewhat dangerous. If you want to know more, try searching for ulimit.

How do you deal with a situation where you have more than one remote machine to which you wish to connect? At this point it looks like localhost will always go to the same remote machine.

Is there a way to compress the data sent via Apple’s screen sharing app? I know VNC servers can compress the data, and I’m interested in anything that makes the interface snappier.

many thanks for this description.

i am finding an error occasionally occurs on in which in the terminal window. basically it returns ad infinitum

“accept: Too many open files”

Anyone know what causes this problem? Any ways to handle it?

Thanks

@Justin – the username and password that work for me are the user login for an account on the host (remote) machine.

It appears that the VNC password setting is somehow non-active in this configuration for me — that is, no matter what the setting in System Prefs, it will never be honored.

I can’t figure out what username and password to put in when screen sharing prompts me… any help?

The connection to the remote machine is working, but every time I hit connect button the pop-up window tells me that VNC server does not support encryption. Disregards of how I set up Screen Sharing preferences I still have this window. I connect from mac to mac. Is it possible to block it somehow?
Best regards
Leonid

So wait, let me get this straight- you disable Kerberos, the screen sharing app’s encryption, and then set up an ssh tunnel? What’s the point? I mean, unless you’re blocking all connections other than the ssh connection, you’re not any more or less vulnerable after this. 5900 and 88 are perfectly fine as long as you’ve got everything encrypted. All you’re gaining here is speed, not more security.
