How to skip OS X VNC connect password requester?

Question

I have an Ubuntu server which I tend to use via VNC from OS X. For this, I have saved a .vncloc file from the built-in Screen Sharing client. When I click this icon, Screen Sharing connects to Ubuntu, but shows this requester already filled in:

Since I saved my password in my Keychain, I just have to press enter every time. Is it possible to skip this requester somehow and connect immediately using the saved credentials?

Answer 1

The questioner already has a .vncloc file, so the simplest answer is to add the username into that file:

• Locate the file.  (If you haven't moved it, it'll probably be in ~/Library/Application Support/Screen Sharing/.)

• Ensure you have write permission.  (E.g. with the Finder, or chmod +w.)

• Open it in your favourite text editor (e.g. vim).

• Edit the first line with vnc://<address> to read vnc://<username>@<address>.

• Save it.

The file will then connect directly to the remote system, skipping the password dialog entirely.

You can run it by double-clicking on the file in the Finder, dragging the file onto the Dock, or using open from the command line.

(Alternatively, you can include the username in the vnc: address when first creating the file.)

Answer 2

Applescript. Enable Accessibility when prompted.

do shell script "open vnc://username@thisaddress:portnumber"

tell application "System Events" to tell application process "Screen Sharing" ¬
to tell window 1 to click (first button whose name is "Connect")

Use Automator to save the script as an app.

Unfortunately following solution won't work for Ubuntu, but when dealing with Macs, here is what I did to get 1 click connection available on the Dock

1. Shared target computer in iCloud "Back to my Mac" section
2. Connected to that computer, by clicking "Share Screen" button in the Finders "Shared" section (that way it doesn't ask password when connecting, since it connects by iCould id, instead of ip)
3. Created iMac.vncloc shortcut by dragging icon from Screen Sharing title bar (When saving shortcut from iCloud based session, shortcut doesn't ask for password either)
4. Created Automator app "iMac", that runs shell script "open /Users/dmatora/Desktop/iMac.vncloc"
5. Added "iMac" app to the Dock

Answer 4

Open Safari and type in the url:

vnc://username:password@thisaddress:portnumber

If you don't want the password just omit it, like this:

vnc://username:@thisaddress:portnumber
