OpenSSH with Mac Keychain

[Chao-Chin Yang]

Hi,

I am running into an issue with OpenSSH which does not remember the passphrase of my private key.

When I ssh to a remote host using public/private key authentication, a dialog box asking for the passphrase pops up.  I enter the passphrase *and* tick the box to ask Keychain to remember my passphrase.  After that, I can successfully log into the remote system, but there is a message: "Could not add identity: /Users/my_username/.ssh/id_rsa”.

I can continue to log into the remote system without entering again the passphrase.  However, once I completely log out of my Mac and re-log into my Mac, the terminal does not remember my passphrase anymore.

After googling around, it seems that the Mac native SSH has added a new SSH keyword “UseKeychain”, while the MacPorts version does not have this keyword and is having problem talking to Keychain.  I cannot find any solution to this.

Does anyone know any solution or is working on one?
