REPLAY: Mac OS X and Native SSH-Agent Notifications

Having recently updated my 2014 Macbook Air 11″ from Mac OS X 10.10 to 10.10.4, I lost my customizations to Apple’s OpenSSH and no longer was I receiving anything in the Notification Center for SSH logins using my keychain. Looks like it’s time to rehash the steps necessary to reload support for the Notification Center for those going through the same ordeal.

For reference here’s the original blog post where I introduced the customizations required to get Apple Notification Center support for OpenSSH on Mac OS X:

Step-by-step we’ll go through the motions of re-obtaining the latest copy of Apple’s modified OpenSSH, to be patched.

NOTE: Make sure you’ve updated Xcode in Apple Software Update, else you’ll get the error "configure: error: Your OpenSSL headers do not match your library" during compilation steps below.

ASIDE: You can browse Apple’s opensource repository at (obtaining the latest copy of OpenSSH with Apple’s customizations couldn’t be easier). Rather than documenting how to navigate said page, below steps will instead use direct links to the software we’re recompiling (for brevity).

How to patch Apple’s OpenSSH to support native Mac OS X Notification Center (in 13 easy steps):

  1. Open
  2. curl -LO
  3. tar zxf !$:t
  4. cd !$:r:r/openssh
  5. curl -L -o patch.txt
  6. patch -N < !$
  7. ./configure --with-pam --with-audit=bsm
  8. make
  9. sudo cp -avf /usr/bin/ssh-agent{,.orig}
  10. sudo cp ssh-agent /usr/bin/ssh-agent
  11. killall ssh-agent
  12. ssh some-host
  13. Click "Always Allow" to confirm access from new ssh-agent to Keychain

Now every subsequent ssh request will give you a notification in Apple's built-in Notification Center. Cheers!
