I recently did a clean install of Mavericks, and ever since I have, I've been having intermittent DNS lookup failures on the terminal only. Browsers work fine (Chrome, Safari).

But nothing works from the command line (ping, tracert, curl, git clone, etc.). The problem will eventually just go away (sometimes 30 seconds, sometimes 10 minutes), and it does help to switch between the network and the guest network (running a 2 year-old Apple Airport Express), but the problem will eventually express on either connection. It's maddening.

It seems bizarre that the problem is restricted to the terminal; it seems like network requests from the terminal would use the same mechanism as a browser.

  • OSX 10.9.4
  • Chrome 35
  • Safari 7.0.5
  • git 1.8.5.2
  • curl 7.30.0
  • could you share your Terminal commands you use, and if you get error messages ? – Ruskes Jul 16 '14 at 7:52
  • I can do that when I get home. The commands are all very mundane: git clone https://github.com/georgepaterson/jquery-videobackground.git, ping google.com. The error messages are all along the lines of "Unknown host: github.com" or "Couldn't reach google.com". – Ethan Brown Jul 16 '14 at 15:00
  • I just upgraded to Mavericks and am having this same issue. It's true in other apps like iTerm as well so I assume it's an issue with some core service/library. – aezell Nov 14 '14 at 15:52
