I upgraded to OS X 10.7 this morning and upon attempting to connect to my corporate VPN, I discovered that my script at /etc/ppp/ip-up has disappeared. Has anyone else encountered this problem, or do you know where it might have ended up?

  • If you grab a copy from your backup, does it still work for you? – bmike Jul 20 '11 at 21:33
  • I'm ashamed to say that I made major changes to the file since my last backup and didn't back up prior to the upgrade. – Ryan Tenney Jul 20 '11 at 21:38

    Oh no! Yikes - at lest you know a little about changing it. I feel a little bad for asking - hope it gets sorted out for you or someone here has a copy they can share. I would try entering anything in VPN software and see if it still creates a new script that you can start with. – bmike Jul 20 '11 at 21:48

    Still happening in Yosemite - upgrading from 10.10.0 to 10.10.1 nuked mine (again) – CupawnTae Dec 2 '14 at 14:32

It very likely got overwritten. The upgrade does nothing to back up what it considers "system files" and simply overwrites them with the latest version.

Another good reason to do a full backup before upgrading.
