Unable to Launch Tunnelblick - Yosemite 10.10

[nicholas...@points.com]

Hey everyone,

Up until recently one of my users has been happily running Yosemite and Tunnelblick. When out of no where Tunnelblick stop working(launching).

I've tried to uninstall(using the uninstallation tool) and reinstall using the latest(3.4.3) downloaded from code.google.com to no avail.

When trying to reinstall the software nothing appears on screen after mounting and double clicking the installation icon.

Digging into the logs I found this in the system.log:

Mar  3 15:14:31 THISCOMPUTER.local Tunnelblick[1324]: An uncaught exception was raised

 Any suggestions? I really don't want to have to find another OpenVPN client for my users :(

Thanks,

The only thing I can think of is that the latest update to Yosemite is disallowing the use of /tmp.

Could it be that the user is not an admin user? Perhaps that has something to do with it. The "error 13" may be an access denied error.

I just started a one-week holiday, but if when I have time I will look into using something other than /tmp. (For the purposes of this, it doesn't really matter much what the "working directory" is; Tunnelblick just sets it to /tmp so it is set, rather than leaving it to whatever the default is (which isn't documented)). If I can do that, I will post on this thread and be able to provide a "snapshot" (pre-release version of Tunnelblick) that uses something other than /tmp, so you can see if that solves the problem.

A quick look at the code shows that /tmp is used in several other places for different purposes, and some don't allow the standard user's temporary directory because the pathname for that is too long (it has a UUID-like component). So it may be difficult to fix this problem if it is really that Yosemite isn't allowing standard users to use /tmp.

It would be helpful to know if an admin user on the same machine has the same problem.

Hey jkbull, thanks for the quick response. I attempted the same uninstall, reinstall steps I mention in my original post with the admin account..

OK, thanks for trying it in an admin account.

Is there any extra security software installed on this computer (antivirus, etc.)?

Can you tell me exactly what version of Yosemite is being used, including the build number?

(To get the build number, click the apple icon in the upper-left corner of the display, then hold down the "Option" key and click "System Information", then in the new window, click on "Software" on the left side. There should be a "System Version" entry on the right side, which includes the build number. On the Mountain Lion system I'm using right now, it is "System Version: OS X 10.8.5 (12F45)", so the build number is 12F45.)

We do have Symantec AV running, but this user is the only one having this issue. The laptop is running 10.10 (14A389).

[jkbull...gmail.com]

OK, thanks. I can't test that version of Yosemite until I get back to my regular development system next week.

But since this has to do with access to /tmp, you might want to compare the ownership/permissions on the problematic computer and on a working computer with the same version of Yosemite.

It is possible that a "Repair Permissions" (in Disk Utility) would fix any problems, but you might need to fix them manually.

On my 10.8.5 system, /tmp looks like this:

$ ls -l -@ /

...

rwxr-xr-x@  1 root             wheel       11 Sep  8  2013 tmp -> private/tmp

com.apple.FinderInfo     32 

and /private looks like this:

$ ls -l -@ /private

total 0

drwxr-xr-x  104 root  wheel  3536 Mar  4 09:15 etc

drwxr-xr-x    2 root  wheel    68 Jun 20  2012 tftpboot

drwxrwxrwt   11 root  wheel   374 Mar  4 10:06 tmp

drwxr-xr-x   27 root  wheel   918 Dec 18  2013 var

This right here, when I ran the Repair Permissions - Repairing permissions on /tmp was the first item that popped up.

JkBull, you da man. Fixing stuff while on vacation! 

I can't thank you enough!
