I use the built-in VPN on Mac OS X 10.7.3. It's IPSec, FWIW. From time to time, it disconnects (probably an issue with my corporate server). Is there a way to get it to automatically reconnect? Sometimes I don't notice for a while, which is kinda annoying.
You could use the following AppleScript, save it as an application and set it to be a agent (no dock icon).
This script will setup a VPN connection when there is none. Therefore, it should also reconnect shortly after your connection drops. You can change the interval to check your VPN connection, it's 120 seconds in the script.
I've explained how to set this up in this answer.
I made some changes to the provided answer, because if something is worth doing it's worth doing into the ground. I wanted to reconnect if the VPN was dropped, but NOT reconnect if the VPN was intentionally disconnected. The solution I came up with was both effective and inelegant.
First I added hooks to the pppd startup and shutdown to keep track of the desired VPN state. These files should be owned by root, and have world read/execute permissions (
/etc/ppp/ip-down: for OS X 10.9.5 and below
/etc/ppp/ip-down: for OS X 10.10 and above
Then by modifying the AppleScript above, I was able to check the '/var/run/reconnect_vpn' status variable to determine whether to bring the VPN back up:
As before, change the line
I have a feeling that if you're the kind of person is this particular about VPN behavior, then you're also the kind of person who likes fumbling around until you find a solution and therefore this answer has no audience. But just in case, here it is. Hope it helps somebody.
There's an app that does it called VPN Auto-Connect (Mac App Store link). It's $0.99.
Once started, it lives in your menu bar; when you use it to turn VPN "on", it will monitor a VPN connection profile you set up in OS X's Network preference pane and ensure you always remain connected to it. VPN Auto-Connect's menu-bar icon provides a list of all the VPN connections you've defined and lets you choose which one to always connect to.
We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.
A new option is VPN Monitor available on the AppStore. It allows for more customization, like auto-login, cycling through VPN connections, etc. At least OS X 10.9 Mavericks required.
Script auto-reconnect any dropped VPN service.
I had been using rjarvis2010's solution but I wasn't quite happy with it.
I have many different VPN services I connect to, so I wanted a script that would automatically reconnect any VPN I was connected to.
To make it work for you, you need to replace
Once you're done, save it as an application and place it in your Login Items and you're good to go.
Also, and this is important, you need to set up the PPP hooks as described in rjarvis2010's solution
Also, I would recommend you don't try this connecting multiple VPNs simultaneously. To stop this script you might need to force quit it through the activity monitor (as the repeat loops don't allow it to receive external input at times).
I'm using different approach to keep my VPN connection alive.
This involves getting a very simple
and enter following content :
You can use following command to start your daemon and test:
This way, you have a daemon running for all users, connection attempted only when internet connection is available. Also, VPN is reconnected automatically when internet connection is back…
I find this method the most robust as it allows a vpn connect to be made automatically, before a user logs in (useful for servers).
Updates for Yosemite (OSX 10.10)
Is depreciated in Yosemite. You can use the following instead
No longer works in Yosemite. You can use this instead
The beauty of AppleScripts is that you can do almost anything with it and it's free, the downside is that they are usually not very responsive (polling at a fixed time interval) and lack features only native MAC OS X apps can have. A nice and new VPN auto reconnect app is "VPN Monitor" in the app store, it reconnects instantly the moment a VPN connection drops, is able to reconnect to a different VPN service if the preferred service is down, connects at start-up, keeps track of your downtime and uses a minimum of system resources to run in the background as a statusbar application.
