.bat conversion

All this does is change the default route in your network settings. You could do that by hand. It is the one called 'router'.



This shows you how to access the network preferences with Applescript, it should get you started

Scriptbased interacting with a GUI is hard.

show wich default route is used:

Code:

route get default

change to the one route:

Code:

route change default 172.20.1.4

change to the other route:

Code:

route change default 172.20.1.254

You could use '-net 0.0.0.0 0.0.0.0' of '-net 0.0.0.0/0' or even '-net 0/0', but 'default' is just as clear.

There are some other changes needed, but none major.

The other point is: is there a willingness to resolve this for the whole company? A cheap router with two WAN-ports can do this automagically for everybody.

 

Are you root on your machine ?

I agree with a previous poster above - a simple WAN router with failover could solve this for the whole company without even anyone noticing.

Anyways, been looking into writing a tiny python script for this and using Platypus (google for "platypus mac" to create a program out of it - but from testing the route command it seems you must be 'root' to do the change.

And Platypus says it can run with admin privileges, but that this not the same as root. Maybe it'll work, maybe it won't.

Here's at least an app that will show you where the default gateway is currently pointing to... it'll run in your top menu bar and when clicked on will show you the extremely useful message of your ip address and what interface it's on.

It works on my mac mini (latest Mac Os, Python 2.7 which is installed by default on all macs so should not be a problem). But YMMV.

Good luck !

 

Try this little script

@burne : Thank you for the commands.

@drewbuchman : Looking at your .bat file I guess goto RouteT1 must be goto RouteCbeyond or maybe it's a typo. The script should get you going writing your own. As it is your mac i'm also guessing you have an administrator account because the script will ask for your credentials. Please forgive me if I've made any mistakes as I'm not a native English speaker.

Run this in Scripteditor :

Code:

display dialog "Show or Change Default Route" buttons {"RouteT1", "RouteDSL", "RoutePrint"} default button 3
set the button_pressed to the button returned of the result
if the button_pressed is "RouteT1" then
	-- action for 1st button goes here
	set RouteT1 to do shell script "route change default 172.20.1.254" with administrator privileges
	display dialog RouteT1
else if the button_pressed is "RouteDSL" then
	-- action for 2nd button goes here
	set RouteDSL to do shell script "route change default 172.20.1.4" with administrator privileges
	display dialog RouteDSL
else
	-- action for 3rd button goes here
	set RoutePrint to do shell script "route get default | grep gateway"
	display dialog RoutePrint
end if

 

Nice to hear it worked. Thank you for the feedback. If you don't want to see the dialog box asking for your password you can add it to the script like so :

set RouteT1 to do shell script "route change default 172.20.1.254" user name "your username" password "mypassword" with administrator privileges

Only do so if you're the only one with access to your mac as it exposes your credentials to anyone who edits the script.

Happy scripting.
