set ‘Auto Proxy Discovery’ from command line?

[mariac]

Hi,
I am putting together some ‘firstboot’ scripts and was wondering if there is a way to set the ‘Auto Proxy Discovery’ option under Mac OS X 10.6.x via the command line? Currently, I am using:

networksetup -setautoproxyurl “Ethernet” http://wpad.wpad.dat

But the above only sets the ‘Auto Proxy *Config*’ and does not do anything with ‘Auto Proxy Discovery’. Is it possible to set ‘Auto Proxy Discovery’ via the command line?

thx!
Maria

I too am looking for a way to check the “Auto Proxy Discovery” checkbox via the command line (for use with ARD).

Thanks!

Hi Guys.

I also have been looking for a solution to this. Unlike Mac OS X Lion, there is no command line that can configure this. In lion there is a setproxyautodiscovery flag as part of the networksetup command, this flag does not exist in 10.6.

I have developed an applescript that configures this. I intend to launch it an as app when the local admin logs in after a machine has been re-imaged. It configures the auto proxy discovery for both ethernet and airport.

It’s only a draft. It doesn’t open the system preferences padlock if it’s locked, this is possible, search google. Something like this could be used…

tell application “System Events”

tell application process “System Preferences”

tell window “Network”

if exists button “Click the lock to prevent further changes.” then

click (button “Click the lock to prevent further changes.”)

end if

end tell

end tell

end tell

If it runs twice, it will actually untick the auto proxy discovery, so it still needs some work, but it a start for those that are also having this issue.

Cheers Chris.

tell application “System Preferences”

activate

set the current pane to pane id “com.apple.preference.network”

get the name of every anchor of pane id “com.apple.preference.network”

reveal anchor “Advanced Ethernet” of pane id “com.apple.preference.network”

tell application “System Events” to tell process “System Preferences”

click (radio button “Proxies” of tab group 1 of sheet 1 of window “Network”)

click checkbox 1 of row 1 of table 1 of scroll area 1 of group 1 of tab group 1 of sheet 1 of window “Network”

Hi Guys.

I’ve had a lot of troubles to get this applescript/application to launch automatically for me, whether it be a login, logout or launch agent. It simply just doesn’t work, and I don’t think it’s really meant to anyway. Even embedding the applescript into a bash script, gave me applescript errors. As a stand alone application it does work – which is not feasible if you need to configure this for a lot of machines.

So I went back to the drawing board, and worked out that there is a key in /Library/Preferences/SystemConfiguration/preferences.plist called “ProxyAutoDiscoveryEnable” for each of the network services, that is present when the auto discovery proxy is active.

In order to script this, you have to work out the unique UUID for each network service, which is something like…

630A061A-7256-4631-9114-BECC6775B371

These values exist in the plist, you just have to “obtain” them and place them in an array for instance.

These values are unique for each network service and unique for each machine, hence why is has to be obtained, if you want to automate this and roll it out to a bunch of machines.

Using this unique UUID, then drill down into the plist file and add the “ProxyAutoDiscoveryEnable” key with a value of 1.

Straight away the Auto Proxy Discovery is active.

This script relies on the PlistBuddy command, to read (print), add and set the /Library/Preferences/SystemConfiguration/preferences.plist.

I understand the previous requests for this are over a year old. Yet some of us in the world are still having to manage and deploy Snow Leopard machines.

So if anyone would like to try out my script, please let me know.

Cheers Chris.

Hi mate, yea im in that boat, joined up pretty much to try out this script of yours! Any chance i could give it a shot?

Hi Brad. Sure.

I have it as a Launchdaemon that runs once at startup. Here is the script….

 

#!/bin/bash

# Mac OS X Build Environment
# Date: 06/2012
# Author: Chris Daley

# This script will configure the Auto Proxy Discovery, it applies to only 10.6.x machines.
# Unlike 10.7.x there is no flag for the command line networksetup to configure this. For
# 10.7 this is known as -setproxyautodiscovery

# The script generates the “ProxyAutoDiscoveryEnable” for each network service and configures it to 1
# In other words makes it active.

# Export Paths
# This is so we can use PlistBuddy

# why it has to be determined before we can continue.

for i in $(cat /Library/Preferences/SystemConfiguration/preferences.plist | grep /NetworkServices/ | cut -c 32-67);
do

# For each of the UUIDs, if it’s an Ethernet or Airport network service, then configure the Auto Proxy Discovery.

for x in $(PlistBuddy -c ‘Print :’NetworkServices:$i:UserDefinedName $_PREFERENCE)
do

case “${x}” in
Ethernet )

_CHECK=`PlistBuddy -c ‘Print :’NetworkServices:$i:Proxies:ProxyAutoDiscoveryEnable $_PREFERENCE 2>/dev/null | wc -l`

# If $_CHECK is 1 then we know the key “ProxyAutoDiscoveryEnable” exists. Lets just have a command that
# ensures it is the value of 1 anyway

if [ “${_CHECK}” -gt 0 ]; then

PlistBuddy -c “Set :NetworkServices:$i:Proxies:ProxyAutoDiscoveryEnable 1” “${_PREFERENCE}”

# If $_CHECK is 0 then we know the key “ProxyAutoDiscoveryEnable” does not exists. This would indicate that
# the proxy is not configured. So lets create the key and configure it to 1

else

PlistBuddy -c “Add :NetworkServices:$i:Proxies:ProxyAutoDiscoveryEnable integer 1” “${_PREFERENCE}”

hi, i am trying this, but i cant get it to work, any ideas ? – ive cut and pasted the code into a file, run it as su, i get several ” ” lines and thats it. first line is an error –

cp: “”/Library/Preferences/SystemConfiguration/preferences.plist””: No such file or directory

which i fixed by removing the “” from the _PREFERENCE and the cp lines.
