Hi all,

at my client we have a zoo of MacPro's Ethernet , MacBooks with Thunderbolt-Ethernet and Thunderbolt-Displays.

While we're upgrading the Macs to latest Yosemite (ElCapitan is not an option because of the productive environment), clients often "forget" the Network-Settings (DNS-Servers and Proxy).

Normally, we have three locations:

Client_Net:
Only Ethernet, Thunderbolt-Ethernet or Display-Ethernet enabled
Special DNS and Proxy

Client_WIFI:
Only WIFI enabled
Special DNS and Proxy

WIFI-Free
Any Adapter can be active and can be used (WIFI, Thunderbolt-Ethernet,...)
No special settings.

My question:

How to put it with "networksetup" into a script that these networksettings/locations are with a firstboot-script are enabled again?

Thank you!
Holger

Hi Holger,

here's a redacted version of the networksetup script i use,
you may be able to adjust it to your needs:

Depending on in which scenario you use it, it might be useful to blow away any locations that existed previously before running this (or add a couple lines to the beginning to take care of this)

    Thanks Chris. Used your script as reference and created this per our needs. Enhanced a bit to eliminate hardcoding of Network Adapter information.

    #Proxy Information. Input your proxy information here.
proxy="proxy.domain.com"
port="1234"
bypass="domain1.com, domain2.com, *.domain.com"

#Detect existing Network Adapters and store in an array
detectadapters=$(networksetup -listallhardwareports | grep "Hardware Port" | sed 's/Hardware Port: //g' | grep 'Wi-Fi|Ethernet|USB|LAN')

IFS=$'
'
netadapters=($detectadapters)
unset IFS

#Check if Network Locations are already existing and remove them
work=`networksetup -listlocations | grep "Work Networks"`
nonwork=`networksetup -listlocations | grep "Non-Work Networks"`
automatic=`networksetup -listlocations | grep "Automatic"`

if [ "$automatic" != "" ]; then
networksetup -switchtolocation "Automatic"
else
networksetup -createlocation "Automatic" populate
networksetup -switchtolocation "Automatic"
fi

if [ "$work" != "" ]; then
networksetup -deletelocation "Work Networks"
fi

if [ "$nonwork" != "" ]; then
networksetup -deletelocation "Non-Work Networks"
fi

#Setup Network Locations
networksetup -createlocation "Non-Work Networks" populate
networksetup -createlocation "Work Networks" populate
networksetup -switchtolocation "Work Networks"
networksetup -deletelocation "Automatic"

# Configure Proxy Looping through the available network adapters
for i in "${netadapters[@]}"
do
networksetup -setwebproxy "$i" "$proxy" "$port"
networksetup -setsecurewebproxy "$i" "$proxy" "$port"
networksetup -setproxybypassdomains "$i" "$bypass" 
done

exit 0

    Any suggestions for further enhancement are Welcome.
