Hey guys and gals we have a 100basetx Full-Duplex setup here and cannot leave the adapters on automatic. I concocted a pretty amateur script full of if statements; it works but I am sure someone can help me clean it up with a case statement or something like that.



#!/bin/sh

# Declaring Variables



en=`/usr/sbin/networksetup -listallnetworkservices | grep -x "Ethernet"`

en1=`/usr/sbin/networksetup -listallnetworkservices | grep -x "Ethernet 1"`

en2=`/usr/sbin/networksetup -listallnetworkservices | grep -x "Ethernet 2"`

thunderbolt=`/usr/sbin/networksetup -listallnetworkservices | grep -x "Thunderbolt Ethernet"`

usb=`/usr/sbin/networksetup -listallnetworkservices | grep -x "USB Ethernet"`

display=`/usr/sbin/networksetup -listallnetworkservices | grep -x "Display Ethernet"`



# Setting Devices



# Setting Built-in Ethernet



if [ "$en" = "Ethernet" ]; then

    /usr/sbin/networksetup -setMedia "Ethernet" 100baseTX full-duplex

    echo "Built in Ethernet Completed"



elif [ "$en" = "" ]; then

    echo "No Devices Found"



fi



# Setting Built-in Ethernet 1



if [ "$en1" = "Ethernet" ]; then

    /usr/sbin/networksetup -setMedia "Ethernet 1" 100baseTX full-duplex

    echo "Built in Ethernet 1 Completed"



elif [ "$en1" = "" ]; then

    echo "No Devices Found"



fi



# Setting Built-in Ethernet 2



if [ "$en2" = "Ethernet" ]; then

    /usr/sbin/networksetup -setMedia "Ethernet 2" 100baseTX full-duplex

    echo "Built in Ethernet 2 Completed"



elif [ "$en2" = "" ]; then

    echo "No Devices Found"



fi





# Setting Thunderbolt Ethernet



if [ "$thunderbolt" = "Thunderbolt Ethernet" ]; then

    /usr/sbin/networksetup -setMedia "Thunderbolt Ethernet" 100baseTX full-duplex

    echo "Thunderbolt Ethernet Completed"



elif [ "$thunderbolt" = "" ]; then

    echo "No Devices Found"



fi



# Setting USB Ethernet



if [ "$usb" = "USB Ethernet" ]; then

    /usr/sbin/networksetup -setMedia "USB Ethernet" 100baseTX full-duplex

    echo "USB Ethernet Completed"



elif [ "$usb" = "" ]; then

    echo "No Devices Found"



fi



# Setting Display Ethernet



if [ "$display" = "Display Ethernet" ]; then

    /usr/sbin/networksetup -setMedia "Display Ethernet" 100baseTX full-duplex

    echo "Display Ethernet Completed"



elif [ "$display" = "" ]; then

    echo "No Devices Found"



fi


Basically what I am trying to do is set all the adapters to 100basetx Full-Duplex. What would be even cooler would be a way to detect which adapter is currently active that way if someone takes their laptop home they can be at auto and when they get back to the office and login it could reset back to 100basetx Full-Duplex.



Any opinions welcomed!

This worked with just ethernet. Haven't tested with all the other devices.



#!/bin/bash



SERVICE_GUID=`printf "open

get State:/Network/Global/IPv4

d.show" | scutil | grep "PrimaryService" | awk '{print $3}'`



SERVICE_NAME=`printf "open

get Setup:/Network/Service/$SERVICE_GUID

d.show" | scutil | grep "UserDefinedName" | awk -F': ' '{print $2}'`



if [ "$SERVICE_NAME" = "Wi-Fi" ]; then

    echo "User on Wi-Fi"

    exit 0

elif [ "$SERVICE_NAME" != "Wi-Fi" ]; then

/usr/sbin/networksetup -setMedia "$SERVICE_NAME" 100baseTX full-duplex

    echo "$SERVICE_NAME Completed"

fi


The first part to find the current active device comes from

I have not tested this at all, so make sure you do before deploying it. Also, as written, it makes the user unable to ever set their network service to anything other than "100baseTX full-duplex" while on the network, and unable to ever set it to "100baseTX full-duplex" while off network. Keep that in mind.

Edit: Copied/pasted some parts from an old script. Removed some bits that didn't apply to this one.

Very nice!!!! Worked when plugged in to Ethernet. Unplugged and plugged in TB Ethernet and viola!

Here's my modification, which sets Ethernet to autoselect and disables all other network interfaces. This is handy if you have assorted Mac models with different interface names. I didn't include 'Firewire' since I don't have any, but you could add that.



#!/bin/sh



# Setting Devices



# Set Built-in Ethernet to autoselect



if [[ `/usr/sbin/networksetup -listallnetworkservices | grep -x "Ethernet"` = "Ethernet" ]]; then
/usr/sbin/networksetup -setMedia "Ethernet" autoselect
echo "Built in Ethernet Completed"
fi



# disable Thunderbolt Bridge



if [[ `/usr/sbin/networksetup -listallnetworkservices | grep -x "Thunderbolt Bridge"` ]]; then
/usr/sbin/networksetup -setnetworkserviceenabled 'Thunderbolt Bridge' off
echo "Thunderbolt Bridge Completed"
fi



# disable Bluetooth DUN



if [[ `/usr/sbin/networksetup -listallnetworkservices | grep -x "Bluetooth DUN"` ]]; then
/usr/sbin/networksetup -setnetworkserviceenabled 'Bluetooth DUN' off
echo "Bluetooth DUN Completed"
fi



# disable Bluetooth PAN



if [[ `/usr/sbin/networksetup -listallnetworkservices | grep -x "Bluetooth PAN"` ]]; then
/usr/sbin/networksetup -setnetworkserviceenabled 'Bluetooth PAN' off
echo "Bluetooth PAN Completed"
fi



# disable Wi-fi



if [[ `/usr/sbin/networksetup -listallnetworkservices | grep -x "Wi-Fi"` ]]; then
/usr/sbin/networksetup -setnetworkserviceenabled 'Wi-Fi' off
echo "Wi-Fi Completed"
fi
/usr/sbin/networksetup -listallnetworkservices
