We found that some of the mac users in the company are using google dns and we would like to set everyone's dns to our dns. Is there a script we can push out via jamf to set DNS on all our macs including wifi/ethernet?

Thanks

    Here's a script I use. I haven't done much with it lately, but I think it still gets the job done.

    #!/bin/bash

NetworkServices=`networksetup -listallnetworkservices`

if [[ $NetworkServices =~ "Wi-Fi" ]];then
    networksetup -setdnsservers Wi-Fi empty
    echo "Reset DNS Servers for Wi-Fi"
fi

if [[ $NetworkServices =~ "Ethernet" ]];then
    serviceName=`networksetup -listallnetworkservices | grep "Ethernet" -m 1`
    networksetup -setdnsservers "$serviceName" empty
    echo "Reset DNS Servers for $serviceName"
fi

if [[ $NetworkServices =~ "LAN" ]];then
    serviceName=`networksetup -listallnetworkservices | grep "LAN" -m 1`
    networksetup -setdnsservers "$serviceName" empty
    echo "Reset DNS Servers for $serviceName"
fi
