Hi,

I want to share a script with you I've just created.

You probably all are familiar when creating an base image on a Mac Pro and
image a MacBook Pro with it that the network service names are like
Ethernet 1, Ethernet 2 and FireWire. Ethernet 2 is actually the AirPort
(or Wi-Fi). The script I created renames the service to the hardware port
name if they do not match. After running the script on a MacBook Pro (with
10.6) the result will be: Ethernet, AirPort and FireWire.

#!/bin/bash

# renameNetworkServices.sh

# Script to correct the network services names after imaging a new machine

# Detect new network hardware
networksetup -detectnewhardware

# List all network services and read one by one
networksetup -listallnetworkservices | tail -n +2 | while read service
do # Check if network service is disabled (note the asterisk) if [[ ${service} == ** ]] then # Remove asterisk from string for renaming service service=echo ${service} | sed -e 's/.(.*)/1/' fi

# Use filter to select next line which has the harware port defined filter=false

# Display network services networksetup -listnetworkserviceorder | while read serviceorder do if [[ ${filter} == true ]] then # Grab hardware port hardwareport=`echo ${serviceorder} | sed -e 's/(Hardware Port:
//;s/, Device:.*//'` # Check if service name if different if [[ ${service} != ${hardwareport} ]] then # Rename the network service networksetup -renamenetworkservice "${service}"
"${hardwareport}" echo -e "Renamed network server "${service}" to
"${hardwareport}"" fi fi

if [[ ${serviceorder} == *${service} ]] then # Got the line with the service. Set the filter to true to
grab the next line which contains the hardware port filter=true else filter=false fi done
done

Have fun with it!

Kind Regards,

Martin van Diemen

I've played around with Martin's script and it didn't work like expected on Lion. (Especially the part to remove the asterix (*) when a network service is disabled)

After some changes in the code it's working now for me on Lion and Mountain Lion. I'm not sure if it's perfect what I've changed. I recommend to test it first. ;)

Thanks to Martin for the script.

#!/bin/bash

# renameNetworkServices.sh

# Script to correct the network services names after imaging a new machine

# Detect new network hardware
networksetup -detectnewhardware

# List all network services and read one by one
networksetup -listallnetworkservices | tail -n +2 | while read service
do

# Remove asterisk from string for renaming disabled services
service=${service#**}

# Use filter to select next line which has the hardware port defined
filter=false

# Display network services
networksetup -listnetworkserviceorder | while read serviceorder
do
if [[ ${filter} == true ]]
then
# Grab hardware port
hardwareport=`echo ${serviceorder} | sed -e 's/(Hardware Port: //;s/, Device:.*//'`
# Check if service name if different
if [[ ${service} != ${hardwareport} ]]
then
# Rename the network service
networksetup -renamenetworkservice "${service}" "${hardwareport}"
echo -e "Renamed network service "${service}" to "${hardwareport}""
fi
fi

if [[ ${serviceorder} == *${service} ]]
then

# Got the line with the service. Set the filter to true to grab the next line which contains the hardware port
filter=true
else
filter=false
fi
done
done
