macOS Login/Logout Script

[xfallen86]

Hi everybody,
First, thanks for the job done on that forum !!

I'm an IT specialist and I manage a hundred of iMacs with 10.12 installed. I have to log when user login and logout with the Mac address and IP address.

Have you an idea if I can do a script which is saved automatically on a shared point with each information when user login and logout of a computer ?

Have a good day.

Depends on what kind of sollution you want.
You might consider to write a small application 'background' application with xCode.
Register it to launch in LaunchDaemons

On applicationDidFinishLaunching you can log NSUsername() as being 'logged in' on IP: [[[NSHost currentHost] addresses] lastObject]
afterwards call [self LogoutNotifications];
The function might look something like this

-(void)LogoutNotifications {
   NSNotificationCenter *notCenter;
    notCenter = [[NSWorkspace sharedWorkspace] notificationCenter];
    [notCenter addObserver:self
                  selector:@selector(loggingOut)
                      name:NSWorkspaceWillPowerOffNotification object:nil];
[[NSRunLoop currentRunLoop] run];
}

This observer traps the Restart, logout and shutdown, and calls function loggingOut
Then create a function 'loggingOut' and log the NSUsername to logout again with the IP.

Hi,
thanks for you answer.

I worded on the script yesterday morning and I have that :

#!/bin/bash
# logout script
username=${1}
date=`date "+%m-%d-%Y"`
time=`date "+%H:%M:%S"`
computer=`hostname`
ip=$(ip addr show en0 | awk '/inet / {print $2}' | cut -d/ -f 1)
mac=$(ip link show en0 | awk '/ether/ {print $2}')
logfile="/var/log/usertracking.log"
echo $date" "$time," "$username," "$computer," "$ip," "$mac," logout" >> "$logfile"

But ..... in the log there is no IP and no MAC address ... I don't know why :

10-06-2016 11:29:46, *****, ****55.local, , , logout
10-06-2016 11:30:59, *****, ****55.local, , , login

That the first thing.

After I will have to export that file to a Sharepoint

On the mac you don't have a command ip addr

Try the following:

....
ip=$(ifconfig en0 | awk '/inet /{split($2,a," "); print a[1]}')
mac=$(ifconfig en0 | awk '/ether/{split($2,a," "); print a[1]}')
....

Please note the interface, en0 is the interface of my WiFi.
This might be eth0 ?
