> **Note:**
> The ***telnetd*** is NOT installed, because the file is missing in the (read only) directory /usr/bin.
Just append the code below at the end of that file. On the device where the script was not present, I've just created it.
Create a file in ***/vendor/user*** with the name ***usermod.sh*** and the following content. It has been tested with devices connected via ethernet and wireless. Please adjust the IP address for the web server (in my case 10.1.1.22).
```
sleep 5
cd /vendor/user
cat <<\EOF >> /vendor/user/usermod.sh
#!/bin/sh
# user modification to allow telnet to the device and shut down WiFi after 5 minutes if device is connected by ethernet.
sleep 10
# get telnetd from full version of busybox and start in background
mkdir /tmp/bin

Add a link to the new script in the existing ***user.sh*** script. Here's the content:
```
echo '' >> user.sh
echo '/vendor/user/usermod.sh &' >> user.sh
echo '' >> user.sh
```
The shutdown of the 'apcli0' WiFi interface does not work within the script when called in the first place, however it works a bit later if executed manually. So I added the 300 seconds (5 minutes) sleep and executed the command twice. Now it looks that it works as expected. I also added some code, so that the WiFi interface is NOT shut down if the Ethernet / LAN interface (eth2) does not get an IP address.
Compared to the the section [Enable telnetd](/TELNETD.md), the code above has a little enhancement included, because the downloaded version of busybox is used as the shell ***/tmp/bin/ash*** instead of "build-in" version. You can see the difference, because the shell prompt message is ***BusyBox v1.23.2 (2016-09-27 07:54:34 CEST) built-in shell (ash)*** instead of ***BusyBox v1.12.1 () built-in shell (ash)***.
