Linux VM: Show IP on Boot

If you want to show the IP of your linux VM after boot (for use with local KVM, …), you have two options:

The easy way

echo My Ip address: \4{eth0}"" >>/etc/issue

Where you need to replace „eth0” with the name of your network interface (might be „enp0s3” or whatever).

The cumbersome systemd way

First, create a „/usr/bin/show-ip-on-boot.sh” script:

#!/bin/sh
ip a | grep "inet" | grep "eno" | awk -F/ '{print $1}' | awk '{print $2}'

and then create a systemd service for it, where you redirect the output to the console.

[Service]
Type=oneshot
ExecStart=/usr/bin/show-ip-on-boot.sh
StandardOutput=journal+console

I know, what solution I prefer … ;)
