Linux Administration Cookbook

Getting ready

For this section, we can use the Vagrantfile from the first section.

We will be using centos1 and centos2 for the first part, and then debian1 and debian2 for the second part, sending logs from one box to the other.

Open two Terminals and connect to both centos1 and centos2; install tcpdump on both boxes:

$ vagrant ssh centos1$ sudo yum install tcpdump -y$ vagrant ssh centos2$ sudo yum install tcpdump -y

For part two (journald), connect to both debian1 and debian2, and install tcpdump and systemd-journal-remote on both boxes:

$ vagrant ssh debian1$ sudo apt install tcpdump systemd-journal-remote -y$ vagrant ssh debian2$ sudo apt install tcpdump systemd-journal-remote -y
