+# Instalar OpenSSH (sshd)
+apt install openssh-server
+# Comprobar funcionamiento de sshd
+systemctl status sshd
+

+# decir que sí a reconocer el host y entrar con la contraseña
+ssh examen@172.16.40.26
+
+# usar `su -` para entrar como root
+[servidor:root] (via ssh para el resto del examen)
+# instalar apache2
+apt update
+apt install apache2
+# comprobar funcionamiento de apache2
+apt install curl
+curl localhost
+# configurar dominio examen.es
+echo "127.0.0.1     examen.es" >> /etc/hosts

+cp 000-default.conf examen.es.conf
+# editar el archivo para que salga como aparece en el `cat`
