Quest 1 (5p)
Loo skript, mis paigaldab ntp teenuse ja seab serveriks ntp.eenet.ee
#!/bin/bash
#installeerin ntp teenuse, vastated promptides yes
#Lisan "server ntp.eenet.ee" ntp confi faili lõppu
#teeb teenusele restardi
export LC=ALL_C
sudo apt-get -y install ntp
echo "server ntp.eenet.ee" >> /etc/ntp.conf
service ntp restart
Quest 4
Teha skript, mis saab käsurea parameetrina ühe stringidest MD5, Blowfish, SHA256, SHA512 ja leiab üles kõik kasutajad, kellede parooliräsi on antud algoritmiga räsitud.
