3.1 Fifteen minute ruleIndex

Your time as a student is valuable. See the Week 03 Notes HTML.

3.2 CommandsIndex

Keep a notebook with a List of Commands in it. - You need to write down yourself what each command does. - I will check for this list in your lab periods. - Check the updated list of commands each week.

3.3 Locked outIndex

The CLS will lock out your IP address if you can’t type your own userid correctly.

If this happens, you have to follow the posted directions to have me unlock your IP address. You can change to another IP address. You can always come to school where no IP addresses are locked out.

3.4 Attacks on the Course Linux ServerIndex

• Count the attacks: fgrep -c "refused connect" /var/log/auth.log
• Another way to count the attack lines (slightly less efficient): fgrep "refused connect" /var/log/auth.log | wc
• See the current list of evil host IPs: less /etc/hosts.evil
