From the Classroom Whiteboard/ChalkboardIndex
- Take notes in class! Your in-class notes would go here.
Microsoft supports Linux command-line programs on Windows 10
Finding world-writable files in your accountIndex
Don’t create files or directories that anyone (“other”) can write, except the required ones in the Assignment #08 HTML head directory!
- To learn how to
find these world-writable files in your account, look for the text world-writable in all the course notes.
- To search the course notes, re-read Items 7 and 8 in section 4.4 of Assignment #05 HTML. See also the examples in the web notes on finding files in the Week 03 Notes HTML.
- You will be able to identify which course notes web page you should read to find out how to find world-writable files.
The test integer compare is not the same a string compareIndex
The test helper command uses a different infix operator to compare integers and strings. See Shell Script Problems.
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.
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.
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
