Our tutors finished grading of the exam today and the results are visible now. 

The exam inspection will be this Friday, 9-11. Please let Marius Steffens know if you want to attend the inspection and when you approximately plan to come, so we can determine what size we might need. 

Finally, on a less formal note, I want to take the opportunity and thank everyone for their positive feedback on the lecture. I am honored to have received the Busy Beaver teaching award for the course as an outstanding basic lecture. I am aware of numerous "rough edges" in the lecture, but still very much welcome additional feedback you might have. I also want to thank again the TAs and tutors for their support in making this a (hopefully) nice lecture.

Registration backup exam

Written on 01.04.19 by Ben Stock

All students who are not able to register through LSF, please send an email by at latest Wednesday to marius.steffens@cispa.saarland to register for the exam. Any later registrations cannot be taken into account as we need to print the exams.

Exam registration

Written on 07.02.19 by Ben Stock

I have just imported all students from LSF again. Please check in your student overview if we have marked you down as registered for the exam. We will be printing the exams tomorrow, so please check right away.

Exam tutorial tomorrow

Written on 04.02.19 by Ben Stock

The exam tutorial tomorrow will be held in CISPA's lecture hall (turn left when you enter the building). We have an important visitor until around 11:30, so please refrain from arriving before 11:30.

Lecture slides and evaluation results online

I have uploaded the slides for today's lecture as well as the overview of the evaluation.

Regarding exercise sheet 10

Written on 12.01.19 by Ben Stock

You must not take a shortcut with the domain name of a name server, e.g., you have to use 

dig @198.41.0.4 saarland NS

and not

dig @a.root-servers.net saarland NS

This will yield less points in the exercise. If you already have the NS, e.g., for a given TLD, you do not have to query… Read more

This will yield less points in the exercise. If you already have the NS, e.g., for a given TLD, you do not have to query the root name server again.

Experiment: Lecture slides online

Written on 11.01.19 by Ben Stock

As an experiment, I have uploaded today's lecture slides as a PDF already and have decided to skip any quizzes for today.

I am looking forward to your feedback on this after the lecture.

Plagiarism

Written on 04.01.19 by Ben Stock

There seems to be some misunderstanding regarding plagiarism. In particular, whenever you use an online resource which you just copy, that is considered plagiarism (regardless of whether you provide the URL). All answers are supposed to be in your own words.

There seems to be some misunderstanding regarding plagiarism. In particular, whenever you use an online resource which you just copy, that is considered plagiarism (regardless of whether you provide the URL). All answers are supposed to be in your own words.

Moreover, if you have the same solution as someone other than your submission partner, this is also plagiarism. We have seen cases where two students had the same solution but different tutorials. It is not entirely hard for us to find such cases.

In particular, to be very clear: the first attempt at plagiarism gets you 0 points for that sheet, the second time we forward your information to the Prüfungsamt and you lose the right to take the exam.

Feedback and photos

I want to take the chance to thank you all for the feedback so far. Since I cannot respond to the anonymous feedback in the CMS, let me summarize and say that I take this seriously (regarding improvable phrasing of the exercises, slide and solution upload).

  • We will make all solutions available in the week of January 7th. As for the tutorial sheets, this might take a bit longer.
  • The slides are not available before the lecture on purpose. I will consider uploading them, but at the very least without the quizzes). 
  • As far as unclarity on the sheets go: if you feel this way, let us know early on. If possible, we can then change them accordingly.

 

Apart from that, I hope you have enjoyed the lectures thus far. If you have taken any reasonable quality pictures in today's lecture, I appreciate if you can share them with me via email.

Merry Christmas!

Christmas lecture

Written on 18.12.18 by Ben Stock

Since we have our final lecture of the year this Friday, very close to Christmas, I am prepared to spread some holiday spirit. In particular, I have a red and white Christmas hat that I can wear. If someone is able to provide additional "outerwear", I am also willing to wear that ;-)

Bug in slides

Written on 07.12.18 by Ben Stock

There was a bug in the slides of this week. The IP header checksum is calculated on the entire remaining header of the IP packet (except for the checksum itself, naturally). The slides have already been fixed and I left a note in there. 

Lecture recordings

The lecture recordings up until Lecture 05 have been made available now. Seemingly through our setup, though, there is a bit of audio loss (mostly in the last 10 minutes of each lecture).

The lecture recordings up until Lecture 05 have been made available now. Seemingly through our setup, though, there is a bit of audio loss (mostly in the last 10 minutes of each lecture). We are still working with the university to move from a hacky solution with an extra laptop capturing the audio via an antenna to something more usable...

Padding Oracles out of scope for exam

Written on 02.11.18 by Ben Stock

Due to my misjudgement of the timing of today's lecture, I was much too hasty through the padding and padding oracle parts and lost my cool there. Please accept my apology for that. These topics will therefore not be part of the exercises or exams.

Due to my misjudgement of the timing of today's lecture, I was much too hasty through the padding and padding oracle parts and lost my cool there. Please accept my apology for that. These topics will therefore not be part of the exercises or exams.

To avoid that you forget about this until the end of the semester, I have removed the slides from the PDF version of today's lecture.

Office Hour room change

Written on 29.10.18 by Ben Stock

The office hours will be held in CISPA this week (room 0.06).

Exercise Sheet 1 online

Written on 26.10.18 by Marius Steffens

You can now find the first exercise sheet in the Materials section. Read the submission instructions carefully and do not forget to include your name and matriculation number in the final submission.

Tutorials

Written on 23.10.18 by Ben Stock

We have opened the sign up process for tutorials. It would greatly help us if you can exclude certain tutorials so that if a single date does not work for anyone, we can still adjust the slots.

First lecture

I have heard that a number of students showed up last Friday for the lecture. While my group's web site clearly said that the lecture only starts this week, this was not made clear in the CMS and all information pages linked here.

I apologize for this mishap: but on the positive side, this is the only time the lecture will not take place :-)
