Fail2Ban is an intrusion prevention framework written in the Python. It ban IP’s that makes too many failed attempts or performs any other unwanted action within a time frame defined, using iptables, thus helping the system admin to prevent attacks.

Though its very helpful, in an office network that has only one public IP and multiple users accessing the same server, there are chances that IP’s gets blocked more frequently. For Eg, let the setting be like 3 failed attempts on ssh port in 60 mins will block the IP for 2 hours. If 5 systems in a network access the server and any 3 of them makes one failed attempt, the IP gets blocked.

Atlast, today I got the opertunity to deliver my seminar, which was part of 7th semester B-Tech syllabus. I was among the last few who couldn’t present on the sheduled time. My proposed date was Dec 2, 2010; the day of MESTECH ’10.

Unlike most of my classmates, I love to deliver talks or seminars, in front of audience, even if less in number. But this time only 2 lecturers were present and that too just to evaluate 🙁

The seminar was on Python is Scientific Computing, based on a paper by Travis E Oliphant.

Here goes the slide and its tex source. The presentation uses progressbar beamer theme by Sylvain Bouveret modified by my friend Jishnu.
