by Vasil KolevWhy when I always remember to blog, it has to be for more than one thing? Can’t I be somewhat more organized, to make categories, and to write everything in the right one, etc?
(looks like – no)
Yesterday was the second Network Security test, which according to me was easier, according to the students – no… The results are pretty bad, we swore a lot while grading them. Looks like the same with some of the course papers (Pentchev looked at one and asked me “How many points should I write for something that’s a translation/copy of the marketing data of 4 products?”).
Looking at the result I’m thinking that part of this is the students’ fault, but a part of this is our fault… I’m thinking not to give any more lectures the next semester and to concentrate on something more useful (about it – some other time).
Something more interesting – I started working on the problem “What if we have 5 separate remote points, and we want to have one multi-point VPN, which they can use for communication?”. One solution (that we utilize right now) is to have a point-to-point tunnel between every two that need to communicate, which is extremely ugly to support. Another one is to chose one for a hub, which we can’t do because 1) it becomes SPOF, and 2) we don’t have a place with that much bandwidth.
In the end it turned out that there’s a normal solution – WanDaemon, or to be more specific – Etud, ethernet over UDP daemon, which is exactly what’s needed. Turned out that it even compiles and works under FreeBSD, what’s left is to write some scripts for pushing configurations (addressing, routing, etc.) on the machines (I’m not going to run dynamic routing, Voland promised to shoot me if I try :) ).
Also it should be noted that the behaviour of the country around Bush’s visit is like the one from 50-60 years ago towards the Soviet Union…
