Forum: Geek Forum Topic: DoS started by: Beldurin Posted by Beldurin on Apr. 28 2002,08:56
I think I may actually have a little free time this summer and access to a LOT of equipment, so I was thinking that I might try to set up and simulate a DoS attack in the labs. I have access to probably 30 or so PC's. It's not that I plan on doing anything illegal, I'm just the kind of person that wants to know how stuff works (am also learning about router ACL's that are supposed to help prevent that sort of thing and may take the next step to see how those apply as well).Anyway, does anyone either know how to do it or know of a tutorial or something on what I'd need to do to simulate this?

well it all depends on what scale and what kind of DoS attack you want. There are may ways of doing it and it can be done to many servers. For example, a guy on a 56k was able to hang my computer that i was running apache webserver on in about 15 seconds with one tiny program. There are very easy ways to hang DNS servers like that too.So depending and what type of DoS attack you are experimenting with, you might not even need many computers. here's a little read about different types of DoS attacks. hope it helps. < http://www.astanetworks.com/resources/types/ > Posted by CNCJake on May 06 2002,00:30
Also, a little about ACL's unless you know what computers are waging the DoS war, ACL's will not help you because the only protocol you could block that would take care of everything, is IP, and you might need that one.

Yeah, I'm doing the CCNA curriculum (just finished semster 3)...I'm ass-deep in ACL's. You can block particular layer 4 protocols/ports though, rather than the whole IP suite. Posted by redpanic on May 13 2002,04:57
You might find some interesting things at the link below.< DoS Information & Such > edit: are you only going to try a DoS on a webserver? might be a good place to start. Posted by Beldurin on May 13 2002,05:29
Well, "server" is kind of a generous term...was planning on setting up a junk PC (possibly one of my spare ones) and using that...we don't really have the power to drop one of the bigger ones that we have.Then I was going to see if Dr. K. would let me try to smoke one of his routers...perhaps one of the 2505s. |
