Hello Mux,
I haven't done OSCP myself yet, but from what I have heard and read about it and considering your experience, I would say you have everything needed to get a lot out of it. This means if you are already interested in OSCP by yourself and want to get into it, I see no reason why you would not be eligible for it.

Andrew has done the course, I am sure he will be along latter, and can provide some on hand experiance as it were.

Mux,

I'd agree with Dark_knight and Awesec, sounds like you should have enough of a background to handle the material. With the server experience that you have the networking prerequisites shouldn't be a problem for you.

However as Dark_Knight mentions there is some programing involved, which if it's not something your've done before may take some additional time to learn the basics. Again though the programming requirements are quite basic, and explained well in the course material (imo), but I had some programming skills before taking OSCP so your mileage may vary.

It is a great course, if you're up for the challange and are willing to put in the required workload you'll do well. If all else fails you can always 'try harder' Good luck
