Man vs Cisco :)

Thursday, November 29th, 2007

Ok friday is going to be hopefully my last day studying for BCMSN since saturday morning I am gonna take the exam.

Feeling good but not great, wireless is perhaps my weak point but I know a good deal.

Well we shall see saturday :)

Edit: Passed the exam 923/1000, it was not all that hard. I was pretty scared from the BSCI since I barely scraped through that one. Weakest part of the exam for me was Voice and than Wireless. No contacts with wireless equipment at all and next to none with voice so it was expected. People say BSCI and BCMSN are quite harder than the rest of the CCNP curriculum and I certinaly hope so. Anyway 2 down 2 to go. Hoping to shoot down these by the end of May since I will be also trying to pass my MCSA upgrade to 2008 until end of January (while the second shot is active).

Thanks to everybodies support and see you next time :)

CCIE4U 3 sessions free! One per person please :)

Thursday, November 15th, 2007

Well as I said I still got three sessions free and want to give them away.

If you want them please leave a comment here and soon as the sessions are.

16.November.2007 04:00 -08:00

18.November.2007 00:15 -04:00

19.November.2007 00:15 -04:00

I will send you the user and password for logging in and you can hopefully use it better than I can. If there are more than 3 people that call in I will decide on your willingness to put it to good use, so please write something in that comment and not just “Gimme the session!”

CCIE4U……CCIE4who?

Thursday, November 15th, 2007

Well I said once how I was switching my rack rental providers. Big mistake, not saying it but doing it. My attempt to get a nice rack session has gone totally berserk. Not that they didn’t try! When I first contacted them they were nice enough to open up a Moneybookers account and accept that as payment since I don’t have PayPal. But the here is what was missing.

  • Booked the sessions  - Went well
  • Waited for the instructions - never got them
  • After my first session started, mailed them for instructions and got them… later in the day (ok perhaps slightly my bad I could have asked for them somewhat sooner)
  • Second session, login is not working! OK they give me a freebie but that is what is expected.
  • Third session I start working and after about an hour screen freezes up and I have to disconnect. After 20ish minutes or so (went to get something to eat) I log back in just to find the complete rack turned off. So I am in no mood to start all over again.

I still got 3 sessions left and I am giving them away! Check out the next article for more. :)

Stress-o-meter

Wednesday, November 14th, 2007

Don’t know how about you but I work a lot, and mostly people in IT do. Mostly when I combine learning (for the job) and working I am on a 60-70 hour weeks non stop. Some days I work more and some days less, when I compensate with learning more. Saturdays are pretty much the same, Sundays I usually take a day off, well perhaps just a couple of hours of testing in the morning.

If it is luck or not, I am not sure, but now and than I get a twitch in my left eye. That is the moment I realize my body is saying “take it slow”. Stress, caffeine and overworking is just a routine nowadays so can you spot when you are overstressed? What is your stress-o-meter?

P.S. Decided to get off Coke (not the drug :) ) and get back to coffee as at least it has less calories.

P.S.S. Don’t give up!

S.O.S. give yourself a day off :)

Server Core Domain Controller

Tuesday, November 13th, 2007

So what is it, why do we need it and how do we best use it? These are all personal views from documentation and some fiddling around in virtual machines as its still in RC0 :)

Server core has lower requirements than a full server as it is really bare bones. You need only 1GB of HDD space to install it.

As it has limited capabilities it also proves to be a smaller target for malicious attackers (is there any other kind? :) ). Server core supports DHCP, DNS, File Server and Domain cotroller of the infrastructure roles. It can’t run server applications and you sure as can’t develop any. There are standard features that are support of course IPSec, WS-Management, WMI, HTTP, event logging…
Remote management is pretty much the same if you are using one of the Server Core supported communication protocols.

And for last, management is done by using a command prompt since there is no GUI, if you know you stuff will be easy since there is not like a million services to update and take care of.

So there you go just a small look at one of the topics :)

Whats new in Windows Server 2008 Active Directory

Sunday, November 11th, 2007

For starters there is a bunch of abbreviations.

AD FS - Active directory federation service - as we come closer to everything on the web situations ADFS gives us a SSO (single sign-on) situation where we can log on by browser to all applications through active directory.

AD CS - Active directory certification services - allows to give out certificates to users/computers/organizations as a part of our PKI (public key infrastructure)

AD DS - Active directory domain services -    there is a new wizard to help with all the installations, some of the improvements are in the advanced mode which I still have to check out

RODC - read-only domain controller -  somebody has been thinking and here is a role specially tailored for low physical security locations, RODC has a read-only replica of AD. More RODC goodness means no two way updating, its just download there, local server admin can hack away at it as much as he want but no poisoning the AD possible.

AD RMS - Active directory rights management  services -can you say access control? :)

AD LDS - Lightweight directory services - built on ADDS but has the advantage of not needing domains or domain controllers and you can install several instances on one machine.

AD DSA - Domain services auditing - logs changed in AD DS

Second of all its got some great features like:

  • Background zone loading
  •  Support for IPv6 addresses
  • Global names zone (helps with getting rid of WINS addresses)

Thats to get you started :)

Well…

I am lagging on my BCMSN almost a month now and will surely be another month before I get out and try to pass it. On top of that at work it was the short stick for me, so being the chosen one to pass the upgrade from MCSA 2003 to 2008 will interfere with my Cisco plans. Not to let all that drag me down I scheduled 5 session in the coming 8 days (Sunday to Sunday) so should have something new to write about by the time I finish. And off course I will have what to say from in the Microsoft arena and the new Server  2008 RC0.

Thats all folks :)

Using both internet and a Terminal Server in dynamips

Wednesday, November 7th, 2007

Well I have spent surely 15ish hours trying to get this one going.

Even with another network card took me some time to figure out. I use ADSL for internet access and everything was going down that pipe as it was the default gateway. So here is the list of commands I used to get everything working.

#Start your lab

brctl addbr br0
brctl addif br0 tap0
brctl addif br0 eth2 #my non connected card used purely for this
ifconfig tap0 up
ifconfig eth2 up
ifconfig br0 169.254.0.1 netmask 255.255.0.0

route add 169.254.0.2 gw 169.254.0.2

It seems really stupid I tell my computer to use 169.254.0.2 as a gateway to the host 169.254.0.2. But without that it just doesn’t want to work. Now that I am totally connected I can finally get on with some practice. :)

A bit of links…

Keep at it guys you make my days easier :)

Rack rental thingies…

Saturday, November 3rd, 2007

Well that was an unpleasant surprise! I just logged on to CCOnlineLabs and saw a price increase from $15 to $20. Not that I wanted to buy since I still have like 5-6 sessions available but although they were great (hats off to Tony Shaffran) my money is gonna go elsewhere. CCIE4U already got some of my mine as they were nice enough to accept moneybookers after talking to them :) And they got shorter 4 hour sessions which work great for me. Anyways thinking of getting some real switches and going commando on them :)

Ah thats it for now gotta get to work even on Saturdays. Take care people!

Edit 11/15/2007:  After some bad experiences I guess its back to CCOnlineLabs and Tonny.
