OK, question

[RevAlSharpton]

I have an old laptop, 400Mhz Compaq Armada, that I bought for $50. I've been playing with the Cisco IOS simulator and having fun. Then I stumbled upon this.

Does anyone have any experience with this? It's a Linux based router program called Zebra.

haven't heard of it before.

I did stumble across this a few days ago.

Thanx for the links. I've been playing with Ubuntu for a while now, and I did some more research. I found that all Ubuntu flavors come with a router program called webmin.

I also found an interesting firewall program that most people are recommending called Firestarter.

The Cisco IOS simulator is from Boson, called NetSim. The damn school sold us v5.00 which Boson no longer supports (I had some Vista install issues). Boson sells v7.00. I'm gonna check out the link you sent me.

Oh, also I have 2 questions. I'm having major problems with this professor trying to ruin my 4.0 GPA. He made me miss one question on my 5th week exam and another one on my midterm. Here's the questions with my answers:

9. Question: What configuration register setting will boot the router from ROM?

Your Answer: 0 in the boot field value INCORRECT (A correct answer: 2101)


9. Question: All of the following are major elements of a typical router configuration EXCEPT:

Your Answer:
Passwords
Interfaces
Routing Protocols
DNS INCORRECT
Flash Memory CORRECT ANSWER


Okay, I'm not understanding this one. There are several configs for different models, and configs like 0x2122 and 0x2124 also boot to ROM.

And doesn't Cisco boot the IOS and configs from Flash unless you have to pull from TFTP or go to ROMMON? DNS is Domain Name Server, correct? I'm debating contesting, but I want another opinion.

Thanx in advance for listening to my rant and any advise and/or reasoning is appreciated.

in response to the conf reg question, confreg of 0 won't work. setting which conf reg the router uses is like setting a jumper.

2101/2102 are default for normal use.
2142 is used alot of times for password recovery as it allows you to get into the router without loading the config.
That chart in the link is very helpful for deciphering out the different settings.



as far as the dns question. A router can not act as a dns server and in the actual config, there is nothing to support a dns server. yes it can use a dns server to lookup stuff, but it itself does not do anything relating to a dns server.

Your Answer: (stuff found in a router config)
Passwords - login / enable
Interfaces - eth/gig
Routing Protocols rip/eigrp/ospf
DNS INCORRECT - nothing for setting dns
Flash Memory CORRECT ANSWER - when you do a show run, it will actually show you some info about the flash. kind of a stretch, but more router related then dns.

lol i took a cisco networking class 2 years ago... i recognize most of the terms you speak of, but forgot the importance of them >.<

/off topic: i should probably get some certificates, any fairly easy ones to get? i hear A+ isnt the hardest one out there.

Thanx. I thought the conf reg differed for different models. So, 2101/2102 is an IOS default. Got it.

A+ is the easiest (hardware, os's)
net+ is easiest networking
ccna is a tough test (but still entry level in the whole scheme of things)
ccxp is even tougher (you start getting respect at this level)
ccxe is ludicrous (do a google search for people that have passed their ccie, and show off their "at home" practice labs....)

how are the MS certs? (MCSE/MCSA)

[YO_MA_MA]

how are the MS certs? (MCSE/MCSA)

good question, one of my friends was talking about the application/os one (whichever that is) for MS. wonder if hes taken it yet and how it was. anyone know?
