and someone wasn't paying attention AT ALL during the semester.

Wow, it sure sucks to be you right now.

by evilhomergd

So I'll only give you two that are easy... You're on your own for the rest of your homework...

7. What does ?/? signify with IP addressing
A: It is used to signify the number of bits used for an IP Subnet. 192.168.0.0/24 refers to a class C subnet with a subnet mask of 255.255.255.0. You can check out this article for some good insight into subnetting: http://articles.techrepublic.com.com/5100-1035-6089187.html

8. How many available hosts are there in a full class C address? What?s the subnet mask for a full class C?
A: In a class-full subnet, there are 254 hosts available for a class C subnet. Example: 192.168.0.0/24 - 192.168.0.1 would be your first available host and 192.168.0.254 is the last host with 192.168.0.0 representing the network address and 192.168.0.255 being the broadcast IP address.

by nyruh1

coincidently, have most of the answers, so forgive my boldnes. This is one of the three that escaped me for the moment. Thank you again.

by dumphrey

use ip subnet zero enabled on a cisco router, you can actually use the .0 address and a host address as well as the network address. But there is no point to that really.

by jdclyde

when I went through the academy. They were used to being able to just show up to classes and squeaking by. Networking is NOT one of those classes.

The thing that saved my ass was I was working in the field already, so I had a working understanding of the networks, just didn't know all the names and WHY things were done like they were done. It was filling in the blanks for me, but the people that are new to it, are so screwed.

Not to mention, if you just get the CCNA, it only qualifies you to be level 1 help desk. :D

by kjell_andorsen

Look kid,

Looking at this, it's pretty obvious that you're in school. Chances are this school costs either you, or your parents alot of money. You may think that all that matters is getting the degree, and that a pass is a pass, but if you're going to school to learn techie stuff like networking you have to actually LEARN all this. If we just give you the answers you won't learn the material and you'll make a crappy networking engineer.

So, do your research and learn your stuff. Most of this is pretty simple and shouldn't require too much effort to learn and understand.

by jdclyde

is people that DON'T learn these basics finish up their degree and make the rest of us look bad.

If he can't understand these basic concepts, NOW is the time for a change in curriculum.

I blame the councilors for people like him. They say "you can make a lot of money in xyz" field, so the dumb kids go into it for the money even though they don't have the technical skills to LEARN the field. Of course, the money is no where as good as they promised either.

I went through the Cisco Academy. It started out with four classes of 24 students. It ended up with 8 people finishing and passing the final class. Half drop after the first or second class.

by nyruh1

Dude, hold up. I understand what ur saying. If its $$$ that thats the moto, there are better thing to do and be a lot more productive and fun. I love tech as well as other things and it is a way of life. Don't lump me with those who stick their heads in the kitchen to see if its too hot. I'm sorry for those that dropped out, but guess what congrats on you passing. How about trying to encourage and enlighten those who want and try/are trying too, instead of lumping and leaving. Not all of us are "giving up"

by nyruh1

Terminology is whats throwing me off. I've worked in different sectors of IT/Telecom both civ & military. Having to "unlearn" and relearn and "unlearn" just to relearn, that is what happening and I am not mad. By the time most of these posts were made, I had realized that I knew 65-80% of it already. This is not a game to me, and I am paying for it myself...NO HELP. I just wanted to make sure I am on the right track. I am grateful for you guys saying "do it ur self", in the end it means more and point...I WILL HAVE TO DO IT ALONE!!!

by kjell_andorsen

Well, I will admit I made some assumptions that seem to have been invalid when I read your first post.

Kudos on remaining mature and not letting our initial negative responses get to you. The attitude you're displaying here will serve you well :)

by jmgarvin

Crack a book, go to google, find the information, it's everywhere. As a matter of fact, many of these questions are already answered on TR, you just need to do a quick search.

Look, it you are in IT for the money, you're in the wrong field...get out now.

by jdclyde

run.

Also if you do not enjoy learning new things, IT is again the wrong field for you.

As fast as technology changes, all skill sets have about a 5 year shelf life.

by sleepin'dawg

I'd say it's more like three years if you want to stay bleeding edge not just cutting edge. Stuff in the pipelines right now is going to shorten that even further. Think AI; Neural Nets; fibre optics and Optical processors. Scary stuff, which I used to think I wouldn't see in my lifetime or live long enough to see, may well be coming to market within the next 18 months, if not sooner.

by nyruh1

RE:Your beliefs are in question here ...

OK man. If that is how you do. Sorry you feel that way. I respect your opinion and you for making it. Good looking out on the ref material. I don't spend a lot of time asking question on the net, so pardon my novice expertise on the matter. I'm usually face to face. BUT HEY, today was a learning experience. I am grateful.

by tony hopkinson

The answer is yes.

You do need some questions answered!

I suggest a career change perhaps you could come to the UK and get an A level in Macdonalds...

by shellbot

Since that post was edited by Beth..I had to make up my own words to it..

Geez...it was kinda harsh..what language..

]:)

by tony hopkinson

ego too large for me to be damaged by someone who can't even use google.

You have to respect someone before their opinion matters.

by tony hopkinson

here in my time, some even said thanks.
I don't help people who give every indication that they want to sit on their arse and have me do the work though.
You want me to do that get your wallet out, or become my manager. Note that won't spare you abuse mind, I am that sort of c**t.

Type those questions one by one into google, just try ffs!

You think any us got into a position where we could at least point you in the right direction, or at least help you avoid the wrong ones by just by posting to forums?

Do yourself a favour stop looking for the easy way out, that's always obvious, it's door marked Exit.

Motivation 101

by nyruh1

That is what I am saying. Instead of dwelling on the 222+ that failed or dropped out, why not praised those who stuck with it.

by nyruh1

That is the reward for you. As long as you feel good, and a lot of times at can help other....like me, just being able to hear it, or read about it.

by nyruh1

nor did I state he was. I am doing my research as well, just wanted to get some outside help. Kudos to u, for making that statement. You have put me in my place.

by nyruh1

i was unintentionally brash. I should have said PLEASE. Iwas wrong for that. No I don't. I take whatever info and like everything else, research it. But thank again for showing me a different angle/side.

by nyruh1

it has probably been reveiwed by now. So I shot back at a wuss, sorry "person" that come at me wrong. I have a right to defend my pride and dignity as much as the next man. I understand I could have use a different tone than before.

by kjell_andorsen

I didn't get a chance to read that one. Sounds like it was pretty "spicy".

Ah well. I'm just gonna go sit quietly in the corner now ;)

by nyruh1

We're making more out of it than what it was. Maybe I should just sit in a corner too...he he

by jdclyde

when you get in the meat word, the "cisco cookbook" and "hardening cisco routers", both by o'rielly are never far away.

For the purpose of your class, the book that you got in the class is going to be your best bet. They don't teach over everything, so you would/could spend time on topics not relevant or not dealing with the correct version of IOS.

by nyruh1

I also fail to mention that I am not in any class, yet. Not until spring. This is all my own prepare work. So thank for EVERYONE input. I am learning what to and not to say on the forum, just so it go a lot better.

****SORRY BETH****

by dumphrey

from cisco Press to be top notch. I used it during ccna 4 a lot to be honest. All the main commands and syntax examples right at your fingertips with a handy glossary.

by kjell_andorsen

PRetty much all the questions you asked can be answered by learning the material in Wendell Odom's "Official CCNA Exam Certification Library" from Cisco Press. This is the material I'm using to prepare for my CCNA, I've been very impressed by them so far.

by nyruh1

Bad choice of adjectives. I try to treat people like I would want to be treated but you get those few that just......WHOOOO!!!! Bad thing is, I have been around the world twice, and never reacted to anyone like that.

by dumphrey

but any abuse you have received here is to be expected based on the nature of your questions. 1) Its obvious you are in Cisco 1 or 2. If you are in 3 and need to know about subnets, its to late for you. 2) Many of those questions can be easily and fully answered with some simple google application. 3) Most of the members here are working professionals (I know I know a very sweeping statement) and as such do not have time to answer so many large question. If you had asked for advice or variable length subnetting for example, or logical and'ing, you would have received several good answers. It kinda like the old RTFM, make some effort, ask specific questions. The cisco on-line ciriculum has all the info in the text chapters and in chapter reviews. If this is part of your study routine, may as well add re-reading each chapter summry and taking notes.

by nyruh1

Thanks.YES, I am just starting out. NO, It is not too late you me. No, I don't believe I have been abused. YES, I too am learning so that I can become a BETTER professional. YES, I should have asked MORE SPECIFIC questions. Please understand. You can't hurt my feeling by making whatever statements. Regardless what you think, It is helpfull

by sleepin'dawg

I can almost guarantee your TR lifespan to be a very short one indeed, especially if you manage to piss Beth off after such a short time here. I suggest you grow up, mind your manners and next time try hard not to trip over your own dick.

You've been around the world twice??? I wouldn't credit you with having been around the block once especially if that's your manner of response. Now go home and cry to your mommy; this is a place for adult thinking only [i](with the exception of Friday Yuk)[/i]

[b]Dawg[/b] ]:)

by nyruh1

Good comeback. I wasn't trying to piss off anyone. Its good to know that you understand how far a block is. Mom's pasted away, so I've been a BIG BOY for a while. Oops...wipe your lip. I made my mistake and apologize. What don't you get. I didn't come here for that. All this meaningless comback is for not. I don't know Beth and wasn't attempting to stoke any fires. there is no need to raise any BP's. Its over with so lets move on. Respect to you.

by shellbot

Its obvious the b!tch fairy has visited a few of us this week..
everyone seems to be on the edge!

by jdclyde

we need a massive supply of chocolate to be sent out, along with some extra strength mydol......

:D

Then some flowers, bubble bath, and mommy parts! ]:)

by nyruh1

This is want I am talking about. Not giving answers, but piquing my interest in why and how. Thanks

by jdclyde

If you had been paying attention in class, you wouldn't be in here asking people to hand you the answers.

Go back to your book and the on-line study guides you got in your class, ALL of the answers are in there.

Your not giving up, but you are looking for the easy way out of having someone else do your work for you.

I "encourage" you to go back and do your homework and re-read the assignments.

It isn't about the friggen GRADE. Don't you get it? It is about learning and KNOWING this stuff. There isn't a GPA listed on your diploma.

I passed through cisco8 because I had a study group that would spend HOURS outside of class time working and studying.

Believe me, if THIS is hard, you are not going to make it. this is the EASY part.

by nyruh1

Who said that I was in a CLASS. I never said that. U assume too much. I am doing this on my own, to PREPARE for class. I DON'T assume that anything is easy. You had a class, I am going solo, at least to start. I believe that I will be part of a study group as well. Don't count it out. This is all me. $$$ and energy.--"It isn't about the friggen GRADE. Don't you get it? It is about learning and KNOWING this stuff. There isn't a GPA listed on your diploma"--I am glad YOU figured that out. I never said that either....again you assume too much.

by jdclyde

the list came from somewhere. You made a list of what you didn't know? I am sure you can see why I am not the only one to reach the same conclusion.

Fine, I don't know you, and I don't know your situation.

Good luck.

by jdclyde

when you think how long it was from the 286 to the first pentium, and look at it now.

Good to see you poke your head in now and then, dawg!

I don't personally worry about bleeding edge, but an content with staying relevant and keeping my head above water. The main thing is having to become more and more specialized.

by jellimonsta

I am looking at going the next step to Sr. Engineer some time within this year. However, I came from generalist, and I am now Network/ Voice/ Security Engineer.
I am having a hard time deciding whether I want to 'specialize' or not. Right now I do route/ switch, VoIP, WiFi, Security, LAN/WAN. I am mostly Cisco, but do work with the Cisco/Windows voice servers and Cisco/Linux appliances.
I know what you mean about specializing though. The more I learn, the more I see I have soooo much to learn.

by jdclyde

It teaches us how much there is to learn. I have that hanging in my office, and have found that the more I learn, the more I realize how little I know. :(

We are just looking to put in a Cisco VoIP solution, and have been an exclusively *nix shop (servers) except for one server to run the symantec corporate, and we are moving away from that even.

I have just bought myself several routers and switches to make my own cisco lab. need to do a lot of brushing up so I can write the CCNP certs.

by nyruh1

Right you don't. Forget list, but I manitain that you were right about asking SPECIFIC questions. That is not to be forgetten.

by jdclyde

because yes, you were being abused.

You came in here and were seen as kid in a class looking for answers for the entire semester.

That is a valid reason for lots of abuse and ridicule. Sorry, but that is just "how we roll".....

I strongly recommend you read ESR's posts on how to ask questions on the internet.
http://www.catb.org/~esr/faqs/smart-questions.html

[i]Before asking a technical question by e-mail, or in a newsgroup, or on a website chat board, do the following:

1. Try to find an answer by searching the archives of the forum you plan to post to.

2. Try to find an answer by searching the Web.

3. Try to find an answer by reading the manual.

4. Try to find an answer by reading a FAQ.

5. Try to find an answer by inspection or experimentation.

6. Try to find an answer by asking a skilled friend.

7. If you're a programmer, try to find an answer by reading the source code.

[b]When you ask your question, display the fact that you have done these things first; this will help establish that you're not being a [u]lazy sponge and wasting people's time[/u]. Better yet, display what you have learned from doing these things. We like answering questions for people who have demonstrated they can learn from the answers.

by jdclyde

if you know WHERE your going to take the classes, go talk to the instructor. he/she can tell you what the book is that will be used for the class.

The problem with just ANY book is the answers CHANGE depending on which version you are dealing with.

Oh yeah, here is a tip for class. They will ask for the "MOST correct" answer, not for A correct answer. Fail to pick the MOST correct means it is WRONG. They got me with that early on, but I learned my lesson.

by evilhomergd

but this is more of a special circumstance for communication between two routers if memory serves...

by dumphrey

connections using vlsm if I remember correctly. But it can be MADE to work as a host address on a network, its bad practice though.

by sleepin'dawg

questions and not in the discussion area. Also, aside from specifics, brevity would be greatly appreciated. My first take on this was to pass on it and say nothing but if you are truly serious be more concise and limit the questions to 1 or 2. You can always return to ask more, later on.

[b]Dawg[/b] ]:)

by beth blakely

That was your one "get out of jail free" card. You used it up awfully early!

Stick around and you'll learn a lot. Just watch your fingers, 'cause these Pros tend to bite.

by beth blakely

Recent events have led me to the conclusion that I'm waaaaay too lenient sometimes. I'm going to delete faster and ban quicker than you guys are used to from now on.

This stinks because I'm really a super nice, understanding person who likes to give everyone the benefit of the doubt. :-) (Believe it, or not. ;-))

Unfortunately, this new attitude has become a necessity due to the "seagull" posters, multiple identity trolls, and spammers. Remember, everything I do, I do for you.

Maybe you already know all this, and more, but these related themes have come up previously as connected, and I read this recently, so here you go. The next time "page views" come up as a reason to be lenient, maybe this will help:

This particular poster is TRYING to redeem himself after his initial mistake with his posts, and other than the post to Tony (that I missed :( ) he has really suffered our chastisements well. There MIGHT be hope for him after all?

by charliespencer

I'm using a phrase that rattles around the U.S. armed forces (and probably others). It may be a bastardization of something else, but that's standard practice in any military worth a d@mn.

by jaqui

it's just that the phrase is so old that the plural of GODS was used as that was the belief of the original speaker.. and since it's actually older than writing, there is no way to know who originated it.
as far as intentional or not, since there was no attribution, it was plagiarization. :p

its hard to beat about $400 at ciscokits.com. The Bosun simulator is popular, but I found it to be very flaky and poorly designed, bad investment for $130. The Bosun testSim question banks on the otherhand are well worth the money.

by spiny norman

nyruh1, I'm not sure why your question ruffled so many feathers. Perhaps some of the "old school" techies are threatened by newbies. One's ability to flame a noob is NO indication one one's technical prowess.

Interesting that many folks "advised" you to do your own research; seems to me that you were doing just that. Your "shopping list" is a bit unorthodox, but offensive? Hmmm.

Dude, for an amazing amount of good info on networking, just lookup some of the keywords in wikipedia and follow the "related" links. Also, Cisco's web site has some FREE on-line training material that isn't bad.

FWIW, I've been doing this stuff for much longer than most here, but that doesn't make me better or worse than them - just older.

by jdclyde

I am finding Shells route to mommy parts is a lot more costly and time consuming than my old method.

"Excuse me Ms, does this smell like ether?"

by jdclyde

just that from all indicators, it was someone that was trying to get their homework done for them, and lazy people are never looked upon favorably.

If someone has a problem with a specific problem, or don't understand a topic, asking someone else is acceptable. Asking for the easy way out to an entire semesters worth of work is not. Also, there is a big difference between looking something up and asking people to feed you the information.

Simple, really, and nothing wrong with pointing people in the right direction.

To learn the topics, but a little less dry reading, I have always liked http://www.routergod.com .
