Hello ak_k80

No such luck I'm afraid. "irqbalance" is something to do with dual core (or more) processors and doesn't get used - hence fails - on single core machines.

As to not seeing Wireless Networks when booted from the live cd I really can't offer any more help other than ask once more, is your router set up to not broadcast ssid's? If it is then networkmanager won't work.

hey bbfuller,

I have security enabled on my wireless network. Yes I understand the security risks. But the above commands worked just fine for me. Earlier I was getting the 8B06 error too. Did some playing around with Network Manager too, checked it to load on start-up but it still somehow doesn't show up.

And spiderweed I am on a VAIO too and got my wireless working. Did take a bit of work but when it starts working, its just cool and allows me to use Fedora everywhere.

Hello infinity99

There are at least three forms of security you can use on your wireless connections.

The first is the one most people are familiar with. WEP/WPA. That involves having some sort of encryption code in your wireless access point and entering the same information in the machine with the wireless network card(s) in.

Secondly, you can determine the unique MAC address of your wireless card(s), enter those in your wireless access point and tell it only to accept connections from cards with those identities.

The third concerns the name you give the access point to broadcast so that you can pick it from a list on your machine, either in NetworkManager or its equivalent on Linux or the Windows ZeroConf Service Discovery in Windows - or the Network Card manufacturers utility. That broadcast identity is called the SSID. It can be seen as a security weakness broadcasting that name as it easily alerts any hacker as to the existence of your network.

Most access points give you the ability to not broadcast that identity, in which case, supposedly, you need to know the wireless network is there and its name from some other source before you can type the name into a configuration utility on your machine and connect.

Problem is that on Fedora if you do that with NetworkManager (not broadcast the ssid) then at least the early versions of NM won't ever connect.

The jury appears to be out on the later versions.

Given a determined hacker I understand none of those prevent your network being hacked in 10 minustes. Not by me I hasten to add, that's just something a couple of people claim on forums I have read.

That said, it's a bit like putting locks on your doors isn't it. Unless you've got something someone really wants then they are going to go find some easier target.

It's the third of those options that I was concerned to ensure ak_k80 wasn't using in his access point. Otherwise it's very peculiar that no available networks show up in networkmanager.

Hello ak_k80

Can't tell you about the irq balance any more than that I'm afraid.

As to books, I particularly like "Linux in a Nutshell" from O'Reilly Press, but that is like a dictionary of Linux commands. The problem with that approach is that you wouldn't try to learn a language from a dictionary if you follow the analogy.

The other problem you will face is that books specifically about a distribution leave off about the level you have got to now. I always found them a disappointment, and they only talk about one particular set of graphical tools. So for example a book about Mandriva/PCLOS would only have marginal application to Fedora or Ubuntu. That means that general purpose books - like Linux in a Nutshell - concentrate on the command line.

Always look at the date a book was published. There is one in the O'Reilly series on Fedora but it was published in 2006. Not long ago, but it will not mention NetworkManager among other things. The linux scene has changed a lot in two years.

It also means that a book like Fedora® 8 and Red Hat® Enterprise Linux® Bible by Christopher Negus, which is from another series I quite like is going to be out of date in six months time.

One resource I would recommend to you is Wikipedia.

Look at its page for NetworkManager:

http://en.wikipedia.org/wiki/NetworkManager

That's about what I would be expecting you to see by the way, at least one network identified.

Lot's of links there as well to more information and it's the same about almost aspect of Linux you care to mention.

I've found that there is more about computing on the internet than almost any subject, and the links there will probably give you more up to date information than any book.

If you do go for books though, one final thought, I've never found one that told me the whole story so when I learned that way I had several on any subject and dipped in and out of them.

Good luck with the DVD, I hope you can take the time to tell here how you get on.

@bbfuller
Thanks for the lovely detailed tip!I agree tht most of the things are available on internet in a better way,let it be learning a language...the only reason i wanna refer a book is bcoz it gives u a discipline to learn smthing...i m expecting tht while learning linux,starting from the scratch continuty is VERY necessary!bcoz incase i learnt smthing in wrong order,not only it wud spoil my concepts but also my linux distro!!

And yes,i wanna learn linux,not anyone of the distro focussed...its just tht Fedora is my 1st distro,so i was hoping i wud be able to understand linux better thru it...but now i m looking for tutorials on net,only thing is,i dont know where i'll get a place on net where i'll be taught a in the correct order!

i just hope DVD works out for me! anyways,thanks bbfuller,u hv been reallllyyy helpful!thanks!

Hey bbfuller,

Guess you getting me wrong at some place. I do have my network secured and the commands I used in my earlier post were the ones I used to get on the secured network.

I take keen interest in security and hacking methodologies and have been involved in quite a few projects myself. But, still a newbie to wireless security as its just been a few days that I got wireless!

I am inserting here my views on your post. Firstly, WEP was a standard dropped long back, replaced by WPA and WPA2; because WEP sends out the SSID in clear text over the air, which enables things like AirSnort and AirCrack to break open wireless networks in a short time. Also, these make use of the AirCap Product Family. And its easy to do man in the middle attacks on wireless.

Quote:
Secondly, you can determine the unique MAC address of your wireless card(s), enter those in your wireless access point and tell it only to accept connections from cards with those identities.
Again, MAC Spoofing is easy and you can sniff off the MAC addresses.

Quote:
The third concerns the name you give the access point to broadcast so that you can pick it from a list on your machine, either in NetworkManager or its equivalent on Linux or the Windows ZeroConf Service Discovery in Windows - or the Network Card manufacturers utility. That broadcast identity is called the SSID. It can be seen as a security weakness broadcasting that name as it easily alerts any hacker as to the existence of your network.
Yes this is no doubt the best option. And everyone should go for it.

And bbfuller we can sure discuss security and learn!

Hello infinity99

Agree with all that you say.

Which is why I said:

Code:
Given a determined hacker I understand none of those prevent your network being hacked in 10 minutes.
Hiding the SSID can be a problem though in Fedora 8 as the earlier versions of NetworkManager wouldn't connect if it was hidden.

It's a problem if someone does an install from disc and wants to set up their wireless to update the system.

Hello ak_k80

It's never been a problem for me so I wasn't aware of that particular fix.

Thanks for bringing it to my attention.

Hello ak_k80

I suspect that you are using a root account that does not contain all of roots privileges.


If you use:

Code:
su
from the command line then you get root privileges but only in a limited number of areas.

If you want full root rights then try the command:

Code:
su -
That's a space and a minus sign after the su.

Type:

Code:
gedit
at the root command prompt to bring up the editor with full root rights and try editing the file from there.
