Knoppix 6.3 Live CD Wired Connection

[jaques1]

I'm trying the latest Knoppix 6.3 Live CD distributed with Linux Magazine Issue 113 but cannot connect to the internet via my normal wired eth0 connection as used in Fedora 12/Win XP/other Linux Live CDs.

A pointer to a simple How-to would be much appreciated.

[dahveed3]

Well, its not out yet. On their website it says the US release of issue 113 is somewhere around March 15 if I recall.

And I believe you need to subscribe or buy the issue at a store (I think Borders carries them). I don't think they offer DVD downloads from the net.

Be patient. I'll be looking for the issue at my local shop. In the meantime we do have the just release 6.2.1 DVD. And if you want a CD, as you state, you'll only have 6.2.1 available as that LinuxMag special 6.3 is a DVD, not a CD.

Some confusion here. I already have the Knoppix 6.3 Cover DVD sent out with Linux Magazine Issue 113 and I've installed the OS on an 8MB USB stick as detailed on page 33 of the mag.

Everything works fine _EXCEPT_ I can't connect to the internet via my usual wired eth0 ADSL2 Modem Router connection.

Any help on how to achieve a wired connection would be appreciated.

Well, you're finally giving some network information (although not enough). I ignored the previous post because you didm't bother to tell us anything about the network that you were trying to get this running on.

Assuning that you really do have a router, please post:
1. the output of ifconfg
2. more network details, including hardware models and topology,including any info on the NIC.
We still may not be able to help you, considering that your post was the first that I ever heard of a 6.3 release, but we sure can't help you without knowing what you are trying to connect through.

I started a thread (http://www.knoppix.net/forum/viewtopic.php?p=122588) in News about 6.3

I think I may be having the same problem; when I try to use the wired ethernet connection at a location where I have been successful in the past under Windows on the same hardware (Gateway MX6214, 2GB RAM) - it just doesn't see the Ethernet connection. Weird! Knoppix has always been fine with that on earlier versions (maybe something's not in the hardware DB? See below.) FYI, the setup there is a BellSouth/ATT DSL modem/wireless router; I grab an Ethernet line in one of the lesser-used offices to hook up as I don't have the password for the router and it's impolite to break in. Until now, it didn't seem worth bothering about, but perhaps it's useful in this context.

Thanks for the replies.

I'm using my wired eth0 ADSL2 modem router connection on Fedora 12 to post this as all my attempts to get a connection on Knoppix 6.3 have failed.

Output from "ifconfig" shows no eth0 data only lo data so it doesn't seem eth0 is recognised.

The Network Manager Applet 0.7.99 task bar icon shows a red cross alongside it. When Editing A Wired Connection any attempt to input a MAC address greys out the Apply box so the settings cannot be applied.

I cannot get my ADSL2 modem router settings page to display on Firefox or Chrome.

I've reported the problem to bugs@knopper.net as advised on page 32 of Linux Magazine 113.

And you still don't give us any detailed hardware info, like the output of lspci -v..
Quite often, it is possible to get around hardware detection/initiallization problems by either turning off parts of the automatic procedures or doing the initialization manually.

I ran lspci -v and it confirms that my hardware setup is a bogstandard Dell desktop which has hitherto connected automatically to the internet when using a live DVD/CD.

I also replicated the wired connection settings in my Fedora 12 copy of Network Manager Applet 0.7.98 in the Knoppix 6.3 copy of Network Manager Applet 0.7.99 without success.

Thanks for the help but IMHO the automatic creation of an internet connection on a standard Intel desktop is a pre-requisite in a modern Linux distro so I'll pass on Knoppix 6.3 for the present.

Hardly anyone would disagree with that, and of course the most sensible thing for you is to just pass it on.

What in my opinion is very little sensible of you, is that you won't give us the details about the failing configuration. That means nobody here gets the chance to go into the details, and, probably, the person who reads the bug report you filed does not have the corresponding hardware.

And your problem with your Dell machine is not typical for Knoppix 6.X, to say the least. I have myself run 6.X on six different Dell laptops, (built 1998-2009), with no wired network problem at all. Maybe I have even got your network chip up and running with 6.2.1 automatically. Maybe some serious bug is introduced in 6.3, maybe you have a damaged chip which Fedora manages to work around automatically. (Happened to me with an Inspiron 8100.) It would have been interesting, maybe important, to know, and Debian is mostly a community project, relying on volunteers and input form users like you and me.

I take your point about input to the community.

FWIW - I got my wired connection working today when I was on-site with the DSL system again. Basically, it seems that this Netopia-3000 adsl modem/router does not handle name service well. I knew from days of yore that the provider (BellSouth) runs a couple of "test DNS servers" and a quick Googling brought up the addresses (4.2.2.2 and 4.2.2.1) which I then forced into the connection preferences and voila! Perhaps this will fix the original problem for Jaques, or it's unrelated but might help someone else later on...

Thanks for the thought but my Billion ADSL2 modem/router seems to be perfectly conventional and handles automatic wired connections on this PC for WinXPPro SP3, Fedora 12 and Mandriva 2010. No doubt there's probably a simple explanation for being unable to get my Knoppix 6.3 USB stick to connect but it looks like it isn't going to be available any time soon.

Hmm- there's a Windows XP machine that connects okay on the same line that I used. I wonder what's different about Knoppix that it didn't seem to get name service there, but it did on numerous wireless connections. :o

That got me thinking: so I booted my USB stick Knoppix 6.3 on my EeePC901 (which normally runs WinXPHome and Moblin2.1) and plugged in a wired connection to the LAN2 port of my Billion ADSL2 modem router. Result: immediate internet connection.

What this proves I'm not sure but at least I can play with Knoppix 6.3 on the 901 for now. BTW it automatically loaded Compiz complete with spinning cube, wobbly windows and transparency. V nice.

I tried commenting out the lines

| allow-hotplug eth0
| iface eth0 inet dhcp

in file /etc/network/interfaces as suggested in the bug but still can't connect on my desktop PC.

I think I may be having the same problem; when I try to use the wired ethernet connection at a location where I have been successful in the past under Windows on the same hardware (Gateway MX6214, 2GB RAM) - it just doesn't see the Ethernet connection. Weird! Knoppix has always been fine with that on earlier versions

I've also had success with previous Knoppix versions running on my wired Internet connection via a router, but the V6.2.1 DVD I tried yesterday quickly with the default LXDE desktop, and today with KDE desktop, doesn't even find the Ethernet interface.

The GUI network configuraration tools (e.g. NetworkManager Applet 0.7.999) have everything grayed out, and in some places says that I am "Not allowed to make changes."

ifconfig - a just has something for "lo" -- no eth0 or eth1 like the older Knoppixes find.

dmesg | grep eth | less has no output, which must mean that the hardware detection phase doesn't find my network "card".

The machine is a Dell Dimension 2400, based on the Intel Brookdale-G i845G chipset, with a Broadcom 440x 10/100 Integrated Controller.

I'm primarily a Windows user who grabs a Linux live disc for the self-tuning Internet connection to judge Windows against. One of Knoppix's "claim to fame" has been the wide range of hardware that it automatically adapts to.

Is there a simple way, e.g., via "cheatcodes", to have it see my NIC?

[krishna.murphy]

I'd suggest disabling some of the hardware autodetection, in fact almost everything that's not essential (nousb nothis nothat, etc.) It may not do it, but what have you got to lose? I'd also suggest using a persistent store and a downloaded driver (using e.g. Windows to find the right one and get it on your hd.)

Hope that helps!

Hi All It's possible to connect to a wired network from Knoppix6.3 live dvd using the same workaround as was needed for Knoppix6.0 [this was fixed in 6.2 but seems to have relapsed in 6.3] - problem being that settings for autoeth0 in NetworkManager Applet are somehow locked and not editable - BUT - if you right click on network icon to R of panel and go to you are able to add a new connection - so go to IPv4 settings tab and enter IP, mask and gateway [press after each of these] for your connection and DNS entries below and then click on add - should connect automatically now to your new autoeth1. If not, left click on same connection icon and then click on Correction - for some reason DNS entries do not seem to go from NetworkManager Applet to /etc/resolv.conf where they belong - so you need to open this file as root and enter for each of your DNS servers [on separate lines] then save and should be able to connect to net - at least it worked for me BUT - I assume these settings will be lost between boots, at least if you just use Knoppix as live cd - there must be a way of unlocking autoeth0 as in Knoppix 6.2 - but how? Best wishes, John
