== How to get wireless cards working with ndiswrapper ==
There are a couple of other guides around on this, but this should be a quick and easy way to get wireless cards working with Knoppix.

=== Loading ndiswrapper ===
Ndiswrapper is already in Knoppix, so you just need to get your windows xp driver loaded. You will need the .inf and .sys files. If you still have a driver cd for your card, you can probably find them there, or just download them from the manufacturer's website. Now you need to get those files onto your Knoppix machine and load them into ndiswrapper. If you copied them onto a flash drive, the command for ndiswrapper would look something like this:

# ndiswrapper -i /mnt/sda1/somefolder/drivername.inf

You can check to be sure the driver is loaded with

# ndiswrapper -l

If that told you the driver was loaded and the device was present then you can modprobe ndiswrapper

# modprobe ndiswrapper

Now your card should spring to life and will probably attempt to connect to any unsecured network nearby. If that is all you ask, then you are done! If you need security, read on.

=== Wpa_supplicant ===
If you need wpa security for you wireless card, then you need to set up wpa_supplicant. First you need to save your password in a file for wpa_supplicant using the "wpa_passphrase" command. Like this:

# wpa_passphrase essid password > /etc/wpa_supplicant.conf

Now start wpa_supplicant like this:

# wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf

You should now be connected to your secured network. You can check this with "iwconfig". You also should check "ifconfig" to see if your wireless adapter has received an ip address. If not, there is one more thing to do.

# pump -i wlan0

That should get you an ip address for wlan0. Substitute wlan0 for whatever the name of your wireless adapter is. Hooray! All should be well now!

Now start wpa_supplicant like this:

# wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf

That place is the '''[http://www.knoppix.net/forum/ forums]''', reached by clicking on the '''[http://www.knoppix.net/forum/ forum link]''' near the top of the Knoppix.net home page or this page. The forums are actually a much better choice for posting questions about the wiki too, as regular users see new forum posts each time they visit this website, but only see see changes to the wiki if they search them out.

Before posting a question in the forums it is advised to look at the different subjects the forum is sub-divided into and to read through some of the posts in the forum that best seems to fit your subject. You can also use the search feature to search the forums, you might find your question has been answered many times already with one or two simple keyword searches, and you will get a response much faster that way.

Also, before you post, try to pick the forum that is the best fit for your question, and use a meaningful subject line that relates to the problem. Don't use subject lines like "I'm new, help me". The forums would be a useless mess if everyone did that.

Bugs/4.0.2CD

2006-01-26T18:09:48Z

Firehawk256:

1)The 4.0.2 CD at boot says: Welcome to the KNOPPIX live Linux-on-DVD!

THIS IS THE CD AND NOT THE DVD AS IT DISPLAYS!

2) Boot Option "knoppix no{swap}" is getting ignored (at least on an SATA Harddrive with Linux Swap partition). !!! Knoppix will still use the swap partition !!!

3) if toram boot option is used, shutdown does not work. After X-windows exit, shell prompt appears, but system does not do shutdown. Also poweroff or shutdown commands have no effect at all.

3a) if toram boot option is used, "knoppix-terminalserver" NFS does not work. The client side will say "Permission denied by server" when trying to mount the exported "/cdrom" dir. Have attempted modifying/blanking hosts.allow and hosts.deny, fiddling with export options, flushing iptables, and changing permissions/owners on the exported directory. This function works flawlessly when booted from CD.

4) not sure this is new, but while customizing 4.0.2CD I encountered a problem involving hotplugging multiple usb-storage devices. If one is mounted, and another is plugged in, the first device often seems to move to a new device but the old mount remains. There seems to be some explanation of this behavior in /sbin/hotplug-knoppix. Comments therein suggests the problem goes back to 2002. It would be the nice and expected behavior if plugging new storage doesn't booger up existing mounts. Any explanation of the issues involved would be helpful as well.

5) Starting knoppix with boot option "knoppix desktop=xfce" initiates successfully xsession, sound can be heard but when loading xfce desktop computer returns to shell screen with message X Window xsession terminated with errors.
Tried on x40, within vmware. all other options boot up correctly (in regard to xsession...)
no errors in xfreelogs:
(WW) VMWARE(0): Failed to set up write-combining range (0xfa000000,0x1000000)
(WW) VMWARE(0): Option "DPMS" is not used
(WW) `fonts.dir' not found (or not valid) in "/usr/share/fonts/truetype".
Entry deleted from font path.
(Run 'mkfontdir' on "/usr/share/fonts/truetype").
(WW) The directory "/usr/share/fonts/latex-ttf-fonts" does not exist.
Entry deleted from font path.
(WW) The directory "/usr/X11R6/lib/X11/fonts/defoma/CID" does not exist.
Entry deleted from font path.
(WW) The directory "/usr/X11R6/lib/X11/fonts/defoma/TrueType" does not exist.
Entry deleted from font path.
(WW) Open APM failed (/dev/apm_bios) (No such device)

just tried this on a quite typical desktop machine. same behaviour. desktop xfce seems to be broken.

6) /usr/share/knoppix/profile contains files and directories (e.g. .gnupg .mozilla .nessus.keys .netscape) which are copied into /home/knoppix when the X session is started (see rsync commands in /etc/X11/Xsession.d/45xsession). However, these files are '''owned by root''', not knoppix! So files which knoppix does not have permission to read '''fail to get copied''' (e.g. .nessus.keys). Only found this out because I was trying to add a .ssh directory in there and wondered why it failed to get copied across at boot time ... a swift ''chown -R knoppix.knoppix /usr/share/knoppix'' before re-mastering the Knoppix CD fixes this.

If you follow the instructions on the [[Knoppix_Remastering_Howto]], the equivalent command would be ''chown -R 1000.1000 /mnt/hda1/knx/source/KNOPPIX/usr/share/knoppix''.

7) Knoppix 4.02 CD won't boot on an IBM Thinkpad I Series 1161-43u. It only
displays "Disabling IRQ 15" over and over. Knoppix 3.8 CD works fine.
* Have you tried any of the cheatcodes? Have you cross posted this issue to the forum? --[[User:Rwcitek|Rwcitek]] 22:16, 5 Nov 2005 (GMT)

8) Change read/write mode not working with bootfrom-cheat ---
If I start knoppix with "knoppix bootfrom=/dev/hdb1/KNOPPIX.iso", and then right-click "Hard Disk [hdb1]" on Desktop and choose Actions->Change read/write mode, I get this error after confirming the action: "The remount command failed. Maybe there is another process accessing the filesystem currently."
I can still remount this manually with "sudo mount -o remount,rw /cdrom2.loop"
This bug is also present in 4.0.2-DVD
* Possible workaround: create a swapfile /mnt/hdb1/knoppix.swp. Have you cross posted this issue in a forum? --[[User:Rwcitek|Rwcitek]] 22:16, 5 Nov 2005 (GMT)

9) Knoppix-terminalserver
* clients/hosts booting with etherboot ROM's fail, because of some bug in the etherboot.nbi, but I'm not sure. can't find miniroot.gz, ... and than vmlinuz
* /etc/resolv.conf which is symlink to /etc/dhcpc/resolv.conf is not updated even for the hosts which boot with a PXE ROM, running netcardconfig with dhcp yes does the trick. --[[User:bsd|bsd]] Mon Nov 7 05:30:02 UTC 2005

10) CD 4.02 do not use the USB 2.0 full speed mode.
The error is in the linuxrc in /boot/isolinux/minirt.gz The line
USB2="ehci_hcd.ko"
should be
USB2="ehci_hcd"

11) There seems to be something wrong with the hardware detection of several versions of knoppix (all Knoppix versions with kernel 2.6.x that I tried, including the latest (4.0.2)):
I've written a forum entry describing the problem: http://www.knoppix.net/forum/viewtopic.php?t=22343
To be more specific, the wrong driver for a family of network cards is being loaded (or that's what I think), causing knoppix to crash on boot, while trying to get an IP from DHCP.

12) mkbootfloppy doesn't work, possibly since 3.7. I made a forum post, with a rather ugly fix, here: http://www.knoppix.net/forum/viewtopic.php?t=22949
It seems the problem is that if the second boot floppy is formatted as a 1722 KB disk then knoppix thinks the disk is corrupt at boot time. If the second boot floppy gets formatted as a 1440 KB disk then everyting is fine.
