Ubuntu Networking :: Netrwork Manager Erasing Wep Keys
Apr 19, 2011
I am running Karmic on a Lenovo s10e. I have been trying to reconnect to some wep encrypted ap's. There have been recent changes to the routers. In some cases my mac is barred, also some have changed their mac as well. Typical behavior of network manager on failed connection is to ERASE THE WEP KEY.
I call this worse than a bug, I really get tired of typing in the same key over and over! I think there is a basic misunderstanding about what the software is supposed to do. Even if there an error in the key, having the old one there to edit would be a huge help. IN MY PROFESSIONAL OPINION, NETWORK MANAGER SHOULD NEVER, EVER ERASE THE WEP KEY. Typing in 26 hex digits (for a long key) is needless aggravation.
If I am doing something wrong, someone please tell me. My point still stands. Even if I am doing something wrong, THERE IS NO EXCUSE FOR ERASING THE WEP KEY.

For 9 days now I have been getting errors when trying to run Update Manager saying that ALL my keys are missing.
Code:

I don't know if this is a configuration issue or a hardware issue, but I have a Kinesis Advantage USB keyboard and for some reason the F3-F5 keys aren't responding as they used to. They don't respond to anything and, when I tried using F5 on Emacs, it said <XF86AudioNext> is undefined, so I guess it's a weird mapping problem.
Any idea how I could remap them to the original meaning?

I have two harddrives installed on my HTPC. I am using the smaller (120gb) to run the OS (kubuntu 10) the larger (1 tb) I want to use to store all of my media.
However....
The second hard drive has THREE linux Distros on it (from me testing and playing and making decisions) and I CANT figure out how to get them off.....
The hard drives are SATA and plugged in in the correct order.
I have tried fdisking and reformating which seemed to work, but when I boot it still asks me which OS i want to boot to.
Right now I am trying to zero out the hard drive by using ths
dd if=/dev/zero of=/dev/sdb
I typed that in as root about 15 minutes ago and hit enter. it hasn't said anything since. no command prompt or anythng. I am hoping it is working, we will see.

I'm running Debian (Squeeze) and I have a toshiba portege m700. It has five buttons on the front just under the screen, which are the only ones accessible when you flip the screen over into tablet mode. One of them is for rotating the screen, and another is for switching to external display. I want to remap the remaining three to control, alt and super so that I can use shortcuts with the stylusThe problem is, when I used showkey to find out the key codes, I found out that each button generates more than one key code:Button 1:
key 126 press >> super_r, although this is distinct from the actual super key (125)
key 7 press >> 6
key 7 release
key 126 release

I've had problems with my Ubuntu partition on my computer, so I have decided that I might have to format the partition or reinstall Ubuntu.
My problem is that I have files on my partition that I would like to save. I've tried every tool I've found that allows Ext2 to be read in Windows, but none of them work for me. The best I have gotten is that I would be able to see the folders in /, but that is it. I was wondering if it was possible to reinstall Ubuntu without having to erase the partition.

I am attempting to erase a directory called apps. When I run rm-rf apps it looks like it erases it for the moment. When I log back on to the server the directory is still there, though it is highlighted in green.

I have an external hard drive I use for backups. This drive has entire operating system on it(don't know which one, but I think it's intrepid), from when I did a complete backup eons ago. I have added new stuff since then. I tried to erase the system files on it, since they take up space and aren't likely from my current system. I don't run the drive all the time, only when I'm backing up files. The rest of the time, it's off. When I did this, I couldn't run any programs on my main computer( the bin directory was gone), and it wasn't in my trash on the main drive or the external drive. I tried re-installing without erasing my home directory on the main drive; it went okay, until I tried to open a file.
My /home apparently had nothing in it, so i downloaded my backup files, only to run out of room. The files were there; I just couldn't see them. I tried to open several programs, but was told I didn't have root access. Finally, I just reformatted the whole drive and re-installed everything. What I'd like to know is:1. How do I clear the junk from the external drive without hurting the main drive?
2. Why did erasing the old bin file on the external drive whack the same file on the main drive?3.Several times before, I have upgraded or re-installed xubuntu, leaving my home directory intact. The upgrade either can't find my files, or forgets half my settings. How can I keep my files and settings? I hate having to re-install everything from scratch each time I upgrade. I thought having a separate /home directory was supposed to protect all that.

I'm using windows 7 now and I want to install ubuntu as the main OS to the current C:drive(which has installed windows currently) but with keeping the data in other ntfs drivers(D:, E:, F: ) on my hard disk. I can't take backups of all data in other drivers and if that data erased with ubuntu installation I will face a very big problem in future. So how to install ubuntu 10.10 only for a one drive(c: drive) without erasing the data on other ntfs drivers? and I uses nvidia 8 series graphic card and are there any special things to follow to install it's official linux drivers(.run) or is it enough to use default drivers on ubuntu.

I am trying to install ubuntu 9.10 alongside windows on my laptop's harddrive. When I was going through the procedure it gave me the option of a guided partition of my harddrive... however there was an error. At this stage I unplugged my external harddrive because it's sometimess a bit dodgy and restarted the installation process. However everytime since that I have tried to install, it only gives me the option of erasing the entire disk or specifying the partitions manually

I've been running Lenny for quite a while and have always been plagued by strange CD writing/erasing errors in K3B. I also tried erasing my CDRWs using wodim from the command prompt but had erratic results there also. I was researching these problems on Google recently and finally found a solution as well as an explanation of the cause of all the difficulties. Go here [URL], do some reading and then download/install cdrtools-3.00 from the link on the main page. The package did all the work for me including updating the default programs in K3B - now everything works as it should. I sincerely hope Debian will reconsider the trouble-prone fork of the original cdrecord (wodim) and make Jorg Schilling's excellent cdrecord the package of choice for future releases of Debian.

GNU bash 3.1.17. I say there must be, in bash, a keystroke combination that does this: I type say, two words at the prompt. Then I press HOME. And now, holding down some control key, I press a key that erases from current cursor position up to the first blank (the space between the two words). If I am right, which is the key combination? You could as well refer me to the bash manual section where the different combinations, one of them a control key are listed.

Is it possible to mount a 2nd hard disk without erasing the data that is already on it? If so, what command must I enter. The system recognizes that the disk is there, I just can't access the data because it hasn't been mounted.

Using SSH all the time on my home network. I use ssh-keygen and ssh-copy-id to generate and then copy the key file. On one of my computers I've changed the default ssh port and see no way to copy the key without reverting the configuration to port 22 temporarily. This is not a big deal and would probably take less time than it has taken me to type this message.

I've been searching for a while in forums about the issue I'm facing but couldn't find anything clear, or at least my net search skills are pretty lame. I'm facing a problem with prompted user password in a SSH chain connection when using authorized_keys.
I have: (1) Client - (2) Server - (3) Testing machine (testing machine is connect to Server via usb network)I've created keys for Client and Server, and updated authorized_keys in host machines with the key values: Testing machine has Server public key, and Server has Client public key.Until now everything is fine, if I try to connect via ssh the user password prompt is not shown since public key is found in authorized_keys.
For example: from Client: Code: ssh server Works fine, no password prompt.from Server: Code: ssh testing_machine Works fine, no password prompt.But if try to do that from Client only: from Client: Code: client:$ ssh server Works fine, no password prompt.from Client: Code: server:$ ssh testing_machine Asks for password.Bellow the verbose output from previous ssh command:
Code: ssh -v root(at)192.168.100.2
OpenSSH_5.3p1 Debian-3ubuntu4, OpenSSL 0.9.8k 25 Mar 2009
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
