[Netkit.users] Cannot update install,programs

[E Spatharas]

Hi,

Again, and thanks for your time. Well, what I tried to do, without success was the following;
 I downloaded two filesystems from the proposed URL, and also a kernel from the same page based on what Mr. Joao proposed. Kernel version was 3.9.6 and both of the filesystems was UML.

Then after extracting using bunzip2 and giving executing permissions on the files, I issued the following commands;

 ./kernel32-3.9.6  ubda=./BusyBox-1.13.2-amd64-root_fs  mem=256

The output mentioning faults, was the following;

- /proc/mm...not found: No such file or directory
  - PTRACE_FAULTINFO...not found
  - PTRACE_LDT...not found
UML running in SKAS0 mode
Adding 14876672 bytes to physical memory to account for exec-shield gap
setup_physmem - mapping -14188288 bytes of memory at 0x0x9c00000 failed - errno = -12

Since I have too many issues I will try to make it easier for me. My first plan was to create a network lab with ipv6 nodes and then scan them using a tool. nmap was my first choise. Then I could make it more interesting creating ipv4 as well, complex routing etc.

Does any of you no a specific package that could offer just that kind of tools, network scanners and simple networking between nodes.

Regards,
Vag

Hi,

Hi,

Thank you for your quick reply Massimo. I am just experimenting, I didn't had any specific tool in mind. However, I can see inside packages list that many tools are already installed. I can limit my curiosity in those for the time. So it's very fine!

Yes, most networking-related packages are already in.


In addition, if I want to upgrade any of the existing tools I think that it gonna be smooth. Right?

It depends on the tool you want to upgrage. In most cases, the thing should be smooth enough or pull a reduced set of dependencies.


By the way, how am I installing the filesystem provided in your first link? I suppose that I have to delete my existing one, and follow the same steps again for installing using the downloaded filesystem.

You do not necessarily need to delete the existing filesystem image: just download one of the images from the suggested URL and save it somewhere on your disk. You can then instruct Netkit to use that image by setting the environment variable NETKIT_FILESYSTEM to point to the newly downloaded file.


And, last thing, I cannot find any link for downloading this. Sorry I feel embarrassed.

I guess these the download links you are looking for can be found in this page: http://fs.devloop.org.uk/.
Please consider that usage of these filesystem images with Netkit is unsupported and may result in unpredictable behaviors and/or reduced functionalities.

Regards,
Massimo

There's also the Devloop's repo http://uml.devloop.org.uk/index.html with a variety of kernel images and filesystems (several distros) for UML.

Of course they don't have the netkit's kernel specific patches, but I could use, for all of my networking scenarios, those images with no problem.

Regards.

Hi,

depending on the package you are willing to install, there may be a high number of dependencies that cause a major upgrade of the filesystem image. And the upgrade may fail because of some other "chicken-and-egg" conflicts in package releases.

Which package(s) are you interested in updating/installing?

In the meantime, you may want to consider that a very active Netkit user has independently updated the filesystem image build scripts and made them available here: https://github.com/kartoch/netkit-uml-filesystem. Depending on your needs, rebuilding the image from scratch using this system may be a way to go.

Regards,
Massimo

Hello netkit forum,

I recently installed netkit on my ubuntu 12.04 machine. I am able to connect to the internet using the tap interface. However, I cannot make update or to install any programs. It says that I need lib6 and other packages, but when I try to install any package, it it continually fails to do so.

Have you any idea?
Thanks, vag
