<br>
Again, and th<font size="2">anks for your time. Well</font>,
what I tried to do, without success was the following;<br>
I downloaded two filesystems from the proposed URL, and
also a kernel from the same page based on what
</font><font face="Courier New" size="2">Mr. Joao proposed.
Kernel version was 3.9.6 and both of the filesystems was
UML.<br>
<br>
Then after extracting using bunzip2 and giving executing
permissions on the files, I issued the following commands;</font><i><font

<br>
<b>./kernel32-3.9.6 ubda=./BusyBox-1.13.2-amd64-root_fs

faults, was the following;</font><i><font face="Courier New"><br>

<tt><br>
There are a few improper steps in the procedure you are reporting:<br>
</tt>
<ul>
<li><tt>You also downloaded a kernel binary, but I don't see the
reason for that, given that your intention is to update
filesystem packages.</tt></li>
<li><tt>Your invocation fails because the 'mem' argument usually
requires some suffix indicating the unit (usually 'K' or 'M').
In the absence of this suffix, the specified amount is
intended in bytes, and 256 bytes is far too low for any UML
instance to start up.<br>
Another reason is that you are running a 64-bit filesystem
image on a 32-bit kernel.<br>
</tt></li>
<li><tt> Even if you wanted to replace the kernel, you should not
have invoked it directly if you intended to use it with
Netkit.</tt></li>
</ul>

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

Netkit offers all these features, including nmap, out of the box.

<tt>Hi,<br>
<br>
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!

<tt><br>
Yes, most networking-related packages are already in.<br>

In addition, if I want to upgrade any of the existing

</tt></div>

<tt><br>
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.<br>

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.<br>
</tt></div>
</blockquote>
<tt><br>
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.<br>

And, last thing, I cannot find any link for

<tt><br>
I guess these the download links you are looking for can
be found in this page: <a moz-do-not-send="true"
href="http://fs.devloop.org.uk/" target="_blank">
http://fs.devloop.org.uk/</a>.<br>
Please consider that usage of these filesystem images with
Netkit is unsupported and may result in unpredictable
behaviors and/or reduced functionalities.<br>

<div bgcolor="#FFFFFF"><tt>Hi,<br>
<br>
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.<br>
<br>
Which package(s) are you interested in
updating/installing?<br>
<br>
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:
<a moz-do-not-send="true"
href="https://github.com/kartoch/netkit-uml-filesystem"
target="_blank">https://github.com/kartoch/netkit-uml-filesystem</a>.
Depending on your needs, rebuilding the
image from scratch using this system may
be a way to go.<br>
