Greetings again, Martin

It looks like the mail is a little slow here, so our notes
are out of sync a bit.

It's hard to tell just how, but I think your 'install' has
gotten a little mangled. If you had a LiveUSB, like my own,
it would be easy to make a test to see if the basic
compressed image is intact and correct, using either testCD
or testDVD. These are built into Knoppix for this purpose.

Likewise, with poor-man installs, since these also use the
basic KNOPPIX compressed image, testCD and testDVD may also
be used there.

Once the system has been expanded and changed, this can no
longer be applied. I don't know if there is a test to verify
the basic integrity of your system at present.

My interest here is to dig into and understand if there are
deficiencies in any of the standard Knoppix elements.
I'm no firewall expert, but I'm pretty sure that Klaus K
has put a lot of work into this element and tailored it
especially for this OS and its applications.

I can tell you your comments don't describe the way the
Knoppix firewall seems to work for me, but seem rather,
more likely to describe a scrambled installation.

You may want to consider the LiveUSB approach rather than
any of the conventional installation methods for this and
a good many other reasons.

Perhaps some of our more experienced members of the forum
may have some more useful insight for you than this.
