PLEASE REPLY TO THE LIST AND NOT TO ME PERSONALLY! I am no expert, and
you will get much more authoritative help from the list at large! This
means that you should use "Reply-All" or whatever gmail uses. Then you
should tweak the addresses appropriately.

can you please confirm that you *do* have two network interfaces or not?

please confirm that you typed /etc/sysctl with an ell, not a number 1. Your
command above is a 1 and not an ell.

you should have received some response, like "command not found" if
you had actually used a one. if you have indeed issued "sysctl -p" and
not "sysct1 -p" and it appeared that nothing happened, then that means
that the command executed but had no variables to set. If there were
variables to set, it would echo those back to the console.

so let's rehash this. You need to instruct the kernel to not send so
many error messages so that you can begin to actually get some work
done. instead of mucking around with the existence or not of
/etc/sysctl.conf for the moment, lets just stop those messages with
this command, in a root console (the one you get when you use a
single-user boot).

echo "4 1 1 7" > /proc/sys/kernel/printk

then confirm that it successfully set the printk levels with

cat /proc/sys/kernel/printk

you should get those four numbers back as output.

That *should* turn off those messages for the current session. Until
we can figure out what happened to your sysctl.conf, you'll have to do
the echo above as root with every boot.

try it out and report back. also, please provide the output of

dpkg -l procps
