I'm not sure, that should be working. Check /etc/init.d/network, /etc/hosts, and
/etc/hostname, if they're all correct then `/etc/init.d/network restart', if that
doesn't work try `/etc/init.d/network stop; ifconfig eth0 down; rmmod <your NIC
module>; insmod <your NIC module>; ifconfig eth0 up; /etc/init.d/network restart'.
Also, the new netbase is a subset of the old without libwrap0 and tcpd; likewise,
netstd is an empty package which depends on its old components. Package dependencies
should get everything you need automatically, but something might have slipped. Make
sure you have all of these in your new potato install.

The kernel is not packaged as "kernel", but as "kernel-2.0.36" or whatever. Do:
apt-get install kernel-image-2.2.13
and it will do what you need it to (including updating your /vmlinuz link and
pointing /vmlinuz.old to the old kernel, prompting you and running lilo to install a
new boot block if you like, prompting you to create a boot floppy, etc.). Or use
dselect, go to Select, and search for kernel-image using the / key, hit + to indicate
you want to install, and it will prompt you for dependencies and recommendations.
For SMP, you will need to build your own kernel. Use apt or dselect as above to get
kernel-source-2.2.13 (and dependencies/recommended packages).
You will probably want to get kernel-package, as it builds a coherent .deb package
with all of your modules, system.map, etc. which installs nicely and is easy to
remove. Here's how I do it:
1. cd /usr/src; tar xIf kernel-source-2.2.13.tar.bz2
2. ln -s kernel-source-2.2.13 linux
3. cd linux; make [x/menu]config [note: kernel-patch for i386 has the standard
debian .config, it might help to start with this; be sure to save .config for
future use]
4. make-kpkg kernel-image >& ../log-2.2.13 &
You can tail -f ../log-2.2.13 to watch its progress. When it's done, there's a new
kernel package in /usr/src, use `dpkg --install kernel-image-whatever.deb' to install
it (and update the boot block, make a boot floppy, etc.).
WARNING: You really should not get kernel-image and kernel-source of the same
version. You'll end up trying to install, e.g., 2.2.13 on top of 2.2.13, with
inevitable conflicts. Maybe the 2.2.12 image and 2.2.13 kernel.
Also note: uninstalling a kernel-image seems to be slightly broken, it might leave
dangling symlinks in /vmlinuz or /vmlinuz.old. Make sure you check and clean these
up if necessary before rebooting!
Finally: it's a good idea to make an alternate lilo startup possibility, in case your
new kernel doesn't boot. To do this, edit /etc/lilo.conf, adding a new entry triplet
which boots from /vmlinuz.old. Mine is attached.

Apt is a front-end to dpkg, which uses your preferred URL (file, ftp, http, etc.) to
get packages and dpkg to install them. Dselect is a front-end which can use apt or
other install methods to get packages and dpkg to install them. As a newcomer, it's
probably better to start with dselect, and when you get tired of going through the
menus for simple operations, then use the simple apt command line interface.
For example, getting the latest version info on every package there is is as simple
as
apt-get update
Having done that, you can upgrade everything in your system with
apt-get dist-upgrade
Powerful, isn't it? I don't think there's a counterpart in the RedHat world...
This is probably more than you asked for, but hope some of it helped!
