Hi other linode users.

I'm trying to setup my firewall, using FireHOL, but have a few questions:

I'm doing a: ip link show, which gives me this result:
1: lo: <LOOPBACK,UP,10000> mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop
link/ether 96:07:0c:24:c2:a9 brd ff:ff:ff:ff:ff:ff
3: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 1000
link/ether fe:fd:cf:c0:48:73 brd ff:ff:ff:ff:ff:ff

link/sit 0.0.0.0 brd 0.0.0.0
8: ip6tnl0: <NOARP> mtu 1460 qdisc noop
link/tunnel6 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00 brd 00:00:00:00:00:00:00:00:00:00:00:00:00:00:00:00


Anyone who can point me out what each network adapter is for?

Also, when using firehol i keep getting this message:

IMPORTANT WARNING:
------------------
FireHOL cannot find your current kernel configuration.
Please, either compile your kernel with /proc/config,
or make sure there is a valid kernel config in
/lib/modules/2.6.18.8-linode10/build/.config,
/usr/src/linux/.config or /boot/config-2.6.18.8-linode10

Because of this, FireHOL will simply attempt to load
all kernel modules for the services used, without
being able to detect failures.

Extremely old thread, but I, too, am interested in what the network interfaces are for (except for the obvious eth0 and lo, of course).
