Indeed, it's wise to have the firewall up.
But what I tried to figure out, was if something real actually happened
to someone. Port scanning is indeed unpleasant to watch if you're
unprotected, but would something really happen if you dropped your
firewall? Would whoever scanned those ports attack a Linux computer?
Not that I volunteer to try that out myself. And still.

at least in the past - the risk was real.
when i first connected my computer to the internet via ADSL, and set up
firewall rules - i was surprised to see that i get many (hundreads) of
failed network connections from around the world.
what people do, is run software that scans complete address (IP)
ranges, and attempt to find exploitable services on them.
the solution, on my part, was to close down everything i could at the
firewall level, and try to keep the open services (e.g. the kernel
itself, ssh server, etc) updated. keeping things updated was annoying
with redhat - specifically the distribution updates - and is one of the
reasons i switched to ubuntu. i tend to keep to the LTS (long term
support - 3 years) versions of ubuntu - and try to be in long delay
after the latest distributions - after having the diss-pleasure of
upgrading too early to 8.04 (or something).

Hi,
Since my not-so-updated software versions became an issue in itself
(somehow I always get that) I wondered: Leave alone the unpleasant
feeling of knowing your computer *could* be exploited, are there any
real cases of attacks against personal, non-server Linux machines? The
need to protect a server or a shared machine is obvious. But when it
comes to a personal computer, is there any real life justification to
be
anything else than completely indifferent to those risks? Or can we in
fact take a kibbutz approach of leaving the door open, knowing that we
may invite someone to break in, but that doesn't really happen?
This is not a question about what can happen, but what really does.
And just to wrap up the original subject: I was reluctant to try
mail-notification, because my mail filters move around the mails as
they
arrive. So I suspected things would get messy using a tool that
apparently polls the mail box files directly.
Anyhow, my solution ended up to be the Gnome Integration add on. I also
installed Mail Tweak, which among others allowed me to set HTML + Plain
text as the default outgoing mail format.
