Hello AragonX,
I will add these steps to the list:
- Only allow ssh V.2

I'm pretty sure this is the default.  I haven't need to make this change
since FC2 I think.

- Deny root ssh logins

This was implied by "only allow me to logon".  What I should have written
is "Only allow my account to logon".  lol

- Allow only ssh login with pub/priv keys and secure your priv key on
a encrypted filesystem on a USB key

This is a great idea but I'm unable to implement it.  Many of the machines
I end up using don't have USB.  :(

-Turn off all unneeded services
- Remove all unneeded binaries

Yes, I will add "Install only needed apps."  I do this anyway but I should
list it.

- If you need to access the server from outside your privatenet use
ipsec, openvpn or something related.

SSH is not enough?  I only need shell access remotely.

- If data integrity is of interest use a journalized filesystem for
both metadata AND data (by default ext3 put only metadata in the
journal), LVM and RAID5 and pay attention to SMART

Humm.  I'll have to research this one.  I was not aware of that limitation
for EXT3.

It's what I think at the moment. Some of these steps seems really
obvious but peoples tend to forget obvious things sometime.
Take care,

Thank you for the tips.
