Nice page, but it can be enhanced ;-)

* Copying the ssh pubkey to the remote server can be done in one step:
[1]

cat ~/.ssh/id_dsa.pub | ssh user@host \
"mkdir -p .ssh; cat >> .ssh/authorized_keys"

* If you use the default filename for your key, you don't have to give
the filename with every ssh call (or to use an alias):
ssh-keygen -t dsa -b 2048 # without -f filename
You can then login with simply
ssh user@host # without -i filename

* "no passphrase" isn't something I like...
