Problems with setting up SVN, WebDAV, Trac

[Faizan Kazi]

Hi all!
I was following this guide to install SVN, WebDAV and Trac on my new Ubuntu
9.10 clean install:
http://www.howtoforge.com/debian_subversion_websvn

however, when i get to this:

$ mkdir ~/.ssh/
$ cd ~/.ssh/
$ ssh-keygen -t dsa
(I press enter for all the questions asked in the above statement and go
with the defaults)

faizan at acer-laptop:~/.ssh$ cat ~/.ssh/id_dsa.pub | ssh
faizan at acer-laptop"cat - >> ~/.ssh/authorized_keys"
ssh: connect to host acer-laptop port 22: Connection refused

Doesnt matter whether i try "ssh faizan at localhost" or "ssh faizan at 127.0.0.1",
it gives me the same ssh connection error.

can you please guide me on how to fix ssh??  btw... the "Firewall
configuration" GUI from the System >> Administration menu tells me that the
firewall is off (by default). not that that should trouble me from accessing
"localhost" i assume.. :s

Thanks!!

Regards,
Fez
