13th May 2008 Update: I have removed the original contents of this post. Normally I would not remove the contents of any blog post; however, due to security reasons I did not want anyone to follow the instructions that were contained within the post. I have updated the information about creating passwordless SSH keys and moved it to my wiki, it is probably better off there anyway ;) See:
Sorry for any inconvenience this may have caused.

When I try to do this I get an error on the very first command
peng@foo:~$ ssh-keygen -t dsa -b 2048 -f ~/.ssh/id_dsa
DSA keys must be 1024 bits
Should I run it with 1024 bits or is there a trick to using 2048 bits?

BostonPeng, looks like something has changed since the Feisty. This used to work fine, I'll do some investigating and report back. Meantime, 1024 should be fine.

Cool. That's what I ended up using. And when people come here from my blog they'll see that's fine too.
Thanks for getting the word out to us on this one. I don't know that I would have realized what the advisory meant to me.

BostonPeng, I have just realised that this post was actually related to creating a key pair without a password and for use specifically with scripting. If this is what you are wanting to do then great, otherwise I would advise you to follow the instructions on the Ubuntu wiki.
I have updated the original post to link to the Ubuntu wiki. Sorry for any inconvenience.

Thanks for the correction. I'll recreate my keys with the updates I got this am and with the info on the wiki.
