Much like a few recent posts, I am trying to get key auth working. In
fact, I've done it several times before, but I can't remember how I got it
to work. I'm sure that I'm missing something simple, so I'll post the
entire process that I use.
BTW, will messed up DNS cause it to use passwords instead of keys? Empty
passphrases wont mess it up, will they? (I'm only using empty ones for
testing).
(Openssh 2.9p2 & Redhat 7.0 on both sides)
NOTES: - box that you want to log INTO, is SERVER.
- box that you want to run ssh or scp FROM, without using password,
is CLIENT
#FROM CLIENT:
#generate key (once), use defaults (rsa1, .ssh/identity, no passphrase, etc.)
ssh-keygen
#copy public key to server
scp .ssh/identity.pub SERVER:/root/CLIENT.identity.pub
#start ssh-agent the correct way.
eval `ssh-agent`
#tell agent about our private key
ssh-add .ssh/identity
#FROM SERVER:
#allow public key, (does NOT go in authorized_keys2 file)
cat CLIENT.identity.pub >> .ssh/authorized_keys
That is the process I do to setup key auth. What is it missing? Here is
what I get when I test it:
(Of special note, IMHO, is:
debug2: userauth_pubkey_agent: no keys at all
debug2: userauth_pubkey_agent: no more keys
debug2: userauth_pubkey_agent: no message sent
)
Thanks for any light you can shed!
