yet another "passwordless ssh" question


Ok. So I am trying to setup a passwordless ssh by doing (on the server):
1. ssh-keygen -t dsa
2. copying id_rsa.pub to authorized_keys

Of course, it doesn't work. I am working on a big project, and I am the only person for whom this method hasn't worked (well, it worked for a while but somehow I broke it).

I revised several troubleshooting posts (and unsuccessfully tried them all). So, I ran the verbose ssh -vv user@server:
Quote:
If you get a line like this, not containing "publickey":
debug1: Authentications that can continue: password,keyboard-interactive
I do get "publickey" here.

Quote:
If you don't get a line like:
debug1: try pubkey: /home/user/.ssh/id_dsa
Then check "ssh_config" on the client and if it exists, remove "PubkeyAuthentication no" if it exists.
I don't get this line, but I do not have access to the ssh_config. And as I previously stated, all other users have been able to setup passwordless ssh'ing on the same server.

Quote:
If you still don't see that line then make sure that "~/.ssh/id_dsa" exists on the client.
If you get a line like:
debug2: we sent a publickey packet, wait for reply
Check that "~/.ssh/authorized_keys" exists on the server and contains a line the same as "~/.ssh/id_dsa.pub" on the client.
Yes, yes. All necessary files exist in both server and client.

Thanks for your help.

the usual gotcha is that the key files don't have the right permissions. the .authorizaed_keys file needs 0600 so that only you can read it, otherwise it logically makes a mockery of the security if anyone can read it...

Thx 2 all 4 the help.

Yep, ssh can be tricky when it comes to permissions. It ended up being that my home folder had writing permissions for the group, thus ssh would not allow me to configure passwordless mode because somebody could've copied my authorized_keys file (even though the file itself had the appropriate permissions).
