I have a 12.10 server setup in a virtual machine with its network set to bridged (essentially will be seen as a computer connected to my switch).
I installed opensshd via
apt-get and was able to connect to the server using putty with my username and password.
I then set about trying to get it to use public/private key authentication. I did the following:
- Generated the keys using PuttyGen.
- Moved the public key to /etc/ssh/myusername/authorized_keys (I am using encrypted home directories).
Set up sshd_config like so:
When I connect using putty or WinSCP, I get an error saying No supported authentication methods available (server sent public key).
If I run sshd in debug mode, I see:
PAM: initializing for "username" PAM: setting PAM_RHOST to "192.168.1.7" PAM: setting PAM_TTY to "ssh" userauth-request for user username service ssh-connection method publickey [preauth] attempt 1 failures 0 [preauth] test whether pkalg/pkblob are acceptable [preauth[ Checking blacklist file /usr/share/ssh/blacklist.RSA-1023 Checking blacklist file /etc/ssh/blacklist.RSA-1023 temporarily_use_uid: 1000/1000 (e=0/0) trying public key file /etc/ssh/username/authorized_keys fd4 clearing O_NONBLOCK restore_uid: 0/0 Failed publickey for username from 192.168.1.7 port 14343 ssh2 Received disconnect from 192.168.1.7: 14: No supported authentication methods available [preauth] do_cleanup [preauth] monitor_read_log: child log fd closed do_cleanup PAM: cleanup
Why is this happening and how can I fix this?
