SSHd Pubkeyauthentication causes disconnections #112

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Install FreeBSD 8.2-PRERELEASE
2. Install shellinabox 2.10 from FreeBSD ports
3. Configure SSHd to use public key authentication
   - Edit /etc/ssh/sshd_config to contain:
     - PubkeyAuthentication yes
     - AuthorizedKeysFile      .ssh/authorized_keys
     - PasswordAuthentication no
   - Restart SSHd

What is the expected output? What do you see instead?

Expected: A prompt for an ssh key file to authenticate a user either before or 
after entering a username into shellinabox prompt

Seen: As soon as enter key is pressed after typing username a message saying 
"Session closed." is given and a connect button appears on screen.

What version of the product are you using? On what operating system?

shellinabox version 2.10
FreeBSD 8.2-PRERELEASE (although I doubt it will matter but I can't test on 
anything else)

Please provide any additional information below.

I use public key authentication into my SSH server to add additional security 
since I see regular brute force attempts to access my server so disabling this 
is not an option. I'm hoping shellinabox will be a viable solution for 
accessing my system from a system that doesn't allow me to install a SSH client.

I should add that I confirmed that this is the issue by changing my 
/etc/ssh/sshd_config entry for "PasswordAuthentication no" to 
"PasswordAuthentication yes" and using shellinabox without issues, of course 
this allowed me to connect using PuTTY without my private key as well.
