>Description:
The the following sshd_config in place, connecting as user 'testing' to the box gives a blank/empty terminal. Attempting to run
any commands yields an error and the session is dropped. In HEAD, this same scenario is handled with a message indicating the
current system only allows sftp connections.
>How-To-Repeat:
Protocol 2
Subsystem sftp internal-sftp
Match User testing
ForceCommand internal-sftp
X11Forwarding no
AllowTcpForwarding no
Use the above sshd_config and attempt to log in as user 'testing' via SSH, connecting as SFTP should work.
>Fix:
This problem does not appear in HEAD.
