    Exclamation sftp doesn't work with ssh keys on opensuse

    I've been trying to connect to a remote server using an SSH key for authentication but there seems to be a bug in Beyond Compare where it doesn't even attempt to connect using the specified key. I'm certain this is a Beyond Compare issue as I am able to SSH into the server using the key without issue and nothing is being logged on the remote server when I attempt to connect using Beyond Compare. Upon connecting to the server it provides a username and password dialogue.

    I've set the profile up as follows (these profile settings are identical to a working OSX Beyond Compare installation):
    Protocol: SFTP (SSH2)
    Host: example-sub-domain.example-domain.co.uk [this is a fictional example]
    Port: 22
    Username: user [this is a fictional example]
    Password: [empty]
    Save password: [unchecked]
    SSH private key file: /home/user/.ssh/id-user [this is a fictional example]

    Beyond Compare is logging the following error:
    07/02/17 2:07:39 pm Connection closed.
    07/02/17 2:07:39 pm Connection failed: Connection lost (error code is 115)
    07/02/17 2:07:40 pm Connecting to example-sub-domain.example-domain.co.uk

    07/02/17 2:07:41 pm Invalid version

    Hello,

    What command line did you use to generate the key with this options/parameters? Example:
    ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

    The error you are hitting is an attempt to use the key, which, if it fails will then prompt for a password as a fallback authentication option if available.

    If you run ssh-add are there any keys in queue for adding on your system?
    If you regenerate a new key, does this new key work with BC4? To help determine if there's something specific about this key that we're having trouble with.

    I generated a new key myself for the test system, ran into similar errors but found that the ssh-agent was already running in a bad state. This forum thread helped me get things running with the terminal's ssh command, after which my key worked in that test machine and any others I tested.
