    Sorry, we haven't been able to tackle this one yet, but it's still an open entry we're looking into.

      Hello,

      One of our developers dug into this a bit and didn't run into the issue like I did. As a quick test, if you update to the latest versions of PuttyGen, Pageant, and Putty, does this issue reproduce with a newly generated ppk keypair? If so, would it be possible to email us that key pair to support@scootersoftware.com (Along with a link back to this forum thread for our reference)?

        Perhaps the problem is that your key is DSA ?

          I don't know if this helps, but I noticed in the log that Beyond Compare 4 tries to do Keyboard interactive authorization first then does Public key agent authorization.

          Code:
          4/9/2020 8:17:15 PM Connecting to SomeServer
          4/9/2020 8:17:16 PM Server key [DSS 1024 lots of hex stuff]
          4/9/2020 8:17:16 PM Trying stored password for keyboard-interactive authentication
          4/9/2020 8:17:17 PM Keyboard interactive authorization failed.
          4/9/2020 8:17:18 PM Keyboard interactive authorization failed.
          4/9/2020 8:17:18 PM Public key agent authorization successful.
          4/9/2020 8:17:19 PM Server software: OpenSSH_6.0
          4/9/2020 8:17:19 PM Compression: none

          4/9/2020 8:17:19 PM MAC algorithm: hmac-sha2-512
          4/9/2020 8:17:19 PM Connected to SomeServer port 22

            Hello,

            Is that log using Putty's Pageant or a stored key within BC4? For within BC4, we've found a recent issue with OPENSSH Private Keys, and the key needs to be regenerated as RSA:
            http://www.scootersoftware.com/suppo...vatekey_compat

            Or the OpenSSH Key can be converted to PPK using PuttyGen.

              I'm using Pageant and it was a key created by using PuttyGen

                TatayMo,

                What Linux distribution is the server running (Ubuntu 14.04, Debian 8, etc)?

                Is it using the default /etc/ssh/sshd_config for the Linux distribution, or is it customized? If it's customized, please post it here or email it to support@scootersoftware.com with a link to this forum post.

                  Actually the server is on IBM AIX version 7.1. The sshd_config is below. I'm assuming it is a customized version. Please let me know if there is anything else you guys need to get to the bottom of this.

                  Code:
                  Protocol 2
                  LoginGraceTime 3m
                  PubkeyAuthentication yes
                  PasswordAuthentication no
                  ChallengeResponseAuthentication yes
                  UsePAM yes
                  X11Forwarding yes
                  X11DisplayOffset 10
                  X11UseLocalhost yes
                  Subsystem sftp /usr/sbin/sftp-server
                  DenyUsers XXXXXXXXXX
                  DenyUsers XXXXXXXXXX

                    I'm sure this issue is low on your priority list since there is a workaround, but is there any update for this? Anything else you guys need from the community to get to the bottom of it?

                    Thanks as always for your wonderful program.
