See Figure (4) for more details. Note that ssh.Dial calls ssh.NewClientConn, which is here and which starts with: SetDefaults in turn is here and contains: which first says that if the config's Ciphers is not set, it should use the defaults, and then immediately after that, filters away any string that's not in cipherModes. If you need help, please ask on our community forum. Cc: crance ***@***. On most systems, the SSH configuration file is /etc/ssh/sshd_config. It's worthwhile to emphasise that this keypair is ephemeral: it will only be used during the key exchange and disposed of afterwards. severity: INFO As Thomas Pornin outlines, if only a single integrity key is used, an attacker can replay a record the client sent back to the client and the client would consider it valid. I thought --insecure part should be okay. Sent: Monday, November 28, 2022 1:25:24 AM It feels like the issue is with client cert that comes through. One last thing remains before bulk data encryption can begin, both sides need to generate 6 keys: two keys for encryption, two initialization vectors (IV), and two for integrity. In this situation, you may have the same root issue as with connection timeout errors, but there are some additional things you can check: Some connectivity problems can be caused by firewall configurations.
