Hello, I am testing ssh with occasional network disconnection between server and client during these days. I found ssh sometimes hangs if the disconnection happens after the connection is established but before ssh_exchange_identification completes. The ssh configuration files show that both client and server alive options are set. In /etc/ssh/ssh_config: # Send keepalive messages to the server.

From: Maxime Rey <maximejeanrey at gmail.com> Hello, I've discovered an issue with sshd when it's configured to use the SSH agent alongside multiple host keys. Specifically, this problem happens during the hostkeys-prove-00 at openssh.com request, when the server attempts to demonstrate ownership of the host keys by calling the agent. The issue occurs because, while processing the

I see that support for AuthorizedKeysCommand has been added. The arguments supplied to the command is just the authenticating user. Can we add the SSH connection details (ie. source and destination IPs and ports) as well? This command seems to be the idea way of requiring one set of credentials from inside an organisation (say the user's own authorized_keys file) and another set from outside
