There is a jump host, called via ProxyCommand, to access some servers. In the .ssh/config file there is a
Host definition for each server and the command for the jumphost (with
%h coming from the Host configuration) :
Host myserver Hostname myserver.mydomain.net User technic port 22 ProxyCommand ssh -x -p 22 jumpuser@jumphost ssh -6 -p 22 -x %r@%h "nc localhost %p"
Accessing the jumphost and then issuing the
ssh <host> command works and prompt me to confirm the connection.
Then the following connections work fine even via jumphost.
If I instead try to connect directly via jumphost I get no prompt for authenticity confirmation and I just get a
key_load_public: No such file or directory Host key verification failed.
I use the following versions: OpenSSH_6.9p1 and LibreSSL 2.1.8.
Do I need to first make a manual connection (manual connection to jumphost + manual connection to server) to each server, in order to have them work correctly afterwards?
Or is there some setting for prompting me to confirm the connection even at the first connection via jumphost? (without upgrading OpenSSH)
