I googled and tried for over 30 minutes, but I didn't find this usecase and thus didn't manage to get it working. Probably I used the wrong keywords.
Using ssh -i privkey user@jumphost.org works. ssh asks for password of privkey. After entering password for privkey, connection is established.
Using
ssh -i privkey user2@targethost.org -J user@jumphost.org ssh prompts for password of user@jumphost.org. After entering password for user@jumphost.org password for privkey is asked and connection is established.
I'd like to enter the password for privkey when establishing the connection once and then using it for both servers. What am I doing wrong?
using -v option for ssh it looks like ssh is ignoring the -i option for jumphost.org
