I want to reach any of my server with only one SSH command.
My problem is that when I use "ProxyJump" or "ProxyCommand" the "IdentityFile" is searching for the key on my machine.

**Is there any option in the config to use a remote key for the next jump?**

I have common users starting from the second level of servers, lets call them "secondadmin" and "thirdadmin". Currently I can reach a server in a third level using two ssh commands like this:

```
myuser@first-server: ~/$ ssh -i ~/.ssh/id_rsa secondadmin@second-server
secondadmin@second-server: ~/$  ssh -i ~/.ssh/id_rsa thirdadmin@third-server

```

I want to emulate this behavior above and don't want to have separate users for everyone on these servers (for now).
I also don't want to copy the private keys of the admins to my or any other user's machine either if it's not necessary.
