Cluster like SSH client with hop definition capability
I work in a huge farm of servers (to me at least!) where I have up to 60 servers in one of my branches to connect to. You can not directly see these 60 servers, you have to login into a jump/hop server first and from that machine, you can see the 60 nodes to login to.
Because these nodes are the same, I installed Cluster SSH in the jump server, then I have to "ssh -X" into the jump server and then open terminal for all of them at once.
I was wondering if we have any kind of Cluster SSH like app that one can define a jump server (or even multiple jump servers) for. This way I didn't have to install anything on my jump machine.
