Core Tunnel - ProxyCommand with other ssh connection

[yang (Yang.Y)]

Actually, the workflow can be simplified if use ProxyJump option:

Jump Hosts -- Passing Through a Gateway or Two

It is possible to connect to another host via one or more intermediaries so that the client can act as if the connection were direct. The main method is to use an SSH connection to forward the SSH protocol through one or more jump hosts, using the ProxyJump directive, to an SSH server running on the target destination host. This is the most secure method because encryption is end-to-end. In addition to whatever other encryption goes on, the end points of the chain encrypt and decrypt each oth…

Core Tunnel can read options from ~/.ssh/config:

Use system default `ssh_config` and `known_hosts` configuration

By default, Core Tunnel uses configuration files in its own container folder: # known_hosts ~/Library/Group Containers/E78WKS7W4U.io.coressh.ssh/.ssh/known_hosts # ssh_config ~/Library/Group Containers/E78WKS7W4U.io.coressh.ssh/.ssh/config This works very well in most of cases. But if you have a lengthy ~/.ssh/config or /etc/ssh/ssh_config, or have StrictHostKeyChecking set to yes and use ~/.ssh/known_hosts, /etc/ssh/ssh_known_hosts as the only source data trusted host keys, you may want to u…
