It’s important to keep an eye on permissions within the.sshfolder.
Most SSH clients want the files to be mode
within this folder.
An example of a simple configuration is below.
As you might tell from the above configuration, this is about as basic as one can get.
By defining this connection, on the command line we can simply do the following.
The connection will usually prompt for a password, as an SSH connection should not be unprotected.
These are the preferred way to setup an SSH connection.
How do we tell our host configuration to use this file?
There are two new commands that we have introduced here.
Second, we have defined a tag namedIdentitiesOnly.
By default, SSH will walk through and try every identity file until it finds the right one.
Starting in SSH version 7.3 and higher, theProxyJumpcommand allows us to easily accomplish this.
As seen above, there are two servers here.
It’s worth pointing out that you really shouldmake sure your SSH server is locked down.
SSH Proxy Tunnel
What if you have the need to set up a SOCKSv5 tunnel?
Doing so is quite easy using the config file.
We are introducing three new commands here,DynamicForward,ControlMaster, andControlPath.
Finally, theControlPathsets the location of the actual socket file.
Conclusion
There is a lot of power in the SSH Configuration file.
As you could tell, the SSH config file makes defining SSH hosts easy!
