ℝaphink asked:
In ssh_config, one can choose to export some environment variables to the host using SendEnv.
Is there also a way to force a given value for this variable, per host? For example, would it be possible to export variable $FOO with value bar only when connecting to host example.com?
My answer:
You can’t give a specific value for an environment variable in ssh_config, but you can certainly send the existing environment variable only to specific hosts.
Host example.com
SendEnv FOO
To complete the chain:
FOO=bar ssh [email protected]
Finally, the remote server must have the environment variable listed in AcceptEnv in its sshd_config.
AcceptEnv FOO
