SSH Client sending environment variable

[rgillan]

Server side (ssh2) we are processing the session.on 'env' and using it to transfer required information to our server. This works well from a typical ssh command line. We are trying to create a ssh2 client passing the key information (working) but do not see any methods or ways to send the environment key/value to the server (to emulate the -o SendEnv=X_ENVIRONMENT_VARIABLE ssh option). Is this possible using the ssh2/client?

You pass them in the options object to shell() or exec() on the client side.

thanks, bit of trial and error and we are passing it correctly. We needed to have:
client.shell({"env":{"X_ENVIRONMENT_VARIABLE":"desiredvalue"}}, (error,stream) => {....
for it to work correctly

echo $X_LOGIN_IP not works.

@alanhe421 The server may be restricting what environment variables you can send. For OpenSSH servers, this is controlled by their AcceptEnv config option which by default allows nothing at all for security reasons.

Thank you very much. I just checked and confirmed that this was indeed the issue.
