SSH
214 IOLAN SDS/SCS/STS User’s Guide, Version 3.6
Users Passing Through the IOLAN Using SSH (Dir/Sil)
This scenario applies to serial ports configured for the Terminal profile and are required to login to
the IOLAN. The user’s service is set to the SSH protocol, therefore, users first log into the IOLAN
and then are connected to a specified host (configured for the user when
User Service SSH is
selected) through an SSH connection. Lynn and Tracy automatically connect to the HR Server and
Dennis automatically connects to the Development Server via SSH through the IOLAN. All the SSH
negotiation is being done between the IOLAN and the target servers, therefore, the following keys
need to be exchanged:
z Download the SSH Host Public Key to the IOLAN for each of the hosts that the IOLAN is
connecting to.
z Download the SSH User Private Key for each user whose User Service is set to SSH .
z Copy the SSH User Public Key to the host that the user is connecting to (this is done outside the
scope of the IOLAN).
