Telnet/SSH
Use the Telnet or SSH protocol to connect to any AirLink device and send AT
commands.
A secure mechanism to connect remote clients is a requirement for many users.
In ACEmanager, Secure Shell (SSH) is supported to ensure confidentiality of the
information and make the communication less susceptible to snooping and
man-in-the-middle attacks. SSH also provides for mutual authentication of the
data connection.
For information on configuring an AirLink device to use SSH PAD mode, see SSH
PAD Mode on page 22.
