Note: If the server is running, this command also stops the server.
Configure User Keys
There are no specific commands to configure user public keys. User public key files must be transferred into the C4/c
CMTS/usr directory. The filename formats are:
<username>.pem for DSA PEM-formatted key type
<username>.pk2 for DSA SSH2-formatted key type
In case the system administrator does not have key management practices to follow, consider these for offline key
generation:
OpenSSL toolkit for PEM-formatted
OpenSSH suite, PuTTY suite, and Vandyke Software SecureFX/SecureCRT applications for SSH2-formatted
Configure the Control Server
To start, stop, or restart the server:
configure ip ssh shutdown no
configure ip ssh shutdown
configure ip ssh restart
Note: All clients are disconnected when the server is stopped or restarted.
Configure Max Clients
To adjust the maximum number of simultaneous client connections:
configure ip ssh max-clients <max-number>
The default is 0, which means the same as the maximum of 20.
Configure Connection Port
To alter the TCP port number that the server listens to for client connection requests:
configure ip ssh port <port-number>
