Citrix ADC MPX
secure shell access with public key encryption on each appliance.
Citrix ADC features can also use SSH key based authentication for internal communication when the
internal user is disabled (by using the set ns param ‑internaluserlogin disabled command). In such
cases, the key name must be set as ns_comm_key.
To set up access using SSH keys, you must generate the public‑private key pair on a client and copy
the public key to the remote Citrix ADC appliance.
Generate the keys and connect to a remote Citrix ADC appliance by using SSH keys
1. On a client (Linux client or a Citrix ADC) change the directory to /root/.ssh.
cd /root/.ssh
2. Generate the public‑private key pair.
ssh-keygen -t <key_type> -f <optional_key_file_name>
Example:
To create an RSA key with default file name.
ssh-keygen -t rsa
3. Press ENTER when prompted for a file name for the key pair.
Note:
• If you update the default file name for the key pair, use the new name instead of the default
name in the rest of this procedure.
• If you want to disable the internal user login, use “ns_comm_key” as the file name for the
public‑private key pair.
4. Press ENTER two times when prompted for a passphrase.
Note: If the client is a Citrix ADC appliance, move the private key file to a persistent location such
as the subdirectories of the /flash and /var directories.
5. Log on to the remote Citrix ADC appliance from the client by using FTP, and perform the follow‑
ing:
a) Change directory to /nsconfig/ssh. At the prompt, type:
cd /nsconfig/ssh
b) Use the binary transfer mode to copy the public key to this directory.
bin
put id_rsa.pub
