Enabling The Stelnet Server; Enabling The Sftp Server - HP FlexNetwork 10500 Series Security Configuration Manual

•
SSH supports locally generated DSA, RSA, and ECDSA key pairs only with default names.
•
To support SSH clients that use different types of key pairs, generate DSA, RSA, and ECDSA
key pairs on the SSH server.
•
The SSH server operating in FIPS mode supports only RSA and ECDSA key pairs. If both RSA
and ECDSA key pairs exist on the server, the server uses the ECDSA key pair.
•
The public-key local create rsa command generates a server key pair and a host key pair for
RSA. In SSH1, the public key in the server key pair is used to encrypt the session key for secure
transmission of the session key. Because SSH2 uses the DH algorithm to separately generate
each session key on the SSH server and the client, no session key transmission is required.
The server key pair is not used in SSH2.
•
The public-key local create dsa command generates only a DSA host key pair. The key
modulus length must be less than 2048 bits when you generate the DSA key pair on the SSH
server. SSH1 does not support the DSA algorithm.
•
The public-key local create ecdsa command generates only an ECDSA host key pair. SSH1
does not support the ECDSA algorithm.
Configuration procedure
To generate local key pairs on the SSH server:
Step
1. Enter system view.
2. Generate local key pairs.

Enabling the Stelnet server

After you enable the Stelnet server on the device, clients can log in to the device through Stelnet.
To enable the Stelnet server:
Step
1. Enter system view.
2. Enable the Stelnet server.

Enabling the SFTP server

After you enable the SFTP server on the device, a client can log in to the device through SFTP.
When acting as the SFTP server, the device does not support SFTP connections initiated by SSH1
clients.
To enable the SFTP server:
Step
1. Enter system view.
2. Enable the SFTP server.

Remarks
N/A
By default, no local key pairs
exist.
SSH supports only the secp256r1
and secp384r1 keywords for the
ECDSA algorithm.
Remarks
N/A
By default, the Stelnet server is
disabled.
Remarks
N/A
By default, the SFTP server is
disabled.
