R21xx-HP FlexFabric 11900 Security Command Reference

145
• dh-group1: Specifies the key exchange algorithm diffie-hellman-group1-sha1.
• dh-group14: Specifies the key exchange algorithm diffie-hellman-group14-sha1.
prefer-stoc-cipher: Specifies the preferred server-to-client encryption algorithm. The default is aes128.
prefer-stoc-hmac: Specifies the preferred server-to-client HMAC algorithm. The default is sha1.
publickey keyname: Specifies the host public key of the server, which is used to authenticate the server.
The keyname argument is a case-insensitive string of 1 to 64 characters.
source: Specifies a source IP address or source interface to connect to the server. By default, the device
automatically selects the source IP address from the routing table. To avoid the communication failure
between the client and the server due to interface faults, use the specified Loopback interface as the
source interface, and either IP address of the two interfaces as the source IP address.
interface interface-type interface-number: Specifies a source interface. The interface-type
interface-number argument specifies a source interface by its type and number. The IPv6 address of this
interface is the source IP address to send packets.
ipv6 ipv6-address: Specifies a source IPv6 address.
Usage guidelines
When the server adopts publickey authentication to authenticate a client, the client must get the local
private key for digital signature. Because publickey authentication uses either RSA or DSA algorithm, you
must specify a public key algorithm (by using the identity-key keyword) in order to get the correct data
for the local private key.
Examples
# Connect an SFTP client to the IPv6 SFTP server (2:5::8:9) and specify the public key of the server as
svkey. The SFTP client uses publickey authentication. Use the following algorithms:
• The preferred key exchange algorithm is dh-group14.
• The preferred server-to-client encryption algorithm is aes128.
• The preferred client-to-server HMAC algorithm is sha1.
• The preferred server-to-client HMAC algorithm is sha1-96.
• The preferred compression algorithm between the server and client is zlib.

Username:
ssh client ipv6 source
Use ssh client ipv6 source to specify the source IPv6 address or source interface for the Stelnet client.
Use undo ssh client ipv6 source to remove the configuration.
Syntax
ssh client ipv6 source { interface interface-type interface-number | ipv6 ipv6-address }
undo ssh client ipv6 source
Default
The Stelnet client uses the IPv6 address of the interface specified by the route of the device to access the
Stelnet server.
