R3303-HP HSR6800 Routers Security Command Reference

367
• sha1-96: Specifies the HMAC algorithm hmac-sha1-96.
prefer-kex: Specifies the preferred key exchange algorithm. The default is dh-group-exchange in
non-FIPS mode, and is dh-group14 in FIPS mode.
• dh-group-exchange: Specifies the key exchange algorithm diffie-hellman-group-exchange-sha1.
This keyword is not available in FIPS mode.
• dh-group1: Specifies the key exchange algorithm diffie-hellman-group1-sha1. This keyword is not
available in FIPS mode.
• 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 sha1-96.
Usage guidelines
When the client's authentication method is publickey, the client must get the local private key for digital
signature. In non-FIPS mode, because the publickey authentication uses either RSA or DSA algorithm, you
must specify an algorithm (by using the identity-key keyword) in order to get the correct data for the local
private key.
In non-FIPS mode, the default algorithms are as follows:
• The algorithm for publickey authentication is dsa.
• The preferred client-to-server encryption algorithm is aes128.
• The preferred client-to-server HMAC algorithm is sha1-96.
• The preferred key exchange algorithm is dh-group-exchange.
• The preferred server-to-client encryption algorithm is aes128.
• The preferred server-to-client HMAC algorithm is sha1-96.
In FIPS mode, the default algorithms are as follows:
• The algorithm for publickey authentication is rsa.
• The preferred client-to-server encryption algorithm is aes128.
• The preferred client-to-server HMAC algorithm is sha1-96.
• The preferred key exchange algorithm is dh-group14.
• The preferred server-to-client encryption algorithm is aes128.
• The preferred server-to-client HMAC algorithm is sha1-96.
Examples
# Connect to the SCP server 192.168.0.1, download the file remote.bin from the server, and save it locally
to the file local.bin
<Sysname> scp 192.168.0.1 get remote.bin local.bin
sftp
Use sftp to establish a connection to an IPv4 SFTP server and enter SFTP client view.
Syntax
In non-FIPS mode:
sftp server [ port-number ] [ vpn-instance vpn-instance-name ] [ identity-key { dsa | rsa } |
prefer-compress { zlib | zlib-openssh } | prefer-ctos-cipher { 3des | aes128 | des } | prefer-ctos-hmac
