-i interface-type interface-number: Specifies an output interface by its type and number. This option is
only used when the server uses a link-local address. The specified output interface on the client must have
a link-local address.
get: Downloads the file.
put: Uploads the file.
source-file-name: Specifies the directory of the source file.
destination-file-name: Specifies the directory of the target file. If this argument is not specified, the
directory names of the source and target files are same.
identity-key: Specifies a public key algorithm for the client, either dsa or rsa. The default is dsa. If the
server uses publickey authentication, this keyword must be specified.
• dsa: Specifies the public key algorithm dsa.
• rsa: Specifies the public key algorithm rsa.
prefer-compress: Specifies the preferred compression algorithm between the server and the client. By
default, compression is not supported.
zlib: Specifies the compression algorithm zlib.
prefer-ctos-cipher: Specifies the preferred client-to-server encryption algorithm. The default is aes128.
Algorithms des, 3des, aes128, and aes256 are arranged in ascending order in the aspects of security
strength and calculation time.
• 3des: Specifies the encryption algorithm 3des-cbc.
• aes128: Specifies the encryption algorithm aes128-cbc.
• aes256: Specifies the encryption algorithm aes256-cbc.
• des: Specifies the encryption algorithm des-cbc.
prefer-ctos-hmac: Specifies the preferred client-to-server HMAC algorithm. The default is sha1.
Algorithm sha1 features stronger security but costs more time in calculation than md5.
• md5: Specifies the HMAC algorithm hmac-md5.
•
md5-9
6: Specifies the HMAC algorithm hmac-md5-96.
• sha1: Specifies the HMAC algorithm hmac-sha1.
• 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 dh-group14 in FIPS mode. Algorithm dh-group14 features stronger security but costs
more time in calculation than dh-group1.
• dh-group-exchange: Specifies the key exchange algorithm diffie-hellman-group-exchange-sha1.
• 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 sever, which is used to authenticate the server.
The keyname argument is a case-insensitive string of 1 to 64 characters.
source: Specifies a source IPv6 address or source interface for IPv6 SCP packets. By default, the IPv6 SCP
packets automatically select an IPv6 address as their source address in compliance with RFC 3484. For
successful SCP connections, use one of the following methods:
