SFTP, SCP, or SSH MFT Connection Properties

Create an SSH (SFTP, SCP, or SSH) MFT Connection to define communications using the SFTP, SCP, or SSH protocol for an MFT Remote endpoint. Informatica Managed File Transfer can connect to SSH Servers to perform SFTP (SSH File Transfer Protocol) file transfers, SCP (Secure Copy) file transfers and to run SSH remote commands. When defining an SSH MFT Connection, you must indicate the connection properties such as the host name or IP address and user. You can specify a password, SSH private key or both for authentication.

The following table describes the properties in the

Basic

tab:

Property	Description
Name	Name of the MFT Connection.
Description	Provide a description for the MFT Connection.
Host	The host name or IP address of the server.
Port	The port number to use for connecting to the server. If left blank, the default port number is 21.
User	The user name to use for connecting to the server.
Password	The password to use for connecting to the server.

The following table describes the properties in the

Connection

tab:

Property	Description
Timeout	The number of seconds to wait when attempting to connect to the server. A timeout will occur if the connection cannot be established in the specified amount of time. If left blank, the default timeout is 120 seconds.
Connection Retry Attempts	The number of times to retry the connection if it cannot be established. This setting is used for both the initial connection and any reconnect attempts due to lost connections. If left blank, then no retries will be attempted.
Connection Retry Interval	The number of seconds to wait between each connection retry attempt. For instance, if you want Managed File Transfer to retry the connection up to 10 times with a 5 second delay between retries, then specify 10 for the Connection Retry Attempts and 5 for the Connection Retry Interval.
Initial Remote Directory	The initial directory to start in after connecting to the server. If left blank, then the initial directory will be the home directory assigned to the user on the server.
Throttle Bandwidth	Limit the inbound and outbound bandwidth used for file transfers.

The following table describes the properties in the

Proxy

tab:

Property	Description
Proxy Type	Managed File Transfer supports SOCKS (version 4 and 5), HTTP tunneling through an HTTP proxy and Managed File Transfer Gateway. HTTP tunneling requires that the HTTP proxy supports the CONNECT HTTP method. Not all HTTP proxy servers may support the CONNECT method and some might only allow HTTPS traffic. When using an HTTP proxy that requires authentication, Basic and Digest authentication schemes are supported. Check with the network administrator for the correct proxy type.
Host	The host name or IP address of the proxy server. If the Proxy Type or Host fields are blank, a direct connection to the target host is implied.
Alternate Host	The host name or IP address of an alternate proxy server. The alternate proxy server is used when the primary proxy server is unavailable.
Port	The port number to use for connecting to the proxy server. If left blank, the default port for an HTTP connection is 80 and SOCKS is 1080.
User	The user name to use for connecting to the proxy server.
Password	The password to use for connecting to the proxy server.

The following table describes the properties in the

SSH Keys

tab:

Property	Description
Host Key	The fingerprint of the server's public key, which will be used to authenticate the server. If a fingerprint is not specified, then the server will be treated as trusted.
Private Key Alias	The private key used to authenticate the server, which is located in the SSH Key Manager.
Private Key File Password	The password to use for accessing the Private Key File. After entering the password, you can optionally click the Encrypt button, which will encrypt the password when it is stored in Managed File Transfer's database. A private key password is only required if using SSH private key authentication or both password and SSH private key authentication.

On the Algorithms tab, specify the authentication options and algorithms to use for this SFTP, SCP, or SSH connection. The following table describes the properties in the

Algorithms

tab:

Property	Description
Authentication	Specify the authentication option to use for this connection. The following options are available: gssapi-with-mic publickey password keyboard-interactive
Cipher	Specify the cipher option to use for this connection. The following options are available: aes256-cbc aes192-cbc aes128-cbc 3des-cbc blowfish-cbc twofish256-cbc twofish-cbc twofish192-cbc twofish128-cbc serpent256-cbc serpent192-cbc serpent128-cbc arcfour idea-cbc cast128-cbc des-cbc arcfour128 arcfour256 aes128-ctr aes192-ctr aes256-ctr 3des-ctr blowfish-ctr twofish128-ctr twofish192-ctr twofish256-ctr serpent128-ctr serpent192-ctr serpent256-ctr idea-ctr cast128-ctr
Mac	Specify the mac connection option to use for this connection. The following options are available: hmac-md5 hmac-sha1 hmac-sha2-256 hmac-sha1-96 hmac-md5-96
Compression	Specify the mac connection option to use for this connection. The following options are available: none zlib zlib@openssh.com

The options on the Algorithms tab allow customization of the supported algorithms for each SSH server resource. The entries in the left column are the available algorithms and the entries in the right column are the selected algorithms. By selecting one or more algorithms, only those will be used during the communication. If no algorithms are selected for a section, the defaults for that section will be used.

During the handshake process, the selected options are negotiated with the server, starting with the entry at the top of the list. The first cipher and mac and compression algorithms to match an algorithm supported by the server will be used for the connection. If your company prefers certain algorithms over others, use the arrow buttons to move that cipher to the Selected column and to set the order with the most preferred algorithm at the top. Press the CTRL key while clicking to select multiple entries.
