The Advanced tab contains configurations related to more specific use of the SFTP Advanced service.

|---|---|---|---|---|---|---|
| Advanced Settings | ||||||
| Max Async Request | Advance setting to tune the maximum asynchronous request a SFTP server can be handle, leave it empty, will use the default value(100) from library. | |||||
Port | The port number the SFTP service will use on the remote host. | |||||
Timeout (s) | The maximum time, in seconds, to wait for response from the server. 0 (zero) means to wait forever. | |||||
Accept New Host Keys | If selected, the agent overwrites the existing host key when the host is represented with a new key. The default behavior is to abort when the key mismatches.
| |||||
Enable Key Re-Exchange | Used to enable and disable automatic re-exchange of session keys during ongoing connections. This can be useful if you have long lived sessions since you may experience connection problems for some SFTP servers if one of the sides initiates a key re-exchange during the session. | |||||
| Additional Hosts Settings | ||||||
Additional Hosts | List of additional host names or IP-addresses that may be used to establish a connection. These hosts are tried, in sequence from top to bottom, if the agents fail to connect to the remote host set in their Connection tabs. Use the , , , and buttons to configure the host list. | |||||
Security Tab
The Security tab contains configurations related to the Advanced Security Options for SFTP. The Configuration available can be modified by selecting the Advanced Security Option check box. If the advanced security is not enabled, the Cipher Mode will default to aes128-ctr and the HMac Type will default to hmac-sha2-256. If advanced security is enabled but the combo box fields are left empty, the Cipher Mode will default to aes128-ctr and the HMac Type will default to hmac-sha2-256.

Due to an upgrade of the Maverick library for With Advanced Security Option disabled, Maverick will manage the connection between the SFTP agent and the server. Maverick will attempt to connect with the STRONG security level. Failing to do so, it will auto downgrade the security level to WEAK and attempt to connect, this behaviour will allow our agents to work well with backwards compatibility for servers with older instances of the Maverick library. Furthermore, having STRONG security level will result in a performance degradation. However, when a user manually enables the Advanced Security Option from the security tab, Maverick will instead assign the WEAK security level, which will not be as strict or resource intensive as the STRONG security level. For more information about security levels, you can refer to this page: https://www.jadaptive.com/managed-security-in-our-java-ssh-apis/ |
| Setting | Description |
|---|---|
| Cipher Mode | Algorithms for the Block Cipher Modes supported by the SFTP agent. This allows the agent to determine which algorithm for the block cipher to be used when communicating with the SFTP servers.
|
HMac Type | Methods of encryption for Key Exchange. This allows the agent to determine the method of encryption to be used when the keys are exchanged between the SFTP servers and the SFTP agent.
