Throttling provides the capability to manage the rate of file transfers. It allows you to set the limits on bandwidth usage to prevent the utilization of the entire network capacity for file transfers. Throttling allows you to control:
Restrict particular operations for files that match a specified pattern. Set the following server restrictions:
Ciphers are algorithms that encrypt or decrypt data. Specify the SSL ciphers that IBM webMethods Managed File Transfer applies to all SSL listeners associated with a server instance.
File-based encryption and decryption enables you to encrypt files before you store them on your drive. Encrypted files are decrypted when they are transferred back using the same key that was used to encrypt them. IBM webMethods Managed File Transfer encrypts and decrypts files instream rather than after the file is fully transferred.
When encryption and decryption keys are configured at multiple levels (user, server, and folder), IBM webMethods Managed File Transfer enforces the following order of preference:
Users
Folders
Servers
For example, if user A accesses port 10 and uploads a file in VFS TestFolder123, then IBM webMethods Managed File Transfer checks if the encryption or decryption key is available for user A. If no key is available at the virtual folder level, then IBM webMethods Managed File Transfer checks for the user settings for the key. If no key is present at the user settings level, then IBM webMethods Managed File Transfer checks the server level settings for the key. If no key is present at the server level settings, then files are not encrypted or decrypted during upload or download.
Hammering is a term used to describe a type of network activity in which a client repeatedly attempts to access a server or perform certain actions against the server’s configuration, often in a way that exceeds normal or expected usage patterns.
Use the hammering configurations to do the following:
After a client triggers the hammering setting by performing actions that match the pre-set configurations, the IP address is not immediately banned. Instead, a background process checks for hammering on the server from any specific IP address every few seconds. If the process detects hammering from a particular IP address, that address is banned for the duration that is configured.
When IBM webMethods Managed File Transfer or an associated cloud pod goes through an unexpected restart or a planned maintenance, the in-progress scheduled actions or post-processing actions can sometimes get terminated without a graceful completion, resulting in the execution status to persist in an In-progress state indefinitely. The administrator does not get notified of this failure, which can eventually cause business loss if left uncorrected.
Email notification for in-progress actions functionality facilitates your cloud administrator to receive email notifications whenever an in-progress action is interrupted.
Go to General settings > Miscellaneous settings to access this functionality.

Select the IBM webMethods Managed File Transfer instance from the Instance list and specify the following settings:
Field | Description |
---|---|
Maximum simultaneous user connections | Type the maximum number of client connections allowed for the server at any given time. |
Maximum outgoing speed (Kb/sec) | Type the maximum allowable speed in kilobytes per second for outbound transfers across all listeners. |
Maximum incoming speed (Kb/sec) | Type the maximum allowable speed in kilobytes per second for inbound transfers across all listeners. |
Active time window | Select the days of a week you want the server to be available to the user. |
File name filters | Configure the file name filters to allow or deny commands (upload, download, list, rename) for files that match a specified pattern. For example, restrict a user from uploading files that end with “.exe”.
|
Patterns | Click to add one or more patterns to restrict a particular operation for certain files, and specify the following details:
Note
Wildcard characters and regular expressions are not supported. That is, you cannot use characters such as * or % to represent any sequence of characters.
|
Block paths matching these patterns | Click to restrict access to specific folders and subfolders in the file system, and specify the following:
Tip
Precede a pattern with a tilde character (~) to apply the pattern for all occurrences. For example, to deny user access to the folder /system/bin type:
~/system/bin/* |
Field | Description |
---|---|
Ban IP address after unsuccessful attempts | Ban a user’s IP address after a certain number of connection, password, or command execution attempts. Select the values for Connection, Password, and Command rows to configure the following settings:
|
Ban the IP addresses of users after the first incorrect password | Ban the IP address associated with a specific user after the user’s first incorrect password attempt. Click and type the user name for whom you want to ban the IP address. |
Ban specified IP addresses | Do one of the following after adding the IP addresses associated with users after the first incorrect password attempt:
|
Cache invalid usernames for (sec) | Type the number of seconds to hold the name of invalid users in the cache temporarily. The temporary caching of invalid usernames is useful for blocking robots that make repeated attempts to discover valid user credentials. When a robot scans IBM webMethods Managed File Transfer during the user validation process, this option blocks subsequent login attempts made using an invalid user name for the specified number of seconds. If the username is valid, IBM webMethods Managed File Transfer ignores this setting. |
Slow down hack attempt scans | Select this option to incrementally slow down responses to a client that appears to be a robot scanning for writable directories on your server by establishing an FTP connection. This setting doubles the response time of the server for each subsequent response to the client, thereby rendering such robots less effective. Selecting this option does not result in any extra load on the CPU. |
Send email notification when IP is banned | Select this option to receive notifications on e-mail when an IP address is banned. Type the e-mail address in the following field. |
IP restrictions | Click to add one or more IP addresses for which IBM webMethods Managed File Transfer can accept or deny connection requests and specify the following details:

Azure AD users appear automatically in all user and group related sections. Azure AD users cannot be updated or created from IBM webMethods Managed File Transfer, they can only be viewed.
Azure AD implementation provides access to partner users only, and these users do not have access to IBM webMethods Managed File Transfer user interface. Partner user permissions provided in the UI permissions section are therefore not applicable to Azure AD users.
As an Azure AD client, IBM webMethods Managed File Transfer performs the following operations:
Provide a valid set of permissions in your Azure console to perform these operations. The corresponding operation fails if the required permissions are not granted to the client.
Example:
Application level type permission
Directory.Read.All
: List all users, groups and member associations.
Delegated level type permission
User.Read
: Login and read the user profile.
