This is the list of known issues for the current release of SFTPPlus.
[#1054] No support for non-ASCII characters in the server’s installation path.
In order to ensure correct operation of SFTPPlus, please avoid using special Unicode characters in the installation folder path.
[#1245] Events logged in Windows Event Logger are listed without a specific Windows description.
Events logged in Windows Event Logger are listed without a human friendly Windows description. Nevertheless, the data exported as XML is detailed and complete.
Copying a Local Manager URL from within an authenticated session and pasting it in an unauthenticated session will prompt for the login page. After a successful authentication, the new session will redirect to the start page, not to the initial requested page.
Collaborative configuration from multiple separate Local Manager sessions is not supported. The Local Manager allows opening multiple administration sessions, but assumes that only one session will change the configuration. Changes in one session will not be automatically reflected in the other session. You will need to refresh the page in order to see the changes.
Internationalized Domain Names are not supported. The server itself and all systems with which it interacts should use ASCII domain names.
[#1400] When the server fails to start, it will only emit the general log event 20002 to signal that the server is stopping, without sending dedicated 20078 events for each service that was initially started. Service stop events are still emitted when a service is stopped at running time from the Local Manager or when the server is stopped in a normal way.
[#1470] The Local Manager will not warn when adding multiple services, accounts, and groups with the same name. No error is generated because internally the server uses UUIDs for addressing these items.
[#1588] On service start/stop the audit entries for these actions have no field mentioning the administrator requesting the action.
[#1787] HTTP Post Request log handlers accept HTTPS URLs, but do not validate the SSL connection.
[#1935] In the HTTP/HTTPS file service, actions can only be triggered by explicitly clicking on buttons. Actions cannot be triggered using the ‘Enter’ keyboard key.
[#1946] On Windows systems, the installation will not generate an install log file when running in silent mode.
[#2057] SFTP symbolic links on Windows systems only work when using absolute paths.
When the server does not have write permissions to the configuration file and an administrator applies changes from the Local Manager, changes are applied, but they do not persist in the configuration. If you fix the permissions while the server is still running, there is no option to force a new save to the configuration file, other than making another change and applying it. Then, all previous changes will also be saved.
[#2134] On Linux, SFTPPlus cannot detect if the OpenSSL libraries provided by the operating system support TLS 1.0 or TLS 1.1. If you configure one of them on an OS with no support, the configured service will start and any connections will fail.
[#2383] On Windows systems, execute_before, execute_after_success, and execute_after_failure cannot be configured with a path containing space characters. Also, when any execute_* action is called for files containing non-ASCII characters, the passed file names are corrupted.
[#2547] When a password is used to import a private key which is not password-protected, the Local Manager will still inform you that the key is password-protected.
[#94] FTP session reinitialization command (REIN) is not yet implemented.
[#1160] FTP zlib compression command MODE Z is not yet implemented.
[#1161] FTP cyclic redundancy check using the CRC-32 algorithm XCRC is not yet implemented.
[#2357] FTP unique store command (STOU) is not yet implemented.
[#3294] When the file was successfully transferred but failed to be removed from the source location, the transfer is considered failed but source file is archived as a success.
[#3371] File dispatcher will not work for upload event for which the client is making the initial upload request under a provisional file name which is change once the file is successfully uploaded.
[#2135] SCP server implementation does not handle errors reported by the client side during file get / download operations.
[#3412] Files which are uploaded to the SFTPPlus using FTP or FTPS and for which the data channel is closed before the file was completely uploaded are reported as successfully uploaded. This is because when the file was successfully uploaded the data channel is closed in the same way.
[#2975] When using Syslog over TCP and the TCP connection is lost, SFTPPlus will try to reconnect, but all events emitted while trying to connect are discarded.
[#3478] When certificate revocation lists are configured, they will only work when the CA certificates are stored in a single file. Storing CA certificates in a single directory is not yet supported.
[#3461] On Windows, it is not possible to load certificates and CA files stored on paths containing non ASCII characters.
[#3494] When CRL distribution points (CDP) are configured only the first advertised HTTP CRL is used.
[#4382] CRL distribution points (CDP) are not supported yet for client side connections when the client does not identify itself with a certificate.
[#2672] Locations for FTP, FTPS and SFTP protocols will perform the connections using a fixed timeout of 10 seconds.
[#3583] Certificate distribution points are not yet supported for the client side connections like FTPS locations, when no local certificate is configured.
[#3602] The rotation time is not automatically changed when the system clock is changed (for example with daylight saving time). This leasds the roatation beying delayed when the clock is moved backwards.
[#3594] FTPS CCC command is only supported with Explicit FTPS for both client and server side. It is not yet supported for Implicit FTPS.
[#3599] FTPS CCC command is supported by the server-side only in active mode, while on the client-side only passive mode is supported. Please contact us if you need to communicate with a peer FTPS implementation which don’t support the above described modes.
[#3662] When using the components configuration option for an Event Handler the UUIDs are not yet verified to exist yet.
[#3663] The event handler target configuration option is not yet validated and accepts mixing ignored and allowed event ids. When configured using both methods, it will behave as the allow method.
[#2127] When SCP protocol is used, you can only download a single file as part of a SCP session.
[#4016] The FTP/FTPS client-side operation have no support for timezones. For a correct operation the client and server must use the same timezones and have the clock synchronized.
[#4315] When uploading files to SharePoint online via the WebDAV client protocol, large files transfers (above 200MB) might fail with SharePoint online aborting the transfer and closing the connection by returning a 404 error code without any reason.
[#4811] Fully qualified domain names (FQDN) or hostnames resolving only to an IPv6 address are not yet supported as the listening address for a file transfer service.
[#4869] When an HTTP file transfer service is closed for not being active, there is no explicit logout event.
[#5000] When a transfer is configured in any of the available batch modes, SFTPPlus will no longer monitor it once a file is added to the queue. If a file is added to the transfer batch queue and the file is removed from the source, SFTPPlus will still try to transfer it and the transfer will fail as the source file is no longer there.
[#5022] When a transfer has an Azure Files location as destination and is configured to rename existing files on destination, the transfer will fail as the rename operation is not yet implemented for Azure Files.
[#5071] For batch transfers, when using execute_on_destination_before, execute_on_destination_after_success and execute_on_destination_after_failure there is no way to define a command to be execute for each file from the batch. Only the last processed file is available as a variable.
[#5251] When the external-executable event handler is stopped, the external processes which were already started are not cancelled and will continue to execute.
The anonymous authentication method can only be used with accounts defined in the main configuration. It does not support accounts from a separate local file or accounts from other authentication methods.
SFTPPlus only detects daylight saving time changes while running. Timezone changes at runtime are not detected. If changing timezone on a system running SFTPPlus you need to restart SFTPPlus in order to apply the changes.
Updated file transfer debug configuration is applied on new connections. You will need to disconnect and reconnect to see the debug configuration applied for your session. Note that when using a web browser, the HTTP connections are persisted. You will need to close the tab or the browser to force a disconnection.
[#5531] Private password-protected ECDSA / Ed25519 keys are not supported yet.
[#5582] When the OS authentication method is configured with group-name or group-name-with-default the allowed source IP configuration and SSH public keys configuration are extracted from the default group.
[#5586] SCP file transfer protocol doesn’t support transfers for files with quotes in the path or filename. This issue doesn’t affect the SFTP protocol.
[#5598] When a transfer is configured to copy/move a file a destination using a temporary name and the content of the file is copied to destination but the rename operation fails, the transfer will fail, but the log will show the file as succeeded.
[#5606] The WebDAVS protocol is not supported by the client-shell command line tool.
[#5621] The LDAPS authentication only works with IPv4. Only LDAP authentication is supported for IPv6 address literals.
