I would appreciate if there is anybody who can advise me if the following FTP configuration is possible. I need range of read-only users that follow this pattern:
e.g., _012345678901234 that will use same password without creating all possible combinations. The use case is the following - we provisioning devices and they are using FTP to download new version of firmware. In the log I can see both username and password used to download files. The main goal is to have device serial number in the log.
I did not find a way to specify wildcard for username. Currently we have anonymous access only, but it's obviously not good enough.
