Administrator password
Administrator password for downgrade to releases before 4.2.x
Attention
Starting with SW release 4.2 we set default to not saving passwords using password
hashes instead. Storing passwords for users can be enabled, but is not recommended
for new applications.
Older SW releases require the passwords to be stored encrypted on the device. As
we don’t have them any more in release version 4.2 and later you will have to provide
the administrator password if you want to downgrade to a release 4.1.x and lower. The
same passphrase will be used for bootloader login as well.
All users which have no password stored on the device will not be able to login after
downgrade until new passwords have been applied.
An Uniform Resource Locator (URL) can have the following format:
http://<username>:<password>@<host>:<port>/<path>
https://<username>:<password>@<host>:<port>/<path>
ftp://<username>:<password>@<host>:<port>/<path>
sftp://<username>:<password>@<host>:<port>/<path>
tftp://<host>/<path>
file:///<path>
When issuing a software update, the current configuration (including files like keys/certificates) will be
backuped. Any other modifications to the filesystem will be erased.
The configuration is generally backward-compatible. We also apply forward compatibility when down-
grading to a previous software within the same release line, which is accomplished by sorting out
unknown configuration directives which actually may lead to loss of settings and features. Therefore,
it’s always a good idea to keep a copy of the working configuration.
