Description
The following actions are executed using command "sc vncpwd":
● sc vncpwd set to assign a password.
● sc vncpwd reset to delete a password.
Syntax:
Alternative names:
Authorization level:
Using command "sc vncpwd set", on the server (NCU) a password is set up for the VNC
connection via the company network or the factory network. As soon as a password has been
assigned, a connection can only be established from an VNC client (TCU, Ultr@VNC, etc.) by
specifying the correct password.
Command sc vncpwd set always asks for a password to be entered.
Or, for example: sc vncpwd set systemnetwork secreT7+
Command sc vncpwd reset deletes the password for the specified network. A connection
in the network is therefore possible without authentication.
Note
Password in the network
In the network (factory network or company network), in order to access any server (NCU) in
the network from a TCU (client) via a VNC connection, all servers should use the same
password.
