User Passwords
Two separate user accounts (user name and password) can be set up for
SNMP and HTTP access.
Account types:
‘
Read Only’
can only read values and configuration settings
‘
Read Only + Outputs’
can read values and set outputs, cannot change
configuration settings (not even sensor names)
‘
Read & Write
’ can perform any changes
The “Read Only” account only has read access to values, cannot perform any configuration
changes. The “Read&Write” account can change configuration settings.
After setting a login name and password, you will be asked to enter the login details
every time you attempt to open the WWW interface.
Passwords also apply to access to the values.xml and setup.xml files
– see the table.
In case of “Read Only” HTTP access, you will no longer be able to change
configuration settings in WEB setup.
IP Access Filter
Allowsyou to define a range of trusted IP addresses that are allowed to access the Poseidon
over HTTP and SNMP. Each protocol has its own range.
Always only the IP addresses range is set, using the default IP address and the range
around the entered value (mask), following the pattern where AND is bit multiplication.
Access is granted if the above condition is true.
