GBASE - 8 a data support for the user's white list access control (can control the IP access only), but can't do the blacklist control (i.e., don't allow those IP access),
Generally there are two commonly used methods:
A, create for users with IP directly,
User @ '192.168.0.0//segment
The user @ '192.168.10.6,//IP address
Eg: the create user [email protected];
PS: through the IP or wildcard this @ belt, landed don't need to input the corresponding IP, namely login or gccli utest - p...

Second, through the list of hosts landing IP control,
The create/alter user host_option: {hosts' host_list '};
Eg: the alter user test hosts' 10.1.1.68 10.1.1.40 ';
Multiple IP separated by Spaces, and at the same time support wildcards way,
PS: administrator gbase account now can't change way, grammar is not an error, but actually cannot limit gbase users,
