Does the postgres Database contains/maintain the details of remote access like ip addresses? - postgresql-9.5

We have the pg_hba.conf entries for the remote access in PostgreSQL. Does PostgreSQL stores those data in the database itself?

View Dropped IP Addresses in Azure SQL Whitelist

Is there a way to query Azure SQL server logs to see when an IP address was dropped from a whitelist? Thanks!
First enable Auditing on the Azure SQL Database:
Next Create Log Analytics workspace and try to query:
We could not get the IP which failed connecting to the Azure SQL database as of the date.
However,we can get the sum/count of Failed/Successful Connections:

Postgres database?

I have set up a database using PostgresSQL, the host is set as local host. I want to know how to connect to that database using other software e.g. tableau and to let other people access and manipulate the database, to do this I need the host name/address along with the port number and password, how do I find out the host name/address to connect with? or how do I when creating the server save the host name as something that I can connect to which isn't local host?

How download a backup sql database from server with permission

For example I have a backup SQL Server database on IP : 192.168.1.2 and I want to get backup this database from other server.
SQL Server has permission but I haven't accessed to IP address.
How can I solve this?
You don't need to have access to ip address to initiate backup(assuming you have permissions to backup) unless your ip address is in blocked list..
You can just initiate a backup request

Connecting access 2007 to sql server 2012

I've linked to a table in an sql server 2012 database using an odbc connection. This was straightforward and worked fine using my log in. When I attempted to open the linked table on another users computer I got an error saying I could not connect. I tried to set up the connection on their PC but couldn't see the database on the server. I logged on to sql server and gave that user a log on to the sql and access to the database using windows log in.
I still could not gain access to the database through access. Any idea what I'm doing wrong.
One Idea, you shall create all linked tables with a privileged user account of the SQL Server.
For example, if you enabled Trusted_Connection in the SQL Server, you can use the administrator's account of Windows, for example, johndoe2 for connection. If your SQL Server is installed on the LAN host masterserver, a linked table can be created as this:
ODBC;DRIVER=SQL Server;SERVER=masterserver\SQLEXPRESS;Database=[MyDatabase];UID=johndoe2;Trusted_Connection=Yes;TABLE=dbo.[MyTable]
In our case we can access MyTable throuhg Access 2007 on the host biomas that is on the same LAN as the masterserver.

How to allow access for a sql server user?

I am a developer-having-to-play-admin and wish to connect to a remote sql server from my development machine using a sql server user ("op_web").
When I try to connect from vs2008 Server Explorer, I can connect to the server, but no databases are listed. If I connect using the server admin user, all databases are listed as expected.
The server is a relatively fresh install made by me.
I have
allowed for remote connections in sql server.
created the login op_web at server level
created a user at database level and assigned to login with same name
assigned roles to the user to allow for reading and writing - I have assigned no schemas and default schema for the user is dbo.
If I log on (locally at server) using sqlserver management studio/sqlserver authentication and the created login, I can display and alter table data as I would expect.
Remote access gives me no choice of databases.
Any pointers to what I might have missed?
You have to give your users rights on the database.
