Re: [ADMIN] Acess Control !

It is read from up to down until specific criteria is true. It stops there and doesn't read thru rest of the lines.

Good morning pinker,

Thank you for approch, but i maked this teste:

1.  Reject xpto  connection from all adress and  after acept  xpto connection from this adress - result  = work good (lock connection for xtpo come from other adress and acept from this adress)
   

# TYPE  DATABASE        USER         ADDRESS           METHOD

host       xpto                   system       10.72.18.0/24         reject

   host        xpto                   system       0.0.0.0/0                 reject 
   host       xpto                   system       10.75.15.60/32       md5

              host       all                       all             0.0.0.0/0               md5  

 

 

1.  acept xpto  connection from especific adress and  after reject from all connection - result = (acept all connection, that  come from all adress )
   

# TYPE  DATABASE        USER         ADDRESS           METHOD

host       xpto                   system       10.75.15.60/32       md5

               host       all                       all             0.0.0.0/0                md5 

               host       xpto                   system       10.72.18.0/24         reject
               host        xpto                   system       0.0.0.0/0                 reject 

So, maybe the read come from up to down? or have other explanation? i don't know, i use postgres 9.4.

be careful with order change. This proposed by Scott was correct; yours will
reject all the connections made by user system to xpto. Documentation says:
