[BALU] Determining log-on rights/permissions on SuSE 11.3

I'm sorry, if that's what you picked up, I must have misphrased my original request.
I'm not looking for information on the PostgreSQL setup; I'm trying to figure out how to ensure that the users can connect to the actual Server Box itself - somewhat of a requirement for being able to use anything on it.  Given that they're coming from what I believe (if I understand the terms correctly*) is a different subnet, how do I make sure that users (or, in this case, client-side programs) on that subnet can access the box on the 'main' subnet?

*And if I'm not correct on this, would someone please be kind and point me in the direction of the proper terminology?

  Andrew,


  I understand your question to be:
  How do I change the network address that users are allowed to connect to the PostgreSQL database from?


  The PostgreSQL database uses the pg_hba.conf file to authorize network (and local) connections to the database.  You have 5 types of authentication methods to select, the database, the user and the host address (or network).


  After modifying the pg_hba.conf file, you can issue a "pg_ctl reload" (as documented in the pg_hba.conf file) as a database superuser.

    I've recently been informed that the official location for one of the servers we maintain will be picking up a branch location.  (Offices have an internal pattern of '###.###.N.###' for their IP combos; the new branch has a different value of N from the main office.)  I've been requested to verify that the systems from the branch site will be able to log into the main office's server.  I know how to check and verify the login IP values for the mysql database, and I'm fairly confident I can figure out what I'll need to permit the postgres system to accept the new branches, but where do I need to look and reset in order to ensure that the systems can actually log into the server itself?
