Introduction to Advanced Server for UNIX Connection management

Product Manual U7613-J-Z815-6-76

2.4 Connection management

The following sections contain descriptions of a network connection between the server and

the client. The terms “session” and “network connection” are explained and the security

concept of Advanced Server for UNIX is introduced.

2.4.1 Sessions

A session is set up between a client and a server the first time when a connection from the

client to a server resource was successful. (N.B. Windows NT clients sometimes have two

sessions to the same server). Every client can have several sessions with several servers.

● Sessions are also set up between the servers in a domain; likewise, local

sessions exist on the server. The command net session shows all current

sessions.

● The MAXCLIENTS parameter restricts the number of sessions that can exist

simultaneously. See also section “Parameters” in chapter “Lanman.ini File” in

this manual.

2.4.2 Connection to a resource

If the client user successfully connects to a resource first time from a server, a session is

automatically set up for this server (see above). However, if there is already a session with

this server then a new connection is set up to the required resource of this server using the

existing session.

A connection is explicitly cleared down from a client using the command net use and the

option /delete. On the other hand, if the session with a server is shut down then all connec-

tions to the shared resources of this server are closed.
