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
in chapter
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.
