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.
