Abstract

The workstation redirector makes an implicit connection from the workstation to the server whenever a UNC-style access occurs, such as 'DIR \\Servername\Netname' or 'TYPE \\Servername\Netname\file.txt'. Currently on OS/2 Lan Server 1.3 and OS/2* Lan Server 2.0, entering a 'NET USE' command can only display all the explicit and deviceless connections, but not the implicit connections. Hence, a user does not know nor keep track of the exact number of total connections to a particular server share. This information is critical to a user because some shares may have a restriction on the number of users accessible concurrently to the resource and would result in an error if the limit is exceeded. To solve this problem, OS/2 Lan Server 3.

Enables IBM OS/2 LAN Server 3.0 'Net Use' Command To List All Implicit Connections

      The workstation redirector makes an implicit connection from
the workstation to the server whenever a UNC-style access occurs,
such as 'DIR \\Servername\Netname' or 'TYPE
\\Servername\Netname\file.txt'.  Currently on OS/2 Lan Server 1.3 and
OS/2* Lan Server 2.0, entering a 'NET USE' command can only display
all the explicit and deviceless connections, but not the implicit
connections.  Hence, a user does not know nor keep track of the exact
number of total connections to a particular server share.  This
information is critical to a user because some shares may have a
restriction on the number of users accessible concurrently to the
resource and would result in an error if the limit is exceeded.  To
solve this problem, OS/2 Lan Server 3.0 'NET USE' command would list
all the implicit connections along with explicit and deviceless
connections.

      To list the implicit connections with a 'NET USE' command in
OS/2 Lan Server 3.0, each implicit connection must first be
identified from the enumerated list of all current connections on the
workstation by checking that both the ui1_usecount and ui1_refcount
members of use_info_1 structure of each use entry is 0.  Once a
connection is identified as implicit, it will be displayed (by NET
USE command) with its remote name and with the status as 'Dormant',
as shown below:
 Status          Local name      Remote name
