Communications Access Methods for SAS/CONNECT and SAS/SHARE Software

SHARE

System Administrator or User

To use the DECnet access method with a Windows host for SAS/CONNECT and SAS/SHARE, perform these tasks:

Verify that you have met all your site and software requirements.
Verify that you know how to set options in SAS software.
Set the SAS/CONNECT and SAS/SHARE options that you want.

System and Software Requirements for SAS/CONNECT and SAS/SHARE

Ensure that the following conditions have been met:

The DECnet software has been installed at your site.
SAS has been installed on both the local and remote hosts.
For Version 3.51 of Windows NT, Digital Equipment Corporation Pathworks for Windows NT Version 5.1 or a subsequent version has been installed at your site.
For Version 4.0 of Windows NT, Digital Equipment Corporation Pathworks 32 has been installed at your site.
For Windows 95, the Microsoft Winsock Version 2.0 and Digital Equipment Corporation Pathworks 32 have been installed at your site.
For Windows 32s, Digital Equipment Corporation Pathworks for DOS and Windows Version 5.1 or subsequent version have been installed at your site.

Setting SAS Options and Variables

You may set specific options in SAS to establish the connections that you want with SAS/CONNECT and SAS/SHARE when using the DECnet communications access method.

You may specify an option in any of several forms, as follows:

in an OPTIONS statement in a SAS session or in an AUTOEXEC file:
OPTIONS SET=variable-name value
Example:
```
options set=sassecur _prompt_;
```
in a SAS configuration file or at a SAS invocation:
-SET variable-name value
Example:
```
-set sassecur _prompt_
```
as a SAS macro variable:
%LET variable=value;
Example:
```
%let sassecur=_prompt_;
```
as a DOS operating system environment variable:
SET variable-name=value
Example:
```
set sassecur=_prompt_
```

Values for these options can contain up to eight characters, consisting of alphanumeric characters, the percent sign (%), the dollar sign ($), the pound sign (#), the at sign (@), and the underscore (_).

If you set multiple forms of the same option, the order of precedence follows:

SAS macro variable

OPTIONS statement

AUTOEXEC file

SAS invocation

SAS configuration file

DOS environment variable.

SAS/SHARE SASSECUR Option

CAUTION:: Windows NT only SAS/SHARE server security is supported on the Windows NT platform only.

You must set the SASSECUR option in order to pass a remote host user name and password to a SAS/SHARE server for verification. After the user name and password have been verified, the connection to the SAS/SHARE server can proceed. Values for SASSECUR are

SASSECUR _NONE_ | _PROMPT_ | username.password | _SECURE_

_NONE_

must be set at the SAS/SHARE client. This is the default.

Setting _NONE_ does not establish secure sessions for connecting SAS/SHARE clients.

_PROMPT_

must be set at the SAS/SHARE client.

_PROMPT_ specifies that SAS prompt the user for user name and password information. When prompted for a password, the input field is not displayed. Choosing to prompt for user name and password provides more security than assigning the user name and the password to the system option.

userid.password

must be set at the SAS/SHARE client.

This value specifies both the user name and the password. Assigning the user name and password directly to the SASSECUR option at the SAS/SHARE client may inadvertently publicize this information and compromise the security of the SAS/SHARE server. Assigning the value to the option in a file allows anyone to read it.

_SECURE_

must be set at the SAS/SHARE server on a Windows NT host only.

The _SECURE_ value for the SASSECUR option requires a SAS/SHARE client to supply a valid user name and password to the remote host or the remote host on which the server is running in order to allow client access to the server.

Specify the SASSECUR option before you create a server.

Examples:

%let SASSECUR=_NONE_;
%let SASSECUR=_PROMPT_;
%let SASSECUR=bass.timego;
%let SASSECUR=_SECURE_;

See Setting SAS Options and Variables for examples of the forms that you can use to specify the SASSECUR option.
