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

UNIX: TCP/IP Access Method

SAS/CONNECT

Local Host

The following example illustrates the statements that you specify in a UNIX local host SAS session to connect to a remote host with the TCP/IP access method:

filename rlink '!sasroot/misc/connect/tcptso.scr';
options comamid=tcp remote=rmtnode;
signon;

The first line identifies the script file that you use to sign on to an OS/390 remote host. The script file contains a prompt for a userid and a password that are valid on the remote host. The TCP/IP communications access method is declared with a connection to the remote host RMTNODE. The SIGNON statement performs the sign-on process. The USER= option in the SIGNON statement specifies that a local host be prompted for a username and a password that are valid on the remote host.

Remote Host

You may set the following options in the remote host configuration file to restrict port access:

-tcpportfirst 5020
-tcpportlast 5050

These statements restrict access to ports 5020 through 5050.

A typical example of how to invoke the UNIX spawner program at the UNIX remote host follows:

!sasroot/utilities/bin/sastcpd -service unxspawn

The UNIX spawner program UNXSPAWN is invoked.

SAS/SHARE

Client

The following example illustrates the statements that you specify in a UNIX client SAS session to access a server with the TCP/IP access method:

options comamid=tcp;
libname sasdata 'edc/prog2/sasdata' server=rmtnode.share1 user=_prompt_;

The TCP/IP access method is declared. The LIBNAME statement specifies the data library that is accessed through the host RMTNODE.SHARE1. The USER= option in the LIBNAME statement specifies that a client be prompted for a username and a password that are valid on the server.

Server

The following example illustrates the statements that you specify in the server configuration file on a UNIX host:

-set tcpsec _secure_
-set authencr required

The _SECURE_ value for the TCPSEC variable requires clients to supply a userid and a password that are valid on the server. The AUTHENCR REQUIRED variable setting accepts only encrypted userids and passwords from clients.

The following example illustrates the statements that you specify in a SAS session on the UNIX host at which you start a server:

options comamid=tcp;
proc server id=share1;
run;

The TCP/IP access method is declared and the server SHARE1 is started on the UNIX host.
