Problem Note 70114: The message "NOTE: Telnet Deprecated; connection not allowed" occurs when using SAS/CONNECT® Telnet connections (SIGNONs)
 |  |  |  |  |
Beginning with SAS® 9.4M8 (TS1M8), SAS® Viya® 3.5 with the associated hot fix, SAS/CONNECT Telnet SIGNON connections to remote Telnet daemons/task
(connecting to remote TCP port 23) no longer work.
If you attempt to sign on to a Telnet daemon, the following error occurs in the SAS log:
Alternatively, you must execute a SAS/CONNECT spawner on the remote host. The SAS/CONNECT spawner can be configured as part of a SAS metadata environment or as a SAS® Foundation component (not part of a SAS metadata environment). For details about how to configure a SAS Foundation SAS/CONNECT spawner daemon, refer to SAS/CONNECT User's Guide: Spawner Connections on UNIX and Configuration Guide for SAS 9.4 for z/OS.
The SAS/CONNECT client SIGNON code to a SAS/CONNECT spawner does not need the FILENAME RLINK assignment. However, you need to include the TCP port that the SAS/CONNECT spawner uses for the -SERVICE parameter and also need to provide credentials in the SIGNON statement.
Here is an example of changes that you need to make to execute a SIGNON statement to a SAS/CONNECT spawner:
FILENAME RLINK 'C:\Program Files\SASHome\SASFoundation\9.4\connect\saslink\xxxxxx.scr';
%let RMT=a.b.c.sas.com;
OPTIONS REMOTE=RMT;
SIGNON;
/* on the remote host, edit the SIGNON code with the FQDN of the */
/* remote hosts and the port number used for the -SERVICE Spawner parm */
/* example SIGNON to SAS/CONNECT Spawner port using 7551 */
%let rmt=a.b.c.sas.com 7551;
SIGNON rmt USER=<rmt userid> PASS=<rmt pswd>;
SIGNON rmt USER=_prompt_ ;
Note:
- This hot fix removes the ability to specify the -CLEARTEXT parameter with the SAS/CONNECT spawner.
- This hot fix might be applied automatically with a new SAS 9.4M8 install and will disable a TELNET SIGNON.
