I don't prevent it on the front end, but I do check it periodically with this:
SELECT SUBSTR(a.JOB_NAME, LOCATE_IN_STRING(a.JOB_NAME, '/', -1) + 1) AS SessionA,
a.Remote_address,
a.local_address,
a.Authorization_name,
SUBSTR(b.JOB_NAME, LOCATE_IN_STRING(b.JOB_NAME, '/', -1) + 1) AS SessionB,
b.Remote_address,
b.local_address,
b.Authorization_name
FROM qsys2.netstat_job_info a,
qsys2.netstat_job_info b
WHERE a.local_port IN (
23,
992
)
AND a.authorization_name IS NOT NULL
AND a.authorization_name <> 'QTCP'
AND a.job_type = 'INTERACTIVE'
AND b.local_port IN (
23,
992
)
AND b.authorization_name IS NOT NULL
AND b.authorization_name <> 'QTCP'
AND b.job_type = 'INTERACTIVE'
AND a.remote_address <> b.remote_address
AND a.authorization_name = b.authorization_name;

If you're trying to make sure that someone doesn't use telnet from two different IP addresses and you figure it out, I'd love to know that.

Subject: RE: QIBM_QTG_DEVINIT exit program - blank user name
Because they did not specify auto signon? From the manual:
<snip>
The user profile that the system uses for the sign-on procedure
if you have enabled the auto-signon flag.

Subject: QIBM_QTG_DEVINIT exit program - blank user name
CAUTION: This email originated from outside of the organization. Do not click links or open attachments unless you recognize the sender and know the content is safe.
I activated an exit program to trap telnet init info. The problem i am
having is sometimes the user name is blank.
Table to store info retrieved
E2USER E2DEV E2IP
TESTC | SNICKA0 | 10.0.0.26
MARIAD | MARIADB0 | 10.0.3.34
PGMB0 | 10.0.6.3
The blank user name entry (device PGMB0), is from a client access
session on a remote pc that is connected with a VPN tunnel.
Any ideas why user name would be blank?
