Telnet tool shutdown -- MIDRANGE-L

Booth,
The telnet tool you are talking about is the Microsoft telnet client.  This
client does not negotiate a terminal type when the remote host is an
AS/400.  This generates a VT100 ascii signon for an AS/400.

The named devices support is part of the tn5250e RFC.  This is fully
supported on an AS/400 in a 5250 session.

ISPs usually do not run a telnet server.  There could be some security
holes since a Windows NT has a default profile of Guest that anyone could
use to signon a telnet session, signon as guest and destroy data in Windows
NT.

The AS/400 has user profiles with plenty of object level security to
prevent someone from
getting to data only if they are authorized.

Worse than a 3 hour delay is when I receive two or three replies to a
message that I don't get for 2 or 3 hours - the replies arrive well before
the original.

|Hi Booth,
|
|Blind eye and deaf ears. Haven't heard a thing. What do you mean "shutting
|down the telnet tool"? ISP's refusing port 23 connections? That would be a
|serious problem since I use TN5250 to connect to my customers.
|What have you
|heard? Or read? Or experienced?
|

|P.S. I notice about a 3 hour time lag between when messages are posted and
|when I receive them. I already mentioned it to David, but I was
|wondering if
|anyone else has shorter lags.

| Even worse than all this energy and money being spent on some mystical
| naming schema is their apparently blind eye to what is happening with
| Microsoft.  Has anyone else had complaints or seen evidence of Microsoft
| shutting down the telnet tool?  I've seen at least two mentions of
| Internet Service Providers disabling telnet because it is too big a
| security exposure.  Further questions have been answered with "everybody
| uses Windows so no one needs telnet anymore."
|
| I've wondered why the Windows telnet program has always been so ugly and
| now I guess the answer is out. But, where will that leave TN5250?
