RE: Change telnet to another port?

[Roland Harris <Roland.Harris@xxxxxxxxxxxxxx>]

This will work if you follow the below process AND as per Jeffreys 
earlier memo,
ensure you have ptf SF53489 (for V4R3) or supercede (now SF60463) and 
follow the cover 
letter instructions to  CALL PGM(QTCP/QTGSRV) PARM(*PORT).

Until you call the program and stop/start your telnet server, telnet will 
still listen on port 23, 
after calling program, the port number you define in your service table 
will be used. 

On V4R4 all should work succesfully without any PTFs or programs.

Tried that.  So far as to IPL the 170 after changing the service table.
Telnet server still was listening at port 23.

it would probably be easier to ask the provider to use a different 
port...I
have
been looking thru the CFGTCP command on the 400,
if you do a '21' (work w/ related tables) and go to '1' (work with service
table
entries) you *may* be able to change the telnet for tcp and udp protos to
something other than 23...then hopefully by restarting the telnet server, 
it
would bind to the new port specified in the services table. There didn't
appear
to be any way to configure the telnet server/daemon using 'Configure
applications' under the CFGTCP menus. If the telnet daemon on the as/400
does
something similar to getprotobyname() as a UNIX host ostensibly would,
changing
the value in the services table should suffice to get the as/400 telnet
server
to listen/bind to a different port.

As for client access, I did a quick look and i didn't see any obvious way 
to
connect to a user-specified port. perhaps there is some registry hacking
that
could enable this? Maybe I just missed it. One would think there *must* 
be a
way!
