RE: Change telnet to another port?

[Chris Bipes <rpg@xxxxxxxxxxxxxxx>]

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

Subject: Re: Change telnet to another port?


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!

it is worth noting that the as/400 telnet client, when prompted and showing
all
parameters, will enable the use of a user-specified port to connect to.

as for other clients, it just depends on whether the programmer(s) enabled
another port to connect to.

if your provider is nice, they may accommodate you by switching to some
other
port. :-)
