Re: Non-hidden password in VTxxx emulation

2009/3/4 Scott Klement <midrange-l@xxxxxxxxxxxxxxxx>:
Really, your best option is to telnet from the PC directly to the
RS/6000 device -- preferably via a tool like Putty.

If that's not an option (usually due to security) another method that's
VASTLY more secure than going through 5250 is to run an SSH server on
your AS/400, and use it to create an SSH tunnel, then route the telnet
from the PC through the SSH tunnel.  The result will be an encrypted
channel that still goes through your AS/400, and still must pass it's
password validation, but is encrypted and allows proper VT100 (or
better, xterm) emulation through the channel.

The TELNET tool on OS/400 is about the best it can be, considering that
it has to go through 5250 -- but it'll never work quite right.

Scott,

Thanks for a very full answer. We will investigate the SSH tunnel
suggestion if management decides the displayed passwords are an
important enough issue.
