Known Errors

These are the known errors in our products, logged as reported with versions and platforms affected as well as corrections and work-arounds.

This list is largely historical, since it records all problems that have been reported throughout G&R history. Only the most recently reported problems still exist, unless you are using a very old copy of the product, in which case you should update the product to the most recent version.

E1123: Ggate/Telnet, default values for echo and SGA

Product: Ggate Telnet support
Platform: All
Status: fixed for 6.4, fix available for 6.3
Last updated: 2006-07-05 09:45:36

The Ggate support for Telnet clients used the RFC 857 standard
default for echo (won't echo) and the RFC 858 standard default for SGA
(won't Suppress Go-ahead). This relies on clients requesting echo
and SGA if they need it.

The implementation in the Bull MainWay is the opposite of the
standard in the RFCs. The MainWay default for asynchronous terminals
is echo and SGA.

Since the primary purpose of the Telnet implementation in Ggate is to
support third party clients that have previously been qualified for
connections via a MainWay, and since these third party clients often
have a minimal (or non-existent) Telnet negotiation engine, the
defaults for Ggate Telnet have been changed to use echo and SGA even
if the client doesn't request them. This behaviour can be
standardized if necessary using parameters to Ggate (-TELSGA ON/off
and TELECHO (ON/off), or as Gline parameters for a Telnet CONAME in the
dsa.cfg file.

The options have also been tied together, as in the MainWay
implementation (and as recommended in RFC858). If a client uses the
the secondary dialog command ($*$EC OFF) to turn off the echo, then
the Ggate Telnet negotiation engine will announce that it will turn
off echo, but also stop suppressing Go-ahead (won't echo, won't SGA).
