Summary: When trying to telnet to the 386BSD machine from a non-386BSD
machine, the login/password prompts keep scrolling up the screen.
Hardware: Both machines are AT&T StarStations 386/33Mhz running over a
StarLAN 10 network.
Software: The non-386BSD machine is running AT&T SYSV R4.0.2.1 and
AT&T StarGROUP TCP/IP Software (really Wollongong Group)
version 4.0 Update 1.
Detail: Ping and FTP seem to work just fine. I can telnet to the AT&T
machine from the 386BSD machine without a problem. When I
manually start telnetd on the 386BSD in the debug mode,
I can then telnet from the AT&T machine just fine!! I
have looked at the code for telnetd, but cannot figure out
what is causing the problem. Oh yes, I get the following
diagnostic information when I try to telnet into the
386BSD machine:
STATUS IS :
WILL ECHO
WILL SUPPRESS GO AHEAD
WILL STATUS
DO 33
250
33
Line mode enabled.
ECHO
240
(Get welcome message, scrolling of login/passwd
begins)
When I manually start telnetd with the command
"/usr/libexec/telnetd -debug 557" and then type
"telnet <machine name> 557" fro the AT&T machine, I
get DIFFERENT diagnostic information:
STATUS IS :
DO Line mode enabled.
ECHO
WILL SUPPRESS GO AHEAD
WILL STATUS
DO 33
250
33
Character mode enabled.
ECHO
240
(able to login normally)
telnet seems to be running in character mode here whereas
before it ran in line mode. Telnetd has been compiled with
LINEMODE, USE_TERMIO and DIAGNOSTICS defined.
All comments welcomed. Thanks.
