PASSWORD PROBLEMS
-----------------
 
Hi --
 
There have been occasions (such as currently)
when I'm able to "telnet" into my OpenVMS
workstation without difficulty, but _cannot_
login from the system console.  I suspect the
problem has to do with how I have SET TERMINAL
configured (with /ANSI and /NOEIGHTBIT among
other less-likely-problematic settings), if
these options were in force when I set my
password (e.g., a telnet session began with
the "your password has expired" annoncement).
I don't believe the problem is mis-typing or
intermittant keyboard malfunction.
 
Questions:  what SET TERMINAL settings should
I adopt when setting passwords (does it matter?)
for maximum compatibility with logins via the
system console ?  If I telnet from one VMS
machine to another, do these SET TERMINAL
settings need to be in place on both the
local and remote machines (if I need to do
SET PASSWORD on the remote machine) ?  Are
there certain characters to be avoided when
setting passwords (e.g., like $#& etc -- those
users are encouraged[?] to use for security).
 
                        Thanks,
 
                           -- Jim
 
 

The Answer is :

 
  First check for breakin evasion, using SHOW INTRUSION or similar command.
  Breakin evasion will prevent access to the system after a site-specific
  number of login failures have occured, even if a correct password has
  eventually been entered.
 
  Use security auditing to determine the specific cause of the failure.
 
  Make certain you use the return key to end the password, and not the
  enter key.
 
  Typical settings for local terminals -- those settings out in the terminal
  setup screens -- are seven bit, no newline, 1 stop bit, no local echo.
  Occasionally, eight bit no parity.  (The required settings are typically
  application- or terminal-specific.)
 
  The usual OpenVMS settings on the console serial line are seven bit
  autobaud, here is one local (non-autobaud) console line with a VT420
  terminal, after a SET TERMINAL/INQUIRE command has been issued:
 
Terminal: _OPA0:      Device_Type: VT400_Series  Owner: WIZARD
                                              Username: WIZARD
   Input:    9600     LFfill:  0      Width:  80      Parity: None
   Output:   9600     CRfill:  0      Page:   24
