Login without username and password?

» close window

The Question is:

 
Dear Wizard,
 
I have two machines,one is running Open VMS V 6.2
and one is running Open VMS V 7.1.
 
I want to access the Alpha 4100 running V 7.1
using $ set host "hostname" command but I
don't want that the  machine asks for
user and password.
 
Do you know how to access the host without
user and password?
 
Have a nice day.
 
Sincerely,
 
Luciano Imamura.
 
 
 

The Answer is :

 
  SET HOST requests an interactive login on the target node. There is
  no way to avoid providing a username.
 
  Within a command procedure, you can enter the username and password
  on lines following the SET HOST command (as data).  For example, to
  login to node "TARGET" with username "AUSER" and password "SECURITYRISK"
 
  $ SET HOST TARGET
  AUSER
  SECURITYRISK
  $ EXIT
 
  As should be obvious, coding a password in cleartext in a file is a
  potentially serious security problem. If the account is geniunely
  "open", it's probably better to not have a password at all -- since
  there is no security, why provide the illusion of security.  For
  example, a fully controlled CAPTIVE account can be set /NOPASSWORD
  in the UAF and the following command procedure will connect and login
  without the user seeing a username or password prompt:
 
  $ SET HOST TARGET
  CAPTIVEUSER
  $ EXIT
 
  The only mechanism generally available that is similar to the requested
  behaviour is the automatic login facility (ALF), part of the SYSMAN
  utility.  ALF allows the specification of the origin of the connection.
  ALF is typically and most commonly used with incoming LAT connections
  (SET HOST/LAT or DECservers), or with directly connected serial lines.
  The ALF database assocates a remote user (see the TT_ACCPORNAM value
  in f$getdvi) with a local username, and automatically logs the user into
  the specified local username.  (ALF is not normally used with DECnet.)
 
  DECnet proxies, which allow access for network communications without
  specification of the username and password (or the password) are
  explicitly not supported and not permitted for interactive access.
 
  OpenVMS Engineering is currently evaluating the feasibility of
  implementing a distributed authentication (login) system for potential
  inclusion in an OpenVMS release after V7.2.
 
  The Wizard would generally recommend configuring the systems into a
  cluster, and serving resources across all nodes -- having a similar
  configuration across all cluster member nodes can entirely avoid the
  need to log into another node in the cluster.
