- Uri:
-
- Here at Bell-Northern Research, we use Xyplex Annex terminal
- servers. However, the-powers-that-be are getting very paranoid
- about security. Result: we have to use a system called 'SecurID'.
-
- The SecureID system works as follows:
-
- - there is a fixed-part: a user-defined alphanumeric string
- that must be at least 4 characters long (max 8). This value was
- set when a form was filled in and sent to the Network Admin people.
-
- - there is a random-part: a 6 digit (max 8) string that
- changes every minute, generated by the ACE System SecureID
- card - a small, credit-card sized device with a LCD display.
- The user has the card, while the Network Admin people have the
- SecureID module installed on the Xyplex Annex terminal server -
- the two devices must be synchronized with each other.
-
- When the user dials in, the system requires the user
- to enter the 2 parts CONCATENATED together so that
- there is an ever-changing (minimum 10 character) password.
-
- For example:
-
- CONNECT 115200/ARQ
-
- hello there!
-
- Enter username> <userkey>
- Enter PASSCODE: <fixed_part+random_part>
- PASSCODE Accepted
-
-
- Because of this, setting up a SLIP connection to work CANNOT
- be automated - sigh! - you ALWAYS have to type in the 'magic-
- ever-changing' securID code. AND! if you make a mistake, you
- have to get it right on the NEXT try or it will invalidate
- your userid - you have to go back to the Network Admin people
- and have them reset your card and userid.
-
- Anyway, to MINIMIZE the amount of typing, I've added two commands
- to DIP in the commands.c file:
-
- securidfixed <fixed_part>
- securid
-
- The first sets a parameter to the fixed portion of the securID
- key; the second asks the user for the random portion, concatenates
- them together and sends it out the tty port (if the first command
- hasn't been entered yet, an error is printed).
-
- The patch to add this is included in this e-mail message - its
- not rocket-science, but if you are interested in incorporating
- this into DIP, please go ahead.
-
- Caio,
