-
ins
This section is for users authorized to dial into the MergePoint 5224/5240 SP manager through an
external modem, PC modem or phone card when the one time password (OTP) authentication
method is configured for logins to that target device. With OTP authentication, you supply a
different password every time you dial-in, so no one who discovers the password used for one
session can use that password later to access your account. An OTP is a group of six English words
that are entered all on the same line at the prompt.

When you dial into the MergePoint 5224/5240 SP manager and enter a username, the system
provides a challenge string starting with otp-md5, which tells opiekey to use the MD5 algorithm,
followed by a sequence number and a key and waits for a response.The key includes the first two
letters of the hostname and a pseudo random number. In the following example, the sequence
number is 499 and the seed is on93564.
