Serial Port Profiles

Remote Password Complete this field only if you have specified PAP or CHAP (security

protocols) in the

Security field, and

z you wish to dedicate this serial port to a single remote user, and this user

will be authenticated by the IOLAN, or

z you are using the IOLAN as a router (back-to-back with another IOLAN)

Remote password means the following:

z When PAP is specified, this is the password the IOLAN will use to

authenticate the remote device.

z When CHAP is specified, this is the secret (password) known to both ends

of the link upon which responses to challenges will be based.

Remote Password is the opposite of the parameter Password. Your IOLAN

will only authenticate the remote device when

PAP or CHAP is operating.

Field Format: You can enter a maximum of 16 alphanumeric characters.

Authentication

Timeout

The timeout, in minutes, during which successful PAP or CHAP authentication

must take place (when

PAP or CHAP are specified). If the timer expires before

the remote end has been authenticated successfully, the link will be terminated.

Range: 1-255

Default: 1 minute

CHAP Challenge

Interval

The interval, in minutes, for which the IOLAN will issue a CHAP re-challenge

to the remote end. During CHAP authentication, an initial CHAP challenge

takes place, and is unrelated to CHAP re-challenges. The initial challenge takes

place even if re-challenges are disabled. Some PPP client software does not

work with CHAP re-challenges, so you might want to leave the parameter

disabled in the IOLAN.

Range: 0-255

Default: 0 (zero), meaning CHAP re-challenge is disabled

Enable Roaming

Callback

A user can enter a telephone number that the IOLAN will use to callback

him/her. This feature is particularly useful for a mobile user. Roaming callback

can only work when the

User Enable Callback parameter is enabled. Enable

Roaming Callback therefore overrides (fixed) User Enable Callback.To use

Enable Roaming Callback, the remote end must be a Microsoft Windows OS

that supports Microsoft’s Callback Control Protocol (CBCP). The user is

allowed 30 seconds to enter a telephone number after which the IOLAN ends

the call.

Default: Disabled
