Remote Access (PPP) Profile

Overview
The Remote Access (PPP) profile configures a serial port to allow a remote user to establish a PPP
connection to the IOLAN’s serial port. This is typically used with a modem for dial-in or dial -out
access to the network or a wireless WAN card.
Functionality
There are two options for PPP user authentication:
1. You can configure a specific user/password and a specific remote user/password per a serial port.
2. You can create a secrets file with multiple users and their passwords that will globally
authenticate users on all serial ports.
You can use configure PPP authentication in the configuration or in the secrets file, but not both.
If you want to use a secrets file, you must download the secrets file to the IOLAN for CHAP or PAP
authentication; the files must be downloaded to the IOLAN using the names chap-secrets and
pap-secrets, respectively. The file can be downloaded to th e IO LAN un d e r th e Custom Files
option by selecting the Download Other File parameter.
In the Remote Access (PPP) profile, you mu st also specify the Authentication option as PAP or
CHAP on the Authentication tab, but must leave the User, Password, Remote User, and Remote
Password fields blan k.
An example of the CHAP secrets file follows:
# Secrets fo r authenticati on using CHAP
# client server secret accep table local I P addresses
barney fred flintstone123 4567890 192.1 68.43.1
fred barney wilma 192.1 68.43.2
An example of the PAP secret file follows:
# Secrets fo r authenticati on using PAP
# client server secret accep table local I P addresses

Associated Port When a server or router has its console port connected to one of the serial ports
on this IOLAN and that server/router is also powered by this RPS, the
server/router serial port number should be entered here. This will give you
direct access to some RPS commands when managing that server or router
(using Telnet or SSH).
