Connection Methods for Troubleshooting
340 AlterPath OnBoard Administrator’s Guide
Connection Methods for Troubleshooting
This section summarizes how to connect to the OnBoard for troubleshooting
in the event of an IP network failure.
Remote OnBoard administrators can connect to the OnBoard in case of
network failure in any of the following ways:
• By bringing up the Web Manager or logging into the OnBoard’s console
over PPP after establishing a dial-in or callback connection to either of the
following modem types:
• An external modem optionally connected to the OnBoard
• A modem on a PCMCIA modem card optionally installed in the
OnBoard
• By logging into the OnBoard’s console after establishing a dial-in
connection from a terminal emulation program to an external modem
optionally connected to the OnBoard
Local OnBoard administrators can connect to the OnBoard by logging into the
Linux command line through a terminal or computer that is connected to the
OnBoard’s console port.
All of these connection methods must be previously configured as described
elsewhere in this manual. For example, to enable use of a PCMCIA modem
card, the PCMCIA modem card must be installed as described in the
AlterPath OnBoard Installation Guide and configured as described in
“Configuring PCMCIA Cards” on page 169.
Recovering From Login Failure
If no one can log into the OnBoard, you can perform the steps in “To Recover
From Login Failure” on page 341 to reset the root or admin user’s password.
The procedure would be needed, for example, if an attempt to login to the
console as root brings up the following message:
login[212]: FAILED LOGIN
1 FROM FOR root, User not known to the underlying
authentication module
Login incorrect
