320.
4. Confirm or cancel the disconnect.
Active modem sessions
In the event the primary network fails, you may establish a session to an ACS console server
through a modem/ISDN dial-up connection method. This connection may be established using
the SSH Passthrough client or the ACS console server plug-in. To configure the SSH
Passthrough settings, see Enabling SSH Passthrough on page 224. To configure the ACS
console server plug-in settings, see the ACS console server plug-in online help.
Secure connections
During the initial dial-up connection attempt, the DSView 3 DialUp service will authenticate
the ACS console server and establish a connection using a Point-to-Point Protocol (PPP).
Password Authentication Protocol (PAP) and Challenge Handshake Authentication Protocol
(CHAP) are supported. In addition to the PAP and CHAP methods, a One Time Password (OTP)
authentication may also be used for analog modem dial-up connections. (OTP is not supported
on ISDN modems.) A secret password will be generated for every dial-up request, and each
password will only be valid for a single attempt. Once authenticated, a secure connection will
be established.
For added security, the ACS console server plug-in may also be configured for dial-back
connections. Once authenticated, the dial-up connection will be dropped, and the ACS console
server will dial-back to the DSView 3 server to establish a secure connection. This method does
not support OTP. To configure dial-back settings on the DSView 3 server, see DSView 3
software modem sessions on page 74.
Only DSView 3 software administrators may access the Active Modem Sessions window.
