To disconnect one or more target device active sessions:
NOTE: To disconnect a session, a user must have unit view access rights and a preemption level that is greater
than or equal to the session user.
1. In a Units View window containing target devices (see Accessing Units View windows on
page 118), click on a target device Status field. The Active Sessions window for that target
device will open.
2. Click the checkbox to the left of the sessions. To disconnect all sessions, click the
checkbox to the left of Duration at the top of the list. (If you do not have permission to
disconnect an active session, you will not be able to select its checkbox or the checkbox at
the top of the list.)
3. Click Disconnect. A confirmation dialog box will appear.
For virtual media sessions on supported KVM switches - If you attempt to disconnect
an active virtual media session or a KVM session that is locked to a virtual media
session, a confirmation message is displayed, indicating that any virtual media
mappings will be disconnected. Confirm or cancel. See Using Virtual Media on page
319.
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 222. 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 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
