Client Software
Fields
• Enable Client Update—Enables or disables client update, both globally and for specific tunnel
groups. You must enable client update before you can send a client update notification to Windows,
MAC OS X, and Linux VPN clients, or initiate an automatic update to hardware clients.
• Client Type—Lists the clients to upgrade: software or hardware, and for Windows software clients,
all Windows or a subset. If you click All Windows Based, do not specify Windows 95, 98 or ME and
Windows NT, 2000 or XP individually. The hardware client gets updated with a release of the ASA
5505 software or of the VPN 3002 hardware client.
• VPN Client Revisions—Contains a comma-separated list of software image revisions appropriate
for this client. If the user’s client revision number matches one of the specified revision numbers,
there is no need to update the client, and, for Windows-based clients, the user does not receive an
update notification. The following caveats apply:
–
The revision list must include the software version for this update.
–
Your entries must match exactly those on the URL for the VPN client, or the TFTP server for
the hardware client.
–
The TFTP server for distributing the hardware client image must be a robust TFTP server.
–
A VPN client user must download an appropriate software version from the listed URL.
–
The VPN 3002 hardware client software is automatically updated via TFTP, with no notification
to the user.
• Image URL—Contains the URL or IP address from which to download the software image. This
URL must point to a file appropriate for this client. For Windows, MAC OS X, and Linux-based
clients, the URL must be in the form: http:// or https://. For hardware clients, the URL must be in
the form tftp://.
–
For Windows, MAC OS X, and Linux-based VPN clients: To activate the Launch button on the
VPN Client Notification, the URL must include the protocol HTTP or HTTPS and the server
address of the site that contains the update. The format of the URL is:
http(s)://server_address:port/directory/filename. The server address can be either an IP address
or a hostname if you have configured a DNS server. For example:
http://10.10.99.70/vpnclient-win-4.6.Rel-k9.exe
The directory is optional. You need the port number only if you use ports other than 80 for HTTP
or 443 for HTTPS.
–
For the hardware client: The format of the URL is tftp://server_address/directory/filename. The
server address can be either an IP address or a hostname if you have configured a DNS server.
For example:
tftp://10.1.1.1/vpn3002-4.1.Rel-k9.bin
• Edit—Opens the Edit Client Update Entry dialog box, which lets you configure or change client
update parameters. See Edit Client Update Entry.
• Live Client Update—Sends an upgrade notification message to all currently connected VPN clients
or selected tunnel group(s).
–
Tunnel Group—Selects all or specific tunnel group(s) for updating.
–
Update Now—Immediately sends an upgrade notification containing a URL specifying where
to retrieve the updated software to the currently connected VPN clients in the selected tunnel
group or all connected tunnel groups. The message includes the location from which to
download the new version of software. The administrator for that VPN client can then retrieve
the new software version and update the VPN client software.
