Capturing Clientless SSL VPN Data
Capturing Clientless SSL VPN Data
The CLI capture command lets you log information about websites that do not display properly over a
Clientless SSL VPN connection. This data can help your Cisco customer support engineer troubleshoot
problems. The following sections describe how to use the capture command:
•Creating a Capture File
•Using a Browser to Display Capture Data
Note Enabling Clientless SSL VPN capture affects the performance of the security appliance. Be sure to
disable the capture after you generate the capture files needed for troubleshooting.

Creating a Capture File

Perform the following steps to capture data about a Clientless SSL VPN session to a file.

(See Using Applications)
To use mail, start Application Access from the
Clientless SSL VPN Home page. The mail client
is then available for use.
Note If you are using an IMAP client and you lose your mail server connection or are unable to
make a new connection, close the IMAP application and restart Clientless SSL VPN.
Other mail clients We have tested Microsoft Outlook Express
versions 5.5 and 6.0.
Clientless SSL VPN should support other SMTPS,
POP3S, or IMAP4S e-mail programs via port
forwarding, such as Lotus Notes, and Eudora, but
we have not verified them.
