5.1Debugging the SSL VPN Client

You can configure the client to run in debug trace mode. In this mode, the SSL VPN browser plug-in logs all of its major activities into an ASCII file. These ASCII files, also known as log files, are stored in the file system.

On Windows 95/98/ME, you need to specify the names of these files in the fol- lowing format:

hooklog<num>.txt

nssslvpn.txt

Use the hooklog<num>.txt file for debugging the interception messages gen- erated by the client and the nssslvpn.txt file for debugging the client. You can also send these files to the Citrix customer support department for assistance.

Note You need to periodically delete the hooklog<num>.txt file.

On Windows NT/2000/XP/2003, you can specify the file name. The default file- name is c:\nssslvpn.txt.

You can use these log files to debug and troubleshoot the plug-in. Kindly mail the log files to Support if you encounter any problems. To enable the creation of these files, select the Enable Client Trace option in the Trace pane of the Configuration window.

You can debug the plug-in by studying the traces that it generates when it is active. The trace messages are stored in the file specified in the ‘Log Filename’ field.

The SSL VPN client side trace can have different levels of detail. You can select
