Troubleshooting the SSL VPN Client

This chapter covers the troubleshooting of the SSL VPN browser plug-in and 

the agent. The following topics are described in this chapter:

Connection Logs

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. 

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
