OpenVPN Connection Manager CGI script
A small perl CGI script to monitor and manage VPN users on an open VPN server. An expansion of openvpn.cgi as distributed with Net-OpenVPN-Manage-0.02.   Requires Net-OpenVPN-Manage and Net-Telnet-3.03 Perl modules. See comments at the beginning. Use with almost any webserver, but mongoose is recommended.

FwBuilder log scan tool
A Tcl script that may be used to search one or more kernel logfiles for interesting firewall entries. Not quite complete, but many useful search features are operational. Logs are assumed to be in the format produced by Firewall Builder. We built this tool because there are times when grep is just not sufficent.
