You can follow TUX's request processing on syslog by enabling TUX debugging:
1) If your kernel wasn't built with CONFIG_TUX_DEBUG=y, then
   rebuild your kernel with this option turned on.
2) Enter the following comands:
   echo 1 > /proc/sys/net/tux/Dprintk
   echo 1 > /proc/sys/net/tux/TDprintk
3) Follow kernel messages:
   cat /proc/kmsg
4) Open a second terminal session and request the page in question:
   wget -S --spider http://localhost/page.html
5) Tux should have printed verbose messages to your first terminal.
