3.3.3. /proc/net/tux Parameters
After starting TUX, the /proc/net/tux directory contains the file stat. This file contains
statistics on every allocated request structure. As this works evenif TUX_DEBUG is turned off,
this should help debugging things a bit more. It can also be used to calculate file download
status. For example, TUX/FTP - the 100*f_pos/filelen gives the current progress of down-
load.
It is possible to bind the logger thread to any particular CPU (or group of CPUs), so you can
localize IO, via /proc/net/tux/log_cpu_maskThe default is to run on any CPU.
3.3.4. Required Parameters

• serverport
• clientport
• DOCROOT
The DOCROOTfor TUXmust be thesame document root directory as Apache orother user-space
daemon running as the assistant web server for TUX to properly redirect requests.
