# sockd.fr(5)

Frozen route file for multi-homed SOCKS proxy server

## NAME

sockd.fr - Frozen route file for multi-homed SOCKS proxy server

## SYNOPSIS

**/etc/sockd.fr**

## DESCRIPTION

The frozen route file is produced by *make\_sockdfr* and is essentially the memory image of the parsed route file. Using the frozen route file can reduce the start-up delay of the SOCKS server program since it no longer has to parse the file contents.

When the SOCKS server starts, it always looks for the frozen route file **/etc/sockd.fr** first. If that file is not found, it then tries to use the plain-text route file **/etc/sockd.route**. If you use frozen route file, you must remember to run *make\_sockdfr* every time after you modify the plain-text file or the SOCKS server will continue to use the frozen version of a previous route file.

To find out the contents of a frozen route file, use *dump\_sockdfr*.
