# socks.fc(5)

## NAME

```
socks.fc - Frozen configuration file for SOCKS clients
```

## SYNOPSIS

/etc/socks.fc

## DESCRIPTION

The frozen configuration file is produced by *make\_socksfc* and is essentially the memory image of the parsed configuration file. Using the frozen configuration file can reduce the start-up delay of the SOCKS client programs since they no longer have to parse the file contents.

When the SOCKS client starts, it always looks for the frozen configuration file **/etc/socks.fc** first . If that file is not found, it then tries to use the plain-text configuration file **/etc/socks.conf**. If you use frozen configuration, you must remember to run *make\_socksfc* every time after you modify the plain-text file or the SOCKS clients will continue to use the frozen file of a previous configuration.

To find out the contents of a frozen configuration file, use *dump\_socksfc*.
