MAKE_SOCKSFC(8) 					      System Manager's Manual						   MAKE_SOCKSFC(8)

NAME

       make_socksfc -  Generates frozen configuratyion file for SOCKS clients

SYNOPSIS

       make_socksfc [infile [outfile] ]

DESCRIPTION

       make_socksfc reads in a plain-text configuration file for the SOCKS clients and produces a frozen configuration file as the output.

       Both  arguments	are  optional. The default for infile is /etc/socks.conf; the default for outfile is /etc/socks.fc. You may specify infile
       while omitting outfile, but you cannot specify outfile without also speficying infile.

       The contents of the frozen configuration file is essentially the memory image of the parsed input 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.

FILES

       /etc/socks.fc, /etc/socks.conf

       dump_socksfc(8), socks.conf(5), socks.fc(5)
