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

NAME
make_sockdfr - Generates frozen route file for SOCKS server SYNOPSIS
make_sockdfr [infile [outfile] ] DESCRIPTION
make_sockdfr reads in a plain-text route file for the SOCKS server and produces a frozen route file as the output. Both arguments are optional. The default for infile is /etc/sockd.route; the default for outfile is /etc/sockd.fr. You may specify infile while omitting outfile, but you cannot specify outfile without also speficying infile. The contents of the frozen route file is essentially the memory image of the parsed input 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. FILES
