dump_sockdfr

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

NAME

       dump_sockdfr -  Display contents of frozen route file for SOCKS server

SYNOPSIS

       dump_sockdfr [infile]

DESCRIPTION

       dump_sockdfr reads in a frozen route file for the SOCKS server and produces a listing of its contents on the standard output.

       The argument is optional; if omitted, /etc/sockd.fr is assumed.

       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.

FILES

       /etc/sockd.fr, /etc/sockd.route

SEE ALSO

       make_sockdfr(8), sockd.fr(5), sockd.route(5)
