Weird configuration
Hi All,

I have a problem with a weird configuration that I need and a few possible solutions came up, but I do not know how to implement none of them.

Let me explain the situation:

I have one switch, one tftp server (linux) and a couple of embedded devices that have the same IP address and it is impossible to be changed, fortunately they have different mac address.

When these embedded devices have to be upgraded, they download automatically its firmware file from the tftp server, but of course all the other devices have to be turned off and in this way it is impossible to work.

Here you have the question:

If I use iptables is there any way to execute a script when a package match with a rule ??

I was thinking in a possible solution but I need to take an action when a package matches with a iptables rule.

If anyone has any idea, please let me know it!!

Thanks.

socks.fc

SOCKS.FC(5)							File Formats Manual						       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.
