I just wanted know how can you say that this is my class homework???
I need this script just to make my work easier so that I don't have to do this manually. Anyway I don't think I will be needing script since I have already done this by just changing bits manually and then calculating integer value.

Hi Guys and gals...
As you know I am getting to grips with POSIX and hit this stumbling block.
Generating two random numbers 0 to 255 POSIXly. Speed in not important hence the 'sleep 1' command.
I have done a demo that works, but it sure is ugly! Is there a better way?

uruk-save
uruk-save(8) SYSTEM ADMINISTRATION uruk-save(8)
NAME
uruk-save - save uruk rc configuration in iptables-save-style format
SYNOPSIS
uruk-save [-6 (save ip6tables rules)]
OPTIONS
-6 (save ip6tables rules)
Don't save iptables rules but save ip6tables rules, for IPv6 filtering.
DESCRIPTION
uruk-save saves the IPv4 rules in /etc/uruk/rc in iptables-save(5)-style format, without invoking iptables(8). If the -6 option is given,
the IPv6 rules (if any) in /etc/uruk/rc are saved, in ip6tables-save(5)-style format. It prints output to stdout; suggested invocation
therefore is
# uruk-save > /var/lib/uruk/iptables/active
or
# uruk-save -6 > /var/lib/uruk/ip6tables/active
. This script is useful if you don't like the default behaviour of the uruk init script, and would like it to load the current uruk rc file
instead of the current active file. Please note: generally you don't need to invoke this script manually: the init script which comes with
uruk is suitable for most cases, it invokes uruk-save if needed.
WARNING
Just as uruk, in order to keep the uruk-save script small and simple, the script does very little error handling. It does not check the con-
tents of the rc file in any way before executing it. When your rc file contains bogus stuff, uruk-save will very likely behave in unexpected
ways. Caveat emptor.
Things will likely break if you do fancy stuff in an rc hook file. For instance, uruk-save saves the filter table only. If you define mangle
or nat tables, things will break.
If your rc file is in verbose mode (i.e. it features set -x) or in no-act mode (i.e. it features iptables='echo iptables'), uruk-save fails.
