[ILUG] Startup services

[alan509]

I want to add some commands to started everytime my linux machine boots up.
Im running redhat 6.1.

I want to add these commands

ipfwadm -F -p deny
ipfwadm -F -a m -S 192.168.0.0/24 -D 0.0.0.0/0
depmod -a
modprobe ip_masq_ftp
modprobe ip_masq_raudio
modprobe ip_masq_irc

can someone tell me the appropritae file to add these into?
And where abouts in the file should i enter them into.


Also i would like somehow to have a command wvdial
to run at 6.00pm and to close at 8am weekdays
and if its possible to get that to run on a friday at 6.00pm and end on a
monday
8.00am
I have little knowledge about these kinds of things so anywya help would be
great.

Thanks in advance ,
