Yes, you would need to utilize the time patch. Go to the following Howto to read up about it. http://www.netfilter.org/documentation/HOWTO//netfilter-extensions-HOWTO-3.h tml#ss3.19 Brandon Broyles ----- Original Message ----- From: Steffen Bisgaard - Xtrasource To: netfilter@xxxxxxxxxxxxxxxxxxx Sent: Wednesday, October 22, 2003 3:44 PM Subject: Time changes Hallo list, A quick question: Is it possible to block access to and from a PC (say 10.2.0.3) at a specific time, for example 21:00, and re-enable it at 08:00 the next day using iptables - and if so how?? Yes this is the kids PC... It used to be real simple with ipfw - I can't remember the syntax but something along the lines of ipfw -add (or -remove) deny (or allow) 10.2.0.3 all Any ideas? Or do I need two separate iptables scripts?
