i am absolutly new to ubuntu(linux). i installed ubuntu server 11.4 and am happy for that.
i have read farious forums on general configuration and i have done much. But i cant locate how to configure the firewall to block this programs or ports used. they are over using our company internet bandwidth.we have over 100 computers and i cant go to each computer uninstalling the programs, please i wish to set a policy which will be only allowing traffic from such programs only after working hours. ie from 7:10am- 6:29pm block and from 6:30pm-7:00am allow
i will be glad to find the solution.my email is firstname.lastname@example.org
