Hi Guys...

Is there a way to be able to set times for certain IP addresses on the
Internal network to access the Internet?

Eg...

PC 192.168.1.2 should only have accessto the Internet during 9.am to 5pm Mon
to Fri only.
Would I need to set this ip in ipf.rules?

I use a BSD PC as a gateway and mailserver, but I also have to use a Windows
PC to be able to run Winrote to set up a time table.

I would much rather do it all thru the BSD PC.

Any help would be great...

Cheers DL

The only way I see is to have several rule sets, and switch them around
based on a cron job.

man 5 cron

How difficult can it be to reload a ruleset from a cronjob?

1. FREE BSD fine-grain timer

hi, folks,

I need a fine-grain timer (33us) to revise a network interface driver.
If I change 'hz' and rebuild the kernal, do it works?

Usually, 'hz' is equal to 100. So, the timeout resolution is 10 ms.

If I changed to 'hz', I am wondering if other kernal parts which use
'hz' may be messed.

DO you have any ideas? Thanks for your inputs.
