[K12OSN] OT: Limit Network Access by time

[Phil Benson]

Another way to do this is to just remove the gateway from the machine and
then bring the gateway back with a cron job.

#down internet connection at 9:00 PM CST
00 21 * * 0,1,2,3,4 /sbin/route del default gw 192.168.1.1
#Bring up internet connection at 6:00 AM CST
0 6 * * 0,1,2,3,4,5 /sbin/route add default gw 192.168.1.1

I actually found this at IPCop's website:
----------------------------------------------------------
Can I disable the internet connection from 11pm to 6am?
Add a cron job to do this. The following will stop all internet
interface traffic from 11pm to 6 am. You can either use the entire
ruleset, or eliminate the ones you don't use, ie, if you don't have a
modem, leave out the modem lines, and vice versa. Using them all will
not hurt anything.

0 23 * * * /sbin/ipchains -I ethout 1 -i eth1 -j DENY
0 23 * * * /sbin/ipchains -I ethin 1 -i eth1 -j DENY
0 23 * * * /sbin/ipchains -I mdmout 1 -i ppp0 -j DENY
0 23 * * * /sbin/ipchains -I mdmin 1 -i ppp0 -j DENY


0 6 * * * /sbin/ipchains -D ethout 1
0 6 * * * /sbin/ipchains -D ethin 1
0 6 * * * /sbin/ipchains -D mdmout 1
0 6 * * * /sbin/ipchains -D mdmin 1

----------------------------------------------------------

Would I just add the first two lines of these sections to crontab?  I
will give it a shot.  I was thinking I could put the dorm staff on the
Orange network, and the students on the Green network, then just disable
the green.  Opinions....

Isn't ipcop a spinoff of smoothwall? Which includes squid?
