Automator to run terminal commands?

Is this possible? I need automator to run this set of commands:

dscacheutil -flushcache
sudo sysctl -w net.inet.tcp.rfc1323=0
sudo sysctl -w net.inet.tcp.recvspace=32768
sudo sysctl -w net.inet.tcp.sendspace=32768
sudo sysctl -w net.inet.tcp.win_scale_factor=1
sudo sysctl -w net.inet.tcp.sockthreshold=0

Every 6 hours or so. It is for playing WoW, if I dont do that like once every other day or so, WoW will just kill the connection every time I log in, and this fixes it. It would be nice to not have to worry about it.

I've never used automator before so idk if this is even possible..

nice, how do i make it run at a certain interval?

eh also i need to enter my password on the second command, seems to be hanging it.
