Redhat 6.x -
I have a .sh script to update my IP with a dynamic DNS server that I run by hand each time i boot my PC. I run a PPP connection to the net and IP masq on the same box, so the PPP hangs up once in a while. I want to be able to, every 30 minutes or so, execute the file dns_update.sh. I think I need to use Cron to do this, but my Cron knowledge is very lacking. Could someone help me out with this? Much appreciated.
