Hi, I am relatively new to linux and I have been playing with setting up and connecting DNS with DHCP. I was following a tutorial and believe I have set up everything correctly however I cannot ping the host name given to the other machine on my network. The output to syslog looks fine (I have included below) and a record has been added to the .zone file in var/cache/ but I have no idea how to fix it. Any help would be appreciated thanks.
