Re: help ping: unknown host

You need at least one nameserver in your resolv.conf. Looks like your dhcp server is not sending dns entries. Try puting the address of your router in there as:

#router
nameserver 10.0.2.2
# google pdns
nameserver 8.8.8.8
nameserver 8.8.4.4

you could also use opendns or google public dns, etc if your router is not doing dns.
