It's also a good idea to change the default command prompt while inside the chroot. This will avoid confusion if you have to change terminals. Use this command:
# export PS1="(chroot) $PS1"
Test internet name resolution from within the chroot:
# ping -c 5 google.com
If you can't ping, make sure
/etc/resolv.conf doesn't contain things like
127.0.x.x addresses, if it does, change the
127.0.x.x entry to
188.8.131.52 -- Google's public dns address. Make sure to replace this with your dns of choice once the system is installed.
