    First, make sure you can route to everything

    ping 68.80.0.12
    traceroute 68.80.0.12

    if either of these fails, you have other issues (routing, etc.)
    This *could* be a firewall issue. nslookup uses the same underlying
    stuff as ping and web surfing to do the name to address mapping.

    Copy /etc/nsswitch.files to /etc/nsswitch.conf
    edit /etc/nsswitch.conf and add "dns" to the hosts line.
    try telnet/ping again.

    Also, just for fun, do a "ifconfig -a" and check your netmask, etc.
    Most often the netmask should be ffffff00, but your hub may be using something
    else.
