Okay if your TCP/IP setup is complete you should get a response back from the
server if it's up. Try some other IPs...
ftp.apple.com = 17.254.0.37
www.altavista.com = 204.152.190.65

If these don't work...I'd say you probably have something wrong with your default
route. that's another matter altogether, and if it is broken, it would explain why
dns won't work!

To fix a defaultroute problem, make sure that the 'defaultroute' option is included
when you run pppd to connect to the server. The easiest way to do this is probably
using the netcfg tool mentioned before. Alternatively, if you're using a script,
make sure that 'defaultroute' is somewhere after the 'pppd' in the script.  If
you're using 'ifup ppp0', make sure that
/etc/sysconfig/network-scripts/ifcfg-ppp0 has 'DEFROUTE=yes' in it. Again, this is
on my RedHat box, can't say for other distros.

I would try removing the line that says 'search'. Remove only that line, and try
again. More comments below:

use 'rpm -q bind' to see if you have it installed. (RedHat/RPM distributions only)

this was probably supposed to be the /etc/services file, not /etc/networks? You
should probably have the following lines in /etc/services:

domain          53/tcp          nameserver      # name-domain server
domain          53/udp          nameserver

use 'grep' to search a file. e.g.

'grep dns /etc/nsswitch.conf' looks for the string 'dns' in /etc/nsswitch.conf
see 'man grep' for more info about this. BTW, my /etc/nsswitch.conf has this line
in it:
hosts:      files nisplus nis dns

good luck...you're almost there.
