kubuntu 9.10 can reach network but not internet

babag · 04-15-2010, 05:17 PM

can ping router but not www.google.com or 74.125.45.100.

can connect to samba shares on the mac and pc in the local network.

when i try to ping www.google.com i get 'unknown host.'
when i try to ping 74.125.45.100 i get 'network is unreachable.'

resolv.conf has the same nameservers as the mac and pc, both of which can
reach the internet without issue.

any ideas?

edit:
route -n says my destination is 192.168.1.0 and gateway is 0.0.0.0

my router's address is 192.168.1.1. should that be what the destination should say?
how do i change it?

thanks,
BabaG

Have you checked the firewall settings on the kubuntu machine?

i got the internet working by editing /etc/networking/interfaces
which had incorrect info in it. in doing so, however, i've now lost
my connection to samba shares. in dolphin i can click the left-pane
network icon and get its various options.

if i click the network icon that appears, i see the mac pro on the
network. if i click that, i see various options, including samba.
clicking the samba options produces nothing but an error that it
could not connect.

if i click the samba shares option that appears after a left-pane
network icon click, i see an icon for mshome, the workgroup for
the local network. clicking the mshome icon produces nothing, not
even an error.

the pc on the network does not appear at all when clicking the left-
pane network icon.

i am able to ping both the mac pro and the pc.

thanks for the help so far,
BabaG
