Internet connection works OK before chrooting into hda5/remaster/KNOPPIX. From chroot I can ping 216.239.57.99 (Google) OK but can't ping google.com.
I copied /etc/resolv.conf from the running copy (actually a 'toHD' install on hda7) to the chroot /hda5/remaster/KNOPPIX/etc/resolv.conf but still no go.
resolv.conf is:

root@ttyp0[/]# cat /etc/resolv.conf
# Insert nameservers here
nameserver 192.168.2.1

which is the address for my router & seems to be correct as confirmed by:

root@ttyp0[knoppix]# nslookup google.com
Note: nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead. Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.
Server: 192.168.2.1
Address: 192.168.2.1#53

Non-authoritative answer:
Name: google.com
Address: 216.239.37.99
Name: google.com
Address: 216.239.39.99
Name: google.com
Address: 216.239.57.99

What else should I try?
Thanks
