I'm travelling on business and trying to use the hotel-supplied internet. I'm
using a Telkonet Bridge through the building's wiring. (Laptop -> Cat-5
cable -> Telkonet -> building wiring.) My laptop is an up-to-date Gentoo,
2.6 kernel, IBM Thinkpad R51.
DHCP works to give me an IP address, and sets the default
gateway. /etc/resolv.conf gets automatically changed to one line:
nameserver 168.95.1.1
While the network connection works fine (I can ping any valid IP, such as my
email server, my home network, etc). However, DNS name resolution is not
working. Here's a typical session:
orion root # /etc/init.d/net.eth0 stop
* Running predown function
* Bringing eth0 down
* Releasing DHCP lease for eth0...
[ ok ]
* Stopping eth0...
[ ok ]
orion root # /etc/init.d/net.eth0 start
* Running preup function
* Wireless extensions not found for eth0
* Bringing eth0 up via DHCP...
dhcpcd: MAC address = 00:0d:60:78:92:1f
dhcpcd: your IP address = 192.168.1.137
dhcpcd: orig hostname = orion
dhcpcd: orig domainname = (none)
[ ok ]
* eth0 received address 192.168.1.137
orion root # ping www.utk.edu
ping: unknown host www.utk.edu
orion root # ping 160.36.178.162

What's not set up right? Is there something on the network filtering me out?
Am I missing a configuration setting?
Note: I get the same behavior from a Knoppix boot.
Peace,
