downtime,
Look carefully in the lower left corner on the label of your power supply and you will see polarity information.
That won't help with the identified conductor (ridge), there are times when a meter or continuity tester is required to be sure.
On a similar power supply I have, the identified conductor (white stripe) goes to the center contact (+). YMMV
HTH, Jim

With great power there must also come great responsibility.
Please administer your forum! There's no excuse for letting 10 pages of spam (and counting) be posted.
It is somewhat useless in it's present condition.

The nameserver in /etc/resolv.conf is incorrect, and according to man interfaces, dns-nameservers is not an allowed entry. The static Method
This method may be used to define ethernet interfaces with statically
allocated IPv4 addresses.

netmask netmask
Netmask (dotted quad) required
broadcast broadcast_address
Broadcast address (dotted quad)
network network_address

metric metric
Routing metric for default gateway (integer)
gateway address
Default gateway (dotted quad)
pointopoint address

media type
Medium type, driver dependent
hwaddress class address
Hardware Address. class is one of ether, ax25, ARCnet or
netrom. address is dependent on the above choice.

Instead of talking you through the joys of the vi editor, it may be just as easy overwrite /etc/resolv.conf with the proper entry: # echo "nameserver 195.121.1.34" > /etc/resolv.conf && echo "nameserver 195.121.1.66" >> /etc/resolv.conf Sorry about the dig command, it is not installed. HTH, Jim |

You've got networking issues.
Please post the copied output from the following commands:
# ifconfig
# cat /etc/resolv.conf
# route
# ping 192.168.1.254
# dig yahoo.com
HTH, Jim
