That did it. Seems to be working now, thanks!   

Hi,

I'm new to mining in general ... I signed up for multipool and started cudaminer like this:
$ cudaminer -H 1 -o stratum+tcp://pool1.us.multipool.us:7777 -u <username> -p <password>

Result:
[2013-11-24 00:21:03] 1 miner threads started, using 'scrypt' algorithm.
[2013-11-24 00:21:03] Starting Stratum on stratum+tcp://pool1.us.multipool.us:7777
[2013-11-24 00:21:14] Stratum connection failed: Couldn't resolve host 'pool1.us.multipool.us'

[2013-11-24 00:21:29] Stratum authentication failed

I'm having the same problem with pooler miner:
$ minerd -o stratum+tcp://pool1.us.multipool.us:7777 -u <username> -p <password>

But if I do:
$ nslookup pool1.us.multipool.us
Non-authoritative answer:
Server:  homeportal
Address:  192.168.1.254

Name:    pool1.us.multipool.us
Addresses:  162.243.142.31
          162.243.148.179

Why can't I connect? Am I missing something? Thanks for any help.

I am new to mining. I started cudeminer like this:
$ cudaminer -H 1 -o stratum+tcp://pool1.us.multipool.us:7777 -u <username> -p <password>

Why can't cudaminer resolve the host?

UPDATE:
