Hi, Im trying to run ddclient from my linux machine,

RECEIVE: badauth
FAILED: updating ***@dynu.com: badauth: Bad authorization (username or password)

I have created an IP password and am using that, but it didnt work using my dynu username/password as well.

Have any suggestions?

Here is the contents of my ddclient.conf file - removing username/password/

daemon=60
syslog=yes
pid=/var/run/ddclient.pid
use=web, web=checkip.dynu.com/, web-skip='IP Address'
server=api.dynu.com
protocol=dyndns2
login=***
password='***'
***@dynu.com

Your configuration file looks ok except that the hostname should be ***.dynu.com instead of ***@dynu.com, which is smithresidents.dynu.com in your case.

For more information, you may refer to https://www.dynu.com/DynamicDNS/IPUpdateClient/DDClient

Wow, that was really simple and I totally missed it, thank you!
