SSH host: Could not resolve hostname

Question

I am trying to do SSH localforward port setting in VI config file, so that I can connect Hive server to do some R programming.

Steps followed:

Host bdp-*
UserName a6000

Host bdp-prod
HostName pdl001.na.abc.com
LocalForward 10000:pdl002.na.abc.com:10000

ssh bdp-prod

I get this error:

ssh: Could not resolve hostname bdp-prod: Name or service not known

I saw couple of similar issues posted here and viewed some blogs related to this setting but couldn’t figure out what is wrong:

ssh: Could not resolve hostname hnname: Name or service not known

OS-windows, ssh version is 4.1. bdp-prod is alias name for the hostname in config file.

Following up to @JakeGould, the hostname that needs to be resolvable on your computer is pdl001.na.abc.com. Regardless, unless you have a very different version of ssh, the UserName directive is not valid; should be just User. So, the question remains, what OS and what version of ssh? — crimson-egret, Commented Sep 15, 2015 at 15:57

I had the config file created at incorrect location. I now created configuration using

vi ~/.ssh/config

with same content as mentioned in question and able to have local port forward work. Thanks for all of your help.

Some detail on what this does and why you need to do it would make this a good answer.
