Hi Kyler,

I'm not sure what exactly goes wrong here, but it seems odd to me that  
you are trying to create a seperate zone file for each host in your  
domain. I don't think a construct like csv2["*.ucmerced.edu."] is ever  
going to work. What you should do instead is create a single zone file  
for your domain, so:

csv2["ucmerced.edu."] = "ucmerced.edu.csv2"

And in that .csv2 file put all your domain records, like the WKS  
record for your domain. I don't know the format of WKS records, so  
I'll give an example A record for * instead from one of my .csv2 files:

*.serenity-irc.net. +43200 a 66.252.28.126

I hope this helps.

Kind regards,

Remco
