[one-users] Error in "onevm list": `get_history_host':undefined method `[]' for nil:NilClass (NoMethodError)

[Alvaro Canales]

Hi Tino,

I've been trying to checkout since you asked me to, but I'm getting some
problems.
As I'm behind a proxy, I've followed this rules:
http://subversion.tigris.org/faq.html#proxy, but still no luck.
I can wget to the server and navigate through a web browser, but I can't
ping nor "svn co ...". If I do "nslookup http://svn.opennebula.org/trunk" I
get this:

> Server:        141.52.3.3

It seems that I get a "Non eXistant Domain" problem...
Can you just confirm that you have all server configurations all right?
Thank you!
