Good morning,
I am trying to execute a linux command from inside my controller. It
works on my development machine, but does not work in production. Here
is the code.
def get_whois
@the_site = Site.find_by_id(params[:id])
unless @the_site
flash[:error] = "Site could not be found"
redirect_to :action => :index and return
end
@the_site.whois = `whois #{@site.domain}`
@the_site.save
flash[:notice] = "WHOIS information captured"
redirect_to :action => :show, :id => @the_site.id
end
Does anyone know why this doesn''t work in production mode? It works
fine in development...
Any advice is appreciated.

What is the error? Does the production machine even have that command available? Since whois connects to external servers, do you know if that connection is allowed (i.e. is there a firewall or some other network filtering going in?). Lots of variables.

Man I feel dumb. I wasn''t getting any error I could see, but it became clear as day once I sshed onto the live server. It turns out WHOIS wasn''t installed on the Ubuntu server. So I just did: sudo apt-get install whois I love how the weirdest problems have such simple solutions (sometimes). -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
