I am really not interested in getting error mails for crap like people  
scanning to see if I have some outdated version of phpmyadmin,  
roundcube, etc… the typical stuff hackers are will look for.

So within my application controller before it sends me an e-mail, I want  
to search to see if it’s a valid ‘controller’ that’s being requested  
before it actually sends me an error e-mail.

Thus I need something like…

if [LIST\_OF\_MY\_CONTROLLERS].include?(params[:action])

how do I get a list of my controllers?

I don’t know of a good way to list of all your app’s controllers (you  
_could_ search for all Constants that descend from  
ApplicationController, but that seems prettttty grody). I’m _assuming_  
the emails are being sent from a rescue\_from or somesuch similar in your  
ApplicationController… would it work for your requirements to instead  
just create a catchall route and then send a 404 error/page?

well I am certainly trying to deal with a ‘rescue\_from’.

In essence, all the various crap that people scan web servers in hopes  
of finding exploitable software for are generating 404 errors…that’s  
to be expected.

I just don’t want to see an e-mail if the URL’s they are requesting  
aren’t a controller in my application.

Obviously I can provide a defined list of my controllers to this but  
that is rather analog and rails should be able to give me a list of my  
controllers or an array that I can flatten.

Thanks

this gets me awfully close…

@conts = []  
controllers = Dir.new("#{RAILS\_ROOT}/app/controllers").entries  
controllers.each do |controller|  
if controller =~ /\_controller/ and not controller.index(".swp") then  
cont =  
controller.gsub(".rb~","").gsub(".rb","").gsub("\_controller","")  
@conts \<\< [cont]  
end  
end  
and I can flatten @conts at that point and I could spend the time to  
toss .svn out but for now, I’m good.
