Failsafe error in rails 2.1 RC1 - ip spoofing

Hi All,
I am getting the following errors in my app using RC 1 of Rails 2.1.
errors only appear to be happening for search engine bots/crawlers, but
since my site needs to be indexed, I would like to get rid of them. Does
anyone know if there is a fix, or perhaps a config option not to check
ip spoofing?

/!\ FAILSAFE /!\ Sat May 31 11:12:54 -0400 2008
Status: 500 Internal Server Error
IP spoofing attack?!


did you try this patch?

Thanks for the link to the patch, but why would one have to patch rails
order to avoid these failsafe errors. They are being caused exclusively
yahoo’s crawlers/bots, but isn’t everyone else’s site being crawled by
as well? Is everyone else’s site getting these errors as well?

i’m seeing this a lot with the release version of rails 2.1

Please, can you specify how to aply the patch, I do:

MacBook:rails$ patch -p0 < forwarded_client_ip_with_test.patch
can’t find file to patch at input line 15
Perhaps you used the wrong -p or --strip option?

Can you help me?

Is anyone else seeing these errors? I’ve just hit upon it while
setting up a cluster. Rails 2.1.
