Adds ident authentation to your express.js routes.
How to use (in CoffeeScript):
checkIdent = require 'ident-express' app.get '/foo', checkIdent, (req, res) -> # Do something with req.ident console.log "I think you are " + req.ident
Ident is described in RFC 1413. One important thing to note is that the information returned by identd should only be trusted if you trust the machine running the identd, which is the machine from which the connection has been made (the user/browser/service that is making the GET/POST/PUT request).
If your express.js app is behind a reverse-proxy such as nginx
then the IP address that express.js sees will be those of nginx,
not of the original HTTP request that was made to nginx. nginx
can set headers that reveal the real IP address. Ident express
will make use of the headers
which can be set by using the following fragment of nginx config:
proxy_set_header X-Real-Port $remote_port; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Server-IP $server_addr; proxy_set_header X-Server-Port $server_port;
