Authenticate with an IP address : LoginGenerator

Is there a way to authenticate with an IP address? I’m using the
LoginGenerator, but would like to bypass the "before_filter
:login_required
" if a user is in a correct IP range…

Anyone know of a solution?

Thanks!

I believe you can get the user’s IP with the remote_ip method on the
request object in your controller.

def index
ip = request.remote_ip

now you can check this ip against a table, or a range, etc.

Sorry, just realized you were asking about LoginGenerator.

Never mind :slight_smile:

Wouldn’t it be easier to use a firewall?

Anyone else have any ideas? To me, it’d seem like getting the user’s IP
address, comparing it to a range, and then use a statement that gives
the user a correct password and login automatically.

The site is on a remote server, not hosted internally. Would a firewall
still be possible?

I’m inferring from your prior mails that what you want to do is restrict
your site so that it may only be accessed by people coming from a
specific part of the internet (identified by source-IP range). I’m
assuming you’re NOT trying to give people different authorizations based
on where they are coming from. If I guessed right, you need a firewall
to solve this problem. You may be able to diddle iptables on your remote
server if you can. If you can’t, and your hosting provider doesn’t give
you a firewall, you need a new hosting provider.

If you’re trying to actually authorize people based on source-IP
addresses, I’d recommend you not do that.

I was actually trying to authorize people based on their IP. It’s a site
that needs very minimum security so it’s not a huge problem.

Does Textdrive offer a firewall?

I can’t speak for TextDrive but I have only heard bad things about them.
But I was wrong- if you want to authorize people based on theiir source
address (for example, showing them different content if you infer that
they are coming from one company as opposed to another) then a firewall
isn’t enough to solve the problem.

What’s wrong with Jeff C.'s suggestion from upthread:

Nothing, but that would just be getting me the IP, I was wanting to know
how to use a User’s IP to autheticate through the LoginGenerator.

Are you sure your users will have unchanging IP addresses? Proxies and
load balancers can wreak havoc on IP-based authentication. Many ISPs
will assign different IPs each day, and some are even worse. AOL, for
example, may have a different IP address for each request from one of
their users’ browsers.

But if you’re OK with that, you can get the IP in an action directly
from the environment hash:

ip_addr = request.env[“REMOTE_IP”]

Hmm… But I just looked it up and there is a more robust method:

ip_addr = request.remote_ip

that specifically checks for well-behaved proxies, so it will work in
more (but not all) situations.

I know that others have kind-of hinted around this, but just to be
really clear…

You do realize that IP addresses are easily faked, right? They are a
horrible choice for defining who a user is, or what rights that person
should have.

I’m guess I’m not getting this (and I’m sure I’m not being of much help
to you). Are you trying to solve a narrow technical problem related to
LoginGenerator? Or are you actually trying to impute some kind of
identity characteristics to a source-IP address? If the latter, then
why? Are you trying to save people the inconvenience of logging in? If
you really don’t care about the security of your site (as you implied
above), then why not do a normal authentication database and drop a
persistent cookie so your users will only have to log in once?
