Bsd wifi access point

Instead I made a new instance of apache just to listen on port of the wireless IP address and handle the crazy wireless URLs. I include the full httpd. The supplied regular expression is matched against the URL-path, and if it matches, the server will substitute any parenthesized matches into the given string and use it as a filename.

My regular expression,. Since scripts are enabled by extension on this server the CGI script runs and instead of www. The notice. The first job is simple, it just throws some HTML out. People probably were surfing to www. It's friendly, tells them what's up, and gives them a chance to accept my policy. Then, the same notice. When they accept the policy the script says thanks and adds their IP address to the list that are to be unblocked.

A separate daemon process handles unblocking the wireless IP address by modifying the firewall rules. Specifically it adds a rule to bypass the "forward http to the webserver" and "deny everything else" entries in the ruleset.

I use a the daemon process because I want to be able to re-block the IP address after some amount of time has elapsed.

Since the CGI script is only invoked as a response to to a web hit it is not able to re-block an IP after a timeout. The last thing the CGI script does is redirect the wireless user to the original website to which they surfed. The CGI script is included here for your reading pleasure but is also included again with support HTML files in the tarball at the end of this article.

This perl script is a daemon process in that it is always running in the background on the FreeBSD machine. Every few seconds it wakes up and The script which I called wireless-auth is listed in this section but is also included in the constantly-referred-to tarball at the end of the article. The rules it adds to unblock a new wireless client's IP address look like this:.

Rules like this are part of one ruleset set 1 so that they can be deleted easily in one ipfw command when the firewall is being rebuilt.

All that they do is allow one particular wireless IP address to skip around this part of the firewall rules:. You can use the ipfw to limit the amount of bandwidth that your wireless clients can use by setting up some pipes. Here's an example:. They get reasonable performance that doesn't ever swamp my internal subnet. I have to give a plug to my ISP because it's a rare thing in this age of fascist service providers to find one with a liberal and progressive policy towards bandwidth sharing.

I've also found Speakeasy to be pretty responsive and customer oriented when I've had to deal with them. Make sure drivers are loaded for the wireless interface.

For Atheros based cards you'll need the following single, one-line command:. For any wireless card, including Atheros cards, make sure we have all the proper wireless modules loaded. The following is a long line, but it is a single, one-line command:. Perform the following commands as root. Create a pf. At this point, assuming you followed the directions and had no errors, you should have a functional wireless access point using WPA and a wired LAN that is connected to the upstream link.

Your firewall ruleset got munged when you posted it, the pf table angle brackets are missing in all references to it in the file. Running it will spew an error. Fixed pf. Works for me Ansible freebsd-pf. Hi, thanks for this article. How can I setup my router so that wired and wireless interfaces are on the same network, i. It is important to me because I use raspberry pi with osmc as my media center and it's connected by cable to the AP.

The gateway then tries to figure out who is trying to log in by performing a reverse DNS lookup of The problem is Some will quickly return an error message, in these cases, OpenBSD will assume there is no more information to be gained, and it will quickly give up and just admit the user. In this case you will find yourself waiting for the OpenBSD name resolver to time out, which takes about two minutes before the login will be permitted to continue.

In the case of ftp-proxy, some ftp clients will timeout before the reverse DNS query times out, leading to the impression that ftp-proxy isn't working. This can be quite annoying. Fortunately, it is an easy thing to fix. When chaning network cards need to remember that 1. Need to change pf. I have always enjoyed seeing actuall configuration files so i can see what someone is talking about so here are all the files I usesd.
