fail2web

fail2web is a fail2ban GUI that communicates with a fail2ban instance via fail2rest

fail2ban allows you to administer the following

  • Failregex - Delete and add new failregexes
  • Banned IPs - Ban and Unban IP address
  • Per Jail Config - Configure find time, max retry and usedns per jail, and view the filelist per jail
  • Alerting - Notifications when an IP address is banned and unbanned with a user configurable time span
  • Regex Testing - Testing ignore+fail regexes on your current logs to quickly build and debug regexes

with the following features planned in the future

  • Reporting - Expose the time that an IP address was banned, and show trends via visualizations
  • More Jail Controls - Create new jails and expose more settings for current jails

Installing

###Development

  • Install build requirements
  • Install libraries
    • execute npm install in the root of the fail2web repository
  • Building
    • When writing code run npm run watch this will rebuild web/bundle.js on every change
    • When deploying run npm run build this will build once and exit

###Production There is no production release of fail2web, but I plan to have one soon.

##Deploying and Configuration To run fail2web you should host it via a HTTP server, the following is an example nginx config to do so

server {
    listen       80;
    server_name  YOUR_SERVER_NAME;

    auth_basic "Restricted";
    auth_basic_user_file YOUR_HTPASSWD_FILE;

    location / {
        root FAIL2WEB_WEB_FOLDER;
    }
    location /api/ {
        proxy_pass         http://127.0.0.1:5000/;
        proxy_redirect     off;
    }
}

Fail2web has only one configuration option available via config.json in the root of the web folder. This config option allows you to specify the path to your fail2rest handler. Currently the config.json uses /api/ which is what the above nginx config is also set to do.

Fail2web then has to communicate with a fail2rest instance, details on how to configure fail2rest can be found here

###Security It is very important that you configured fail2rest correctly, a public facing fail2rest server could be very dangerous (someone could add inclusive regexes, remove themselves from the banned IP lists etc..)

Out of the box fail2rest has no authentication, and I have no plans of rolling my own authentication. I have used two different methods for securing my fail2rest instances.

####HTTP Auth In the nginx example above I have enabled HTTP basic auth with the following lines

    auth_basic "Restricted";
    auth_basic_user_file YOUR_HTPASSWD_FILE;

To generate a HTTPASSWD file you can use the htpasswd util distributed with Apache HTTPD and htpasswd -c YOUR_HTPASSWD_FILE USERNAME will create it.

####Serve on loopback only Your other choice would be to serve on the loopback only. You could then use an SSH tunnel as a socks proxy.
