an arbitrary session expiration time, defined in seconds.development environments to which they need access.For each IP address or IP range, we need to track a few things about the person who is connecting from this IP. In our example, we want to create an access list of some IP addresses to allow them access to a VPN or a hosted application. Fire up a pre-configured Vagrant VM or just install the required modules manually. Use our GitHub repository to follow along with the actual scripts. So, as far as deployments go, you’re not constrained to any one language when you want to read from the database. Many are listed on the GeoIP2 download page. NET, PHP, Java and Python readers in addition to unsupported third party MMDB readers. You’ll need to use Perl to write your own MMDB files, but you can read the files with the officially supported. The code samples I include here use the Perl MMDB database writer and the Perl MMDB database reader. This kind of database could be used when allowing access to a VPN or a hosted application. In this blog post, we’ll create an MMDB file which contains an access list of IP addresses. MMDB comes with supported readers in many languages. If you use a GeoIP database, you’re probably familiar with MaxMind’s MMDB format.Īt MaxMind, we created the MMDB format because we needed a format that was very fast and highly portable. September 2020 Update : We’ve got a new post that deals with writing MMDB files using the Go programming language.
