I am creating an altcoin, following a tutorial. The tutor skipped explaining setting up the DNS seeder.

How can I implement this code https://github.com/sipa/bitcoin-seeder ? Currently when I run ./mycoind (on my local machine) I get connection refused when trying to connect to the seeder defined in strMainNetDNSSeed

When I run ./dnsseed (on my vps) it does not run on port 8333 (actually 9333, I am using https://github.com/pooler/litecoin-seeder/ , a fork of the bitcoin seeder). Can anyone help?

There are many steps to setting up a DNS seed, so it is next to impossible to determine why your attempt failed without having more knowledge of your setup.

But if you are trying to set up a DNS seed for an alt coin, then I would strongly suggest you use the generic-seeder to prevent having to muck around in the source code.

The generic-seeder is a clone of the original bitcoin-seeder app that aims to make it easy to run a seeder for virtually any blockchain network. The bitcoin-seeder was developed specifically for the bitcoin network only, and configuring it to work with a different blockchain network can be time-consuming and tedious at best. The generic-seeder overcomes this limitation by utilizing a configuration file that holds the data used to connect to a given blockchain, without having to edit the source code, and adds new features and a full setup tutorial as well.

DNS seeder runs on port 53 It crawls on p2p port of your coind which in your case is 9333. Click this link for further instruction.
