I asked ChatGPT to give a step-by-step guide on how to setup a DNS Cache server that can verify DNSSEC on Debian 11, but the response was cut off on Telegram:

ChatGPT, [3/8/2023 10:56 AM] Sure

This is the corresponding log at debug level 2:

Here are the steps to set up a DNS cache server that can verify DNSSEC on Debian 11 using Unbound:

1. Install Unbound by running the following command:

   sudo apt-get update
   sudo apt-get install unbound

2. Configure Unbound as a caching resolver and enable DNSSEC validation by editing the /etc/unbound/unbound.conf configuration file. You can use your favorite text > editor to open the file, for example:

   sudo nano /etc/unbound/unbound.conf

   Then add the following configuration options at the end of the file:

   server:
   # Use root hints for resolving instead of forwarders
   # If you prefer to use forwarders, replace with "forward-zone"
   # and add "forward-addr" lines with the IP addresses of your forwarders
   root-hints: "/etc/unbound/root.hints"
   
   # Enable recursive queries
   do-recursion: yes
   
   # Enable DNSSEC validation
   auto-trust-anchor-file: "/var/lib/unbound/root.key"
   val-clean-additional: yes

3. Download the root key file for DNSSEC validation by running the following command:

   sudo unbound-anchor -a "/var/lib/unbound/root.key"

4. Restart the Unbound service to apply the changes:

   sudo systemctl restart unbound

5. Test the DNS server's DNSSEC validation by querying DNSSEC-signed domains and verifying that the answers contain valid DNSSEC signatures. For example, you can use > the dig command to query the example.com domain and check its DNSSEC status:

   dig +dnssec @127.0.0.1 example.com

That's it! Your DNS cache server is now set up to verify DNSSEC on Debian 11 using Unbound.

Node version is 18.14.2. Bot version is 2.3.2.

A small update: I added if (this.debug >= 2) logWithTime("⚠️ Escaped message:", text); to see what's going on and found that <!----> is sometimes present where newlines are. The exact conditions are unknown since if I restart the bot, it goes away and comes back from time to time.

@memoz Hi! I've created an issue in the telegramifyMarkdown repo. I'll update the package once it gets fixed.
