and here is the source code from your example file:

require 'rubygems'

# You can specify other DNS servers easily

    match(/dev.mydomain.org/, IN::ANY) do |match_data, transaction|

        [IN::A, IN::CNAME, IN::MX].each do |resource_class|
            logger.debug "Appending query for #{resource_class}..."
            transaction.append_query!(transaction.name, resource_class)
        end
    end

    # For this exact address record, return an IP address
    match("dev.mydomain.org", IN::A) do |transaction|
        transaction.respond!("10.0.0.80")
    end

    match("80.0.0.10.in-addr.arpa", IN::PTR) do |transaction|
        transaction.respond!(Name.create("dev.mydomain.org."))
    end

    match("dev.mydomain.org", IN::MX) do |transaction|
        transaction.respond!(10, Name.create("mail.mydomain.org."))
    end

    match(/^test([0-9]+).mydomain.org$/, IN::A) do |match_data, transaction|
        offset = match_data[1].to_i

        if offset > 0 && offset < 10
            logger.info "Responding with address #{"10.0.0." + (90 + offset).to_s}..."
            transaction.respond!("10.0.0." + (90 + offset).to_s)

Hi, seems like a bug in EventMachine (eventmachine/eventmachine#176) - can you try updating event machine to 1.0.3?

[hooopo]

yeah. I'll try it.

Have tried EM 1.0.3. However, this issue presence.

[ioquatix]

I will try on my computer, can you tell me what command you use to cause failure? Are you using dig?

[hooopo]

yes.

dig test111.mydomain.org

[ioquatix]

What version of RubyDNS are you using? 0.6.0 had some changes to the rule argument order. Previously it was |match_data, transaction| but now it is |transaction, match_data|.

Where did you get the example code from, what file, and what version of RubyDNS? I'm pretty sure I updated all the examples.

[ioquatix]

Also, dig test1.mydomain.org will return a result as per the logic in the script. dig test111 probably isn't going to work as expected.

[hooopo]

rubydns version 0.5.4
oh! you updated example two days ago. I got the example 3 days ago..

[hooopo]

pry(main)> "test111.mydomain.org" =~ /^test([0-9]+).mydomain.org$/
=> 0

Is your dns match ruler the same as regexp?

[hooopo]

sorry, I missed this logic:

offset = match_data[1].to_i

        if offset > 0 && offset < 10
            logger.info "Responding with address #{"10.0.0." + (90 + offset).to_s}..."
            transaction.respond!("10.0.0." + (90 + offset).to_s)
        else
            logger.info "Address out of range: #{offset}!"
            false
        end

[ioquatix]

Yeah, sorry, it was updated recently which might cause some confusion, note the message in the README file which explains the changes. The changes were made because many times you don't care about match_data, and since it was the first argument you still had to write it down. Now, you can just ignore it on the argument list which is very convenient.

[ioquatix]

If you have any further problems, please open a new ticket :D Thanks for trying out RubyDNS.
