Try this: gem install net-dns

Hi Andreas, The installation was successfull:

C:\Users\ae90693>gem install net-dns Successfully installed net-dns-0.8.0 Parsing documentation for net-dns-0.8.0 Done installing documentation for net-dns after 2 seconds 1 gem installed

But I still receive this error:

C:\Users\ae90693>hostmap -t 10.79.225.1 hostmap 0.3 codename development Coded by Alessandro jekil Tanasi [email protected]

I did never put “2irg.local” on some files… I only added my DNS to “hostmap.conf” file:

DNS servers

DNS server used for the discovery (instead of defaults). Provide a comma separated list.

Example: 192.168.0.1, 192.168.0.2

dns: 10.79.225.1, 10.79.186.136

Can you help me with this issue? Thank you very much!

Francesco

Sorry, can't help you with that. I'm not affiliated with the hostmap project. I just stumbled upon your comment regarding net/dns by coincidence. Perhaps @jekil can help.
