never-ending loop when trying to resolve a non-ip nameserver in /etc/resolv.conf #179

Open javierwilson opened 2 years ago

javierwilson commented 2 years ago

When dealing with an invalid entry in /etc/resolv.conf (in my case an address ending in comma 8.8.8.8,) in config.rb when parsing /etc/resolv.conf:

  1. IPv4.create(n) fails, then
  2. IPv6.create(n) fails, then
  3. Use Dnsruby to resolve the servers First, try the default resolvers. This of course tries to parse /etc/resolv.conf, going back to 1. creating the loop.

Oops!

Thanks for letting me know about this - I’ll make a fix over the next few days when I have some spare time.

Thanks!

Just to say sorry I haven't had a chance to look at this yet. I don't think this is a common problem, so it's quite low priority for me. If it's causing you pain, please let me know.
