Issue #19928 has been updated by kjtsanaktsidis (KJ Tsanaktsidis). Hmm. The resolver is already catching `Errno::EAFNOSUPPORT` for this, but I guess `Errno::EPROTONOSUPPORT` can happen as well (is this a BSD vs linux thing, I wonder?) - see https://github.com/ruby/resolv/blob/b28a2665cd87c4749096ab5201b7d936d4a61d5e.... It seems reasonable to catch both though. I opened https://github.com/ruby/resolv/pull/41 for this. ---------------------------------------- Bug #19928: IPV6 nameserver issues: "Protocol not supported - socket(2) - udp" https://bugs.ruby-lang.org/issues/19928#change-105208 * Author: brendans-bits (Brendan Bits) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.4p223 (2023-03-30 revision 957bb7cb81) [amd64-freebsd13] * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN ---------------------------------------- I get a similar error message to https://bugs.ruby-lang.org/issues/9477 The error message I see: ``` Errno::EPROTONOSUPPORT: Protocol not supported - socket(2) - udp ``` Similarly: ``` $ ruby -rresolv -e 'puts Resolv::DNS.new.getresource("_rubygems._tcp.rubygems.org", Resolv::DNS::Resource::IN::SRV).target' /usr/local/lib/ruby/3.1/resolv.rb:750:in `initialize': Protocol not supported - socket(2) - udp (Errno::EPROTONOSUPPORT) from /usr/local/lib/ruby/3.1/resolv.rb:750:in `new' from /usr/local/lib/ruby/3.1/resolv.rb:750:in `block (2 levels) in lazy_initialize' from /usr/local/lib/ruby/3.1/resolv.rb:740:in `each' from /usr/local/lib/ruby/3.1/resolv.rb:740:in `block in lazy_initialize' from /usr/local/lib/ruby/3.1/resolv.rb:735:in `synchronize' from /usr/local/lib/ruby/3.1/resolv.rb:735:in `lazy_initialize' from /usr/local/lib/ruby/3.1/resolv.rb:771:in `sender' from /usr/local/lib/ruby/3.1/resolv.rb:527:in `block in fetch_resource' from /usr/local/lib/ruby/3.1/resolv.rb:1125:in `block (3 levels) in resolv' from /usr/local/lib/ruby/3.1/resolv.rb:1123:in `each' from /usr/local/lib/ruby/3.1/resolv.rb:1123:in `block (2 levels) in resolv' from /usr/local/lib/ruby/3.1/resolv.rb:1122:in `each' from /usr/local/lib/ruby/3.1/resolv.rb:1122:in `block in resolv' from /usr/local/lib/ruby/3.1/resolv.rb:1120:in `each' from /usr/local/lib/ruby/3.1/resolv.rb:1120:in `resolv' from /usr/local/lib/ruby/3.1/resolv.rb:521:in `fetch_resource' from /usr/local/lib/ruby/3.1/resolv.rb:507:in `each_resource' from /usr/local/lib/ruby/3.1/resolv.rb:488:in `getresource' from -e:1:in `<main>' ``` I am running this in a FreeBSD jail (created by Bastille) that does not have IPV6 connectivity, on a host that does have IPV6 connectivity. Similar to the previous issue, the problem is successfully resolved by commenting out the IPV6 nameserver lines. Longer output for reference: ``` rake aborted!
