Hello, Peter!

But resolv.conf also contains a list of nameservers, and without reading it at
least inet_res:getbyname doesn't work (always returns {error, timeout}):

$ erl -name test
Erlang (BEAM) emulator version 5.4 [source] [hipe] [threads:0]

Eshell V5.4  (abort with ^G)
(test@REDACTED)1> inet_res:getbyname("_xmpp-server._tcp.jabber.ru", srv). 
{ok,{hostent,"_xmpp-server._tcp.jabber.ru",[],srv,1,[{0,0,5269,"jabber.ru"}]}}

$ erl -sname test
Erlang (BEAM) emulator version 5.4 [source] [hipe] [threads:0]

Eshell V5.4  (abort with ^G)
(test@REDACTED)1> inet_res:getbyname("_xmpp-server._tcp.jabber.ru", srv).
{error,timeout}
