|
|
The gethostbyname4() lookup method is problematic since it fires out both
|
|
the A and AAAA DNS queries in parallel and over the same socket. This
|
|
should work in theory, but it turns out that many cheap DSL modems and
|
|
similar devices have buggy DNS servers - if the AAAA query arrives too
|
|
quickly after the A query, the server will generate only a single reply
|
|
with the A query id but returning an error for the AAAA query; we get
|
|
stuck waiting for the second reply.
|
|
|
|
For gethostbyname4() users affected, disabling IPv6 in the system might
|
|
work around the issue, unfortunately it only helps with applications
|
|
using AI_ADDRCONFIG (e.g. Firefox); some (notably e.g. Pidgin) neglect
|
|
to do that.
|
|
|
|
Real fix should be using separate ports for the A and AAAA queries.
