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. + +-= END original header =- + +diff -durN glibc-2_9.orig/resolv/Versions glibc-2_9/resolv/Versions +--- glibc-2_9.orig/resolv/Versions 2008-08-01 19:15:34.000000000 +0200 ++++ glibc-2_9/resolv/Versions 2009-02-02 22:00:46.000000000 +0100 +@@ -102,7 +102,7 @@ + _nss_dns_gethostbyname_r; _nss_dns_getnetbyaddr_r; + _nss_dns_getnetbyname_r; _nss_dns_getcanonname_r; + _nss_dns_gethostbyaddr2_r; +- _nss_dns_gethostbyname4_r; ++# _nss_dns_gethostbyname4_r; + } + } + |
