A Midsummer Night's storm

Today I stumbled upon a very nasty behavior of glibc - again. On a host

Which has no access to IPv6 at all and no-support module in the kernel, it seems the connect () call fails when there is a AAAA record in place for a remote server.

This means I can not wget to a webpage if AAAA record exists for the page, etc. You will find many solutions on how to 'disable IPv6' - But they all miss the resolver in glibc, the part that is behind the 'gethostbyname' call.

I like to disable DNS queries for IPv6 AAAA completely - and the solution is easy:

# cat / etc / resolv.conf nameserver options no-inet6 ... NameServer ...

Just documenting it here, because the manpage does not document the 'No' feature and searching for this on google was not helpful at all
