It seems that for a while, ftp.infradead.org has been accessible only over IPv6. This is now resolved, and those of you without IPv6 connectivity should now be able to reach it again. My apologies for the inconvenience. For those who care, the problem was with the Fedora vsftpd package. A while ago, it had a bug that it did not support IPv6 at all by default, as all Fedora packages should. Instead, it only listened on Legacy IP. By enabling a 'listen_ipv6' option instead of 'listen_ipv4', it could be made to work correctly for both protocols. The bug (#450853) requesting this change in the default configuration has remained unfixed since 2008, unfortunately. The default configuration was not changed, and no alternative fix was put in place either. So my machines were running with a non-standard configuration, just to make things work as they should have done out of the box. Even more unfortunately, a recent change in the Fedora package made the 'listen_ipv6' option listen *only* on IPv6, and not accept Legacy IP connections any more. This was done to make the behaviour match the documentation (bug #592850). (Personally, I'd rather have fixed the documentation to match the code.) So the FTP server stopped accepting connections from Luddites, and I didn't notice. -- dwmw2
