The patch sets socket option to listen on IPv6 only
Red Hat Enterprise Linux Beta 2 is now available and should resolve the problem described in this bug report. This report is therefore being closed with a resolution of CURRENTRELEASE. You may reopen this bug report if the solution does not work for you. The way I see it, this was a *documentation* bug. The documentation lied, and we should have changed the documentation to tell the truth. Changing the code to match the documentation has *broken* vsftpd, which no longer listens for Legacy IP connections and IPv6 at the same time. See related bug 450853. We should fix the documentation so that it makes it explicit that 'listen_ipv6=YES' also listens on Legacy IP (which fixes this bug). And we should change the default vsftpd.conf to make that the default (which fixes bug 450853). I completely agree with David. I need to serve ftp over both IPv4 and IPv6 and I currently see no other way doing that than running two separate vsftpd instances - which is lame and completely wrong! Bug 839257 open to revert that change. |
