On systems running the GENERIC kernel (and thus having IPv6 enabled), two
ports that I know of run into trouble: ncftp3 and dillo. For hosts that
have both IPv4 and IPv6 A[A] records:
$ host ftp.vim.org
ftp.nluug.nl has address 192.87.102.43
ftp.nluug.nl has address 192.87.102.42
ftp.nluug.nl has address 2001:610:1:80aa:192:87:102:42
ftp.nluug.nl has address 2001:610:1:80aa:192:87:102:43
These apps insist on making IPv6 connections. However, the only IPv6
routes I have is for lo0. So I get errors like:
Could not connect to ftp.vim.org: No route to host.
My question is why does this happen? Why isn't the connection IPv4 given
I cannot get there from here [over IPv6]?
thanks,
