[CentOS-mirror] ftp.wrz.de IPv6

Hello Anssi,

thanks for the hint. I created a seperate process for that. As I found out
multiple "Bind"-statements in the config-file for pure-ftpd are not
possible.

It works now.

Best Regards
Christian

DNS-entry was up there was traffic via v6 instantly.

Great, it's nice to have more IPv6-capable mirrors. I have now added
2003:d1:3012::400/126 to the ACL so you should now be able to rsync over
IPv6.

There is only a slight problem with FTP over IPv6:

$ telnet ftp.wrz.de ftp
Trying 2003:d1:3012::400...
telnet: connect to address 2003:d1:3012::400: Connection refused Trying
217.243.224.144...
Connected to ftp.wrz.de.
Escape character is '^]'.
220---------- Welcome to Pure-FTPd [privsep] [TLS] ---------- 220-You are
user number 1 of 250 allowed.
220-Local time is now 12:40. Server port: 21.

220 You will be disconnected after 15 minutes of inactivity.
quit
221-Goodbye. You uploaded 0 and downloaded 0 kbytes.
221 Logout.
Connection closed by foreign host.

I wonder if the IPv6 part could be fixed? It's currently showing up as a
failure on http://miuku.net/ipv6reach/ where I keep statistics of
IPv6-capable mirrors. An alternative would be to remove the FTP URL from our
mirror database. I think we already have a sufficient number of FTP mirrors
to serve the needs of those users who prefer to get their files over FTP.

Thanks!
