RE: [suse-security] wu-ftpd data channel opening errors
I'm using xinetd instead of inetd. After issuing lsof this is what I get> xinetd 11282 root 3u IPv6 10917544 TCP *:ftp (LISTEN) ftpd uses IPv6 and wu-ftpd documentation states no IPv6 is currently supported. How can I change this from IPv6 to IPv4? I guess it's the matter of xinetd.

Are you sure you are only running one ftp daemon ? I somehow get the feeling that you might have another ftpd running ("port theft"). Check your /etc/inetd.conf to make sure there is only one line enabled for "wu.ftpd" and others are disabled (like in.ftpd, proftpd, ...) You can try "ps ax | grep ftpd" and "lsof -i tcp" to see whether there's a programme listening on port 21.

Now I'm replying to myself :) when I connect to wu-ftpd via inetd everything is just fine. xinetd seems to make problems. Ideas?

We used to run into these problems on ftp.suse.com some months ago, when we waded through the packages to check for ipv6 comliance. xinetd does not have a runtime switch to turn off ipv6 support, there is only the possibility to recompile the package with ipv6 disabled. Install the source rpm and remove the line containing "--with-inet6" from the specfile, then recompile the package using the command rpm -ba xinetd.spec. The author of xinetd did not want to have the switch, so we did not implement one as well.

Problem solved! This is how it ended, in case anyone else runs into the same problem: I have downloaded latest version of xinetd package from www.xinetd.org and compiled it using --without-inet6 (among other switches). After that I set up my box to use that xinetd. Everything is just fine now. Thank you all, guys!
