freebsd stable - Dec 2009 - duplicity ftp backup / ncftp no longer working since 8.0-Release

Hi,

since my upgrade to 8.0-RELEASE my backup solution with duplicity is no
longer working because ncftpput fails.

The error message from ncftp 3.2.2_1: Could not read reply from control
connection -- timed out.

S.a. http://www.freebsd.org/cgi/query-pr.cgi?pr=140934

Does anybody know a solution or a workaround?

Thanks,
Manfred

I have seen this with ncftpput as well, but at least in my case, it
was a warning, and not a fatal error.  Check your ftp server to see if
the backup file has indeed been transferred.

I believe that there is something unusual going on with the checking
on select() return in ncftp3.  If you change every instance of
select() result checking in ftp/ncftp3 from "==1" to
">=1" the problem
seems to go away.

result = select(sfd + 1, NULL, SELECT_TYPE_ARG234 &ss, NULL,
SELECT_TYPE_ARG5 &tv);
-if (result == 1) {
+if (result >= 1) {

Good Luck.

The file is getting transferred, but duplicity assumes that it is not
and abends.

I will try this.

OK.   I will try to report it to the upstream (ncftp.com/contact), and
failing that we could always patch as part of the ncftp 3.2.3 update
into freebsd ports, but glad to hear it worked for you.
