Description Oleg Makarenko 1999-10-26 14:09:11 UTC
Ftp upgrade from wu-ftp-2.6.0-1 server hangs after reading
hdlist. mc-4.5.39-0.91 also hangs after copying file.

wu-ftpd-2.5 works fine and 2.6.0 recompiled with

So ftp upgrade and mc seems to be the "broken clients" that
wu-ftpd-2.6 has workaround for but that workaround
unfortunatly was not compiled into wu-ftpd-2.6.0-1 update.

Comment 1 Gilbert E. Detillieux 1999-10-26 20:39:59 UTC
There are other broken clients out there too.  For example, mirror
2.9, for which the following patch has been provided...


Eventually, all of those packages should be fixed (since they're the
broken ones).  Updating ftpd again, to re-break the protocol, seems
like the wrong way to go, but it may be a reasonable short-term
compromise if a lot of useful clients are broken.

This remedy (defining SUPPORT_BROKEN_CLIENTS) also solved
a similar case opened today by one of our customers, using the
standard ftp client available from the DOS prompt on a Windoze
box. We use wu-ftpd-2.6.0-1.i386.rpm on RH 6.0.

Comment 3 Bernhard Rosenkraenzer 2000-01-18 16:17:59 UTC
We won't compile wu-ftpd with support for broken clients, as it causes
instabilities in the transfers.
See the various wu-ftpd readmes.

Comment 4 Anonymous 2000-01-18 17:20:59 UTC
You are right. But nobody claims you should support broken clients. The point is
that you must support all ftp clients that come with your own product. So you
should either fix all broken clients shipped with RedHat 6.1 and make the update
available *simultaneously* to wu-ftpd update or use SUPPORT_BROKEN_CLIENTS as a
workaround. Otherwise you simply broke the working things instead of improving

For example after wu-ftpd update RH6.1 ftp installation doesn't work anymore and
THAT is the bug. If you don't like SUPPORT_BROKEN_CLIENTS then fix ftp install
(and all other broken ftp clients shipped with RedHat if any).

Best regards,
