+OK, I'll try that too.  As for the reason, I updated CentOS 5 on the
+server to CentOS 6, and about the same time updated my Fedora
+installations.  This is some time back, so my memory is a little hazy
+- - I think the change that broke the mounts was at the server end, but
+I'm not sure about that.  Anyway, I did lots of googling to find help,
+and eventually got them to work in this way.  Of course the pages I
+read could have been way out of date - sadly few pages have a date on
+them, so it's hard to know how old and how relevant they are.
+
+(My experience on the subject of non-dated pages are why I persuaded
+the KDE sysadmins to have updated information in page footers on
+UserBase.  At least you can see if a page gets out of date.)
