For automaounting, kde 4.5 still uses the deprecated hal, which is
horrible to try to manually configure for such things as the *.fdi files
are XML based so in addition to keeping straight the keys and values, you
have to keep track of the XML formatting. Additionally, as I said, hal is
deprecated and replaced in kde 4.6 with udisks based automounting, so
you'll finally figure it out and get it all working the way you want, only
to have the next update screw it up since it uses a different system, with
its own configuration.
That said, not a lot of people have much experience customizing the new kde
4.6 udisks based system...
Possibly the simplest short-term fix, since you already know how to use
mount at the CLI and aren't afraid to do so, would be to create an
appropriate entry in /etc/fstab, setting the umask=077 mode there. hal
ignores devices with entries in /etc/fstab, considering them reserved, for
the sysadmin to handle, so it won't automount them (at least by default).
That'll mean you'll have to handle mounting manually, but as you already
know how to do that and it solves your ssh problem...
Another alternative, of course, would be to copy the data on the USB that
you need and then format it to a reasonable *ix based fs such as ext4
(probably with journaling turned off for flash disks). Of course that
assumes you don't need to access the filesystem and content from MSWormOS
or the like, but it'd allow proper permissions, etc, and in general should
be more efficient than (V)FAT.
Of course, depending on the size, you could fdisk/gdisk the device as
well, creating several partitions, one that could remain VFAT, another
ext4 or whatever, if that better fits your usage needs, too.
Longer term, presumably with (k)ubuntu 11.4, which will presumably contain
kde 4.6.x, you can look into udisk config and see how that works, but
honestly, I'd not bother with hal at this point unless you /want/ to learn
it now, only to have to relearn a new config style with udisks a few
months from now.
Or, you could of course add the appropriate package repos and/or build 4.6
yourself, and install that, then do the udisks thing, now, but of course
that tends to have other issues since it's newer kde on an otherwise older
platform, which tends to have bugs you won't get if you wait until it's
actually shipped as part of a release, where everything's reasonably well
tested together and should be close to the same age.
