Subject: ftape-4.02 on linux-2.2.5 (iomega ditto max drive)
Hi folks!
I've got an Iomega ditto max tape drive which i want to
get running using SuSE Linux 6.x
This drive is known to work somewhat and somehow since
ftape version 4.x. In the related documentation it is
claimed that since linux-2.1.x, ftape 4 is included
in the kernel.
What i found out is, that the ftape version included
in 2.2.5 and 2.2.7 is ftape-3.04 which does not yet
support this tape drive. Having seen this, I tried to
compile the seperate ftape-version 4 using 2.2.5 and
then 2.2.7. This didn't compile because of some kernel
changes (the field timeout has disapeared from struct
task_struct, the functionality has moved to add_timer
and/or schedule_timeout). So I tried to adapt ftape-4.02
to the kernel changes. I reached the point where ftape
compiled, but when I tried to load the modules ftape
hung in the initialization phase waiting for interrupts,
which will be my fault.
I just don't have more time and also not enough experience
with linux kernel programming to get further... :-(
Has anybody out there a solution for this problem, e.g.
a version of ftape-4.02 that works with a kernel 2.2.x?
If so, please be so kind to answer via email.
Thank you in advance and greetings,
Michael

yes (the translations in the xterm resource file)
no (don't bind it to the "exit" string, but to the "quit()" action).

I've been through that whole E control panel many times, and I can't
find any setting that affects this problem. Does anyone know which
setting it is, exactly? Clicking on tasklist items FOCUSES the windows,

Chris,
You are right. What my concern was more towards the swapped out data that
never gets referenced and just stays in the Swap. From your explanation
above, the kernel should release the XFree86 initialization code should
there be of no value to pulling it back into the memory. Would not it make
more sense?

Not really a good idea if, like me, you have two kernels...
One's optimised for pentium, but I'm not moving fully to it yet because it's
ppp is broken. The other is a fully modular 386 compiled kernel with a
working ppp...

Absolutely. I can't remember this economist, who took it into account
in his work as well, but nevertheless it does not change the vulgar
fact of Comparative Advantage law operating. If we _don't_ exploit
it, many people will be practically forced to live and work elsewhere.

I would not want to move out of my country permanently either, but if
the disparities between Europe and US will continue, I'll try to move
to US (though I would not want to move there permanently). I don't
have whole life waiting till Europe reforms itself. Time is running.

IIRC, if you view it with a standard text viewer, you'll see the password

PKZIP isn't very secure.

You are not in the directory with the kernel sources. The reason might
be that you don't have the kernel sources installed.

Agreed, but when you check how many potential buyers there are, it is going to
be the largest internal market. True, politicians are playing all sorts of
games.

All caused by the politicians. I think the internal market might get much
protection from Brussel. You see it already happen. My company is not allowed to
import MS products form the US without permission from MS. Brussel protects MS
and companies like HP, Toshiba and others against this.

I believe you can change how frequently Linux flushes the disk. I think you can
even turn OFF write caching. But the whole thing is a matter of choice. More
frequent flushing yields higher reliability, but poorer performance. I remember
running some old Windows 3.1 machines with SMARTDRV turned off. They were
considered fast machines at the time, but performance was completely
unacceptable. But, we never really had to worry about corrupting the hard
drive....

Agreed. We use lots of NT servers here and they frequently don't survive power
losses very well. The workstations seem to fare better, but I suspect that's
because they aren't under the same load that is seen by the servers. I even know
of a few people in our IS department that insist on just flipping the computer
off. I've warned them several times, but they say that since they've never seen
a problem, they're going to keep on doing it. I guess they'll stop the first
time they lose a full month's worth of work.

Win95 doesn't even have to be shut down unexpectedly to corrupt the hard drive,
so let's leave that one out of the equation. DOS is really good about unexpected
reboots as long as you don't have SMARTDRV running with Write cache enabled.

VMS is terrible about this. That's why one of the companies I worked for had

For what it's worth, we've had several power outages at my house with no UPS.
Nothing nasty happened to the file system at that time. The difference is,
though, I wasn't logged into the computer. Therefore, there was hardly anything
going on to cause corruption.

Sometimes the manual intervention is better. At least you get to make a decision
on what fsck does, rather than letting it guess for you. Maybe deleting that
corrupt file ISN'T what you want because it contains important information, some
of which you could salvage. And having it move the file aside might not work
either, as you might feel the need to use a disk editor to retrieve the
information.

Why? So it can stand idle and empty? Linux is _supposed_ to be a
memory hog in the sense it uses as much of your system's resources as it
can lay it's hands on.
This is a good thing (I'm beginning to understand Nudds' affinity for

There are already a couple utilities that will do this for you. One is
EMACS. If you have a file called foo, and you edit and save it, the new
copy is called foo and the old one is renamed to foo.~1~. If you edit and
save it again, the former foo renamed to foo.~2~ and is replaced by the
edited foo.
Kermit does the same thing with transferred files. If you send a file
called foo to Kermit on UNIX, Windows, etc, and the file already exists,
the existing copy is renamed to foo.~1~ (or foo.~2~, etc, -- the next
unused number).
When you save a file in EMACS, it "purges" excess old versions of the same
file. C-Kermit 7.0:
http://www.columbia.edu/kermit/ck70.html
has a PURGE command that lets you delete old generations, keeping any
desired number of them, for example "purge /keep:3 foo".
In VMS (and in the late TOPS-20), this sort of thing is (was) a built-in
feature of the file system.
