Fairly likely not, unless you are exceedingly lucky. When a file is
"overwritten," this tends to result in the formerly occupied blocks
getting tossed onto some form of "free list," eventually to be
reclaimed and used for some other purpose.
If it has been a while since the "overwriting," and you have made
quite a lot of changes to files on the filesystem involved, then it is
fairly likely that the old version has been overwritten.
If that be the case, recovery methods likely involve fairly ridiculous
extremes like hiring in security engineers to use things like electron
microscopes to pull signals off the hard drive. Down that road lies
costs of thousands of dollars...
More likely, you've lost the data, with no practical recourse. This
is a painful lesson that demonstrates the _necessity_ of doing regular
backups of important data.
There's a sad story (perhaps, but probably not, apocryphal) of a
graduate student that was nearing completion on a Ph.D thesis; shortly
before submission, there was a fire that burned his apartment, along
with the text of the thesis, as well as all his notes. There was
nothing to be done, as his thesis efforts became _ashes_. He could
not muster the funds or the emotional effort to restart the process,
and had to give up on the degree.
I had a disk crash, destroying the whole text, at about that same
point in my M.Sc, just as I was finalizing things. Fortunately, I was
_already_ paranoid, and had enough backups stashed away in different
cities for it to be a non-issue. [I lost more time out of the 6 days
it took to ship in a new drive than from anything else.]
By the way, your question doesn't seem likely to have much of anything
to do with Linux, as Lotus 123 is not an application known for running
on Linux...

It is known that gcc-2.95.2 doesn't build right on glibc-2.2 systems.
I'm not sure whether you are running into this particular problem,
but you could try
(1) applying the patch at
http://clisp.cons.org/~haible/gcc-glibc-2.2-compat.diff
or
(2) trying gcc-2.95.3.test*, which is being prepared for release soon; see
http://gcc.gnu.org/ml/gcc/2001-03/msg00387.html

Subject: can a serial connection work when keyboard/monitor doesn't?
Date: Thu, 15 Mar 2001 04:31:27 GMT
I work for a fairly large sized Website provider, and we also have
dedicated Linux servers. One of my jobs is rebooting dedicated servers
that have crashed for one reason or the other. 99% of the time I have
to do a hard reboot. Is there any way to avoid this without having
someone on the server moitoring processes 24 hours a day?
When I go to reboot the machine, I connect the monitor and keyboard
directly to the server, and usually I don't get anything, just a blank
screen and the keyboard doesn't do anything. I was wondering if either
a direct serial connection, or a connection via a console server would
at least allow me to soft reboot the machine, or if there is any other
way to reboot the machine without hitting reset ie a KVM switch, etc.

This is related to my previous post. Again, I work for a medium sized
webhosting provider who also host dedicated Linux servers. I was
wondering if anyone could recommend some software or scripts that
would keep a Linux server from freezing up because of runnaway
processes, etc, or at least lessen the frequency. Or even if there was
a way to monitor the processes on a server, and make the computer
automatically reboot before it crashed.

Doesn't it just mean that the corresponding "Releases" file couldn't
be found? (The files downloaded by potato's "apt-get update" go in
/var/state/apt/lists.) There are several (seven, today) machines
serving as http.us.debian.org, and sometimes a few seem rather flaky.
(P.S. Is there a reason for using "potato" rather than "stable"?
Are you skipping the security.debian.org stable/updates deliberately?)

You may want to look at the manual page for your favorite window
manager; WMs often provide a mechanism for this.
For instance, I usually run WindowMaker, and it provides a
"point'n'click" way of requesting that apps run at start time.

Has anyone done any investigation of this? Linux machines running the
stable kernel Just Shouldn't Die so long as the hardware is OK.
>Is there any way to avoid this without having someone on the server

In the kernel configuration menu, you will see options for "watchdog"
hardware and a "software watchdog". Check these out. Hardware watchdog
cards may be a significant expense if you have lots of machines to
outfit. The software watchdog will not help you if the kernel's memory
space is being corrupted somehow.

Not even Alt-SysRq-S, Alt-SysRq-U, Alt-SysRq-B ? (This assumes x86
hardware; the "magic key" sequence is different for other architectures)

I assume you can't ssh into the machine, then. A direct serial
connection might work, but if the machine is so hosed that Alt-SysRq
doesn't do anything, I wouldn't hold out too much hope. Please clarify
what you mean by the KVM comment; a KVM is not magic, it's just a way of
having many machines sharing one keyboard/monitor/mouse. A KVM can help
you avoid the problems associated with hot-plugging PS2 mice/keyboards
into cheap x86 hardware, but that's about it.

When using Junkbuster, website logins appear not to work.
For example, when I log into Slashdot, it acts as if I never logged in at
all. None of my settings are recognized, and my "preferences" options
are not displayed next to my user name.
As soon as I remove junkbuster from proxy settings, it works.
Anyone know what's going on?

There are usually equivalents in most WMs - You can also put a line to
call it from one of your login scripts (~/.profile or whatever), but
keep in mind that it will try to launch _every_ time you login, whether
locally or via telnet session, etc.

Don't know what you expect to learn from an OS internals book when

My favorite so far is "UNIX Internals : The new frontiers" by Uresh Vahalia.
Well written, detailed, covers many varieties of UNIX, and branches off to Mach
and NT a bit for comparison.
Not bad, though somewhat uneven to my mind, is "The Design and Implementation
of the 4.4BSD Operating System", by Marshall Kirk McKusick, Keith Bostic,
Michael J. Karels, and John S. Quarterman. This one has some interesting detail
on the TCP/IP implementation in BSD.

There is "watchdog" that basically poll the system each a minute or so
and (if it does not respond), is able to reboot the machine.
