Mutt & Hebrew

[Oren Held]

Hi Guys, and Chag Same'ach,

Haven't posted here in a while... Good to be back :)

I've recently switched to mutt, and still got some bidi issues unresolved.
As I was sure this subject came up here previously, I googled a bit, and found 
this thread http://mirror.hamakor.org.il/archives/linux-il/10-2004/12174.html.

In short, it suggests using 'set display_filter=bidiv' for viewing Hebrew. It 
works smoothly.

Still, 7 years after, I bet that some things have changed. I summed up my 
current questions on working with mutt and Hebrew:

Reading mail

1. bidiv solution seems cool, but isn't it time for real integration of fribidi 
in mutt? Did anybody recently try and failed? Is the author known for his 
anti-bidi beliefs?

Composing (i.e. bidi support in the editor)
---
2. Any vim solution?
3. Any recommended bidi-aware editor that plays nice with mutt?
4. For now I'm manually adding RLE special character before each 
Hebrew-containing line and it does the trick, partially. RLM didn't seem to 
work. Is it a reasonable thing to do? A smart trick to automate this in vim?

I was wondering the same once, and wrote this little post:
http://www.held.org.il/blog/?p=79

Note the references which I based this on.

In short: it's not easy to measure, but the penalty seems to be quite 
insignificant. Still, using a 64 bit kernel (even on 32 bit os!) removes the 
need for PAE.

Re: DTT

[Oren Held]

The transmissions have already began a few weeks ago or even earlier, and the 
hardware is already available in some shops.

Yet, as far as I know, the official start date is August 1st, and until then, 
problems (e.g., bad reception) may occur.

Barak 013. Octal 11 == Decimal 13 :)

Their sudden firewall change also stopped the mail activity for a non-profit
organization I'm volunteering at, for a whole day. This is not the way they 
should've done this, I bet hundreds of customers have suffered (or still 
suffer) from this, wasting hours in analyzing the problem.

As a user, I don't really care if the JS code is "not too brilliant" as long 
as the site is usable from the major browsers. I think that we (as Linux

Wrong, instead of the "@" should be szabgab.com and not mail.szabgab.com - 
because he wants u...@szabgab.com mail addresses.

Indeed the @ looks suspicious, unless it says "use the previously used domain" 
(whitespace, and not "@", in bind's zone files), it might be the cause of the 
problem.

They have no email address. I snail-mailed them, to the address mentioned in

Maybe it might be good that you provide them that URL in your letter, to 
remind them about their firefox-compatibility announcement.

Things are getting better indeed, but you are exaggerating:
1. Orange sites are far from working on FF, although they're getting closer 
(can't send SMS, can't read "perut sichot" on orange-bill). See what they 
wrote me a few weeks ago: http://israeliweb.blogli.co.il/archives/19
Of course, that's unless something was changed very recently and I'm not up-

2. Clalit doesn't work, it's been discussed here on the list only a few days 
ago. Even the "Contact Us" link on the login page fails. (https://e-

I've been purchasing stuff from there using Firefox for years.
They had few firefox-incompatibilities and sent the user's password in

This doesn't make much sense; somehow the openoffice process probably cannot 
write files to these directories.

I'd be:
1. trying to mimic openoffice by simply "echo"ing into a file on the same

2. strace -e file -f -o /tmp/ooo.strace oowriter
then inspect /tmp/ooo.strace for these file-writing errors.

 - Use the RAZOR2 filter, PYZOR, DCC
 - Use bayes filter ("teach" sa using sa-learn)

Maybe you already checked that, but just in case you didn't:
*BEFORE* running ntpd, the clock should be more-or-less sync'd (I think - up 
to 2min drift). If drift is too high, ntpd won't even try to fix the clock.

That's why most distros run ntpdate on boot before starting ntpd.

Also paste the ntpq -p output as was already suggested here.

It's not a direct answer to your question, but:
Asus Eee uses an SSD drive [http://en.wikipedia.org/wiki/ASUS_Eee_PC#Storage], 
and also ships with Linux 
[http://en.wikipedia.org/wiki/ASUS_Eee_PC#Software].

Also, some googling shows that Eee ships with ext3 but people recommend ext2

Re: 64-bit linux

[Oren Held]

x86_64 (recognized by 'lm' flag in /proc/cpuinfo) is fully backward compatible 
(16/32 bit).

Of course, a 32bit binary would require 32bit libraries and vice versa (so you 
cannot use 32bit plugins in 64bit firefox without a hack, for example).

Even though x86_64 is mature enough to have all foss in 64bit form, x86_64 
distributions (at least fedora/redhat) still supply popular libraries (i.e. 
libc) in 32bit form.

I didn't understand your "Anything you can recommend?" question.

SNMP: GET/SET vs. TRAP

[Oren Held]

Hi,

net-snmp's GET/SET mechanism looks completely separated from the TRAP 
mechanism, which I find quite bizarre.

NET-SNMP claims to be easily extensible with Perl 
(http://net-snmp.sourceforge.net/wiki/index.php/Tut:Extending_snmpd_using_perl)
However, this extension doesn't know what a TRAP is, only handles GET/SET 
commands.

It seems as if I have two options:
A. Write a completely separate Perl daemon that sends traps using Net::SNMP

Re: choice of groupware, choice of provisioning server?

Why would they insist of the mail service would be local? It'll raise many new 
concerns: availability, backups, data corruptions..

If it's just a need for shared calendar and central mail storage, I'd be using 
Google for domains. Should be free of charge for small companies.

IMAP/POP3 is supported and there's also a new outlook-calendar-sync software; 
but I prefer to use the GUI for calendar stuff.

Why would it use @gmail.com? I was talking about Google for domains - or maybe

Re: installing CentOS/RHEL without CD using PXE?

[Oren Held]

CentOS/RHEL has the 'kickstart' over network mechanism for about a decade :)

This is a big question, so in general:
1. The DVD contents should be available for reading on an NFS share.
2. TFTP server should supply PXE (see pxelinux), which would lead to the 
correct kernel + initrd (also on the tftp), with kernel parameters "ks" to 
point on your "ks.cfg".
3. DHCP would give the server its IP and the path to the TFTP PXE boot. 
("next-server" dhcp parameter).

I'm sure there's plenty of docs out there about ks..

Re: RPM erasing old packages?

[Oren Held]

A specific file can't belong to more than one package, thus removing an 
unneeded package won't ruin another package's files.
(Unless it was really badly packaged, that rarely happens on the popular 
distros, I guess)

Btw I prefer 'yum remove' and 'yum localinstall' over 'rpm -e' and 'rpm -i' 
(respectively), cuz it's also dependency-aware.

First, kudos for using vim for mails. (Real men use 'ed' =) )

Maybe I was unclear: I wasn't talking about using Logical Hebrew - this I take 
for granted.. I was talking about 'align to the right' and putting the text 
in 'RTL mode', so that mixed Hebrew lines with few English words inside  
would be rendered correctly.

Re: Large scale DNS

Re: Large scale DNS

[Oren Held]

Maybe you should read about Dynamic DNS: it's a protocol extension (bind & MS 
DNS support it for years).
When enabled, bind actually uses journal (.jnl) files for each zone, and 
synchronises the text files only when requested to (i.e. when doing service 
named stop). In this mode you shouldn't edit the text files manually when 
bind is alive!

Dynamic DNS lets you make changes live, forgetting that these text files 
exist. It's simply a protocol extension which allows sending updates (i.e. 
add this record, remove that, etc).

'nsupdate' is bind's not-too-friendly tool for doing these updates,
Perl's Net::DNS allows you to write your customised stuff. I once wrote 
http://hostupd.sf.net to ease this task, although keep in mind it's not 
maintained anymore.

I don't see why you dislike text files so much. This simplicity has many 
advantages. As I see it, the big disadvantages of dns-zones-as-text-files are 
in the EDITING process (multiple edits at once, locking, mistakes which ruin 
the whole zone). These disadvantages are solved by using Dynamic DNS. As for 
storage in text files, sounds cool to me, even for big zones.

1. I think you should be using an LDAP backend to samba. This way Unices would 
auth against LDAP, and windowses against samba (but LDAP DB). I guess samba 
has more backends (mysql maybe?), but LDAP fits best..
2. PDC/BDC setup would probably miss many features (still it's 90s 
technology); Samba 4 should be able to mimic Win2k DC, but it's alpha.
3. I indeed never heard of someone using samba as a DC, although I tend to 
trust the samba guys.. they do good job :)  
4. Have you considered winbind? Either against samba, or actually reinstalling 
a win2k3 DC, while unices authenticate using winbind?

[SOLVED] Recommended filesystem for 6TB storage

[Oren Held]

[... Once upon a time I asked about Linux support of >2TB filesystems ...]

Okay, task is over and we have a 2.5TB ext3 filesystem (eventually not 6TB), 
it looks stable also.

Here are the findings:
1. For >2TB, one must use a "gpt" type partition table and not the default, 
msdos one. Same goes for MS-Windows, if I got it right.
1.1 fdisk doesn't support gpt, we used parted.
1.2 grub doesn't seem to either support gpt or such huge disk/partition. We 
could afford booting from another, small disk (/boot comes back to 
live? :) ), so that did it.. So we didn't research the grub thing too deep.

2. At the beginning we used an msdos partition for the big disk. It didn't 
give errors immediately! only when accessing the >2TB blocks problem occurred 
(i.e. when running fsck, or after few days of writing..).

3. CentOS5 (and thus RHEL5) partitioning config tool ("disk druid", I think?) 
doesn't handle big disks/partition automatically: it created msdos partition 
table.

I'm talking about a system which puts many many 1MB files, spreaded over quite 
a deep directory hierarchy - so directories don't have a huge number of 
files.

It's a proprietary software (yes yes too bad =) ) written in the company I 
work for (videocells.com), the product does heavy writing-new-files (in 
parallel) and deleting-old-files, mostly.
I guess it's not really random access but not really sequential access either.

Quite a tough question to answer in theory, no? I'd better do benchmarks when 
we get the hardware..

Recommended filesystem for 6TB storage

[Oren Held]

Hi,

As far as I understand, ext3 on RHEL5 should support a single filesystem of 
8TB or 16TB.. (http://www.centos.org/product.html)

Still, I wonder if it's smart to create a 6TB ext3 file system.
In theory, filesystem size won't affect stability or performance (except for 
fsck speed I guess). 
But in practice? Anybody got experience with it?

I like ext3 for its stability, nativity and popularity; do you think that I 
should still use something else for such huge disks?

Thanks!

Re: OT: Translate Gibberish to Hebrew

[Oren Held]

Hi,

I'm not 100% familiar with all the tools, but this sounds like something that 
fribidi + iconv already do.. What am I missing?

Or is it the converse of what fribidi does (visual-to-logical)?

Re: Second opinion: oom-killer

[Oren Held]

I have no direct answer to your question. Oom-killer should be triggered in a 
memory emergency, and not when there's enough free memory space.

Some notes though:

A. oom killer doesn't randomly choose a process to kill..  I described the 
algorithm for choosing a candidate for killing in: 
http://www.held.org.il/blog/?p=18 (I *might* have missed something there, 
don't trust it 100%).

B. I can't see why disabling the swap would help to AVOID oomkiller? Swap 
should ENLARGE the available memory space; disabling swap might cause 
triggering oomkiller more frequently. Maybe I misunderstood what you meant.

Re: Linux memory monitoring compared to MS-Windows

[Oren Held]

There's something in your question I don't understand:
If a process has 1gb in virtual memory, of which 500mb in physical,
then this means that it has 500mb in swap. Or in other words: 500mb that the 
process wanted in physical but couldn't. (isn't that what you asked to know)

Obviously I'm missing something here.

Anyway, few notes:
 - MM starts swapping *EVEN BEFORE* all processes hog the whole physical 
memory. That's because the kernel wants to leave some memory space for 
buffers/cache. So you may find yourself swapping idle pages while 
theoretically some physical memory might be freed. This behavior tunable 
via /proc/sys/vm/swappiness
- "free" command has an interesting 2nd line, which shows the net memory usage 
(i.e. without buffers/cache)
- The amazing "top" command can add a swap column; press "O", then "p" and 
enter. (If 'top' can do it, the per-process swap-vs.-physical data can 
probably be fetched from /proc/ some way, I don't know how, though)

Re: Hebrew in KDE?

- As Ilya said, let her try to read the text in some native KDE app, such as 
kwrite/kedit.
- Make sure this text she tries to read is UTF-8 and not iso8859-8 (of course 
if it's required there's a way she could also view that, but why live in the 
80s..).
- Make sure she has 'UTF-8' enabled while typing 'locale' in an xterm. if not, 
export LC_ALL=en_US.utf8, LANG=en_US.utf8 or something similar.

Re: System resource monitoring and reporting utility ?

A friend of mine (Amnon) found Munin (http://munin.projects.linpro.no/), which 
is a great system resource grapher tool which has plugins for almost 
everything from swap, ntp time drifts, disk temperature - to mysql queries 
per second.

However, it draws graphs, I'm not sure it can send alerts. You can set limits 
(like highest cpu temperature or free disk space) which tag the whole node 
as "red", maybe it's even capable of notifying.. worth a check I guess.

Re: GPL Issue

[Oren Held]

No. I just wonder who's salary is actually based on his GPL code work.

I don't argue the GNU ideology now, I just believe that PRACTICALLY
there are no "software houses" (or individual programmers) in Israel
which produce GPL software as their main business, and which survive
and succeed for more than 5 years.

This reason or another, I'm just saying that it doesn't work here
as a salary-source. In Europe & USA there are few cool
GPL-code-based companies like TrollTech, MySQL.  (I don't refer to RH
& SuSE as GPL-code-writers as main business)

An Israeli example for a GPL-related-software-company that I know is
Zend ("The PHP Company").
Zend produces proprietary software such as various PHP-helper-tools -
as their main business.

Ori,

This is your prerogative. I would like to point out that Amos is
clearly not trying to bypass GPL and is in fact acting responsibly 
trying to resolve the issue as soon as it was discovered. They are
trying to maintain what they perceive as commercial advantage by
perfectly legal means, as far as I can judge.

If you are a current client of his company, and if you got their 
proprietary software that links to libipq, I suppose you can demand
that they release their code to you under a GPL-compatible license
(Shlomi is right), sue for it, etc. If you are a shareholder, then you
may have an issue with the company not exercising due diligence and 
catching the problem earlier.

Amos,

I personally appreciate that you (and I hope the decision-makers in
your company) are feeling uncomfortable. I don't think you should feel
like criminals because you want to keep your code legally 
proprietary. I think you have asked the right question and that should
not make you feel uncomfortable. You real problem is lack of due
diligence in the past. (Well, if a customer sues you to release the
code then it will be a real problem, too.) 

I think you need to a) fix the problem as quickly as possible, and b)
apply due diligence in the future.

Re: Hacked server

I disagree, Debian Unstable (Sid) is an ever-updating, bleeding-edge
distro: *tends to bring the latest version of each software*, while
Fedora doesn't.

For example, FC6 has Firefox 1.5, and 2.0 will never be there, only in
FC7.

Debian Testing is the next Debian Stable, like FC is the next RHEL.

However, I'd be trying to eliminate the less-uber-cool-hacker possibilities:
a. Bad local user (Bad user! spank him..)
b. SSH remote login using a weak password which was just guessed 
("test123". Bad user again!).


Also try to check for root kits...

Re: Performance monitoring for selected process

[Oren Held]

Maybe it's too trivial,
but try to check the CPU Time on the moments of slowliness, so you can tell:
- If the process' CPU Time progressing faster in moments of slowliness 
(High cpu load)
- If there's hardly any progress in CPU Time (process is waiting for IO 
or some other resource)
Also I tried to see what /proc/pid/stats give, nothing amazing but maybe 
it helps.

Both. The application in question is developed in-house. Aside from
profiling each module I would like to know why the service "chocks"
after calling it for X concurrent sessions. I'm looking for a tool
that could show, in real time, why the service is busy: is it cpu / io
or memory (causing kernel to swap) intensive. I would have used the
term "bottle neck" to describe what I'm looking to solve, it's just
that it's possible that it's not a "bottle neck" but a simple bug.

Thank you for helping,

Subject: Performance monitoring for selected process

Hi,

Except from "stracing -f" executables is there some way I can monitor
the process for performance? I would like to debug process delayed
response activity and need to know when it's doing heavy IO / when
it's CPU intensive and when it's all too busy waiting for IRQ.

A graphical display would be preferred, textual will do as well 
obviously.


For general system statistics, I've tried the following :
1. sysstat + kSar
2. gnome-system-monitor
3. ksysguard
4. ntop

All work great but are too general for my needs, I'm looking for tools
that could display single process statistics.


Thanks,
Maxim.

Re: Enabling powersave for an lcd screen

I hope I'm not mistaken, but I think you don't need acpi/apm support for 
power save modes of monitors.

Try "xset dpms force off" in X, and see if it works.

xset +dpms should turn on dpms support for current X session.
Enabling dpms & setting timeouts can be done either from xorg.conf 
(search for 'offtime' option) or from kde/gnome gui configuration tools.

Re: Strange name for network interface (Debian 2.6.18-7)

I tend to believe that on single user mode you'll see only the regular

Try to analyze your startup scripts and see which one does that.

At the very least, it could use integration with readline, but ideally

Hola,

I have a couple of DNS servers, in various master-slave relations,
supporting dynamic DNS updates with DNS SEC -- the whole shebang --
powered by BIND servers. Recently when I enabled dynamic DNS updates
for a whole lot of zones (to facilitate a failover mechanism), I found
out I can no longer edit the zone files directly (change zone file ->
rndc reload zone) and must instead do all my changes through Dynamic
DNS (e.g. with 'nsupdate').

Does anyone either:
1. Know of a DNS management tool which uses dynamic DNS updates (IXFR)
to manage zones remotely? 'nsupdate' is hard to use, lacking even the
basic convenience of autocompletion.
2. Know of a different DNS server which works with an LDAP backend and
has a UI tool which can manage it?
3. Has any other suggestion which offers decent UI?

Ideally, it'll be something as good as Microsoft's management console
for their DNS server -- exposing the records graphically and offering
secure remote management.

P.S. Anyway, editing zone files manually was getting error-prone. Most
of the times, editing such structured data with a text editor is a
recipe for syntax errors.

4-way Opteron, 4G RAM, 70G SAS HDD, RHEL AS 4U3, Sun Grid Engine
agents (SGE) v6u7, NIS.
Periodically some of the systems exibit high load average while idling
for no obvious reason. Rebooting solves the problem, but after some
time the symptom returns. Typically the load average reaches 3 and
wouldn't go beyond that. How would you approach such a problem?

One such system shows:

Re: How to meter disk I/O ?

iostat -m 1  would give you nice output about the read/written 
in mb per sec, since the last refresh.


first line is the average since last boot.

procfs backwards compatibility

[Oren Held]

Hi,

I've got an old software (LSF v4.1) which doesn't seem to be kernel 2.6 
friendly:

It dies with SIGSEGV while trying to find the "page" line in /proc/stat,
which exists no more in kernel 2.6.

It works very well on 2.4, and unfortunately I cannot upgrade the LSF 
version (not free software..)


I believe this incompatibility issue comes up with other pieces of code 
as well.

Any more-or-less standard way to put procfs into 2.4-compatibility mode,
or another creative idea?

(Hacking procfs code in the kernel will probably do no good..)

Thanks in advance!

Quota per directory

[Oren Held]

Hi,

We're trying to set quota per directory in my organization.
We use Linux & Solaris, and the builtin-kernel quota feature is only per
file owner or amount of inodes, afaik.

Problem is, that some directories are shared for many people
(i.e. /data/projects/webapp) with different UIDs and GIDs, though I
still want to be able to limit the 'webapp' directory to a maximal value
of 1GB.

Anybody knows a free or commercial tool with the above feature, or a
simple way to implement it?

(We use Veritas Filesystem over NFS, btw)

Many thanks!

OT: ISPs blocking ESP?

[Oren Held]

Hi,

I'm trying to initiate a VPN connection over the net with no success.
Sniffing the interface shows that the VPN client is using the ESP
protocol (Layer _4_ protocol #50, Encapsulated Security Payload), and I
can see only outgoing packets and NO INCOMING ones.

Looks like the ISP blocks the ESP protocol (maybe it accepts only
tcp/udp/icmp and blocks everything else?). The machine uses the
[EMAIL PROTECTED] adsl accounts and behaves the same in most ISPs.

Do you think it's indeed an ISP filter, the guest account's fault, or do
you see other reason for this to happen?
Any experiences with the ESP protocol?

Thanks!
And Sorry for the OT, this is my first one :)
I just see no other israeli ML to send it to..

People don't write code so it'll work only in the future.
People write code in order to give solutions for your current needs.

Look at the wanted section in the newspaper. Many mainframe programmers
are wanted. By your attitude, nobody would need Mainframe programmers in
the 21th Century.

Currently Debian's default is non-unicode and most people don't use
unicode filenames. Yes, it might be (or might not be) different in 2006,
but even then a minority would still use non-unicode filenames, and
adding a feature to support them is not such a bad idea.

Re: Beep Media Player / Hebrew song names

Correct me if I'm wrong, but I don't think that people use UTF-8
filenames yet. A small test I've made shows that even KDE saves hebrew
filenames in a non-unicode form.

I think that Windows behaves in a similar way.

Beep Media Player / Hebrew song names

[Oren Held]

Hi,

xmms is the last software left where I have to read hebrew backwards.
I'm waiting for the gtk2 port for quite a long time and it won't go out,
but apparently I'm not alone. Beep Media Player (BMP in short) is a fork
from the xmms tree which already implements gtk2, and works pretty fine
(with few bugs still, it's a beta).

However.. I still cannot see my hebrew songs well: because now with
gtk2/pango, it expects filenames/id3 in the unicode format, which I
don't use (I assume most of us don't). I want to suggest the BMP team to
add an option 'no unicode filenames'. I just don't know gtk2/pango too
well and I'm not sure whether that's exactly what they should add in
order to make us happy.. I assume they just have to use some
iso8859-8->utf-8 converting function (because if we want pango to render
it fine, with bidi, it should convert the non-unicode text to unicode).

Anybody has something smart to say?

Re: internet services - server farm

[Oren Held]

Hi,

I don't see why it should be problematic, if each daemon accesses its
own files and there are no collisions.. (you know, NFS is designed for
MULTIPLE clients accessing it) - unless you mean to run two apaches at
the same time using the same log file, for example? but why to do that?

You can use heartbeat (http://www.linux-ha.org) to make the servers
monitor each other and when one is down to do a failover and take its
resources (i.e. run apache and become the web server instead of the one
which just died).

Note that your suggested configuration doesn't sound too good, because
you have a SINGLE nfs server, which is a potential SPOF (Single Point of
Failure) - if it'll die, your whole 'server farm' would die.
(There are many ways - not all are good ofcourse - to have a highly
available NFS server as well, try to get some info in www.linux-ha.org.

Re: Compiling RealTek 8139 driver whit error

[Oren Held]

Hi,

Where did you get this rtl8139 driver from? Is it supposed to compile
with Linux 2.4.18 at all?

Best thing would be using the driver that comes with the kernel; thus,
if you have problems with 2.4.18, just upgrade the whole kernel.

Re: live website mirroring

[Oren Held]

Hi,

Heartbeat can give you solutions for that.. The only real problem is
indeed the storage which you want to be synchronized.
High Availability clusters should provide a way for having shared
storage (i.e. scsi disk / JBOD connected to two servers), while the main
node is down, the other will mount the disk.

(Note that there's a big risk if two nodes mount the same storage. The
cluster should be connected with at least two internal cables so it
could monitor each node even when main network is down)

Anyway you'd better read some in www.linux-ha.org . Also note that
RedHat has its own HA cluster solution (pirhana I think) which comes
with their RH Advanced Server, which I have no experience with.

Winbind, samba 3.0

[Oren Held]

Hi,

First of all Shana Tova to all the IGLU people =)

And for less important things:
Samba 3.0 was just released.
I wonder whether Samba's winbind (A mechanism for reading unix account
info from MS Windows DC) grew mature recently..

Does Anybody have a good/bad experience to share? :)

Interesing. Though I still don't understand why would it not sort 'ab c'
and 'a c' in the correct order on Mandrake, but it's fine on Debian
(when LC_COLLATE is en_US).

I've checked it and it's indeed LC_COLLATE. I was too sure it was find
:) (Yatzati Leitzan kmo she'omrim)

Anyway something is still very strange. It happens even when LC_COLLATE
is en_US, at least in my Mandrake 9.1. Sort works as it should only when
LC_COLLATE is unset, C or POSIX.

Anybody has Mdk 9.1 and can approve it?

Sort weirdness

[Oren Held]

Hi,

I've just encountered one of the strangest bugs I've seen in Linux..

Just like an amateur Operating System, one of the core unix tools - sort
- behaves different on different Linux (or more correct: sort) versions.

When I try to sort the next input:
ab c
a c

It makes sense that 'a c' would come before 'ab c', and this is how it
works with coreutils 5.0. But on an older version (I'm not sure that in
ALL the older versions - actually textutils 2.0.21 works well) the
results are vice versa.

This really sucks.. A basic unix tool did not work the way it should,
and one day they just change the way it works, a simple act which might
affect MANY programs that relate on this.

I've experienced a related problem with autofs (check out the sort
command in /etc/auto.net), but that's just one place it might happen.
