This sounds good. I and many others could give good talks on this -
including the use of third party patches, etc. A short "but this is how you
do it on Debian" would certainly be interesting for sysadmins.

2.2 supports PDC for NT domains too, one of the major reasons why it was
released. This is one of the things I had in my "sysadmin-related" set of
talks to do, especially after last month. :)

Doing a /bin/ls is going to be much, much faster than using straight "ls",
unless for some reason you don't alias your ls at all (which I strongly
doubt).

There aren't too many other ways to do this, Alister... Unless you write
something up in perl/python/whatever tickles your fancy.

As I was converting over to XFS, sure. :) Remember that XFS is 2.4 only

That depends what you want to do within that block.
You could use 

  find -name "*.txt" -exec STH_TO_DO {} \;

If find doesnt find anything it will not execute

I think thats because *.txt is expanded (uner the shell) to a number of 
files and hence the evaluation is incorrect:

  if [[ -e one.TXT two.TXT three.TXT ]] ; then

a more relevant question is why do you want to? It sounds like you're
checking to see if a file exists before you do something to it (process
it, move it, delete it) this is a race condition and is considered to
be bad programming. What are you really trying to do?

Err, i was talking about win4lin 3.0 not samba 3.0, ie with samba 2.2 
installed as PDC, you could have win4lin 3.0 login to the Samba PDC (if 
win4lin 3.0 support nt domains networking). Just an idea for a

Aye, this is what Tridge was doing the other night, only with vmware. [ For
testing and doing stuff like this, vmware is better. For using normal
everyday Windows apps, or a cheaparse "terminal server", Win4Lin rocks. I've
yet to play with the proper Win4Lin servers. ]

[SLUG] Help I got hacked!!

[Andy Eager]

Hi all,

Help...

I've just managed to get myself back online after a few days of 
repairing damage caused by my first hack attack.

I got hit by 'luckroot' which basically changes a whole heap of stuff in 
/etc, /bin and all the usuals.  It seems to be an address / port scanner 
which collects stuff and emails it back to someone somewhere 


I fixed everything (I think except for /dev/hdc, /dev/console and the 
/dev/tty's) 

My question is:  Can I safely force rpm to reinstall the dev package ? 
(without screwing my hard disk settings in the process ?

Also, does anyone know of a service on the net that can attempt to find 
these holes in my firewall / sysconfig without doing damage ?

Thanks,

Andrew E.

PS:   Haven't these hacking  pr??ks got anything better to do with their 
time !!

You *need* to take the machine offline, and rebuild or replace it. This is
the only safe way to deal with it (and not having it come back to bite your

If someone has installed a 'rootkit' on your box, then you are in
big trouble and need to re-install from scratch. Do *NOT* keep 
any binaries from your current box - data files only. Without something
'like' tripwire to verify the integrity of your binary files, you
probably still have trojaned programs lying around. Although
the cracker may not have access, you simply do not know
what little goodies they have left lying around for you.

Re: [SLUG] if [[ -e *.TXT ]] ; then

[Alister Waller]

I want to move some files from one directory to another using a script.
I am using a cron job to call the script  and need to have the errors
emailed to me (which is the default)
The files are created with rolling numbers so will always be different
names, same extension.
There may be none, one or many files in the directory.

I am probably going about it the wrong way, my scripting is very rusty. I
could try the /bin/ls and grep the result and see if it is too slow. I just
thought there may be an easy way I have overlooked.


what I am trying to achieve:

I want to check to see if there are any files to move (otherwise I get an
error message generated if there are none)
Then move the relevant files

eg:

if [[ -e *.TXT ]] ; then
mv *.TXT /tmp
fi

RE: [SLUG] From newbie to...

[Chris Barnes]

I think a good area to start would be disk partitioning. I've tought a fair
share of people how to install linux and the area they stumble on the most
is partitioning. I know this is a really basic topic, but going from an o/s
like winblows where disk partitioning is seldom spoken of, to an o/s where
proper partitions are critical can be quite confusing and frustrating.

I also think that someone should discuss the relationship between Physical
memory and Swapped memory. Alot of people make a swap partition not knowing
how large they should really make it. Sure you can make your swap partition
1 meg and linux will boot fine, but how will things work differently if you
have 192Mb Physical, and only 1Mb Swap, or 8Mb Physical, and 192 Swap.

Its little but it can greatly affect the operation of linux, and people need
to know this when they install linux...well thats what i think anyway.

Re: [SLUG] Help I got hacked!!

[Andy Eager]

Thanks for that lovely piece of information.  I guess the key to the 
whole thing is to have a reasonably quick and easy way of installing 
from scratch without having to go through all the headaches associated 
with a 'clean install'.

Fortunately I keep all data backed up, so thats not a problem but having 
built the machine from scratch as a humble newbie only 6 months ago 
( I couldn't even spell Linux...) I've got stuff like nfs, ntp, 
named, samba etc, etc which all just 'evolved' over time. 

Wouldn't a reasonable compromise be to do the following:

verify each installed package:rpm -V -a
(Now we know each package is OK)

for each file in all directories except home, do:   rpm -qif 
(If it doesn't belong to any package then warn user)

The problem I have is that it will probably take me days to rebuild (and 
re-remember) everything I did over the past six months in terms of 
administration.  Then having done that, the same thing happens 
again. (because I still don't know how they got in)

[SLUG] Gnome 1.4 - Mozilla / Abiword bugs

[Andy Eager]

Has anyone downloaded the new version of Gnome 1.4 (the new 1.4 not the 
old 1.4 released a while back). 

I thought the first release was pretty good, Mozilla not too slow 
(though slower than ye old Netscape 4.7x), and Abiword only crashed 
every now & then.

I got the latest release from the ximian site last night, and loaded it up.
Now Mozilla mail (the funky new bluey / grey look) crashes when you try 
to compose an outgoing email (or forward an existing message).

Also Abiword seems to be even less stable and they have removed the 
'classic' gnome look as an option on startup.


Anyone having similar problems ?

Andrew E.

You should be able to clean install, and go through the /etc in the backup.
That's probably your quickest way to getting it up, but more importantly
getting it back up secure.

Well, I wouldn't... :)

/etc on your backups will save you. There haven't been many cases for which
a rebuild and full copy (overwriting the newly installed stuff) of /etc
haven't worked for me. Thankfully, I haven't had a box abused in such a
fashion thus far. :)

I only use Ximian GNOME at work, and at the moment we're stuck with a
dial-up connection so haven't upgraded yet. If no one else has tried, we can
always find out from the Ximian monkeys (try their MonkeyTalk app, or #gnome
on irc.au.gnome.org).

Think of it this way - you now have a valid reason to do an
rm -rf / :-). IMHO you really should start over completely -
yes, it's a hassle, but much less of one then not doing this
and having the nagging doubts that there may be something on
the system left over from the attack that's doing things you'd
really rather it didn't...

This is one reason for keeping a paper notebook in which you write down
everything you do on the system.

Assuming they haven't installed a trojaned version of rpm or similar.
You can only be sure the packages are OK if you're getting them of your
installation CDs, downloading from a trusted site and checking
signatures and so on.

Again, only if you can trust the version of rpm on your system. And you
really can't at this stage.

Ah, don't go there. Hackers *are* good. You got burnt by crackers.

The major reason they have problems is the difference between
distributions. For example - those that use the /opt directory need
either a separate partition for it or a very large / partition whereas
those that put software under /usr etc can get away with a small one.
SO yes, a talk on partitioning would be useful as long as it is NOT
hijacked by the poor deluded Debian junkies ;-P

A talk on the GIMP would also be useful.

Do you think?  I'll jump on the "Mozilla is good" bandwagon and profess
that I uninstalled Netscape almost 6 months ago.  I only use the browser,
and it's very fine.
As for Abiword, well, it's never crashed on me, but in the few documents
I've actually written with it, I had a lot of problems with the Styles
selection.  Trying to change from a Heading style back to plain text
doesn't work.

Have you downloaded and installed any new mozilla themese?  I had problems
with mozilla refusing to start at all.  This was solved by deleting my
entire .mozilla directory.  You might want to try doing that (but make a
backup first!)

*shrug*  Haven't really run it.  But, at least on my machine, it starts up
and looks exactly the same as it used to.

That means you can have a kickarse Samba 2.2 server, with full Windows NT

hello,

i was doing a search on google about reiserfs and win4lin and noticed
that somebody (Jim Clark?) was trying to do it without success.

report: win4lin 3.0 + kernel 2.4.4 + reiserfs works perfectly.  i even
munged it to work properly on a Debian system :).

i'll put up a webpage about it sometime soon if i get enough replies to

Yeh, I know and thats the problem.  They upgrade their packages  (quite 
considerably ) and still called it 1.4.  I know that's like having 
RedHat 6.2 with a 2.2.19 kernel, but at least in RedHat's case, the 
distro release does give some indication of backward compatability - Not 
the case here I can assure you.

If you keep a copy of the redcarpet package directory  
(/var/cache/redcarpet) somewhere on your network and then copy it back 
to /var/cache/redcarpet when you do your upgrade, it only takes an hour 
or two (closer to two but not 7 - 8 hours as the full 115 M from scratch 
would take).

Well, every GNOME package is versioned separately. Ximian are currently only
shipping their somewhat modified GNOME 1.4, plus security updates, and a
couple of packages that have been released post-1.4. We should be seeing a
1.4.1 release soon enough, thanks to Seth and Kjartan. :)

It certainly works with netscape 4.7x.

Interesting point there. We don't seem to have had any discussion on slug
about the recent LSB 1.0. (Presumably in this context that LSB 1.0 doesn't
look so great to 'Debian junkies', certainly a number of people on
debian-user have complained about the preferencing of rpm over deb, even
if they clearly have little knowledge of rpm :-).

Vaguely throwing out the question:

What do people think of the LSB 1.0 standards?

[SLUG] GnuPG keyfile fun

[Matt Hope]

So I've finally decided to join the masses, and organise myself a GnuPG
keyfile / sig / whatever-the-hell-its-supposed-to-be-called.

I've been through the documentation, and just have one query.

I grab jdub's key (this is an example)
gpg --keyserver www.pgp.net --recv-keys 565B38F9

Coolo, I can verify mails that jdub signs.
Now, to the 'web of trust' stuff..

If jdub signs somebody else's key (say Crossfire's), and then re-uploads
his key to the keyserver, I would have to check the keyserver and download
it again so that I can trust Crossfire (if I set the appropriate trust
stuff for jdub's key)

Is there any way to update the keys I've got, or any way to relise that
there is a new key to download ?

Re: LSB 1.0 (was Re: [SLUG] From newbie to...)

[Jeff Waugh]

> What do people think of the LSB 1.0 standards?

Well, yeah. I was hoping that Heracles wouldn't drop the "How to annoy a
Debian user talking up the LSB" cluster bomb. Lucky me. ;)

I think it's very good, and very worthwhile. But yeah, I have a little bit
of a niggle with the packaging section [*]. Excellent work on a very tough
job though, and I hope the many not-quite-LSB and FHS distros take on these
standards soon.

- Jeff

[*] Whilst the idea of a standard packaging system is important, I don't
think it offers any distinct advantages to users at the moment. Developers,
yes. Proprietary software vendors, yes. Users... Not really.

In the blue corner, we have RPM, which is widely known, and has plenty of
third party support.  In the red corner, we have deb, which is known well
throughout the Debian community, and allows for the incredibly anal
retentive distribution that it is.

Most RPM-based distro users claim to have an advantage in that they can get
RPM packages of whatever they want, anywhere. Most Debian users don't use
third party (defined as non-Debian official trees, or at least non-Debian
developer maintained) packages at all.

My perspective is that I prefer to use either the packages that are
available (or that I can contribute) to Debian, rather than use mediocre,
middle-of-the-road RPMs designed for various distributions that I may or may
not use (Mandrake vs. Red Hat vs. SuSE vs. Conectiva, etc.)

But that's just me. :)

Umm, nope - it will no longer work with 4.72.
SWMBO had just gotten used to internet banking on 4.72 on linux when St
George started rejecting it. I'm trialling 4.76 and it is worse
(reliability wise).

SWMBO is so P'd off she has gone to phone banking (quicker).

It works fine in NS 4.7.  The "bouncy keypad" only accepts the first
number of your PIN and then beeps for the next three.  Ignore the
beeps -- it actually takes in the PIN and works fine.

No success with Konqueror or Mozilla though :(

[SLUG] NVdriver not auto loadin after kernel upgrade

[Mehmet Ozdemir]

Hello All,

I recently upgraded the stock Redhat 7.1 kernel to 2.4.3-12. While the 
kernel update went thru fine, NVdriver no longer loads on boot.

Just to be sure I remove the old kernel rpm (for NVdriver) for 7.1, 
downloaded the src.rpm, rebuilt it under the ne kernel and installed it. 
Yet it still will not auto load on boot. If i run /sbin/insmod NVdriver 
it load w/o problems from /lib/modules/2.4.3-12/*** etc etc.

In my modules.conf a have the following:
alias char-major-195 NVdriver

Am I missing something obvious?

[SLUG] Geforce MX400 glitch under X

[Mehmet Ozdemir]

Hello Again,

I recently upgraded my video card from an AGP TNT2M64 to Geforce 2 
MX400. Since new the MX400 have been glitching in X, it did it in 4.0.3 
and does it in 4.1.0, The problem on happens in 2D mode where a scanline 
or two will "glitch" sort of like when you a power surge, most of the 
picture is fine just a couple of scanlines, apear to be random in time 
and where it happens on screen.  The card work perfectly in 3D.

Things I have tries so far,

different X, currently 4.1.0
enable/disable AGP/AGPGART
change BIOS AGP speed NORMAL/DEFAULT/FAST
AGP Apearate size, tried 8, 16, 32, 64, (currently on 256 just the the 
hell of it)

So far I have been unable to resolve the problem, I don't want to go 
back to the TNT2 as the Geforce seems alot smooted in quake and tuxracer !!

System Specs:
Abit BF6 MB
PIII 500E, (clocked at 120 X 5 = 600 MHZ), yes have tried clocking it 
back to 500 the glitch is still there :)
512 MB RAM
Geforce 2 MX 400
SB PCI 128
Tulip LAN

Any ideas on what could be the problem could be?

(assuming comma delimited)

sort -n -t, -r -k 2 | head -n 1 | cut -d "," -f 2

See the sort/head/cut man pages to decipher.  In short, it numerically
sorts in reverse order, seperating the fields with a ",", and using
field 2 as the sort key.  It then takes the first line, and then removes
all but the second field.

I may have the field number off by one.. a quick moments fiddling will
find out.

And you'd do the almost the same for field 3, of course.

Or in python (1.5.2):

#!python
import string, sys

if len(sys.argv) < 1: 
print "Usage:  "
print "e.g. find_max.py datafile.txt 2,3"
sys.exit()

# Turn the "2,3" into a python list [2,3]
max_list = map(int,string.split(sys.argv[2]),",")

# Initialise the result list to the appropriate length.
# I'm assuming you aren't worried about negative values.
max_values = [0.0] * len(max_list)

# No error checking is done... if something unexpected happens, tough.
for line in open(sys.argv[1],'r').readlines():
# Assume comma is the seperator
fields = string.split(string.strip(line),",")
for pos in max_list:
max_values[pos] = max(max_values[pos],float(fields[pos]))

# Iterate over two lists simultaneously
for pos, value in map(None, max_list, max_values):
print "Field %d has a maximum value of %f" % (pos, value)


Note that this script will find as many maximum values as you like at
once.  It's more verbose, but it ought to be faster than the
shell commands on larger files, as it doesn't need to sort the 
data first.  It's also completely untested, but it looks ok...

It's not a very interesting script, but I thought the list could do with
some variety from the usual perl gunk ;)

I can't comment about Abiword, but I'm sending this email to from a 
fully up to date Ximian machine and Mozilla 0.9.1 appears fine, infact I 
was using the non ximian Mozilla 0.9.1 rpms since they were available at

Or, to use a pile less memory :

cut -d "," -f 2 | sort -n -r | head -1

ie, trim the excess data _before_ you load it all into memory for sort.
Passing -u to sort would probably use a little less memory too if you've
got duplicate data in that column.

That said, you'd be better doing it in a way which wouldnt load anything
into memory, like awk (presuming positive numbers)

awk ' $2>A { A=$2 } $3>B { B=$3} END { print A,B } '

Perl is another option, but I doubt you could do it any smaller than the
above...

Why didn't you say so!! :)

nawk -F',| ' 
'!/^PD/{continue}$2X2||!X2{X2=$2}$3Y2||!Y2{Y2=$3}END{printf"(%s,%s)

will do the lot for you - including looking after the space/comma, the

(Under Solaris you need to use nawk to get this to work. Under Linux
normal awk should work as from memory awk/nawk/gawk are all the same).

Mike,

It works fine for me under netscpae in linux.

the "bouncy keyobard" looks like its not taking your PIN, ie stops after 1 keystroke, 
but actually takes it all.

The linux version of the app is the old version, under windows you get a new version 
that is alot more spunkier.

Give it a whirl.

win4lin doesn't have to support 'nt domains'. It, as has been mentioned
before, runs a copy of Windows under Linux. It supports whatever Windows
supports.

The real question is: Does the versions of Windows (95 / 98 / ME?)
support NT Domain networking?

The answer is: barely.

Finally there isn't actually that much *new* and *useful* about Win4Lin 3.0.
Very little that you, as an end user, would notice I'd wager. Will you
notice support for SMP Linux kernels? Will you notice suport for 2.2.x
and/or 2.4.x Linux kernels? Will you notice support for different Linux
locales and charsets and input methods?

You also need to try and identify how the cracker got in. You could rebuild

try and restrict these services only to the hosts that you need to serve.

[SLUG] Linux Cable Modem

[Phillipus Gunawan]

I had a cable connection with optus. The way I 
setup it in my eth0 is:
 
editing /etc/named.conf ---> adding the 
following lines after the 'directory' line with:
    forwarders(x.x.x.x; y.y.y.y; 
};
    allow-quesry { 192.168.0/24; 
127.0.0.1/32; };
 
on my 
/etc/sysconfig/network-scripts/ifcfg-eth0DEVICE=eth0 BOOTPROTO=dhcp 
ONBOOT=yes
 
And last one: /etc/sysconfig/network 
fileHOSTNAME=my_isp_assigned_name 
And the very last one: /sbin/ifup 
script
I change the 'calls' so the calls look 
like
/sbin/dhcpcd -i $DEVICE -h $HOSTNAME
-and-
/sbin/pump -i $DEVICE -h $HOSTNAME. 
 
 
This configuration works properly on my box before. 
2 days ago, I re-complie my kernel with the newest one. And now, when request 
the ip (dhcp) from my cable sever (eth0), it always fail.
 
Anybody could help me?
Thank You.

Installing Nessus somewhere and scan your machine after the rebuild will help

anybody got some hints..??

I have 2 NICS where  eth0 is internal and eth1 is external.

EXTDEV="eth2"
INTSN="192.168.0.0/24"

 /sbin/iptables -A POSTROUTING -t nat -o $EXTDEV -s $INTSN-d

[SLUG] Detective skills - weird HDD problem

[luke]

The other day I mailed out about the new PC I'd happily installed RH7.1
on, in a 4-IDE controller motherboard with 2 ATA100 drives and 2 older
EIDE drives, and how I managed to get it booting off drives past the
1st 2.

Optus Cable is due tomorrow arvo to install a cable modem - this is the
reason that I bought a copy of Windows 98 for the new machine.  :-(

Anyway, last night I tried to boot up '98, just to make sure all was
well, and it wouldn't boot.  The HDD activity light flashes for about
0.1 secs every 8 seconds, and the boot proceeds a little further.  It's
like the drive is timing out after an initial successful read.

The old drives are now slaves to the 40Gb drives - on Sunday they
stopped being recognised ,on the 4th IDE controller, and in desperation
I pulled everything apart and shuffled all the drives around so that
the cables reached everything, and fixed up all the drive device names.
The (suspect) 4th IDE controller is no longer in use.

After that it seemed good.  One odd thing though, was that while
everything looked good and worked well under RH7.1, when I booted up
RH6.2 from the old 8Gb drive, I got lots of "/dev/hdf: lost interrupt"
errors while it was booting - in particular, while it was doing the
partition check on hdf (the older 4Gb drive); similarly on hde (one of
the new 40Gb drives).  Ditto for hde, the new 40Gb drive that's master
of the pair (on the 3rd IDE controller).

The period between "lost interrupt" error messages, remembering, was
probably also about 8 seconds.  It took maybe 3 minutes for Linux to
give up on the drives and let the boot proceed without those drives.

So, using RH7.1, I copied the home directories off the 4Gb drive and
onto the 8Gb one, make a symlink for /home on RH6.2, and booted up with
hda=noprobe and hdf=noprobe to get the old RH6.2 system working.

Win98 is on the 1st 3Gb partition on hda and RH7.1 on the next, on the
same drive.  And note that it's the 1st primary HDD.  Yet Windows 98
won't boot.

So, my question (in desperation) is, does anyone recognise these
symptoms? I'd think it was hardware except that everything works well
under RH7.1.  It's just the older OSes - RH6.2 and Win98 that have the
problem.

The problems that made me think the 4th IDE controller had simply
failed seem suspicious/significant.  (Looking at old /var/log/messages,
I noticed that every time the 4th IDE controller worked well, the RH7.1
boot had autosensed the BIOS properties of the 2 old drives on that
controller as hdX:dma, and every time it failed it reported them as
hdX:pio.  Yet there is no BIOS option for fiddling that.  I wondered
whether it was randomly sensing it as one way or the other.)

If no one has experienced this, then there is the option of installing
Windows again.  But I'm scared that may wipe out my Linux partitions,
and since it seems almost like a hardware problem, I'm not at all
confident that a re-install wouldn't make things substantially worse.

The only other option I can think of is to get the motherboard
replaced, but again, since everything *was* working fine under Win98,
and *does* work fine under RH7.1, it may not be the solution.

I should finally note that I've installed no extra sw on Windows; I've
not really touched it.  The only change was putting LILO on the MBR,
and it was still working fine after that.

All I've changed is the cabling and physical arrangement of the drives,
and some BIOS settings for the order of devices that the system will
boot from.

Last thing I tried was removing "linear" from lilo.conf and re-running
lilo, but that made zero difference.

Any consulting detectives out there?  I'm certainly willing to pay for
help on this one.  I'm expecting that I'll have to ring Optus and
cancel tomorrow's installation, to be honest.  Then arrange another
some weeks down the track.  :-(

FWIW, the motherboard is an Abit SA6.

Yes and it rocks. It has so many more really good options that is useful
to spend the time to learn it and to re-write the rules. Re-writing
is not so much though, its minimal.

There could be another problem too.
>From the MAN page:

   --modprobe=
  When adding or inserting rules into a chain, use command to load  any

  extensions, etc).

MATCH EXTENSIONS
   col is specified, or with the -m or --match options, followed by the matching 
module name;  after  these,  various
   extra  command line options become available, depending on the specific module. 
 You can specify multiple extended
   match modules in one line, and you can use the -h or --help options after the 
module has been specified to receive
   help specific to that module.


So you might need to explicitly LOAD the module (nat and masquerade).
I had to do this to use the MULTIPORT module.

What kind of motherboard is it?

I know RH 6.2 was using a late 2.2 kernel (.17 or .19) and RH 7.1 defaults to a 2.4 
kernel (no idea what revision)...

It might be the chipset and it's driver not playing nice...

For a while, Trelos^H^H^H^H^H^HNetraverse were releasing Win4Lin as Debian
packages, but they stopped when Win4Lin2 was officially released.  This is
no great loss.  The .debs were just a quick conversion; they installed into
/opt, and behaved exactly as the rpm packages did.

Luke,

If you only need win98 to get the optus cable done, don't even bother 
poluting your hdd with it. You can get @home installed without it, just 
use a bit of social engineering.
When I had @home installed I didn't let the tech touch my computer.

Here are some tips. When the installer turns up, tell him that:

- The computers broken and you'll install the software later.
- Say you've had optus cable before and you know how to do it. (software 
that is)
- You could say your working on very sensitive work stuff under an NDA 
and you cannot let him have access to the machine.
- Put a bios password on and tell your spouse/mum/dad has the password 
etc etc.
- If all fails just slip him a 20, a 6 pack etc etc.

At the end of the day all he cares about is getting the install done and 
your signature on the work order.

Then once he's gone spend a total of 20 secs setting up linux to connect 
to @home.

I use Abiword 0.7-13 and it also seems ok but does crash opening certain
m$word documents. Also seems to stuff up the formatting sometimes. With
new documents created in abi (xml) it doesn't seem to be a problem.
0.9.0 is due out soon (no deadline given, no deadline missed :) but it
looks pretty good. Maybe interested sluggers could have a bug triage
day. It seems to me that getting good bug documentation from users on how
to reproduce the bug is a constant headache for OS projects. I logged a bug
on Mozilla and sent them a html test case and they went nuts, reproduced
the bug and fixed it almost straight away. So if Abiword crashes maybe you
should send them step by step instructions and an example file that breaks
it. See that's our side of the deal, as OS users (sorry R Stallman make that
FSF/GNU users) our side of the bargin is to log bugs and give good bug
reports rather than just bitch about a product being unstable.

On a related note, it appears upcoming Python releases will be GPL

That was probably me :)

Way back in the win4lin 1.0 days, win4lin would not work on resierfs
partitions.

I eventually got around to tracing the problem, and hacking a workaround
in the
reiser statfs function.
This is no longer required, as version 2 and 3 work properly.

RE: [SLUG] alternative file systems

[Booth, Christopher (Aus) - ATP]

Dumb question time

Are there conversion tools to convert from ext2fs to xfs or reiserfs ?

I use reiser on everything except my boot partition {I wasn't sure if I
could - still aren't, really}, and it's great.

Mounts them so fast after a lockup {which I have occasionally - bodgey SMP
bios on the motherboard/processor combination} compared to ext2 it's not
funny.

As a comparison - a 2 gig ext2 partition on a UltraWide SCSI {80 meg}
device takes about 4-5 minutes.

A 5 gig partition on an IDE {Ultra33} device takes about 4-5 seconds.

I love it.

Simpler than mkfs.* and tar? Sorry, not thus far. :(

Here's a conversion walkthrough for reiserfs:

  http://www.namesys.com/change_fs.html

I did mine differently, by having a backup / partition and swapping between
it and the proper one. First, I made a partition and formatted it as XFS,
then copied everything in my normal / partition to it.  Booting into my new
XFS / partiton (which happened to be on a different drive altogether),
everything worked, so I just formatted the proper one as XFS, and went with
that.

[SLUG] my next stupid question

[Alister Waller]

Hi,

another stupid question.

I am running a script from a cronjob. part of the script is a for loop. see
below:

for i in `ls *.TXT`
do
 cat $i >> newfilename
 mv $i /tmp
done

Now, if there are no *.TXT files then I get an error sent back to the owner
of the crontab file.

I don't want to see this error.

I know I could remove the errors at the cronjob level but there are other
errors in the script I might want to see. I just don't care if there is
nothing listed for the loop to function.

regards

Alister

Why cat? cp $i newfilename would do pretty well.

"2> /dev/null"

If you're not interested in the stderr output of the loop, put the entire
loop in parentheses and direct stderr to /dev/null from it.

A fairly common idiom for this is:

fileList=`echo *.TXT`
if [ "$fileList" != '*' ]; then
...(insert other stuff here)
fi

That should do what you want.

he's got a >> there, not a >, so cp $i newfilename isn't the same :).

a better solution would probably be:

for i in *.TXT; do
cat $i >> newfilename && mv $i /tmp
done

(1) you can just do *.TXT; no need for `ls *.TXT`.

(2) the && checks the error code returned by cat, so that the mv is only
done if there was no errors.

ie

( for i in *.TXT; do cat $i >> newfile && mv $i /tmp; done ) 2> /dev/null

to make Jeff's last comment completely unambigious :)

(can you replace the () with {} for that loop?  not sure if you can
 redirect the entire loop to /dev/null if you don't run a subshell.)

No it wouldn't.  Note the `>>'.

Try this:

  cat *.TXT >> newfilename 2>/dev/null
  mv *.TXT /tmp 2>/dev/null

Or even:

(cat *.TXT >> newfilename && mv *.TXT /tmp) 2>/dev/null

Note that this will create `newfilename' even if there are no files
matching `*.TXT'.


Cheers,

John

Doh! I didn't actually run this, obviously. The 'if' clause should be

if [ "$fileList" != '*.TXT' ]; then (etc...)

ALister, as in the last question, you dont seem to be aware that wildcard
expansion is done by the shell, not by the command as in MS-DOS.
  So the 'ls' does nothing useful, and may cause errors. Shells are
complex, and worth reading about.
