Since the Scubatoolkit advertised some capability my program didn't 
have,
and I am working on some stuff that Scubatoolkit was missing, I thought,
hey... maybe this can be mutually beneficial  So I downloaded it and am
now trying to get it to work so I can see if there is anything I may be able
to offer.

 


Follow these steps (url compliments of Vince)

1) cd
2) wget 
http://unc.dl.sourceforge.net/sourceforge/scubatoolkit/scubatoolkit_0_0_4_src.zip

3) mkdir scubatoolkit-0.0.4
4) cd scubatoolkit-0.0.4
5) unzip ../scubatoolkit_0_0_4_src.zip
6) javac *.java
7) java Scubatoolkit

Each time you make changes to the java code redo steps 6 and 7.

Re: [luau] Java question

It's been a few semesters since i've done any java programming, so i may 
be way off base here, but my initial guess is that you need a space 
between the period and Scubatoolkit.


The reason I say this is, the java command has one mandatory argument, 
namely the class to execute (or possibly a jar file), and the -cp 
commandline argument also has its own mandatory argument, namely one 
directory to search in when trying to find classes.  So currently there 
aren't enough arguments for the command to make sense.


So, again,  i think you want:

java -cp . Scubatoolkit

Also, I think that java will automatically search the current directory 
for classes anyway, so you can probably get away with just:


java Scubatoolkit

Re: [luau] State of Texas

[Ray Strode]

If you want to use OSS from the start, you can use python and
wxWindows and keep some of the modules you write when porting to
Plone.
 

I definately agree that code reuse is the way to go. 

One other option (other than wxWindows) is PyGTK/libglade.  It won't 
have the exact same look and feel as most windows programs (because it 
doesn't use native controls), but you get to build your GUI in Glade 
which is a pretty easy to use gui builder and with that you get the 
advantage of more natural separation between core program logic and user 
interface code.  I think wxWindows may have a gui builder, too, but I 
think it may be worth the effort to check both out.


Btw, with either option you get portability to Linux for free.

Re: [luau] Personal Touch (was anyone know of a good computer repair place?)

[Ray Strode]

1) Whirring sound (like a fan) when running which

The sound will sometimes kick into high gear and that

is the system's signal that it is about to crash.


If a walks like a duck :-)  It probably is a fan.


2) Sometimes the system boots and sometimes it
doesn't.  If it fails, I'll get the XP version of the
blue screen of death.  (The sceen isn't blue but the
text which indicates the crash address and other
diagnostic info is.)

3) If it manages to boot successfully, several system
failure errors are generated.  Sometimes that's eough
to halt the system, sometimes not.

4) If I can proceed at all (which lately is not the
case) then evetually the whirring noise gets loud
enough and then BOOM.


This definitaley sounds like your CPU is overheating.

I agree with Mike.  Your fan is probably bad, or possibly some wire or 
something
is block it from spinning properly (either could make your fan noisey). 

If i were you i would open the case up and see if anything is blocking 
the fan
If so, unblock the fan. 

If nothing is blocking the fan then pull the fan off and replace it.  
You may wanna
pull the fan off anyway to clear any dust bunnies that have built up

Re: [luau] Re: no answers from roadrunner dns

[Ray Strode]

That is a good explanation of the iterative lookup. However, it
is my understanding that the client does not normally perform
this.


Oh, could be.


I always thought it was up to the DNS servers configured on
your system to ultimately perform that role.

It certainly makes sense for dns servers to iteratively query other dns 
servers, but
to me it also makes sense that clients would want to.  Whether they do 
in practice,

I don't know.


To verify, I edited /etc/resolv.conf on a few systems to point
to different nameservers that I knew did not answer recursive
queries from external networks and could not resolve an IP
address that belonged to a third external network. (I tested on
Debian, FreeBSD, Red Hat, and Solaris.)


Well, sounds like you are right then.  Interesting...

For a small company and the right software, you might be able to
get away with running a firewall on a 386.
 


Note that for most 386's you are constrained to the ISA bus, which means
8 MHz and 16bits ~= 16Mbytes per second theorhetical maximum throughput.  
In practice you are going to get considerably less than that.  Probably 
okay for a 10Mbit

Re: [luau] Re: no answers from roadrunner dns

[Ray Strode]

I cannot explain why dig says things are OK while your own
resolver does not.
 

I haven't looked into this at all (don't really have time right 
now...maybe over the

weekend), so I don't know the answer either, but my guesses are the obvious
ones: either Road Runner's dns doesn't cache, or there is a bug in the
homebrewed client or a misinterpretation of its results.


That being said, if your DNS servers are not performing recursive
queries, then you will not be getting any name resolution outside
of the Road Runner network (and the support line would be flooded
with complaining customers).

This is incorrect.  Normally (when Recursion Desired bit is not set), if 
a server doesn't
know the answer, then it will provide suggestions for servers that are 
more likely to know
the answer.  The idea is, the client can then ask those servers.  If RD 
is set, then
the server goes out and queries other servers on its own and then 
returns the result.


This recursive feature is optional for dns server implementations.

Re: [luau] java on linux question - sorry, source inserted

[Ray Strode]

Uhm, for those people who program in Java on Linux, 


I'm not really qualified to answer, because I haven't used Java in
a while and I haven't ever used  a GridBagLayout,
but I'm going to guess, and it probably won't be much help you.

All of my speculation is based on guessed semantics from the names
of the classes.

is there any reason that everything here wouldn't stack up nice and 
clear at least horizontally? 


I'm guessing the fill member of the constraints object specifies whether 
the given control should
grow to fill any surplus it has in its cell(s).  I'm guessing that the 
BOTH constant means the
control should grow both horizontally and vertically.  I'm guessing 
gridwidth is the number of cells
the given control is allocated horizontally (something like colspan in 
html).  Are my assumptions

correct?

I think that the fact the buttons are different widths are a symptom of 
the problem, not the cause.
The grid columns themselves are different widths, and the buttons are 
configured to fill the entire
width of their respective columns.  I think if you set the fill member 
to 0 or NEITHER or NONE or
whatever the constant is called, then the buttons would be the same 
width, but the spacing

would look weird.  Am I right?

Now here is my completely uniformed guess at what might be going wrong:

I think your problem might actually be the labels.  They are probably 
going to try to prevent
themselves from wrapping or at least wrapping on non-whitespace as much 
as they are able.
So the columns with labels are probably as wide as the labels, which are 
probably wider than
the other columns, becuase the other columns contain controls that 
handle small space better

(e.g. the text controls scroll and clip, the buttons shrink, etc..).

If what i'm saying is right, then the first and fourth columns probably 
have the widest buttons.


Again, though, I want to make it clear to you that I'm just guessing and 
have no idea if that is

actually the problem.  I don't use Java very much.

Another possible guess: it wants a new contraints object for every add 
call, and by passing
the same reference around you are confusing it?  I haven't looked at the 
documentation, so

I don't know what it expects.

One general note:


for (int i = 0; i < 5; i++)
{
macroFunctionButton[i] = new Button();
macroFunctionButton[i].setLabel("Function " + i);
g.gridx = i; 


I think it would better, if you moved this down a line and changed it
to g.gridx++



add(macroFunctionButton[i], g);
} 




g.gridx = 5;


...then this line wouldn't be needed, yes?

Re: [luau] dhcp-146-41

[Ray Strode]

I noticed that, instead of the usual "localhost", the computer was 
designated, out of the blue, a name called "dhcp-146-41".  It was 
subsequently concluded that this was the source of all the problems 
(including inability to install printer driver, etc.)


Not sure why it's causing so many problems, but I can explain a little 
bit about how the process works on

redhat.

First, the computer requests an ip from the dhcp server (called DHCP 
request), then
dhcp server returns the computer's ip address and other network 
information, including the dns server
(called DHCP ACK [ACK is for acknowledgment]).  Some time during this 
process the file
/etc/sysconfig/network gets sourced and certain environment variables 
are set.  

If HOSTNAME is one of the environment variables to get set and it is set 
to something other than

"" or "localhost", then the hostname of the system is set to $HOSTNAME.

If HOSTNAME is not set, or it is set to "" or "localhost"  then the 
computer performs a reverse lookup on the ip
it was just given (by asking the dns server it was just told about). 
Whatever results from this reverse lookup is the
hostname assigned to the system.  If the reverse lookup fails, then the 
hostname is set to localhost.

Any fontconfig enabled programs will have access to them then.  

For programs not using fontconfig yet, you will have to install

Re: [luau] Mozilla 1.2.1 released

[Ray Strode]

 Adobe (and probably to some extent, Microsoft) owns the rendering 
engine, which is proprietary, and libraries for ttf.


Actually, I believe microsoft and apple own the rights to truetype.

I think that Adobe created postscript which was used to make scalable 
fonts, before truetype existed.  Then I think Apple created truetype to 
solve certain deficiencies with Type1 (postscript) fonts.  Microsoft 
copied apple and released itsown truetype implementation, which wass 
steadily developed for a few years, then Adobe and Microsoft allied to 
create the OpenType specification, which specifies a font format that 
can contain both postscript and truetype data.


The specification is freely available, but supposedly misleading and 
incorrect in places.  Nevertheless, from the specification and from 
experimentation, the freetype project created an open source library for 
reading truetype and opentype fonts. This library was first used by 
special independent x font servers (back in the XFree86 3.3.x days) to 
give X truetype font support.  Later, when XFree86 4.0 made its debut, 
it had freetype built in, so X could natively support truetype fonts.


Now there is Xft which also uses freetype.  See my other mail on this 
thread for more information about how Xft works.


  OTOH, while you cannot copyright a truetype font (or any other 
font), you can trademark its name.  Without a license, which is 
unlikely to be granted by Microsoft, a Linux distro cannot legally 
distribute many of the popular truetype fonts such as Times New Roman, 
Arial, or many Microsoft fonts (mainly because of trademark infringement).


Well you certainly know more about legal issues than me, so I'm curious. 
If you can't copyright a font, then why don't people just take fonts, 
rename them, and then redistribute them?


I know microsoft for a while (like a couple of years or more) made there 
Web Fonts (all the really good fonts they have) freely available to 
anyone who wanted them.  The license also didn't restrict redistribution 
of the fonts, so even though microsoft no longer distributes them, you 
can still get them legally online.  Now i'm wondering if the reason they 
didn't restrict redistribution was because they legally couldn't?

Re: [luau] Mozilla 1.2.1 released

[Ray Strode]

I saw that on the mirror, but was not sure what the difference between vanilla 
and xft are.  What does xft stand for?
 

I'm not sure what it stands for, but it's designed to fix the mess 
currently associated with X and fonts.  Basically, fonts are normally 
stored on the font server (the display part of X), which presents major 
headaches for programmers and application designers.  One such problem 
is, since the server is in charge of displaying its own fonts there is 
little opportunity for the client (the executing, cpu-using part of X), to

control how the font should be rendered.

Xft is a library for using fonts on the client-side.  It uses fontconfig 
for accessing fonts, freetype for rasterizing fonts, and the X Render 
extension (if available) for rendering the fonts.


fontconfig is a system setup for storing and retrieving fonts. 
Basically, you drop a new font into a preconfigured directory and then 
the font is installed and usable.  Also, applications that use 
fontconfig, rather than having to specify big, nasty, X font 
descriptions (those long things with lots of hyphens and asterisks), can 
just ask for "Courier" or "Times".  And fontconfig will follow certain 
configurable heuristics for choosing the best font to reply with.  Note 
it has no dependency on X, so it is potentially useful for more than 
just X applications (for instance, printer drivers, or console-mode 
documentation packages).


freetype is a libary that can open font files (truetype, opentype, and 
other lesser formats) and convert fonts from their 
resolution-independent mathematical representations (as stored in the 
files) to pixels. This process is called rasterization.


X Render extension is an add-on for XFree86 (and the latest version of 
sun microsystem's version of X), which provides functions for 
compositing onscreen images.  This is particularly useful for making 
fonts look smooth, because font's are smoothed by bluring certain rough 
edges with the font's background.  This process is called rasterization.


So there is a lot of really cool technology behind xft, but the only 
thing you will probably notice is that it gives you smooth looking fonts.

Re: [luau] Warren's walkthrough of MonMotha's firewall script

[Ray Strode]

I've not really used monmotha's script, forwarding to him...

--Ray


I've followed Warren's walkthrough of MonMotha's firewall script found at 
.
I installed the script on a computer running redhat 7.3. The only change I made
was that I used 192.168.1.1 instead of 192.168.0.1 for the firewall LAN gateway
address (eth1), because I have an existing Linksys router that had been using
that address and all my clients are already set up that way, I don't want to
have to reconfigure 17 computers when I swap my dedicated firewall for my 
router.


I can't get the firewall talking to the WAN at all. After I run the script,
I can't get the LAN to ping the firewall.

When I try to ping anything on the WAN from the firewall I get "network is not
reachable." This is true even before I run the firewall script so there are
no rules and default is "accept". I have set up the firewall with the same IP
number and gateway that the router had, I've disconnected the router from both
the WAN and the LAN, and hooked in the firewall instead.

I tested the cables. I tested the two ethernet cards. I reconfigured a client
to use the WAN address as a gateway and plugged it into the WAN NIC with a 
crossover
cable, the client was able to ping the firewall on eth0.

I am able to ping the firewall from the LAN before running the script. After
running the script, the firewall no longer answers ping. Is this what I should
expect?

Could redhat 7.3 have ipchains running by default and messing me up?

Could the IP# change matter? (Warren's walkthrough says use 192.168.0.1 as 
eth1's
IP#, the gateway address for the LAN, I used 192.168.1.1 instead.) I tried to
set the firewall up to be identical to the router it replaces, same gateway,
same IP#. The LED shows activity on the card attached to the WAN. 


Could the MAC change when I switch from the router to the firewall be confusing
my gateway so that it refuses to speak to me? I am at UH, not using an ISP.


Could there be a delay before things start working? When I switch things back,
it always takes a while before the router starts working again.

There is some stuff in the walk-through about the PCI slots using bus-mastering,
I have no idea what this is about, could that be causing my problem?

How can I tell whether ipforwarding is enabled and working? (That's how the
packets get between the LAN NIC and the WAN NIC, right? I see it in the script
output,but is there an explicit test?)

Since I can't reach the network even before I run the script, the script doesn't
seem to be the entire problem. But for what it's worth, here is the output when
I run the script:

Well, I've really only used vim, but I just tried vi on a SunOS box

and line numbering seems to behave the same way.  You are referring to
:set number

Vim does have a vi-compatibility mode that is on by default unless you have
a ~/.vimrc file.  you can force it on by

:set cp

But since I don't recognize any difference in behavior I can't tell you if
that makes a difference or not.

Please.  I just can't take it anymore.  
 

As Myles said, you can turn syntax off with "syntax off" (or :syntax 
off) in your ~/.vimrc, but
if you have the vim-minimal package installed then /bin/vi will also 
contain a less featureful
version of vi (no support for syntax highlighting, no support for 
multiple buffers, or split screen).


So in reality, you can use "vim" when you want all the features, and 
"vi" when you want a minimal

editor.

Re: [luau] ics412: operating systems

[Ray Strode]

I assume you mean for applications?  This seems to be the consensus.  I
don't know why people still use C for large applications, like GNOME.
C++ would be a much better choice.

C offers more portability and better abi compatibility than C++.  C++ 
compilers
tend to be more buggy than C (which contributes to the portability 
problem).  
C is better for making bindings to other languages (in part because of it's

better abi compatibility).

In my opinion C is a good language for libraries and application frameworks
(e.g. like GNOME), but I think applications themselves should be written in
something more highlevel like Python.

I think also that people tend to love the language they used seriously 
first.  
Miguel de Icaza did kernel programming before starting the GNOME 
project, so

that may help explain why GNOME uses C.


C++ from what I've seen (and experienced today) is harder to compile.


What do you mean?  You're not compiling C++ by hand, are you?  ;-)


I think he's saying that the syntax is harder to get right, so it takes
more changes to get the code to compile.

Re: [luau] kernel module, /proc filesystem, and mmap

[Ray Strode]

Hmm, it seems if proc_fops is set, these two have no effect.  That's not a

I took a quick peek at the code and it seems that it already initializes 
proc_fops, so maybe instead of

replacing it, you could just update it.

entry->proc_fops.mmap = ;
that way the default handlers for seek, read and write work.

Re: [luau] kernel module, /proc filesystem, and mmap

[Ray Strode]

I've never actually done any kernel programming, so I probably won't be 
of much
help (actually probably won't be of any help, i'm just shooting in the 
dark),

but...


I am trying to write a kernel module that shares a global variable between
a userland application and the module.  In the kernel module, I use this:

mode = ...; /* read/write for all... */
entry = create_proc_entry("jimen", mode, NULL);
entry->proc_fops = my_fops;

My guess is that you probably need to set entry->read_proc and 
entry->write_proc
also. (I don't know if you've seen 
linux/Documentation/DocBook/procfs_example.c

or not, but it seems like a pretty easy example to follow).


Where my_fops contains an mmap entry like so...

int var __attribute__ ((aligned (PAGE_SIZE)));

int
my_mmap(struct file *filp, struct vm_area_struct *vma)
{
vma->vm_flags |= VM_RESERVED;
if (remap_page_range(vma->vm_start, (unsigned long)&var,


offtopic, but that cast doesn't sit well with me (because whose to say
sizeof(int *) == sizeof(long) ?)
For instance on sparc i think that long is 32-bit and pointers are 
64-bit, so

a cast like that would cut off half the address's bits.

That said... I think it must be right because the kernel developers are 
a lot

smarter than me :-) and they've prototyped the function that way.


int fd = open("/proc/jimen", O_RDWR);
int *ptr = mmap(NULL, 4, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0);


The mmap system call seems to work without error.  


So /proc/jimen exists?  What happens if you cat /proc/jimen ?


If I add in MAP_ANONYMOUS to the flags, I am getting valid values and able to
modify '*ptr'.  But if the module modifies 'var', '*ptr' does not reflect
the change.  This kind of makes sense since MAP_ANONYMOUS means there is
no underlying file.


right.


 But without it, I'm not even getting a valid pointer.

You mean you are getting a valid pointer, but the value the pointer 
points to

doesn't change?

If you sent me your code, I wouldn't mind playing around with it.  I've 
always

kinda wanted to learn kernel programming.

Re: [luau] NFS problem

[Ray Strode]

I hope it's not in the kernel, it sort of "breaks" NFS to match the SGI bug.
 

Well actually I briefly looked at the patch, it's not automatic.  A 
patched kernel still has to turn on the compatibiltiy

mode with a kernel line option.(lh=1 or something like that)


so I tried [mount -t nfs 192.168.1.141:/abyss /tmp/somewhere] and it worked!
I guess localhost is mapping to 127.0.0.1 which is excluded  by my /etc/exports
file.

right.  



Now it works on the SG, but only if I use the command line. I had been using
their GUI filesystem manager, but it still can't find the /abyss directory.
 

Well, if you add it to your /etc/fstab then it should be just a one time 
change (weird that the GUI interface

doesn't work tho)


It even works on the SGIs with the old OS, so I guess the patch did get rolled
into the kernel. Or else maybe the bug is intermittent/slow to show a problem?

My understanding is with older versions of IRIX things like "ls" when 
there are a lot of files in a directory
won't work, but yea it's possible that they've found a way to work 
around the problem automatically.

Make sure that you have the port mapper running. /etc/init.d/portmap 
status should say

Could it be the filesystem format (ext3) causing a problem?


No.


Also, I want to use this setup with some SGI/IRIX clients running 6.5.10, which
has an NFS bug. Upgrading IRIX on the other SGs would fix it, but that is not
really an option right now. 

Just did a quick search and it seems that you can add vers=2 as a mount 
option
for your IRIX clients to force them to use v2 NFS which doesn't have the 
problem.

Re: [luau] getting system time in milisecs

[Ray Strode]

I have some code that loops with some real-time constraints, and I need to
check the time per cycle. 

Do you really need to check it per iteration?  I mean, in your case, 
could you move the timing outside
the loop and divide the result by the number of iterations?  If you do 
that, then you will get an average

iteration which will minimize the time spent timing.


The problem I run into is that adding "debug" to log the time is somewhat

inaccurate and impacts the loop. 

Not quite sure what you mean by "debug".  You mean the timing code is 
skewing your results?
Here's an idea:  say get_time() is your timing function (be it from 
gettimeofday() or clock() or whatever),
before you start your loop do a little profiling of the timing function, 
something like


before = get_time();
for (i = 0, total = 0; i < 1; i++) {
get_time();
}
timing_cost = (get_time() - before) / 1

Then you have a rough idea of what get_time() is going to take during 
your loop, so you can

subtract it out from the results.

On a side note, there is a syscall called times() which fills a 
structure that contains clock ticks since the
start of the  program.  It has two fields. One of the fields is the 
clock ticks spent in kernel-space and the other is
the clock ticks spent in userspace.  If you might be able to use it to 
isolate the times from parts of you program,

too.

Re: [luau] Apache question

One more question.the network is behind a router...so will the linux

Does the webserver have an outside accessible IP, or does your router 
NAT a single internet
connection?  If the latter, then probably not, unless you explicitly 
configured it otherwise.  Best way
to find out though, is to just check.  The hostname (mywebserver or

Re: [luau] getting system time in milisecs

[Ray Strode]

I'm pretty sure in a C class we once used something like x=time(0).  It
might require time.h or clock.h or something.  But that was a long time ago.

time() returns seconds, so i don't think it's precise enough for him. 
As an aside, time() takes a pointer
so (imo) it's better to use NULL instead of 0 (Unless of course you are 
using C++), or time(&x) will

work, too.

Re: [luau] getting system time in milisecs

[Ray Strode]

Another goofy programmer question, what's the fastest and most 
accurate way of getting the 


current time in milisecs within a program?  I've been calling 
gettimeofday, but was wondering 



if there's any better/faster way of doing it?


As far as I know gettimeofday() is the best way.  Remember the structure 
it fills contains
fields for seconds and microseconds, so if you want milliseconds you're 
goina have to do some
math (and probably use a 64bit type).  There is also ftime(), but it is 
deprecated.


What do you need it for?  If you want to benchmark some algorithm or 
something I think
you can use clock() (run it once before, once after, subtract and then 
divide by

CLOCKS_PER_SEC * 1000)

If you want to run some code after a specified amount of time then you 
can use alarm() or

setitimer().

Some boxes also have /dev/rtc which you can be configured (by 
ioctl()'s)  to send data from
1 time a second all the way up to 2^13 times per second.  (2^6 times per 
seconds is the max for
non-root users).

cache them for performance).


You might want to do this if you have a larger intranet.

Re: [luau] Digital Camera with Linux

[Ray Strode]

We use a Sony Cameras that work on a .jpg format floppy disk. Good
Quality and loads directly onto any OS with a floppy drive. 

You can get the camera for a good price at the Navy EX. 

JPEG isn't really the best format for holding raw image data because 
it's lossy.
It's an excellent format for saving disk space though (such as for the 
web or for storing

megapixel images on a floppy disk.)

Re: [luau] Ruby

[Ray Strode]

How many use Ruby to set up their website?

What are the pros and cons about Ruby?


I haven't actually used Ruby, but I read about it
some time ago.  It is completely
Object Oriented--more so than C++ or even Java.  
Even primitives and literals are treated as objects.  
It lets you assign code to field access ala C#'s properties,

eliminating the need for setters and getters.  I also
remembering it having some sort of new block structure
that's useful for iterators, but I don't remember the
details (I looked at it a couple years ago).  IIRC, it
uses symbols like perl for different types.  I'm not
sure though.  


All in all, if I had to choose, I think I would use
Python over Ruby for many projects, just because I think it
has a cleaner syntax.  But I would probably use PHP for web
stuff.

However when I do rpm -Uvh  to install it, it says package is
already installed, which is true, because the package is indeed
installed.

Note that -ql and -Uvh take slightly different arguments.  -Uvh takes a

a package name.  So if you do
rpm -Uvh foo-0.0.1.i386.rpm

rpm -ql foo

[luau] Re: CJK Input (Limbo 2 Gone from Mirrors)

[Ray Strode]

Thanks Ray.  Would you be able to show me how to input and print CJK 
characters in vim?


I'm sorry, but I don't really know how.   At one point I was playing XIM 
(X Input Method), but
I never really learned exactly how to set everything up.  I'll tell you 
what I do know.


Vim supports XIM, so if you can get CJK character input to work for any 
other XIM application

then the same method should work for Vim.

XIM requires what's called an input server.  Examples of input servers 
are kinput2, xwnmo

(Japanese), and xcin (Simplified and Traditional Chinese).

There are four different methods of input using XIM: on the spot, over 
the spot, off the spot,
and root window. Mozilla has a nice document that says the differences 
between those:

http://www.mozilla.org/projects/intl/input-method-spec.html

Vim only supports over the spot, off the spot, and root window.

When you run your input server, you'll need to be in the correct locale 
and have the correct
fonts installed.  


You can find out what locale's your system supports by typing "locale -a".

For instance, simplified chinese is zh_CN and japanese is ja_JP.  

You have to tell X Windows which input server you are using.  You can do 
by settings
the XMODIFIERS environment variable or by adding a line to your 
~/.Xdefaults file.

eg. type:
export [EMAIL PROTECTED]
or add
*.inputMethod: kinput2
to your ~/.Xdefaults file

Most input servers allow you to activate them by pressing shift-space or 
ctrl-space.


Last note, make sure you have a version of vim installed that supports 
multibyte
characters and xim, if you type :version then you should see +multi_byte 
and +xim

somewhere in the list of things.

That's about all I can think of off the top of my head.  I don't speak 
anything but
English (well and a Spanish 101 level of Spanish).  You might try search 
google,
or looking through the vim help files... (vim has excellecent 
documentation).  I
would try something like :help xim or something.  With vim, if you see 
something
of the form |Topic| (like a word in vertical bars), you can use the 
arrows (or

j, k, l, and h) to move your cursor to the word and then press CTRL-], to
jump to that specific topic.  CTRL-o will bring you back to where you were.

Re: [luau] RH 7.2 vs. 7.3 questions

[Ray Strode]

1) Is it worth going out and buying the boxed RH7.3 set, or is it cheaper
to just burn a copy of RH7.3 and buy the yearly subscription? Is there any
difference? The demo software doesn't really interest me that much, and I
the included docs the last time didn't seem that different from the
previous version.

Should I buy 7.3 pro? or just install 7.3 from CD's and buy the annual
subscription?


If you have a fast internet connection, maybe the service would be better.
You'll have money going straight to red hat that way too.


2) I'm building the machine mostly to be a server not a desktop setup.
Basically a LAMP setup (although I need to make it FP extensions
compatible for some work I do for clients). I need it to handle multiple
domains and email although traffic is very light. I'd also use it as a
SAMBA enabled storage area to hold files from winblows machines on a small
network at home.


Should be fine for that.  Not sure about the Front Page extensions, though.
(Never looked into that).


I was thinking of installing the basic system without the webserver,
mySQL, PHP and mail programs and hand install those items myself...Kinda
interested in trying qmail and using squirel mail to provide web IMAP
access to my email (when I can't use my laptop or regular workstation).


Well, I used to do things manually, but the already setup packages work fine
so I dont' hassle with it anymore.  I used to run qmail and courier-imapd
and it worked okay.  Now i'm just using the stock sendmail and uw-imapd that
comes with redhat.  It works good, too.


As gravy, it'd be nice to slowly start playing with X and remote X
connecting to server...


I have four machines at home.  One that's a server, one that has linux
and remotes from the server, and two that run windows/linux dual boot. When
on a windows box i can access the server using XFree86 compiled with 
cygwin.


I thought I'd seen some past posts by list users who have similar setups 


or who do this for business clients. (Was that you Hoala?)


Yeah, Hoala is i the qmail and samba expert of the group.

Re: [luau] use dd for disk clone?

[Ray Strode]

dd seems to be file oriented, but I guess you   
can just treat two mounted disks as files? 


It's not a good idea to do it on mounted disks (at lease read-write mounted
disks), but yes, you can just use the device names as if they were files.

What would that look like, use /dev/hda and /dev/hdb as 

stdin and stdout, something like that? 

Well, if you are trying to replicate one disk onto another, then that 
would work.
(Assuming the drives are identical. I'm not sure if it would work or not 
if, the

drives were different sizes/had different geometry).

so the command would be

dd if=/dev/hda of=/dev/hdb

or

cp /dev/hda /dev/hdb

If you want to make an image then you would do something like

dd if=/dev/hda of=mydrive.img

or

cp /dev/hda mydriveimage.img

If you just want to do one partition (say hda1), you would do:

dd if=/dev/hda1 of=mypartition.img

If you do your partitions separately, then it should be easier to
restore the data on a different size drive.

For instance,
dd if=mypartition.img of=/dev/hdb1

or

cp mypartition.img /dev/hdb1

One advantage of doing it by partition, is you should be able to 
actually mount

the image file as if it were a partition using the loopback filesystem.

mount myparition.img /mnt/mypartition -oloop

If you use / it would cause a problem 
because you'd be including your destination in your source, 
right? 

I'm not sure i follow you here.  If you want to do a raw copy, then / 
isn't even

related, because / is a filesystem concept and raw copies don't know about
filesystems, they just know about bits.

Isn't there also an issue regarding open files, etc.? When I  
clone a disk in irix, the manual says to do it in single user 
mode, I presume because you want all the files in a consistent 
state.  

Yes.  Like i said, better to do it mounted as readonly, or not mounted 
at all.  Single

user mode would be a good way to ensure that.

Anyone see a way of using dd to make a disk image file instead  
of cloning a disk?  


See above.

Would tar do? Tarball too big? Would tar be able to make an 
exact copy? Would it leave out .files? 

Yes, tar would work I think, but would be a lot slower, because it would 
work at
the filesystem level instead of the bit level.   There are other issues 
to think about
two, like if you had more than one drive mounted, then tar would include 
the

contents of all mounted drives in the archive.

It is not necessary to put /usr/local/lib/* in the PATH.  The gcc in

Why does the locate command not find any gcc files that I have

It's possible your slocate database isn't up to date. run "updatedb".


crtbeginS.o does exist in the

Probably because the gcc you are using is /usr/bin/gcc.  Which looks in
/usr/lib/gcc-lib for the support files.

Try typing:

No it was from /home//usr/local directory

Would that make a difference?


It might.

This gcc command is being called during compilation of a library. I 
don't think I can modify the source code for it?


You can probably change the makefile, but I dont' think you'll need to, 
if GCC_EXEC_PREFIX

$ORACLE_HOME, I would change sys_include to only include that directory 
and not
any of the gcc ones.  Another option might be to remove gcc from your 
system completely.


Again, I'm only guessing.  I would have to read up on the compiler more, 
before I could
give a qualified answer.  If you post relevant links, I will see what I 
can find out.
