It's a Dell BIOS with the BIOS configuration password set.
Use Alt-P to go through the BIOS configuration pages, use
the arrow keys to go down to the configuration password
and enter the password.  Then use Alt-P to go back to
the boot order page and alter the boot order.

If you don't know the password then you're in for a ride.

I'm afraid that after checking those that what you have is

Well, using the t1unmac program from the t1utils package I've
managed to convert them to Postscript Type 1. I still need to
convert them to Truetype or OpenType.

Anyone?

That just shows you who the clueless business people are.
If your website isn't set up for 28.8/33.6Kmodem users, then you are
loosing an awfull lot of customers.

i didnt use the words "living in the past"

my comments was that the internet has moved forward.

by that i mean, most content is now aimed at higher
speed connections. there is more moving stuff on webpages,
more images etc.

things that are trivial on dsl etc are something of a commitment
on dial up.

that is all.

Thanks to all that replied, the file is well and truly split!

I used Peter's awk solution. Very elegant! That one will be filed under
'useful'.

For the sake of the  archives, I didn't find a solution to the segfault
in csplit, despite forcefully reinstalling the latest coreutils RPM.
That box will be retiring soon so I'm not too worried about it.

Re: [SLUG] smtp troubles

[Howard Lowndes]

This problem has been solved.  It is a buggy old version of Domino that
doesn't send a correct FIN response packet as the second part of the TCP
connection teardown, thus leaving many connections in CLOSE_WAIT state; I
discovered an IBM paper about the problem.  RH7.1 (the earlier opsys) was
more tolerant of this problem than the current opsys (FC5).  The solution
is that the client has been told to put his hand in his pocket and upgrade
his Domino server software.

It depends.

If you've a jack-of-all-trades, or aren't big enough to hire separate
people, then your one person is it, they do the installs, the upgrades, the
DB"A", and they write the apps.  I've been there.

If you're a bit bigger, the chances are you've got someone who herds all of
your machines (desktops mostly, probably) and they'll probably install,
tweak, and patch the stack, and there'll be a web monkey who puts the
software together.  Either of one of them might do the DB stuff, depending
on who has the skills.

As you get bigger, you'll probably keep much the same structure.  At one
place I know, there's a team of two or three admins who keep all of the
machines together and do the underlying DB work (create DBs and users), and
then the dozen or so developers put the apps on top and maintain the DB
schemas.

At some point, you'll probably have enough databases to justify having
someone specialise (even if it isn't their entire job) in wrangling the DBs. 
This is especially true if you've got Enterprisey DBs like Oracle or DB2,
because they need a lot more care and feeding than PgSQL or MySQL.

If you're a government department, then you'll probably have totally
different contracting organisations handling the server maintenance and
application management, and to get an admin change done, the developers will
need to lodge a ticket in the other company's ticket tracking system and
wait a week for it to be actioned[1].  You think I'm joking, but I'm not --
buy me a beer and I'll tell you stories that'll make your hair fall out (or
grow back, if you're didymo).

So, to reiterate my original comment, "It Depends" -- on how many people
you've got, what their skills are, what you're actually trying to
accomplish, and whether you're a byzantine bureaucratic organisation who
exists primarily for the purpose of sending normal people insane.

Excuse me while I reach for my awk hammer again.

zcat dump.sql.gz | awk 'BEGIN { outfile = "preamble"; x = 1 }
$0 ~ /^CREATE TABLE/ {
close(outfile); x = x+1
outfile = x"-"substr($3,2,length($3)-2); }
{ print $0 >> outfile }'

Will give you everything beforethe first CREATE TABLE in a file named
preamble, and all of the other tables in file names numbered
sequentially with the table name appended. I figure that keeping count
will help assemble the tables in the same order as in the original file.

Have tested quickly one a dump from one of my MySQL databases and
everything seems to be kosher. But check your own data before taking my
word for it. :-)

[SLUG] Advice on booting a Dell Inspiron 2100

[Ken Caldwell]

Hi All,

I have been lent a Dell Inspiron 2100 to play with but it won't boot.

It has a 700 MHz Pentium III CPU, 128 MB RAM, a 20 GB IDE hard drive and
an external IDE CDROM.
The computer originally had (has?) Windows ME installed.

On power up it runs through a self test and then stops with a blank
screen with just a single hyphen or underscore showing as though there
is no operating system installed.

The boot order according to the BIOS setup program is

1 Removable devices (there are none)
2 Hard Drive
3 CDROM
4 Network

The BIOS does not seem to allow changing the boot order. There is a
message which reads;

All items on this menu cannot be modified in user mode. If any item
require changes, please consult your system Supervisor.

Are there any sluggers with experience of these beasties who can tell me
the magic needed to change the boot order? I am hoping that if I can put
the CDROM before the HDD I may be able to boot from something like the
System Rescue CD or similar.

TIA

[Matt Moor]

This isn't a SLUG event, but we on the committee thought it might be of 
interest.

Hi,

Just want everyone to know that there will be an "InstallFest" for SUSE Linux
Desktop 10 at Novell on the 16th of May in Sydney, 5.30PM sharp.

goto www.snug.net.au
for more details.

It is a great opportunity to talk to Novell engineering about SUSE 10, also
great opportunity to mingle with other users. Talk to the Novell about the up
and coming new "Cool" features of the desktop including "Beagle", XGL, compiz,
etc. and how it will affect your computing life.

The meeting is free and there is drink and snack food - all welcome to come.
Bring your laptop (we can't cater for PCs) and have Novell guide you through an
install. Oh and the laptop must be able to read DVDs - read the recommended
hardware list on the snug website.

There are giveaways and a luck door prize - a really cool backpack

Hope to see you all there

Csplit seems to do the trick, although it's segfaulting on me. Here's an
strace:

open("xx05", O_WRONLY|O_CREAT|O_TRUNC|O_LARGEFILE, 0666) = 4
fstat64(4, {st_mode=S_IFREG|0666, st_size=0, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xf6e96000
read(3, "nything? Come on...Tell me what "..., 3074) = 3074
read(3, "758374),(44,97,4575,15912,\'Sutek"..., 8192) = 8192
read(3, "),(87,154,34832,42439,\'Perfectio"..., 16384) = 16384
brk(0)  = 0x9b45000
brk(0x9b68000)  = 0x9b68000
read(3, "by http://www.inthemix";..., 32768) = 32768
brk(0)  = 0x9b68000
brk(0)  = 0x9b68000
brk(0x9b58000)  = 0x9b58000
brk(0)  = 0x9b58000
read(3, " the migration of 19 white pages"..., 65536) = 65536
mmap2(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xf6e55000
read(3, "617,\'Optimus Rhyme\',\'\',\'Untit"..., 131072) = 131072
munmap(0xf6e55000, 266240)  = 0
mmap2(NULL, 528384, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0xf6dd4000
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++

Any ideas what could be broken? Csplit manages to chop into few files
then segfaults.

Thanks,
Rob.

Rachel,
In my experience (mostly a very large national enterprise with a
well-established IT group) you're right, it's the (Unix/Windows/...)
system administrators who undertake such tasks.

I once found myself pursuing an almost identical question, but along
network lines instead: Who does the network configuration and
administration of your server infrastructure? The network administration
team or the system administration team?

I've seen very few cases where it isn't the system admins that do the
network configuration of the server infrastructure, yet nearly all
network reconfigurations are prompted as part of projects initiated and
owned by the network administration team.

Who manages and configures your DNS? Your resolv.conf? Is name
resolution an application service or a network service?

The system adminstrators usually end up performing an entirely menial
task almost completely under the direction of the network
administrators. Why?

Allowing the network admin team to change the IP address of an ethernet
port on your server usually requires giving the router jocks your root
password, something you'd never do.

I've found that the allocation of responsibilities has generally fallen,
somewhat pragmatically perhaps, along the lines of 'who can actually do
it?' ie, along identity/access-control/authority lines. If you have the
root password you can install and configure software and hence usually
end up doing it, because to allow others to do it necessitates providing
them with the very thing you preciously preserve: your control over the
relevant piece of infrastructure.

I have a case in mind that further illustrates the potential truth of
this: mainframe environments. In mainframe environments the system
security and rights allocation mechanisms are usually sophisticated
enough and fine-grained enough that you can grant the network
administration team sufficient rights for them to undertake their
relevant activities, without giving them rights to completely
reconfigure everything. In these environments the division of labour is
often more rational.

Virtual machine environments will see a shift I think, especially in the
scenarios in which you're most interested: application configuration.
When it becomes more common for individual or clusters of related
applications to be hosted in virtual hosts rather than within the same
single shared operating system instance it will be easier (read:
safer|more likely) for responsibilities within a particular virtual host
to be shared with the people actually responsible for the applications
running within them. The application support teams may be given more
power over their applications and the system administration team may
voluntarily relinquish the exclusivity of rights that they currently
preserve.

regards
Terry

there could be various reasons for this. e.g. if there are indexes in 
the table-structure, you could speed up the the insert with dropping the 
indexes first, importing the data and create the indexes after insert 
again. this is because ususally autocommit is turned on and the indexes 
are updated after each commit. and recalculation of indexes for a bunch 
of rows is much faster than for each row.


if you are creating the dump by yourself, you could use the "-T" option 
of the mysqldump-tool. this will create separated files for data and 
create. check also "load data" for how to import the files generated.


how about splitting an sql into smaller chunks, sorry, i have no idea.

I've never used it, but I think csplit is what you are after.

If the dump is of the format (CREATE TABLE ... INSERT, INSERT, INSERT)
for each table, awk would be a nice candidate, but I know v.little awk.
Perl or Python should be able to handle it in about 10 lines of code.

[SLUG] Splitting MySQL dump

[Rob Sharp]

Sluggers,

I've got a large (2.6G) MySQL dump containing extended SQL inserts which
I need to import onto a server.

Server is FC2 based and we're running a very old MySQL - 4.024

Thanks in advance,
Rob.
