National ADSL company uses Thompson ADSL modems with wireless with 
custom password for each unit, if I got that correctly. It is definitely
not OEM password. I guess they used different passwords to prevent 
others hacking into router via wireless.

And they use different password for actual PPPoE connection. First 
(Huawei) modems they used even lacked the option to change or even see 
PPPoE username and password.

Could be newer DSL technology, or could simply be some sort of caching
and compression system that you have to use Windows client software to
take advantage of it.  But it sounds like new DSL technology according 
to the press release and sales site.

And maybe double-check that the line was actually upgraded?

Nope. It may be the default setting password that the OEM assigns. Ask
your ISP what the password is. For my old Westell, it was something like
password, something dumb. I got in and changed it, of course. Resetting
the original settings, including the password, was push a button.

The speed increase is possible, for sure, as long as you're close enough to the 
DSLAM.  We have an 11Mb/s DSL option here, but it does require improved 
hardware (ADSL2+).

The modem wants a password for management; you'll need to google for the 
default modem password for that particular model to be able to start management 
without the CD.  Using the modem manufacturer's CD allows an easy setup for 
Windows, typically, and walks you through the install, but it's very rarely 
actually required, unless it does have a firmware update on it.

Actually, the modem's web-page is at 192.168.1.254 ,

No. I was rung one day by a lady at my ISP (Eircom),
who told me I had been chosen as a recipient of their new "Ultimate" system,
which would increase my speed from 5Mb/s to 14Mb/s,
at no extra cost!
Apparently this was not available to any old customer;
I had been specially picked out for the privilege.
I can't think of any reason why I should be picked out,
except that I always pay my bills.

(I have been with them for ever, and remember being told by them long ago
that scientists had proved it was physically impossible
for traffic down a telephone line to exceed 300b/s .)

It is PPPoE, I think.
I'll try changing the MTU sometime, and see if it has any effect.
Thanks for the suggestion.

It might be a firmware update, or a download accelerator (which requires ISP 
cache support) installer.

Something like NetZero, that uses special compression between the cache 
provider and the consumer that makes things seem to load faster.  In which case 
you have to have Windows to run the client side of the compressed cache stream. 
 This also interacts with the browser cache, and actually resizes typically 
too-large images down, something like what a PDF creator would do for embedded 
images to go to the actual PDF dpi setting.

Or, assuming that it hands out a DHCP address with a default gateway 
(and the modem/NAT unit is acting as the default gateway):

a) Look for the default route (indicated as the line starting with 
0.0.0.0 for IPv4)

# route -n
0.0.0.0 192.168.0.1   0.0.0.0 UG

b) Look at the dhclient.leases file.  This can be hit or miss, depending 
on whether you can find the proper section.  Other distros put it in a 
slightly different location.

/var/lib/dhclient/dhclient.leases
lease {
   interface "eth1";
   fixed-address 192.168.1.186;
   option subnet-mask 255.255.255.0;
   option routers 192.168.1.1;
   option dhcp-lease-time 3600;
   option dhcp-message-type 5;
   option domain-name-servers 192.168.1.1;
   option dhcp-server-identifier 192.168.1.1;
   option domain-name "lan.example.org";
   renew 3 2009/4/8 11:57:39;
   rebind 3 2009/4/8 12:21:03;
   expire 3 2009/4/8 12:28:33;
}

c) Or the "ip" command.

$ ip route list
default via 192.168.1.1 dev eth0  proto static

(Guessing about IP addresses gets harder in a few years once IPv6 
finally goes mainstream.)

Do you know what kind of change this was supposed to be?  If you are 
running DSL with PPOE it might have been a registry tweak for windows to 
reduce the MTU.  On Centos you can just put MTU= in your ifcfg-eth? file 
with the value you want (I've seen 1492 suggested for this).  If it is a 
cablemodem it doesn't make much sense to need to do anything under windows.

It is *not* true. The only thing that I can imagine that software doing is
setting it up for Windows, and Windows only.

Right, I just looked it up, and I see it's an ADSL modem. Look at your IP
address, and I'll bet you're 192.168.0.x, or 192.168.1.x. Whatever it is,

The machine is running CentOS-5.6 .
The modem is running fine, but my speed has not been improved threefold,
as promised.
In fact the speed is identical to the previous modem, as far as I can tell.

I find a Windows dual-boot quite useful on many occasions,
eg if some card or other device does not work under Linux it is worth seeing 
if it works under Windows.

Also, if I have to call my ISP (I did once, when the line outside 
was damaged in a storm), it is more or less obligatory to be running Windows
during the visit.

I've been running Unix for 30 years, having graduated to Linux from Minix.
I guess my philosophy is closer to Linus Torvalds than Richard Stallman.

Actually I always leave or install a small Windows partition
on my Linux machines.
I find that I occasionally need them, eg when updating firmware.

I don't have the religious objections many Linux users have.

In this case, when I go to the modem web-page (192.168.1.254)
it asks me to insert the CD "for further information".

As I mentioned, I had already installed CentOS on a USB key,

The modem is a ZyXEL P-660HW-T1 WiFi modem/router (made in China).
It works fine, but my speed is not 3 times what it was before!
My ISP (Eircom) claims I have to run the configuration utility
on the Windows CD to get "up to speed".
I doubt if this is true, but I guess I ought to try it.

I assumed that was what was meant,
and put copies of this file everywhere I could think of:
in the same place as the DVD, in an images directory there,
on the /boot partition, etc.
But none of them satsified the installer.

I thought it slightly silly that the installer does not say
exactly what file it is looking for
(and where it expected to find it).

In my experience this is not uncommon in Linux programs;
you are told that something is missing,
but precisely what is left to the imagination.
Presumably the program must know exactly what it is looking for,
so I don't understand why the information cannot be passed on.

Thanks.
Actually I did know about these, though I've never used them.
I misunderstood the poster; I thought he/she was pointing to a file
that I should have downloaded.

In fact there was a Debug button to press when the process failed.
I looked at the output of this, but it didn't really help.
It seemed to say that the installation was looking for
a file in /dev/sdb7//ext2/ where /dev/sdb7 was the device holding the DVD.

I guess that, as pointed out, this could be something on the 2nd DVD.

On the other hand, I googled for the error message,
and it seemed several others had had the same problem.
That was why I asked if anyone had actually succeeded
in installing CentOS-5.6 from the hard disk.

Reading this, I'm thinking still more about the bigger picture, there. I
didn't see the start of this thread - is this a home system? If so, using
WinDo$e is pointless, if you're running Linux, unless you're running Linux
in a VM under WinDoze. Lessee, a quick google finds me this:

You could ask someone to bring their Windowz laptop, set it up and you

You could put everything on an 8G USB key.

?? What kind of modem? Linux handles almost everything. Certainly, I
didn't need to install WinDoze to work with the DSL modem I got from
Verizon.

There are several consoles available during install and boot.
If you hit Alt+F1, you'll see the "regular" install/boot text.
If you hit Alt+F2, you'll see debug outputs of portions of the
install/boot process.

Alt+F3 gives you another console from which you can e.g. run various
tools (dmesg, ps, df, fsck, etc).
John Doe (not his real name) suggested looking at these other consoles
to see what had been printed out during install/boot.

I suppose there could be something relevant on the 2nd DVD,
although the first has been sufficient to install in 3 other ways:
1) via HTTP from another machine on my home LAN;
2) after copying the DVD-1of2 to a USB stick; and
3) it was also sufficient on a machine with a DVD drive.

I'm not sure what this is.
I copied everything in isolinux and images on the DVD
in several places.

Now I have to work out how to install Windows on the machine,
but I daren't ask about that here ...
I need it because my ISP claims to have tripled the speed
of my supply, but says I have to run a Windows CD
to setup the modem he has given me.

The "image #2"... what about 2of2?
 Did you check the debug consoles (alt-Fx)?

Yes: 
md5sum -c md5sum.txt.asc
CentOS-5.6-x86_64-bin-DVD-1of2.iso: OK

As I said, I installed CentOS-5.6 by http without problem.
I've also installed it by netinstall and on a USB stick.
But I haven't been able to install it from the hard disk, as I said.
I'm pretty sure it is a bug in the installer program.

Strange, I install it from the DVD.iso to VMWare images a couple times a month, 
haven't seen that issue.

Once a new release gets approved for production, I copy the contents of the 
DVD.iso to our PXE Boot server,
and install production machines from there. 

(FWIW, I have not installed in onto real hardware, from a real DVD, in a couple 
years now..)

Are you sure your DVD matches the checksums?

[CentOS] hard disk install failure

[Timothy Murphy]

Has anybody successfully installed CentOS-

I tried (several times) installing CentOS-5.6 from a hard disk,
and each time it failed after installing all the rpms,
with the warning "The installation has tried to mount image #2,
but cannot find it on the hard drive."

When I pressed the Debug button one time after the failure,
it seemed to say that it was looking for the file in /dev/sdb7//ext2/
(/dev/sdb7 being the site of the DVD ISO).

But I'm not sure what "image #2" is? Or where it should be put?

Incidentally, I started by copying isolinux/vmlinuz and isolinux/initrd.img
to the the directory CentOS-5.6 in the /boot parition
of a working linux (Fedora) system, and adding the stanza

title CentOS-5.6
root (hd0,1)
kernel /CentOS-5.6/vmlinuz repo=hd:/dev/sdb5:/
initrd /CentOS-5.6/initrd.img

The repo option was ignored, and I was asked if I wanted to install by FTP,
from Hard Disk, etc.

In the end I installed by http from my web-server, after
mount -o loop CentOS-5.6-x86_64-bin-DVD-1of2.iso /var/www/html/
on the server .
This worked faultlessly, and seems to be by far the easiest way
to install CentOS or Fedora if a local web-server is available.
