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.

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..)

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.

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. (The machine I was trying the hard disk install on- an HP MicroServer - has no DVD drive.)
Did you check the debug consoles (alt-Fx)?
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.
Did you check the debug consoles (alt-Fx)?
I'm not sure what this is.
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.

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.

Try a minimal install. That won't hit the 2nd dvd.
Actually no installation I have done (including one with practically everything chosen) has ever required the 2nd DVD.

You could ask someone to bring their Windowz laptop, set it up and you are done. One you set it up like they want, you are not going to need that CD again, at least for a while.
And most xDSL modems have nice web GUI, CD's are mostly used as idiot-proof measure with nice colored setup program.

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: http://www.centos.org/docs/5/html/5.1/Deployment_Guide/s1-network-config-xdsl.html.

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.

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 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.

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.

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.

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.

Digging through their FAQ site:
Do I need to change any equipment or settings on my computer?
No, you don't need to change anything. Your modem will pick up the new speed automatically. A very limited number of customers may be required to 'turn off' and 'turn on' their modem for the upgrade to take affect.
Maybe the Windows CD needs to install new firmware.
How will I know that my line/broadband was upgraded?
If you are an eligible customer eircom will send a letter to you in advance notifying you that you will be migrated to the Next Generation Broadband product in the near future.
Alternatively, if you visit www.eircom.net/ngb and go to the: "How Can I Get it?" section. Then enter your eircom telephone number and account number and you will be informed if your broadband has been or is scheduled to be upgraded to a Next Generation Broadband product.
And maybe double-check that the line was actually upgraded?

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. As Henry IV said, "Paris is worth a mass".
And most xDSL modems have nice web GUI, CD's are mostly used as idiot-proof measure with nice colored setup program.
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".

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.

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, try pinging 192.168.[0 or 1].1. Whichever it is, pull up your browser, and point it to that IP, and you should be at the modem's web interface, and you can go from there.

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.

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.)

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.
