Re: IPv6 support in old (2.4) kernels
Hello,
I don't have direct answer to your questions as I don't know much about
the 2.4 kernel code.
However, I just want to give these four comments about IPV6 in 2.4 Linux kernel:
1) Also in the latest 2.6 kernels you cannot rmmod ipv6 when it is
configured as a module, although work is done to enable this in the future.
So you can ignore or not treat too seriously this
unloading bug when IPv6 is configured as a module note about the 2.4
kernel you mentioned
2) As far as I know, most test suites for IPV6 are not compatible with
the 2.4 kernels (for example, TAHI Conformance Test:
http://www.tahi.org/conformance/).
I did not check this point though.
3) The 2.4 kernel does not have any IPSec support (not for IPV6 ; I think that
also not for IPV4).
IPSec is mandatory according to the latest IPV6 spec and is
optional in IPV4 spec (although most operating systems, including Linux and
OpenSolaris had implemented it also as part of IPV4).
See, for example, in RFC 2401, (Security Architecture for the Internet
Protocol),
although it is **not** mentioned in your list.
from rfc 2401:
...
...
10. Conformance Requirements
All IPv4 systems that claim to implement IPsec MUST comply with all
requirements of the Security Architecture document. All IPv6 systems
MUST comply with all requirements of the Security Architecture
document..
..
..
4) The only tunnel you have in 2.4 IPV6 is sit (IPv6 in IPv4 tunnel).
At least in the
link for 2.4 code you mention in your mail. (maybe it does exist in
newer versions of 2.4)
You don't have the ip6_tunnel (ip6tnl) which is IPV4 or IPV6 in IPV6.
(Though this is relatively easy to implement, based on the 2.6 implementation)

Rami Rosen

Hi folks,
I suppose there are some people here who for one reason or another still run
kernel 2.4 on servers or embedded systems and are willing to admit to it.
Can anyone tell me how well kernels circa 2.4.19 (or later) support the
*current* IPv6 specification? I see IPv6 support in the code
(http://lxr.linux.no/linux-old+v2.4.19/net/ipv6/) which is marked as
EXPERIMENTAL and carries warnings in the configuration, but it looks like
this is associated with some unloading bug when IPv6 is configured as a
module (http://lxr.linux.no/linux-old+v2.4.19/net/Config.in). The same
warning appears in 2.4.31 which is the last 2.4 in LXR at least.
Suppose I will be happy to compile IPv6 into the kernel (not as a module) -
I am still interested in how well 2.4 supports today's IPv6. More
specifically, after some research I have come to a conclusion that I am
interested in assessment of 2.4 support for (at least) the following:
* IPv6 (RFC2460)
* ICMPv6 (RFC 4443)
* Neighbor discovery for IPv6 (RFC2461)
* Path MTU discovery for IP6 (RFC1981)
* Address configuration - either SLAAC (RFC2462) or DHCPv6 (RFC3315)
* IPv6 addressing architecture (RFC4291)
* Scoped address architecture (RFC4007)
* Unique local IPv6 unicast addresses (RFC4193)
* Multicast listener discovery (MLD) for IPv6 (RFC2710)
Can anyone shed light on the above (any V's or X's will help, as will don't
even think of it)? Is anyone running 2.4 in IPv6 environments? How
mature/up-to-date is the support?
If IPv6 is a requirement, does it absolutely mandate moving to
2.6.{latest,recent-enough} or will 2.4 be possible? Is there any version of
2.4 from which IPv6 support is markedly better than in earlier ones?
I have seen http://www.tldp.org/HOWTO/Linux+IPv6-HOWTO/ and
http://www.deepspace6.net/docs/best_ipv6_support.html, among others. It is
not clear to me how updated the info related to old kernels is. If anyone
knows that I can trust these documents that will be great.
Let's not go into the question why 2.4 is important, OK?
Thanks a lot in advance,

samba, CUPS and Windows
Hi, I'm looking for a configuration to print from Windows to my new Office Jet which is connected to my Linux box. I can use the CUPS driver, but I prefer to use the native HP drivers. Only thing is that I didn't find any explanation of WHAT to put in /etc/samba/drivers, why do i need to work with user level in samba in order to make cups play nicely with windows, etc.. Does anyone have a good config sample which prints from windows using cups and the native linux drivers?

The first question I have is does it work from Linux? What happens if you print a file with a2ps? For Windows XP use the Apple LaserWriter Plus v38.0 driver and make sure to go into properties, device settings, an turn off send control d before each job (you can also turn it off for after too, but I don't think it matters).

He's looking for a (dummy) user friendly English/Hebrew Linux version. Can someone please come up with a suggestion, Well, hoping that this doesn't start a distribution flame-war, I'd give my recommendations. My favourite distribution is Mandriva Linux ( http://www.mandriva.com/ ), and as a general rule I'm very happy with it. It has bi-annual releases, but I'm using Mandriva Cooker which is what is the bleeding edge that's going to be the next version. Mandriva aims to be suitable for beginners, and as far as I can tell it generally is, but obviously I'm not a beginner by a long shot. Hebrew in Mandriva apps works very well, but I'm using an English interface. Other popular distributions for beginners include Ubuntu. I'm using it at work, and I guess it's OK, but I still prefer Mandriva. Ubuntu and Mandriva use different package formats (.deb vs. .rpm) and so packages from one will not work natively on the other. There's also MEPIS which is another .deb-using distribution aimed for beginners. Fedora is another .rpm based distribution, endorsed by Red Hat Inc.. I worked with it at several workplaces. It's not too bad, but has some warts. CentOS is an open-source re-packaging of Red Hat Enterprise Linux, which in turn is taken from Fedora, but with long-term support offered. I haven't worked with CentOS extensively. Note that all the distributions I mentioned are also suitable for many experts so they can grow with you. There are many distributions that are much less suitable for beginners, like Gentoo, which is source-based, and Archlinux, which requires explicit tweaking for everything, and Slackware which is relatively minimalistic. I wouldn't recommend to start with them. (They do often provide more flexibility and/or power, but that's besides the point). Can you expect your son to be able to contact an expert for help in case he has some trouble? Is he net-savvy enough to search-the-web and ask in forums and IRC channels? I recommend having either for both Linux, but I personally don't think the situation with MS Windows is any better in this regard.

Re: samba, CUPS and Windows
Well, I played a bit with it a bit more. I managed to install it with the IPP (http://servername:631/printer/ etc), but that has caused my Windows Print spooler service to bump 99% CPU usage (I checked, nothing is in C:\WINDOWS\System32\spool\PRINTERS). So, I'm going to put the printer connected to a windows machine and share Linux with it. This at least will give me the functionality that the Linux driver doesn't have (setting the buttons, voice-answering, faxes etc..) Thanks for the help!

Well, see for instance /etc/udev/persistent.rules on my Debian Etch

KERNEL==sg*, ATTRS{type}==8,ENV{ID_SERIAL}==, \
IMPORT{program}=scsi_id -g -x -s $devpath -d $tempnode

IMPORT{program}=scsi_id -g -x -a -s $devpath -d $tempnode
(sg being conventional generic SCSI device names).
So udev is not limited to usb devices only. It owns the entire /dev
directory.
From the udev-faq:
Q: Can I use udev to automount a USB device when I connect it?
A: Technically, yes, but udev is not intended for this. All major
distributions
use HAL (http://freedesktop.org/wiki/Software_2fhal) for this, which
also
watches devices with removable media and integrates into the desktop
software.
So, it seems that HAL would be the one taking care of the removeable
media in
the burner.
The way I understand this, HAL (Hardware Abstraction Layer) provide the
information and sends triggers over a data bus to other programs when it
changes. It also maintains a database of current devices.
Udevd is just one subscriber to these messages and this is how it finds
about new/removed devices, but both HAL and udevd are not limited to
removable media - see an excerpt from the output of lshal on my desktop:
udi = '/org/freedesktop/Hal/devices/acpi_CPU1' (i.e. HAL lists the CPU
itself, which is not dynamically changeable on this system).
