Hi
My problem hasn't been solved yet. I returned the directory name to what
it was before (2.2.16), but still don't know where to get the module
files for my new kernel !
Thanks

Is FreeBSD Linux ?
I'm trying to figure out FreeBSD. I'm currently using RedHat 7, and I'm
happy with it.
I read that FreeBSD uses Mach 3.0 kernel. Correct? Or does FreeBSD use
the Linux kernel? What is Mach? How is Mach related to Linux? What about
NetBSD or OpenBSD?
Can software written for Linux run on BSD systems?
Is Linux Unix? What's the difference between Linux and Unix?

I have a Redhat Linux 6.0 box with two nic's: eth0 and eth1. The "eth1" is
the internal interface and "eth0" is the external. For eth0 all I did was
put three lines in "/etc/sysconfig/network-scripts/ifcfg-eth0" to connect to
DSL (via TELUS, BC, Canada):
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
The nameservers automatically get stuffed into /etc/resolv.conf by the ISP
when the IP address is assigned. That's all I had to do. Works great.

Subject: Kernel NFS problems...help
Date: Wed, 31 Jan 2001 20:19:22 -0800
Greetings:
I have a small network at my office composed of three machines - one
server and two clients, all running Mandrake 7.2. All are dual-boot
boxes (Linux and Windoze 95). The server contains an old DOS-based
database application and its associated data files, which I need to
access from the client machines (I run it under DOSEmu). To do this, I
need to be able to mount two VFAT directories on the server from the
client boxen. I also have a USB Zip-250 drive on the server which I use
to back up the data at the end of the day, and a USB scanner which I'm
trying to get running with SANE.
To cut to the chase: Kernel-NFS appears to be broken in all kernels
since 2.2.17; this is the "stock" kernel that comes with Mandrake 7.2.
When running this kernel on the server, I *can* NFS-mount the VFAT
directories on the client boxen. With every subsequent kernel since
(2.2.18 and up, through 2.4.1) I cannot - I get an error message stating
"Permission denied by server".
I suppose I could simply live with the 2.2.17 stock Mandrake kernel,
except for the fact that the USB interface doesn't work with it at all.
This is not a hardware-specific problem. I have noticed the same
problem on my home network; running RedHat 7.0 with an old
custom-compiled 2.2.16 kernel allows me to share MP3 files currently in
a VFAT directory, whereas with 2.2.18 and up - same problem: "Permission
denied".
When I compile these kernels, I statically compile in NFS support
(including the option for v3 support in the 2.4 series).
I have looked all over Usenet and haven't found an answer to this, and
have even submitted a bug report to Trond in Norway (recently; haven't
heard back yet).
Is there something obvious that I'm missing here or is kernel NFS really
broken in the 2.4 kernels? If the latter is true, is there a
workaround, and are the developers aware of the problem? Unfortunately,
I have to leave these files in VFAT directories for now.
Thanks in advance; if anyone can help, please reply via e-mail as well,
since I don't get onto Usenet too often.

Incorrect. Mac OS-X uses some variation on Mach, but FreeBSD is a
monolithic kernel of its own.

No. It is a monolithic kernel originally based on BSD 386, and hacked
considerably from there.
> What is Mach?
Mach is an operating system kernel that came with models for threading
and multiprocessing that was built at Carnegie Mellon University. It
was of great interest amongst Unix implementors until Microsoft hired
the head of the project to be lead researcher at Microsoft Research.
Digital and NeXT used early versions as the basis for their
monolithic-kernel Unix implementations; later versions of Mach were
more oriented to microkernel work where the OS would be implemented as
processes running atop the microkernel.
> How is Mach related to Linux?
Hardly at all. There is a MkLinux project that runs the Linux kernel
atop Mach; this was used to support some older Apple/PPC hardware, but
is not in _widespread_ use.
> What about NetBSD or OpenBSD?
NetBSD was the "split" from the BSD386 project that sought to build a
BSD system that would be portable, running on many hardware platforms.
OpenBSD was a "split" from NetBSD; Theo De Raadt did a security audit
of NetBSD, and had a lot of changes to propose. He and the existing
NetBSD developers did not get along well, so there was a
not-entirely-amicable parting of ways where he started the OpenBSD
project to provide a "more secure" variant of NetBSD.
> Can software written for Linux run on BSD systems?
No. Software that is specifically "written for Linux" won't work with
other operating systems.
However, people seldom truly produce software "written for Linux,"
Conspicuous exceptions being GLIBC and init.
People generally produce software "written for Unix," and that is
likely to be able to function on the BSD variants.
FreeBSD has a pretty sophisticated ABI emulation system that allows
running binaries compiled on Linux on FreeBSD. With NetBSD and
OpenBSD, it is somewhat more likely that you would need to recompile
the software to make it run there.
Software of questionable integrity may have environmental dependencies
of expecting files to be in particular locations true only for a
specific Linux distribution. Such applications are not likely to work
well on other than the developer's Linux distribution, so the
compatibility problems can bite people running Linux as much as they
would bite BSD users...
> Is Linux Unix? What's the difference between Linux and Unix?
Linux generally speaking has the "Unix nature," but is not formally
branded as Unix. That requires running through a certification
program and paying royalties to, um, "whomever it is that owns the
Unix trademark today."

Subject: NFS broken with 2.4.1?
Date: Wed, 31 Jan 2001 20:39:56 +0000
Recently installed 2.4.1 kernel on a RH 7.0 box and got the following error
message when attempting to mount an NFS share (NFS server services were not
compiled into the kernel, as this box will be client only):
NFS: NFSv3 not supported
nfs warning: mount version older than kernel
Does this mean the new kernel does not support earlier versions of NFS?
How will this effect an environment with older versions of Linux/NFS
running? Can this be fixed?

You should have already had a directory /lib/modules/2.4.0, after running
"make modules" and "make modules_install". Do you have a new enough
version of modutils installed? See Documentation/Changes in the kernel
source code.

Red Hat has an updated rpm version on it's errata page
where you can download rpm-3.0.5-9.6x.i386.rpm.
I'm sure Mandrake has a similar upgrade on their site.
(If not, just use Red Hat's)

The Linux kernel only has vestigal support for ACLs, and the fact that
NFS v2 doesn't support ACLs means that people have limited interest in
it if they need to share filesystems.
In effect, support of ACLs will require the combination of:
a) The kernel VFS supporting it well;
b) Filesystems supporting good places to store ACL info;
c) Network filesystems supporting ACLs;
d) Useful userspace tools to manipulate the ACLs;
e) Looking forward, support by packaging tools like RPM/dpkg for ACLs.
The FS support issue _is_ really a small part of it...

No, it means your nfs client does not support v3, only v2.
Either make the server v2, or use a v3 client.
The message from mount is just telling you that you have a new
kernel. Ignore, or make a new mount executable.

If that is true (and I don't know) use unfsd instead. I assure you in
works fine in 2.2.18 and 2.4.0.
