Hi there,
you have seen it ? Thats funny because that screws microsoft guid
contained in word documents. I think they are using the mac to
"personalize" your documents. :-))
Ok, but when they are two macs how does it behave when they are on the
same network ? And I guess the vendor of the identical macs is in breach
of contract with the organization which hands out the mac numbers.
What do you think ?

Michael

To my knowledge some advanced cards as well as some UNIX workstations
allow a user to change the MAC through software. Dunno the reason for
this, but in the case of where some software uses the MAC as part of its
licensing, it saves you having to relicense if the card is replaced :)

Bash is needed to execute various scripts that play a role in the build. The
versions of tools used in the build do make a difference; you have to have a
sufficiently great version of make, bash and so on.

I seem to believe, perhaps incorrectly, that some adapters have addresses that
can be reprogrammed from the host machine.

Fair enough.
The answer is very simple - the mail app sends what it gets. Give it
plain text, it sends text. If you want to send html, send it html.
echo "<html> (etc, etc) </html>" | mail ...

Thats what I guessed. Thing is the guy from SuSE recommended not using
bash204. Bas204 is imho latest. I also have more compiler rpoblems if
using this version. Now I am back to 203, that helped a lot.
Question is, what is wrong and why does something depend on it in 204.

I can't think of that. Since the maufacturer takes responsibility for
the correctness and uniqueness of the mac in the card.
I only can think of special adaptors for testing purposes, and think
normally the mac's are hardcoded in there to prevent changing. The idea
was to have a unique possibility to adress a specific adaptor,
worldwide.
Please if I am wrong, tell me otherwise since I am no expert when it

>From what I understand, if you want to run the old DECNET protocol,
you have to be able to set the MAC address yourself - DECNET uses the
MAC address for routing purposes. A bad idea, I don't doubt, but
that's how it works.
It's fairly common for Ethernet chips to be able to read their MAC
address from an on-card PROM/EEPROM chip, or to accept them
programatically from the driver or BIOS, or both. This can allow for
a cost reduction in embedded-system and on-the-motherboard
applications. You can eliminate the need for a separate EEPROM, by
having the BIOS or driver do the initialization based on a unique MAC
address programmed into the system's main ROM/EPROM/flash chip or
stored in the auxiliary storage bytes in a battery-backed clock chip.
In these cases, the responsibility for making sure that the interface
has a globally-unique MAC address still exists - but the
responsibility is implemented at the system level rather than within
the chip or card.

Hi,
What does this link error mean and how do I fix it?

I tried find / -name " crt1.o" -print and it found nothing. I installed

Hi; could you post a summary of what you did to make it work? Perhaps
a pointer to the patches?
So far, I've discovered that you need to enable the "experimental"
interfaces for the kernel config and then enable the nfsd kernel
module. Just running NFSD doesn't cut it any more.
Now, when I run /etc/rc.d/init.d/nfs start, I get this output:
Starting NFS services: [ OK ]
Starting NFS quotas: [ OK ]
Starting NFS mountd: mountd: couldn't stat /var/lib/nfs/etab
[FAILED]
Starting NFS daemon: [ OK ]
What is this /var/lib/nfs/etab file, and why should I even have
to worry about it?
At any rate, when I try to execute "showmount -e" locally, I get
rpc mount export: RPC: Unable to receive; errno = Connection refused
When I execute "showmount -e falconer" from my Solaris box, I get
showmount: falconer: RPC: Miscellaneous tli error - An event requires
attentionError 0
This sucks big time. Whatever happened to just editing /etc/exports
and having it work? I'm a busy person; I don't have time to learn
this stuff all over again every time RedHat puts out a new release.
Frankly, I'm more than a little pissed of at RedHat right now. Every
release seems to be a little more unstable than the one before it.

This seems like a rerun of a very similar thread in this same group a
couple of weeks ago.
>From reading Linux Ethernet drivers, and from reading the specs for a
few NICs, it seems to me that *most* adapters allow the MAC to be
freely set by software (there are good reasons, related to multicast,
why this is so). Thankfully, most drivers just use the MAC stored in
a PROM on the card, which is usually allocated by the manufacturer in
accordance with the rules.
(I picked up a copy of the 1980 DEC/Intel/Xerox Ethernet spec the
other day, which gives the address at Xerox to write to if you want to
allocate your own block of MAC addresses ;-)

On Pentiums and later, you can use this macro to get the processor
cycle count into a 64-bit variable:
#define RDTSC(val) \
__asm__ __volatile__ ("rdtsc" : "=A" (val))
It's not very useful for general profiling, but when you already know
where the hot-spots in your code are, and want to shave cycles off
their running time, it can be very useful.

Perhaps it generates colorful conversations on linux-kernel because
there is no simple yes or no answer?
Recently, 2.2 and 2.3/2.4 have both stopped userspace being able to
use the CLONE_PID flag, since in the several years it has been
present, no-one has seen fit to fully implement it (that is, in a way
that is useful to a pthreads implementation). So while a more
conformant pthreads implementation for Linux is likey to arise at some
point, it seems unlikely that it will use CLONE_PID.

First of all, let me contribute my $0.02 to the flame war. HTML mail
can be useful, provided you're expecting it. I used to receive a daily
newspaper which had an option for either unformatted text, or
html. The html was preferable at the time, because I didn't have a way
to automatically follow hyperlinks on the console, but I could pass
the entire message to lynx easily.
As to the original question, my suggestion is you take a look at
metasend(1), part of the metamail package.

That's not 100% correct. You can use the built-in implementation of NFS,
but for optimal performance/reliability and NFSv3 support, you need to use
the kernel patches at http://nfs.sourceforge.net. Full documentation for
applying these patches is there.

To me, this would indicate that you do not have the portmap service
running. Run ntsysv and ensure it's configured to run at startup.

Nobody is forcing you to use these experimental patches, hence the reason
why they're called 'experimental'.

Subject: kernel compile issues
Date: Sun, 23 Jul 2000 22:46:00 GMT
Hello,
I have Red Hat 6.2 and kernel version 2.2.14-5.0.
The kernel that is set from the initial install loads fine for me.
However when I try to recompile the kernel I get major problems with
things failing to startup or the kernel just freezes up all together.
So, for example if I'm trying to compile support for my zip drive, then
things like my eth0 fails to load, and my sound module fails to load.
And I didn't touch these options when running the xconfig.
I was assuming that when I run make xconfig the options are ones that
are set for my already working kernel. However, is it correct to say
that this isn't the case? That these are arbirtrary values rather?
My problem is I'm not having any luck recompiling the kernel to suit my
computers needs. And I really don't know enough to go through every
option in the xconfig and set it correctly for my system. Is there a
way to determine the settings for the kernel that works for me now and
then when I run xconfig to set all those values the same and then work
from there?
I hope that someone can help me with this.
Thanks
