A silly question: Do you have a /etc/pap-secrets file configured and
the pppd option "name <username>" ? PAP authentication requires both.

Subject: NFS and process accounting
Date: 29 Jun 1999 01:13:33 GMT
Hi,
I'm trying to get process accounting running on a system running NFS/NIS.
Without NFS/NIS enabled, accounting works fine (as it should) but with NFS/NIS enabled,
accounting does not work. It might have something to do with the inability to monitor
the
exported partition. Anyway, I'm getting a LOT of junk when NFS/NIS and process
accounting are
both enabled.
I was wondering if there was anyway to do accounting at all with NFS?
Thanks

Vikram,
IIWM, I'd put the firewall on the 75MHz, and the file server on the
Celeron.
Thin-net is 10Mbit; fast enough for 16 or so stations.
How to do your "user" thing:
1) Make only one '/home' partition in the whole net. (machine 1) And
export it.
2) DO NOT create a /home partition on the other machines. If you
can't install without it, make it real small (less than 50m).
3) When machine 2 boots, have it 'mount machine1:/home /home' This
way, everybody sees '/home' on '/home', but there is only one copy of
the data. (Mounting on top of an existing directory will mask the data
in the "real" directory; you can use this trick to make 'net is down
local user copies'.)
4) Put local copies of the (shared) applications in /usr (All
machines have a /usr, and a /root, etc). Having local copies of
executables (and /tmp, /scratch) will cut way down on network traffic.
Note that root's home directory is /root; it's good to have root local
to every machine.
Make sure every system is mentioned in /etc/hosts, and you'll probably
want to set up ".rhosts" on machine 1.
Oh, and do yourself a BIG favor. Do a net search for the "linux
documentation project". Once you find a local mirror, bookmark it.
Gary.

Greetings Andrey,
I will try anything if you want to give something a shot....
Here is the info I get when I plug the Cisco into the hub and run a winipcfg
in Win98
Host name Rich
DNS servers 207.108.32.1 and 204.147.80.5
Node type =broadcast
IP address 10.0.0.2
Subnet Mask 255.255.255.0
Default gateway 10.0.0.1
DHCP server 10.0.0.1
In case I havent told you, I have a dynamic IP and the router is running in
PPP and NAT.
If I understand correctly, I dont have any choice with USWest when it comes
to bridge or PPP. I could be wrong but I think they may dictate that.
Regards,
Rich
PS: Thank you very much for your help....

You are not willing to authenticate using Microsoft's version of chap.
But tell the peer you would like PAP.

The peer does tell you that PAP is ok too and you agree to use it.

You are sending your login and password but the peer does tell you that
there is something wrong with it. If it would not be a NT-server I would
have remarked that the error-code 691 should be documented with the
server.
Try following:
- check your login and password
- recompile ipppd with Microsoft-CHAP support enabled and setup
/etc/ppp/protocols.chap. Remove options like "-chap" from your
configuration.
> Why doesn't the authentification over PAP work ??
Does look a bit like the server is configured to accept PAP but does not
find the password database or similiar.

...Which basically goes to say that the C++ implementation is not as
*mature* as the C implementation.
They may both share the same peephole optimizer; they may both share the
same RTL code generators.
But they manifestly *do not* share the same parse tree generator.
(That's kind of the point of them being separate compiler front ends.)
It is quite evident that the front ends generate code differently, and
this nicely explains the differences in behaviour.
It is manifestly true that G++ FE != GCC FE, and it is pretty evident
that the GCC FE is *vastly* more mature. Which strikes me as obvious; I
was using GCC (ANSI C) ten years ago, and considered it quite stable,
when G++ was not even worth considering.
All of this being said, it is possible for the code generator for C++
(particularly for EGCS) to persistently underperform the C code
generator, due to the following two factors:
a) They are separate.
b) C++ is a more complex language, thereby making it more difficult to
write a generator producing code that is both correct and efficient.
Don't misread that as a claim that the complexity makes it inherently
*impossible* to make a C++ implementation more efficient; it merely
indicates that it is a difficult task.

I've been using it about two weeks now and all is well. It works under
both Win98 and Linux RH 6.0. I'm using a 2.2.9 kernel, but the stock RH
2.2.5-15 should work fine too. Linux drivers can be found at:
http://www.absoval.com/linux-wlan/
Cost is 230-240 US$ per NIC (from the US mail-order web sites)
Zoom may be releasing an 11 MB/s card soon. Call them before you purshase

For calling something regulary cron is the rigth thing. It should have

information. Read the pages noted in the "SEE ALSO" part too.
For posting to a NNTP-server needing authentication rpost should be the

The Linux Kernel does not implement the TLI/XLI interface but the
BSD-style socket interface. There is a development moving on to
implement TLI/XLI. It's called Linux-Streams, or short LiS. Check

There is not (that I know of). However, I have the framework pretty

Just as I thought. Rather than presenting a real program, and
examining the instructions generated and the real execution
speed, he gives us a toy program and compares a line count
of the runtime apparatus.
If the claim had any merit we would have seen real evidence instead
of hastily-contrived FUD.

Hi,
I'm trying to install Red Hat 6.0 on an IBM PC 365 and I was having
trouble autodetecting the network card earlier (an IBM token ring). I
did some investigating and found the exact type of card (which is
supported by linux), io address, and irq settings and supplied them as
options. The card then detected and I got to the TCP/IP config screen.
After about 3 seconds everything locked up and I could no longer type
anything. Does anyone have any ideas what might be wrong or how I might
fix this? Any help would be greatly appreciated.

Of course I'd rather write inheritance in C++, but the architecture
of GNOME and much of the Linux kernel are predominantly emulations of
virtual functions in C. While a clear notational win, the lack doesn't
seem to slow anybody down. Still, most times I see a function pointer
it turns out to be virtual function dying to be recoded recognizably
in C++.
Alex Stepanov has said that he would happily do without member functions,
and regrets those parts of the STL spec that require them. I suspect
Alex doesn't use function pointers much.
