Two things:
1) Writing to the network, under proper conditions, can be faster than
writing to disk. If your NFS server has a *lot* of fast RAM, and is
used primarily as a "network swap device" over a very fast [eg gigE]
private network, you'll find you beat swapping to disk all to hell.
2) Drives may be cheap but rack space is not. Network swap is the only
viable alternative [other than dispensing with swap altogether] if you
want a truly diskless workstation, either netbooting or booting from
cd-rom. The internal drives on most of the production servers I've
dealt with are used for nothing but swap and logging. Set both things
up to run over the network, pull out the hard disks and cram everything
into a smaller case, and you can cut your rack space in half or even by
two-thirds.
Up until about two years ago, I'd have agreed that network swap was an
academic problem. After having dealt with systems that could benefit
greatly from it, I don't think that anymore. I still can't find the
original reference I mentioned about a research team working on network
swap... Carnegie Mellon springs to mind. Does anyone else have any
references to such things?

You are taking this too personal :-)
There are reports of americans who 'misbehaved'. And that's a FACT. There are records
of it.
The soldiers in question were punished by the US Army. Again, here are records of it.
But it's
not me to make judgements. There were some bastards but most of them managed to do
allright
given the circumstances.
I'm saying this again : It's not up to me to make judgements ! It was war, everything
was
different. But we were liberated and that was the main thing.

If you download version 0.16 and can't compile on any of rh5.0 5.1
5.2 and there exists a patch for more than a year that fixes that
compile problem then 0.16 withOUT patch level 5 is obsolete and has
been for more than a year.
That is why i would hope that someone could tell where the 0.16 was
downloaded from and replace that version with 0.16 patch level 5
so unknowing people can download the diald program and compile it
successfully. This has been a frequent point on the diald mailing
list last year.

0.16 patch level 5 I wouldn't consider obsolete.
If 0.16p5 was downloaded in the first place there wouldn't have been any
problem.
BTW, there might be some problems on RH6.0 with the new style ptys.
but that is anouther story.

Subject: Strange glibc2.1/NIS behaviour
Date: 02 Jul 1999 09:15:32 +0100
I have a cluster of machines, some of which users are allowed to login
to, and some of which they are not. I defined a netgroup `login' which
contained the allowed possibilities:
login (restricted-box,chris,) (unrestricted-box,,)
(I've checked using innetgr() that this netgroups file is being exported
correctly by NIS.)
I then added two lines to /etc/passwd on each machine:
+@login::::::
+:*:::::/bin/false
which ought to enforce this policy. Unfortunately, things are behaving
strangely...
restricted$ getent passwd
root:x:0:0:root:/root:/bin/bash
daemon:x:1:1:daemon:/usr/sbin:/bin/sh
[...]
chris:x:1000:1000:Chris Webb,,,:/home/chris:/bin/bash
thingy:*:2000:2000:Wibble,,,:/home/thingy:/bin/false
ie the correct data is given when I list the whole file, *BUT*:
restricted$ getent passwd thingy
thingy:x:2000:2000:Wibble,,,:/home/thingy:/bin/bash
ie the library is working here as though there was +:::::: in
/etc/passwd. This also carries through to /bin/login; every user can
login to all the machines.
Has anyone else seen problems like this with glibc 2.1 and NIS under
Linux? (FWIW I'm using nis 3.3.2-1 and libc6 2.1.1-12 under Debian
potato.)
Cheers,
Chris.

Our system is consisted of a server and 7 clients, all running RH5.2 and
kerneld 2.2.2
We upgraded one of the machine to kerneld 2.2.10 and found the following
errors while booting:
Mounting remote filesystems.ypbind[228]:clnt_create for server
192.168.1.1 fail
192.168.1.1 is the server. While there's still the login prompt but the
remote file system is not mounted !!! and we can't ping to the other
machines !!
Any ideas ?? Thanks in advance.
ps. we'd checked the /etc/fstab , /etc/exports in the server,
/etc/hosts, /etc/hosts.equiv, everything is just intact and the same as
the other clients running kernel 2.2.2. We'd NIS also and 192.168.1.1 is
the server.

No, I haven't. Although I have a number of implementations of Java (from
Netscape, Microsoft, Apple, Metrowerks, Sun and blackdown -- if I haven't
missed any), I don't yet have any direct-to-machinecode implementations.
Has anyone? 99.99% of the Java out there is interpreted or on-the-fly
compiled and is much slower than C/C++/Pascal/Dylan/FORTRAN, so that's
what I'm comparing against.

Hi !
You might make many things :
_ go to "/etc/rc.d/rc3.d/" and move "S45pcmcia" to "S08pcmcia" : force
PCMCIA network card to load BEFORE network services.
_ type "setup" and disable "named" (DNS) service, then check that your
hostname (command "hostname") corresponds to what you find in
"/etc/hosts", like "127.0.0.1 -> localhost, laptop -> 192.168.15.2, by
example.
_ Reserve interrupts like "03, 05" for system use, leaving others (09,
10, 11) for PCMCIA device by editing "/etc/pcmcia/config.opts" or
"/etc/pcmcia/sysconfig/pcmcia", I don't remember which.
This should much help, Linux usually works perfectly on laptops.

Hi !
Beware, standard POP-3 support is dealt by IMAP package, so you MUST install
IMAP package absolutely before trying anything. In fact, POP-3 is not

Have you benchmarked Java vs C on the same machine? (No, I don't
mean benchmarking C on a machine vs Java running on a p-machine
on that machine); there's certainly nothing in the design of
Java that would make it much slower than C on the same machine.

Jonathan is right - this isn't debugging. Put a line "debug" or "-d" in your
/etc/ppp/options file. Restart the ppp daemon and connect to your ISP. Between
the Connect and the Modem Hangup there will be a lot of messages concerning the
LCP (Link Control Protocol) negotiation. These messages will give you the answer
which parameter fails.

Because sometimes you need a Virtual Private Network (VPN). VPN's
are essentially a private network (Ie, a 10.0.0.0 net) encapsulated
within an insecure network like the internet. So if the TD bank had it's
hq in Toronto, and a branch in Saskatoon (Where I am...) and couldn't get
a fast enough connection between them directly, they would use PPP
tunneling over the internet. So now the bank has a wide area network
between saskatoon and toronto, over the internet.

Please have a look at StarOffice (which is available for free for=20

This Office software looks very similar to MS Office but lets you use=20=

StarOffice is available for these platforms and it includes=20

very simple for your users: given the fact that StarOffice has got=20
that UI resembling everybody to the MS Office and given the other fact=20=
that there are powerful data exchange capabilities to and from MS=20
Word, Execl, Powerpoint... i could imagine the following solution:
- Let them use their beloved Windows but install StarOffice there.
- First they will work with their MS Office products and start
their Word or whatever from the integrated StarDesktop while
StarSchedule takes care for and will let them organize their
time-data.
- After a while some of them might start playing around and
discover that *StarWriter* does the same job while offering
a quite more sophisticated style management and faster ways
of document navigation...
Then you can let them use StarOffice for most of their work,
if they want to do so. Your advantage is that due to the
very similar user interface *nearly no training* is needed
for somebody converting from MS Word to StarWriter. :-)
- After a while of making good experiences with StarOffice
you could take them apart and ask if they would try do use
_Linux with KDE and StarOffice_ instead of using that old=20
_Windows with Bluescreens_.
- If that works fine they could use Linux and exchange their
data with that poor colleagues who still use Windows and
Word or Windows and StarWriter.
- At the very end even the extreme Windows Fans will come to
you and beg for being allowed to forget about it and also
use Linux now and become as happy as their colleagues.
- - - - now the *critical* part of my message begins - - - -
- Soon after converting everything to Linux the more interested
of your clients (the Power Users) will come and ask for some
training or some books about the bash or similar things.
- You know what comes next: one or two of them will end up
starting to do the job with (K)LxY, and soon after that they
might even take xemacs and pure LaTeX and forget about all
that Office Software... :-(
Ok, that was enough about it for now, perhaps i should stop working as=20=

Well, if you followed the steps in that document, you have a whole list
of debugging output in /var/log/ppp. At this point it would be more
profitable for you to post that. On the other hand, I suspect that you
did not actually follow the steps, but were looking for KzPPP comments.
In that case noone can help you. It is impossible to help with the
minimal information you have provided. You have not given any debugging
output. You can do all the reading you want, and you will also not be
able to fix it without at least looking at the debugging output.
Now the problem may lie with KzPPP (what is that or is it KPPP ) or it
may lie with your setup, or it may lie with your ISP.

Nope. You are wrong here. The right question being: what set of types it
might be applied to? And that problem is *not* TC. Especially with the poor
polymorphism provided by templates. In that case:
TYPES( main ) = \{map(int,void)\}
TYPES( call_me ) \subset map(pair(_,int),void)
map(pair(int,int),void) \in TYPES( call_me )
map(pair(x,int),void) \in TYPES(call_me) =>
map(pair(x,int),void) \in TYPES(call_me)
Minimal solution:
TYPES(main) = \{map(int,void)\},
TYPES(call_me) = \{map(pair(int,int),void)\}
In this case functions are not polymorphic at all. Even if they were you
wouldn't have to compile an infinite amount of variants.
Notice that you don't need to know the full set of potential types -
natural polymorphism of operations restricts the depth. Now, one *can*
make a TC type system. But not with the piss-poor set provided by
C++ templates. They are insufficiently expressive for real work, let
alone for being TC.

Your /etc/resolv.conf should contains:
domain jaring.my
nameserver 192.228.128.20
nameserver 192.228.128.18
ps: Please change the nameservers to your favourate DNS servers.

If you're looking for a newserver for a small network, I would suggest
Leafnode instead of INN. It's dynamic, it's almost doesn't need any
configuring, and it's fast. Check it out at:
http://wpxx02.toxi.uni-wuerzburg.de/~krasel/leafnode.html
There are also some links for configuring INN at that site.
