This should be something that goes beyond what NIS does. Something that
contains info for every system related resource and also has a standard
interface which can be abstracted, get<foo>by<bar> is only good if you're

NeXT stores application info under the home directory. It turns out it's quite
nice. I think a system that stores this kind of stuff in the home directory is
the way to go, if someone needs an exception allow for that in the framework
that is designed, i.e. have multiple datasets, some that are general others,
more specific, and have the lookup mechanism choose the one that best fits the
host or system.

I have noted a problem with nfs getting lousy peformance. The issue was,
in my case, duplicate nfs packets being transmitted by linux (tcpdump is
handy). Strangely enough, this issue just 'went away`, I got my peformance
back and have not noted any further instances of duplicate packets. There
is another guy on the newsgroups with the same problem I believe - can you
'snoop' from the solaris box or tcpdump from linux and see if thjis is
your issue too?

Such a person is not going to install an operating system, she is not
going to install a serious program. Furthermore, most of the problems
installing Linux come from trying to install it on a system with another
os already installed. As one of the posters on this thread said, Linux
can be obtained preinstalled and setup to boot directly into X.
Why, oh why, does everyone want to turn our neat Unix clone into an
inferior mass market proprietory peace of juck? Run Linux if you
want your very own personal multi-user unix system. If that's not what
you want a company in the northwest has several os you can take your
choice from.
Everyone wants to change the world. Luckily for me Linus just wanted
an affordable unix system. Thank you Linus, et al.

For that matter why limit it to just Linux or Unix? Some applications span
multiple operating systems. For example lets say I am using Netscape on
a number of different platforms, wouldn't it be nice if I could just set
some configurable parameters and have the apps look for configuration/app
information on other machines?
Lets say I want to have netscape use my config from my linux system at home
while
running Communicator at work on a PC. I think some kind of path specifier
could do this, again with the right library, and a server on my home
machine that has been told to "publish" parts of my config info. Security
could be an issue for some situations but that is also solvable with a
secure protocol.

Subject: Where is the bound port in TCP found?
From: Ayman El-Khashab <[EMAIL PROTECTED]>
Date: 30 Dec 1998 18:36:28 -0600
I currently have a piece of code that I am writing for a custom
application. If my understanding of tcp is correct, the client makes
a connection request to the listening port on the server (say 23 for
telnet). Then the server responds with a port to which the new
connection is bound (mabye 1045 or something). How from a tcp packet
can I find this information? I am looking at the data as it is passed
into the tcp stack (tcp_rcv i think).
I believe what I am looking for is in the sk_buff, but I am uncertain.
At the moment, I look at the skb->h.th.source. So for telnet I see
23. Either I am missing something here or alternatively, how does the
tcp stack know which connection this is?
ultimately, i would like to get something like:
server_ip and server_port -> client_ip and client_port.
The client side and the server_ip i have, but I cannot figure out the
server port.
I'll be grateful for any help i get . . .
thanks,
- ayman

Ouch! Hmm, if the OS could tell processes that it's almost out of
swap space, then I bet some of them could free some up. I guess
what's really needed is some whay to notify the user/sys admin
so they can step in and make the proper decisions.

It kind of assumes someone is around to deal with the problem. I
suppose a monitor program could watch for the processes that are
causing the problem and request they address it by sending them
a message/signal ... Failing that the program could be halted
automatically and notifcation sent to the user/sys admin. On
last resort the program could be shutdown. I am loath to
shutdown programs automatically, but if they are the offending
process and don't listen to reasonable requests then it's justifiable.

There are MANY reasons to want to run applications for M$, like it or not.
For example, the finance software for Linux is still very limited. I have to
maintain a DOS partition
to run that software. The original question is a good one. It would indeed
be nice to be able run many
Win applications as well as the excellent Linux applications. but not all
Linux applications are excellent.
Some are shocking.

When I said "source directory" I meant "build directory",
/usr/src/redhat/BUILD/linux. That's where you run "make config".
Then copy the resulting .config file back to
/usr/src/redhat/SOURCES/kernel-2.0.36-i386.config.

This means that the original redhat packages are already installed, as
they must be for you to have a working system. After you build your
new packages you will use RPM's upgrade switch to simultaneously
uninstall those and install your new ones.

nls_iso8859-1 _does_ have to be compiled in in the ordinary way - you
