You can also build the exclude file dynamically with the "find"
command:
find /proc/ -print>>exclude.file
find /tmp/ -print>>exclude.file
[etc...]
Launch tar from a script that builds the exclude file, backs up
the system and then deletes the exclude file on completion.

Maybe permission of .rhosts is too liberal. It should be 600. 664
definitely will NOT work. .rhosts should be space separated list of
allowed remote hostname and remote username. Not sure if it relies on
identd (is that enabled on the solaris box?).
Are 'shell' and 'login' lines uncommented in /etc/inetd.conf (not sure how
to enable that with xinetd). What do /var/log/messages and/or
/var/log/secure say when you try to connect?

When you change /etc/lilo.conf to run the new kernel leave the old kernel
specified (perhaps as linux-old). You can reboot to it at any time. If
you are using rpm's to install a new kernel, then use 'rpm -ivh' NOT
'rpm -Uvh'. If you do this then upgrading the kernel is usually safe.

Newsgroupies:
Real obvious question here, but it must get asked.
I have an antique Acer Extensa 366D, tuned for Windows 95. It has a 167MHz
Pentium MMX processor & 32M of RAM.
Needless to say, when I run Mandrake 7.2 & Gnome on it performance is a
little questionable. Sometimes it endures swap fests...
Would it be worth it for me to recompile the kernel, setting every <M> and
[*] option that refers to some exotic thing to < > and [ ], like SCSI support
or SLIP or IPv6 that I'l never use here?
If I did that, the kernel would be smaller, right? Then it would spend less
time even just jumping over the hooks where modules are not even plugged in,
right? And it would occupy less permanent memory, so the user-mode memory
wouldn't need to swap so often, right?
I'd welcome stories from folks who have actually done such things; not just

Subject: How to stop X?
Date: Thu, 28 Dec 2000 04:05:19 GMT
Hello
Could someone tell me how to stop the X server from running. I know that
it's possible to "telinit 3" in Red Hat-based disrtibutions. However,
I'm using a debian-based distro, Storm Linux 2.06, and I can't figure
how to do that. Changing the runlevel won't work because my inittab (see
below) has no "Console Mode". Hitting "Ctrl-Alt-Backspace" is also no
use.
Thanks.

Don't make a move before physically backing up your favorite files, before
getting a second and third opinion, before getting an opinion on a newsgroup
dedicated to your particular distribution, and before reading the document
"The Linux Kernel HOWTO" by Brian Ward.
Follows is a nano-HOWTO that will take you thru the recommended command lines
of a modern kernel rebuild party. Please read silently while I read aloud:
A> install your _current_ kernel source from your distribution's RPM files.
B> Get the new source from ftp.kernel.org, and put it in a directory under
/home. _Don't_ put it in /usr/local; let the system take care of that later
on.
C> tar fxvz linux.9.9.99.tar.gz
D> cd linux
E> cp your/current/kernel/source/.config .
F> make menuconfig
E> a character-mode UI pops up with a menu of options. Check that advanced,
experimental or exotic things are turned off, and that things you expect to
need are <M> or [*]. The former means a loadable module and the latter means
built-in. Prefer the former until you know what you are doing. Save the
settings & exit.
G> make dep clean
H> make all
I> make modules
J> make modules_install
K> insert a blank formatted floppy disk into your A: drive
K> make bzdisk
L> leave the disk in (assuming your BIOS will boot from it first)
M> reboot
Line E attempts to get the same .config file as your current kernel's
distributors used to build it. This implies new features will be Off, and old
features will be all the way you expected them. But be warned; the resulting
kernel might be too big for a single floppy, so you might have to adapt these
techniques beyond where I've ever gone. Or you might have to repeat F and
whack out legacy and bleeding edge stuff that swells kernels up.
Inspect the output of each make to see if it succeeded before moving on.
Makes bubble errors up from their sub-makes, so the last line will say
"Error" if something bad happened below decks.
If the system succeeds, you'l boot up to a login prompt that now says the new
version of the kernel on it. If not, something will screw up, and you'l
e-search for whatever error message you got. But, to get the old OS back,
take the floppy disk out of the drive and reboot. It's that simple.
If you are trying to rebuild the same version of kernel as you already have,
you'l need to e-search how to back up the current module set. Line J installs
the modules into a directory named after the kernel version, but if this is
the same version as you already have you'l write all over your existing
modules and might never regain control if you introduce a bug. I'd just go
out of my way to build another version rather than risk this mayhem (and
there are certainly enough to choose from), but there are HOWTOs out there
detailing how to do it.
Line G compares the current set of options to what .c files include which .h
files in the source, and it upgrades all the Makefiles to reflect these
settings. This means that, for a given configuration, if you edit a .h file
only the exact set of .c files that use it will recompile.
After you get a kernel you like, read the HOWTO to learn how to overwrite
your existing bzImage with it (the actual Real Kernel on your hard drive) or
how to let LILO switch between one and the other.
As I'm trying to do these ominous things myself this week, I'd appreciate any
revisions to my nano-HOWTO...

Well I squinted and looked at the chip and noticed its a ET4000 W32.
The x-windows config program is telling me to install the W32 server in
a specific directory. Being very new to linux I can't find the server
anywhere nor do I know the proper -'s to untar and uzip. Also I only
have download access from a PC, so I figure I can put it on an ISO CD.
Any info will be appreciated.

Yes compiling a kernel to include only what is needed by the system will
increase performance to some extent but may not fix a "swap fest"
problem. There are other things that can cause it to go into "swap
fests" to the point of slowing the system to a crawl. A couple of things
that can cause this is "bdflush", "buffermem" and "kswap".
You can check to see where these are set with:
cat /proc/sys/vm/bdflush
cat /proc/sys/vm/kswap
cat /proc/sys/vm/buffermem
If you can post the output from these and see if this could be the
cause.
Or in /usr/src/linux/Documentation there is info on these that may help.

Get more memory . Your kernel will only make a marginal difference. Get

It would save you a few bytes, but it wouldn't solve your problem. If you
run a Gnome desktop in 32M it _will_ swap. Gnome is a hog.

What do you mean by "no use"? What happens? What are you trying to do?
At a guess, you have xdm/kdm/gdm running. If all you want is a text
console, just type 'control-alt-F1' to get to one and 'control-alt-F7' to
go back to X. You have six text consoles, accessed via 'control-alt-Fx'.
To stop X go to a text console, log in as root, and type 'killall xdm' or
'killall kdm' or 'killall gdm'. To start it again log in as yourself and
type 'startx &'.

This has nothing to do with inittab. Changing the runlevel doesn't stop X
because xdm/kdm/gdm is set up to start in all multi-user levels (this is
wrong IMHO). Go into /etc/rc3.d and change the SXXxdm/SXXkdm/SXXgdm to
KXXxdm/KXXkdm/KXXgdm.
