Sure! And Linux is Linus' (et all) version of freebsd.
The point is: they all work together and they're all open. Microsoft
is pretty much the only closed/secret shop left.

Better than that, the FQDN _ought_ to be replaced by the MAC address
of one's Ethernet card; that is supposed to be "nominally globally
unique" in and of itself.
There's a program "uuidgen" that allows taking _either_ approach,
whilst using the formal DCE format.

Hi,
When I used Gnome, the xscreensaver daemon was invoked
automatically. I just recently changed to WM, and would like to have it
starts auto as with Gnome. I try to append the command
exec xscreensaver & in .XClients-defaults but that doesn't start the
problem. What do I have to do for it to auto in WM.
Thanks for all inputs.

Hmm, well that is strange. You might like to check to see whether or not
there is a later version of your dhcp client program. It seems strange that
you get the data some of the time and not at other times.

First, the CPU has to execute the code and read the data out of the
physical RAM, so if Linux could try hard to swap a "low-priority"
process out to disk I think it would result in excessive, maybe
constant disk usage.
Anyway, I think your concept of what is happening is backwards. When
you start X after starting other programs, the other programs are
moved out to swap if room is needed for X. The other programs may be
loaded at lower virtual addresses, but the higher virtual addresses
where X is loaded afterwards will be the ones in RAM.
The swapping is occurring because either the first-loaded programs are
actually being executed by the CPU (and again, have to be pulled into
RAM - which means the Xwindows stuff has to be swapped out, and in
again when X is used) or because X needs to swap some of itself or
executing X applications to have enough room.

Instructions can be found in the kernel documentation, in the
svga.txt file in the linux source tree, usually located at
usr/src/linux/Documentation/svga.txt:
[snippet begins]
The video mode to be used is selected by a kernel parameter which can be
specified in the kernel Makefile (the SVGA_MODE=... line) or by the "vga=..."
option of LILO (or some other boot loader you use) or by the "vidmode" utility
(present in standard Linux utility packages). You can use the following values
of this parameter:

Strange enough... I build a Linux from Scratch this weekend as well. Got the

except for ed. I've tried installing it now, once the machine is fully

Maybe, if you have the exact make error messages, you should post them to a
forum on www.linuxfromscratch.org, or open a bug report for it, or
something.
Please let me know what you do, since I need to get this resolved as well.

used: sum of all memory usage (pretty unimportant IMO)
free: free memory (unimportant as well)
shrd: shared memory (libraries I guess)
buff: buffers (especially big if you are doing a lot of stuff on your disk)
cached: memory used for disk caching
The number that really interests you is used-buff-cached because
this is the amount of memory really used up by programs directly. You can
get this number by running "free", it will give you a line that says
-/+buffers/cache which contains that information.

Looks like you are really using a lot of memory (121M out of 126M used). If
that's normal for your machine you should consider getting more RAM. 128M
is not that expensive.

Windows does *not* see the linux partition, and it never will.
Windows will see extended partitions (type 0x05/0x0F).
And it expects a windows partition inside. If that's not there, it'll
assign a drive letter to the extended partition. That's probably what you
have seen. It can be solved in the partitiontable. If an extended partition
contains only linux logicals, make the extended partition type 0x85. That
way, windows will never be able to see that drive again.

126596K (available) - 964K (buffers) - 81380K (cached) = 44252K
Meaning, you're effectively using only 44MB of memory, the other 81MB is
buffers and cache. If you see this happening, with buffers and cached so low
that you can work out (using above function) that you're actually using more
than 64MB, then only should you consider upgrading (in my opinion). Having
81MB for cache & buffers is more than sufficient.

There is no reason to do them in the order released, or one at a time.
Let RPM work out the dependencies!
If it complains about missing packages, do a rpm -Uhv on them, then try
the rpm -Fhv line again.
You could even use rpm's various dependency options to tell you which
packages must be rpm -U'd first. Once you put all this in a script, you
have an up2date equivelant.
