So you know that the server doesn read your exports file. Restart it

There is no reason to expect that allocated memory will
necessarily be (or not be, either one) swapped in and out again,
even once.
It depends entirely on available RAM and system usage. If there
is enough RAM, it will never be swapped out.

What is "contiguous RAM"??? If that means one continious linear
address space (and no other meaning makes sense to a user
program), then most certainly it will always remain at the same
range of addresses, before and after swapping.

Not even sure how to start snmpd after installing ucd-snmp.
Do you know of any good documentation on Linux - SNMP - MRTG?
In addition, I need to monitor the various services like http, ftp, pop,

How do i configure SNMP to be able to this?
And how do i configure MRTG to retrieve this info from SNMP?

How are you defining "CONTIGUOUS chunk of memory" ??? If you
mean a linear address space, then you will in fact get it. If
you mean contiguous in physical RAM, you can't get it and it
has no significance anyway because of the address translations
inherent in the system's memory management.

Hello,
why do you want to do this, since only root can write to /var/log,
if someone has root access he may change your changes back with chattr as
he likes?
Anyway you could chattr the .gz logs from cron with a small script like
this:
#!/bin/sh
for i in 'ls /var/log/*.gz';
do
<your_chattr_command $i>;
done
I would be carefull with the real logs, syslogd, writes to the inode...
Good luck

Hello Harry,
after compilation of a kernel from the sources the missing file
'version.h' will be in the proper place.
Same thing with compilation of 'lilo' and missing 'autoconf.h'.

Some 10/100mbit NIC's have both connections for
coax and UTP cables. They only do 10 mbit when
connected via coax. For 100 mbit you need
a (crosswired) cat-5 UTP cable.

Since the RH 6.2 install did not put a GUI in when I selected 'server'

So:
Is there a simple step-by-step instruction somewhere on how to get KDE

Read the init commands of the MODEM, they usually look like atdt(phone
number), which means (at) - command, (dt) - dial in tone dialing, (phone
number) - phone number.
What you need is: atdp(phone number). (dp) - dial using pulse dialing.

Eh, some time ago, I had the same problem after a crash. It turned out to
be /dev/null, that was replaced by a normal (empty) file.
Try to do "ls -l /dev/null" - it should give something like
crw-rw-rw- 1 root root 1, 3 fre jan 05 15:33:21 2001
/dev/null

Mine wants myusername.ppp . I suspect that if in my chatscript that I
use to login,
I put something like this at the end:
'assword:' '@#$%^&*+'
'TIMEOUT' '5'
'~--' ''
'' 'ppp' <---<<< Not there now.
it would work too, but I never bothered to try it. I am pretty sure my
Windows stuff does not know to put the .ppp in at the end of the login.

Helps tremendously Martin, thank you.
After a kernel build I'd been making "mrproper" thinking this would be
a nice state to leave the source tree in, but looking at the Makefile
I see that this deletes "version.h".
I conclude from this then that:
a) "make clean" is the happiest state to leave the kernel source tree
in after a kernel build
and
b) it's necessary for the source tree to be present in this state
before a lot of programs can be compiled, or is it only necessary for
/usr/src/linux/include/linux to be present - which is linked back to
/usr/include/linux? (my head's spinning)
Forgive me, I'm quite new to all this.
Thanks again

You're not worth the effort.

But snipped the bit you didn't want to see because it'd make your stupid sig

The "accepted" sig length is 4 lines although some people go 2 or 3 lines
