Greets John,
I'm a bit confused about your situation. Your subject line indicates you
are using
RedHat 7.1 but your message says you upgraded from kernel version 2.2.19
7.1 comes with kernel 2.4.2
Did you downgrade your kernel at some point?
Why does anyone need to have their hard drive go to sleep anyway?
If you are concerned about wasting energy, turn the system off.
If its a server you wouldnt want the drive to go on standby anyway.
You obviously dont want the system running 24x7 or you wouldnt be shutting
it down.
So leave out the standby settings and just turn the system off if you arent
using it.
Another option is to let the machine "wake up" before you shut it down.
The man page for hdparm says:
> Under such circumstances, the drive may take as long as 30 seconds to respond

I'd guess you are having a problem because the system is trying to unmount
the filesystems
before the drive is accessable and causes the hang.

Subject: disk space disappearing
Date: Sun, 29 Apr 2001 16:47:24 GMT
hi,
i've got a redhat 6.2 system. the space on my /home filesystem is being
reduced by around 20 MB per day and i can't seem to find out what's doing
it.
i've tried the following commands:
find . -mtime -1 -print -fls files.txt
find /home -mmin 60 -print -ls
but i don't see anything that's growing or even really significant in size.
i figured that it might be some logs, but nothing shows up as having grown
enough in the 24 hours before running the above command to account for the
loss in space.
can anyone give me any pointers regarding variations of the above commands
that might find something i'm overlooking? or any other clues?
so far about 200 megs have disappeared!
thanks in advance!

Zip/Unzip are available on the RedHat CD. They didn't get installed by
default on my RH6.0 box, but they are there.
I've just had a quick look on the RH site, both Zip and Unzip are
available to download.

Hm, sounds rather strange, are there other users on your box,
who might eat up the space?
Using this command on two days and then running "diff filename1
filename2"
should show something, otherwise, you may have been hacked?
ls -al /home/* > home.`date -I`

It means what it says. The driver doesn't find what it's looking
for where it is looking for it. You can do the obvious things that
derive from that observation ...

Yes, but it is hardly a good reason, is it! Go and look up your modem
in linmodems.org. It strikes me that this is possibly not a winmodem,
but the lucent venus chipset, and therefore doesn't need a driver.
Check it out in /proc/pci and via /sbin/lspci.

Wait! Your subject says "PCMCIA". Please don't hide such facts away only

You can't use the ltmodem driver, which is for pci (or isa?) devices,
as far as I know. You need to load the pcmcia drivers and set up pcmcia
and select the generic serial driver. If that doesn't work, then you
HAVE a winmodem on a pcmcia card! Amazing.

Aha! So you KNOW you have to run pcmcia. You really do believe in
slipping things in sideways ...
> product info: "V90&K56Flex PCMCIA FAX MODEM", "", "", ""
Well, that doesn't tell us much. What does the generic pcmcia modem
driver make of it? You need to add the ident to the pcmcia card
database in /etc/pcmcia/ if it isn't there already, if the serial
driver isn't loaded by default when the cardmgr sees it.

Subject: X sessions randomly closing
Date: Sun, 29 Apr 2001 10:52:02 -0700
I've recently upgraded from RedHat Zoot to Guiness with the 2.2.19-7.0.1
kernel and am having a problem that's driving me up the wall...
it seems that at random times the server decides to disconnect my X sessions
(I'm running eXceed on NT using the telnet protocol)... it's not a timeout
thing since sometimes I'm busy typing and my X session just terminates.
I have another Guiness box running the 2.2.18 kernel and if I open a session
to that box (from NT) I don't have the problem... if I telnet from the .18
box to the .19 I'm also ok, but if I open my session to the .19 box directly
from NT, I keep getting disconnected...
is anyone else having these kinds of problems? I've spent a lot of time on
DejaNews but haven't come up with anything useful.
1k thx - e
p.s. btw, the message I get is "Connection reset by peer".

This initiative is not enough. It's trash.
It's HP's idiotic atempt to keep the linux comunity quiet.
The HP's way is like to lead sheeps to slaughter.
This is my reason for this opinion:
The HP's support range *does* not know about this project and it's
results. The drivers are *not* officially delivered by HP.
Many printers are not supported like my HP1220C/ps, by the way HP lies about
the PS capabilities of this Printer. In the web the tell "PostScript Lev. 3",
but it is defnitly PLC Lev. 3. Idiotic.
Asking the HP Support Hotline for Drivers causes a big laugh.
Better not use Linux and HP Products, if you want avoid troubles;
it may work -- mostly not or only after big manual actions.
(Search Web, Usenet, download, compiling, installing, testing, failing,
startup again by recerche ...)
I have collected expierences with tons of different HP Deskjet Printers,
Scanners, Botebooks, DATs (HP 15xx, Surestore breaks up as fast you
start useing it, but the drivers work, the physically quality is trash-like,
after disapointing 75 hours opf usage the last 1537A one crashed, now
Sony SDT11000 works includided 3-times waranty) and much mor disapointing
expieriences with HP Products

"ulimit -u" is what you need.
"man ulimit" in case you have further questions.

You can limit the number of processes a user can have in
/etc/security/limits.conf but I'm not sure if you can limit only the
background processes.
You would also need to enter the line below to /etc/pam.d/login to tell
the system to use the limits.conf file. You can enter it near the end of
the file after the "pam_pwdb.so" line.
session required /lib/securitypam_limits.so

Another way of doing this is with:
chkconfig httpd reset
service httpd start
The first line sets the service to start up in the runlevels specified in
the /etc/rc.d/init.d/httpd script (/etc/init.d/httpd on some systems), and
for it to start up in the right place in the sequence.
It's a lot quicker than using a GUI tool, IMO.
