John,
Here's a little blurb
This is a daemon which handles the task of connecting
periodically to the Red Hat Network servers to check
for updates, notifications and perform system
monitoring tasks according to the service level that this server
is subscribed for
and if you do a rhnsd --help , or look at the init scripts for this daemon
you'll see that it is designed to
make such connections.

Subject: Tar to Tape Above Capacity
Date: Tue, 30 Jan 2001 10:17:12 GMT
Hi,
I've inherited a machine running Suse6.4 Linux which has a DDS4(20/40Gb)
tape drive attached.
There is a cron job already on this machine which writes a tar archive
to tape of every file (tar -cvf /u01 /u02 /u03 /u04).
It then verifies the tar archive (tar -tvf /dev/rmt0).
However the total amount it writes is about 58Gb which is way above the
maximum capacity of the tape. The log files for writing and verifying
the tape contain the same list of files, and if you sum up the number of
bytes of all the files in the verification log you get 58Gb.
How can this be?
Thanks
- Bill.

Dear All :
My platform is RedHat 6.1 .
I am trying to write a perl code that can receive informations from
email and then do something
for me.
In /etc/aliases , I add an entry like :
domyjob: "|/myDir/myCode.pl"
And then , execute "ewaliases".
I've change the shell setting in sendmail.cf from "smrsh" to "/bin/sh"
.
When I try to send a mail to [EMAIL PROTECTED] , I get an error message
back to me that said :

554 "/myDir/myCode.pl"... unknown mailer error 126
Does anyone know where I go wrong here?
I'm sure that file does exist , and I set its property to "everyong
executable".
Please give me some hints to resolve this problem , thanks a lot !!

Arne,
I searched the web after reading your post and found this:
http://kernelnewbies.org/code/mmap/
The concept seems to be what I'm looking for but I've got a doubt:
I believe that when you map a file into user space by using mmap() the
kernel thinks it's a real file and therefore uses cache pages to do that
mapping. What if what you are really mapping is the PCI bus with lots of
changing hardware registers? How can I get rid of any caching at all?
Thanks to all.
David.

That's perfectly correct and organised of them. They must provide the
config and the symbol table for the kernel in order that you can know
what's in it and reproduce it or alter it or debug it. That's good
administrative practice.
> In your opinion, should one adopt this standard practice or not ?
You should worry about other things first! If you are compiling your
own kernel and have no intention of debugging it, the symbol table
(System.map) will do you exactly no good, and you can junk it.
Heck .. I DO debug my own kernels, and I junk the System.map file.
If there's any info there that's not in /proc/ksyms, I don't miss it
or else I make sure it gets put in /proc/ksyms.

There are more parameters to reboot:
warm - skip memory test
cold - perform memory test
bios - reboot by jumping to bios
hard - reboot using hardware.
The default under Linux is:
reboot=cold,hard
To do it most similar to rebooting under DOS you
should write:
reboot=warm,bios
But I think the hard option is supposed to work the
same as the reset button on the computer, but of
course broken hardware might exist somewhere.

Subject: Slow Disk Check for Large Drives
Date: Tue, 30 Jan 2001 12:52:24 GMT
I'm leading up the development of a Linux-based product that requires
alot of storage space. The main problem that we are experiencing comes
when the system loses power unexpectedly and reboots. The following
disk check takes forever if the system has 3 or 4 60 Gb disks. We
really need to speed up this reboot process or we may be forced into
using Windows 2000 (which I loathe). Even with a UPS connected, we
have to take into account the fact that some people will just power the
thing on and off.
thanks in advance,

Write a driver module. If all you want to do is implement
mmap() to allow user programs access to PCI memory space, it's
really pretty simple. The link below points to an example of
such a driver (I wrote it to enable user-mode diagnostic
programs to access a PCI prototype I was debugging).

If you cannot afford the time it takes to do the fsck's (some of these
can be done in parallel to speed it up if you have different drives),
perhaps your system(s) deserve to be run from a UPS that can coast over
the short-term power interruptions, and cause a controlled shut-down for
the longer ones. That way, the fsck's can be bypassed.
