On 15 Feb 1999 00:17:01 -0600, Leslie Mikesell did say with great verbosity:
:In article <[EMAIL PROTECTED]>,
:The only problem is that you end up with 2 copies, one of which is
:outdated.
Ahh, yes. We need an Obsolete line for sendmail-cf. Thanks for pointing
that one out.
:Yes, thanks. There are about a billion ways to set up sendmail. What
:I'd really like to see is the reasoning behind the choices where you
:are different from the stock version and perhaps pointers to the
:details on how to use the features.
sendmail.cf in our package only differs as much as the 8.8.7(?) rpm .cf that
comes with RH 5.2 stock... umm, to say the least, that's a lot.
Main differences are the access database, RunAsUser, PrivacyFlags,
localprocmail, and relay_based_on_MX (which actually works in 8.9.3 :)
:For example, your anti-relay
:configuration is completely different and caused me a bit of trouble
:because I forgot that my DNS wasn't set up to reverse-resolve some
:DHCP-assigned addresses that can originate mail. That isn't your
:config's fault, but a mention of how yours was different might have
:jogged my memory about how my other setup allowed relaying from
:the address range.
That's in the access database (/etc/mail/access) and because of 8.9.3's
hardline stance on relaying is likely a default too. Add your 24/16/18 bit
address (without the trailing 0) to get it to accept mail from the entire
class C/B/A.
:And I still haven't found what the confPRIVACY_FLAGS settings mean.
Page 51 of the ops manual explains all of the PrivacyFlags
(/usr/doc/sendmail-rhcn-8.9.3/doc/op/op.ps

IIRC, filesystem compression is in the works but not yet implemented.
If you check under filesystem attributes, you'll find flags for things
like compression. These are intended to be implemented at the file, not
filesystem level (e.g.: each file is individually compressed).
You're probably better off assessing what is using the bulk of your
space, and either compressing or deleting selected large files or
directories.
A handy way of finding current major disk utilization is to use the 'du'
command, as root (to ensure you can read all files):
# du -sx * | sort -nr | less
....which summarizes the files and directories in the current directory,
for the current filesystem, then sorts them largest to smallest.
Recurse down through large directories.

Does your modem work for any other programs? If not, then you may have an
IRQ conflict. REALLLLLY slow i/o is one syptom of having two devices
sharing the same IRQ. If you modem is COM3, for examaple, by default it
will be using IRQ4 which is also used by COM1, or if it is COM4 it will be
on IRQ3 which is also used by COM2. If this is the problem, you need
to: 1)rejumper the modem to move it to an otherwise unused IRQ, 2) use
setserial to tell Linux which IRQ it is using.
I've got a modem on COM4/IRQ5, and my /etc/rc.d/rc.local script includes:
setserial /dev/cua3 irq 5 spd_vhi
/sbin/irqtune 5
stty < /dev/cua3 -ixon -ixoff -ixany crtscts
The first tells Linux about the intrrupt, the third sets up serial
port defaults. The second causes IRQ5 to get a higher priority (actually
the highest priority) than other interrupts so we won't have massive
i/o errors. If you want/need to use irqtune you'll have to download it,
as it doesn't seem to come with RH. Irqtune can be found at:
http://www.best.com/~cae/irqtune/irqtune.tgz
You'll know if you need it--you'll get massive data corruption, horribly
slow thruput under PPP because many packets will get damaged and require
a resend. note that this does not sound like the problem you're describing,
but you may encounter this problem later, after solving the one you've
got now.
Good luck!

Subject: Networking and Kernel problem
Date: 15 Feb 1999 00:27:50 PST
The following problem seems to be some kind of networking/kernel problem.
I have RH5.2 on two different PCs with the same PCI ethernet card (intel)
running perfectly using eepro100 loadable module.
The first computer has all IDEs, and also win95 besides RH5.2.
The second which is scsi, has had win95 and now NT running, besides RH5.2.
>From the second computer which now has NT also installed, I took out the
card, and then put it back. There was some change of system resources in
the plug and play, ie reassignment as a result.
Win95 had to be reinstalled for other reasons and then NT was put on top
of it. When win95 was installed it overwrote lilo. I did not make a rescue
floppy when 5.2 was installed on the second computer. So I tried to boot
and mount root using the install floppy, which would not mount root as it
was scsi disk. So a hack was done. An image copy of the install floppy was
made, and the system was booted from another scsi with 2 years old linux
kernel from a slackware installation. The initrd from the non-booting scsi
system was then copied onto the copy of the image of install floppy and
the system rebooted using the new install floppy with the following
commandline argument
vmlinuz single root=/dev/sda1 initrd=initrd.img
It booted and mounted the root and lilo was run to fix the problem. Good
enough.
Now the problem is that the ethernet card does not run. There is no reason
that it should not, since nothing was changed on the system other than
this hack on the install floppy to mount the root and lilo.conf was
changed to accomodate the new 95 partition. The hardware is good as
swapping with the other computer confirms.
I have tried the following investigations and diagnosis to see if modules
load correctl.
lsmod shows that the module is not loaded.
If I load using
insmod eepro100
still pinging does not work, not even pinging to itself using the ip
address.
Note that the card _is_ properly probed as the file
/proc/pci
would show the irq, card and so on, consistent with the boot bios messages
about the PCI/PNP IRQS and Win95/NT system manager entries. But during
boot dmesg does not show any probing info while the other computer does.
Please help!!!!

Idea but no solution.
First, suggest you go to one of the Netscape mailing lists,
snews://secnews.netscape.com/netscape.communicator.unix
news://news.mozilla.org/netscape.public.general
I've seen some discussion that adding or removing files from either your
user config or Netscape install libraries may help. Check the following
URL (I can't reach the server right now) and associated discussion.
There are some links to SVLUG discussion which may help as well

I've had generally excellent luck with my desktop's filesystems -- 6 GB
in use for up to almost two years. Occaisional disk errors, nothing
(yet) that fsck couldn't fix. fsck (or e2fsck) is Linux's answer to
SCANDISK.EXE, BTW.
OTOH, I've had spectacularly bad luck on a laptop -- Linux just isn't
very happy, and filesystem errors play a large role. I've similarly had
a hell of a time with a Jaz drive under Linux -- same SCSI card as two
of my HDs, no end of trouble. I'm given to understand that there are
hardware incompatibilities, and tunable parameters (both filesystem and
kernel) which may minimize conflicts.
It would be helpful if you could be more specific on the type of drive,
controller card (if any), and specific error messages you are having.
I'm not hard-core hardware nut myself, but those who are out there could
get much better mileage with this information. Searching in web
directories (Alta Vista, Deja News) for the text strings occuring in
your error messages should also be fruitful. You should also check the
Linux Hardware Compatibility List (search for it, I don't have the URL
memorized) to see if there are any issues mentioned for your specific
hardware configuration.
