Subject: can't read mounted fd0 or hda1
From: Allan Adler <[EMAIL PROTECTED]>
Date: 16 May 2001 02:03:17 -0400
I have Redhat 6.2 on a Dell laptop. It is an isolated machine that used
to be on a network. The hard drive has a dos partition on hda1 and
linux on hda3 and hda6. I can mount the floppy drive fd0 and
dos partition. The command df correctly shows the amount of
few space on them. However, when I try to list directories with ls
or look at individual files on them, I get a segmentation fault.
There is nothing wrong with either the dos partition (which has
windows on it) or the floppy drive. The way I know that is that
from LILO I can boot up the dos partition (which has windows on it)
and from windows I can read directories and files on the floppy drive
and copy them to the dos partition.
I should also mention that I was able to read both hda1 and fd0
under linux a few months ago. The question is, what did I do to
screw up the system since then? The only thing I can think of is
having used something like netconfig or nettool to try to remove
some network stuff from the network the laptop used to be on. I didn't
know what I was doing and was removing the stuff under an incorrect
assumption about a problem I was having with dialout. That assumption
was based on experience with an earlier problem with dialout that in
fact *was* caused by the network configuration of the laptop.
My guess is that the way network stuff is configured on the laptop
affects the way the laptop communicates with certain peripherals.
That was the case when I first had trouble with dialout. I suspect that
it is likewise the reason linux can't read hda1 or fd0 when they are
mounted. The fact that it can mount them and that df gives correct
information about free space on them merely means that linux has
some other way of doing those things, but actually reading directories
or files on them must involve some network stuff. I think it does that
using pcmcia. I don't know much about it. Anyway, that's my latest
theory about it.
If anyone knows what the problem might be and how to analyze and
solve it, please let me know. Thanks.

Oops. I had originally tried the linuxcar solution with tty6. I just
tried it with tty1 and it works. Still gives the message "bash: no job
control in this shell", but I guess it's just informational.

Is your hosts.allow set to just

or is it set to
ALL:ALL
The latter is the proper setting for this.

I'm by far no mail expert, but I believe you'll need to use something like
fetchmail in order to pull down your mail from your ISP, if this is what
you mean. Using sendmail does just that, it sends the mail. From what I
understand, qmail has the ability to both send and receive mail. Someone
please correct me if I'm mistaken. On my system for my little LAN, I use
sendmail to send out all the other users mail, and fetchmail to pull it all
in and store it for each user.

Hey Brian,
>From what I understand, the assignment of which NIC gets eth0 and which one
gets eth1 has to do with their placement on the PCI bus. For example, in
most cases, from the top down in your computer, the first NIC in PCI slot 0
would get eth0, the next eth1, etc. Now, it would seem that since your
second NIC is an ISA card, it is looked at last every time, meaning it will
always be assigned as eth1. And, since your built in NIC is most likely
sitting on the PCI bus, and isn't actually in a slot, it is probably always
going to be seen as the first device on the PCI bus. One thing you may try
is to put in a 2nd NIC (a PCI one) and see whether choosing the different
available slots you have left allows that card to be recognized as eth0. Of
course, the last option would be to disable the built in NIC, and use 2 NIC
cards that you can put in whichever position suits you (but I'm sure you've
already considered that...).
Good Luck!

Subject: mounting problems (must be superuser)
Date: Wed, 16 May 2001 17:41:26 +1000
Hi,
I'm using Looplinux (ie looplinux file on win partition, with slackware
packages) with KDE.
I'm having problems mounting floppies and cdroms, it says I need to be
superuser to mount. I've tried the KDE desktop links to the floopy & cdrom,
and programs like Kwikdisk, and also on the console, but they all give this
message. My fstab file looks like this:

Also, I'm having some problems with KDE itself. One is that the child panel
doesnt preserve its icons (after I log out and log back in) and also, in
dialog boxes, when I list a directory in detailed view, and I press on
Modified (for example) to see it sorted according to the date the files were
modified, the dialog box wont sort them.
Any help is appreciated.
P.S. I am using the latest KDE (installed from the latest Slackware
packages, a few days ago).
Thanx.

Subject: Kernel upgrade (patch) ???
Date: Wed, 16 May 2001 09:53:07 +0200
Let's say I've modified my kernel, so as to exclude SCSI support, IrDA
support, and a lot of other small things.
Imagine this is kernel-2.2.18
I want to patch this kernel to 2.2.19. Would the patch program work
correctly? Patch only the pieces of code that is in the kernel? Or do you
need an exact copy of the previous Linux kernel source tree?
Just a thought...

I have not found to date a precise explination of the kernel map

Hum...It appears that the software works by either halting the
CPU, or, throttling it back so it runs slower. Linux does neither of
these things, AFAIK...so since the CPU is running all the time, and,
at full speed, of COURSE it will be a bit warmer.
Unless you are overclocking and the temperatures are getting
seriously hot, though, I would suggest a bigger heatsink and better
fans. Shucks...now that I think about it...I would suggest that
anyway. It seems kind of silly to me to go to the work of getting a
fast processor, or overclocking to get more speed, then, throttling
back/stopping the processor. Kind of like buying a Porsche and only
driving it in the first couple of gears.....

I had the same type of problem with 2 network cards. I had one that I
wanted to use for my internal network and one for going out to a cable
modem. They are both PCI but one always loaded first when I set up the
machine no matter which slot I put it in. The way I got aroung it was to use Linuxconf
and simply
reassigne the first card from eth0 to eth1 and then the next one eth1 to eth0. When I
rebooted the machine that is the way it stayed.
