Could anyone offer some advice as to how I could install linux
(distribution such as Red Hat lets say...) on a 486 with only 4MB of RAM?
This system has a non-bootable CDrom and several-hundred (1-200) MB hard
disk space...

That is how I do run it. I.e., my hardware clock does run UTC.

I could not find anything in the cron documentation that specifically
addresses this issue. I did not examine the source code for cron. I
assume that, usually, crond examines the various cron tables once a
minute and acts accordingly. Since these tables are all in local time,
not UTC, they act as I expect (but never thought about before). And if it
says to run something at 1:03, that is what it does, whether or not a
given day (such as yesterday) has two 1:03 AMs or not.
BTW, my /etc/crontab does not start anything between 1AM and 3AM on
Sundays anymore (do not want to skip anything in the spring advance to
EDST).

Date: Mon, 30 Oct 2000 13:11:10 GMT
HI all,
I have setup ipchains and various firewalls with linux and think it
works great, but now I would like to setup a router and would like to
know the BEST source of info on the topic.
I have used full linux and a LinuxRouterProject floppy and would like to
setup a router which would connect 2 gateways to a LAN. If the user
wanted general internet services the router would point the packets to
GW1 but if the users wanted to connect to one specific service, the
packets would go to GW2 over a dedicated ISDN line.
I am not even sure that the LRP Floppy could accomplish this, but if it
could I would love to know some sites and/or information on this.
If I should use a full install of linux I would love to know the best
source of info for this as well.
I have NO knowledge of setting up a linux router with static tables so
please if you know of some idiot sites/info... that would probably be
best for me.
thanks all
PS Is this going to be an incredibly daunting task?

Subject: Problem with added memory
Date: Mon, 30 Oct 2000 13:19:56 GMT
I just installed more memory into my computer, do
I really have to recompile the kernel for the
added memory to take effect?
Previously I had 64M, and I put in another 64M,
and added the 'ramdisk...' line in lilo.conf:
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
prompt
timeout=50
linear
default=linux
vga=791
image=/boot/vmlinuz-2.2.14-5.0
label=linux
read-only
ramdisk=128
root=/dev/hda8
I also tried to have the ramdisk entry in the
general part of lilo.conf. When I run top I can
see that the system is still running on 64M of
memory. So, back to the question, what do I have
to do to add the extra 64M to the system?
Thnx for any help!

There are distributions for very small systems. Tiny Linux is one of them
as far as I know.

you have to use something like append="mem=128M" (check exact syntax in the
man pages of lilo.conf)
Ramdisk enables you to use part of the memory as harddisk, and that is not
what you want.
Good luck,

Linux's read-only NTFS support isn't that flaky in my experience,
although I've not used it much. My first guess is that the problem is
because RH tends to use heavily patched kernels. (I assume from the "-3"
at the end of the kernel number that you're using an RH-supplied
kernel.) It's possible that some patch RH has applied has broken NTFS
support. You may therefore want to try downloading a "pure" kernel
(check http://www.kernel.org) and compiling the whole thing. This will
be more work than just compiling one module, but it's something that,
IMHO, every Linux administrator should be able to do.
Another possibility is that there's a problem with your NTFS partition;
maybe it's become corrupt. It could also be that my failure to encounter
such serious problems just reflects good luck on my part.

The experimental read/write version adds experimental read/write code.
AFAIK, there are no differences in the read support. From what I've
heard, the write support is *VERY* flaky, so I wouldn't suggest you use
it unless you intend to debug it and contribute to development.

Look at www.linux.org under distributions. Peanut Linux is another option.

I found out that few lines were missing from /etc/inittab
1:2345:respawn ...........mingetty tty1
2:2345:respawn ...........mingetty tty2
.....................................................
6:2345:respawn ...........mingetty tty6
Editing the /etc/inittab file and adding the above worked.
However each time I ran Xconfigurator, the system fails.
Just before restart I will check /etc/inittab only to find that
the above have been deleted again. If I don't run Xconfigurator,
my linux is fine (INIT 3). Later on I was getting errors such as
the system is full. ie I couldn't append /etc/inittab anymore
"df" command revealed that my root dir / had 141MB used
out of a total of 141MB. Under normal circumstance its 17MB
out of 141MB used. What's caused it to grow to this size?
My 2.5GB Linux partition consists of /, /var, /usr, /users and
120MB SWAP.

Oddly enough, I happened to read the man page for cron the other day
for unrelated reasons (I was seeing if it was worth installing anacron
or not, and in my case it was). That says:

So it sounds like you need a better cron. Mine seems to be Vixie cron
v3.0pl1, as packaged in Debian potato. However, the key change seems
to be this patch which was applied:

So you probably need to either switch to Debian :-), or hassle whoever
is responsible for your cron package to add something similar.

Or you could do that. :-)

Is there a way to change the time automatically for daylight savings for
Linux? I had to swallow my pride and boot into windoze98 to get the right
time. I know there is also a Unix command to change time. Does anyone know
what is that command?

man clock
man hwclock
man date
man rdate (or maybe netdate)
It is easy to do. You can combine rdate (sets time from a remote
timeserver) with hwclock to set both system/linux time, and the BIOS
clock automatically every time you boot, or when you connect via PPP, or
via cron at intervals or whatever scheme you want.
List of published time servers:
http://www.eecis.udel.edu/~mills/ntp/clock2.htm
Script excerpt:
/usr/bin/rdate -s $SERVER
## set hardware clock with our new time ...
/sbin/hwclock --systohc
But curiously, Linux has always automatically handled the time change
for me. I was sitting here at 2:00AM Sun, and watched the clock on my
desktop jump to 1:00AM. No user intervention. I have no idea where/how
this gets done though. But a nice trick.

Subject: Newbie can connect to ISP but not browse...
Date: Mon, 30 Oct 2000 15:05:32 GMT
I've recently completed the RH6.2 install (semi) successfully. During the
installation process I chose the server install because I want to be able to
use this machine as an FTP server and such and as far as I could tell from
the documentation the Workstation install left out some networking
capability which I may want. My problem is I can connect to my ISP via KPPP
(I have KDE installed) with no problems but when I bring up Netscape or any
mail client I just get an error message stating some like 'can't resolve
hostname' or something to that effect (I'm not at that PC now so I'm not
sure of the exact working of the message). During the installation I chose
DHCP and didn't specify any IP/Gateway/DNS entries so I'm assuming this is
likely part of my problem. Can anyone point me to some good info on the
RH6.2 server install and network configuration?
In addition - where do I configure my user priveleges, the non-root user I
created during the install process doesn't have privelege to do much. Where
can I find some 'standard' settings for non-root admin? I'm doing most of
the package installations/configuration as root but I would like to use
another user if possible.
Sorry if these questions are vague - I'm new to Linux...but having a good
time learning.
