But that is the problem, there is no evaluation-7.1.iso there. There is only
the live eval which runs from the cd and does not install at all.
Not a viable working copy.
Looks contrary to the open source philosophy don't you think?

BRU supply a tool, CRU that writes OBDR tapes and I use that. To be
sure that OBDR works, though, I would have to zap a lot of my hard
drives (especially the boot block) so that it would be impossible to
boot my machine from there so that it would try to treat my C1599A
DDS-2 tape as a CD-ROM. I have not had the nerve to get around to
trying that. I do write an OBDR tape each month, but I have also
written the two floppies so I can use those tapes even if the OBDR
feature does not work. If I had two spare hard drives, I just might
try it, but I do not. I have a sort-of spare machine, but it is much
too small to do OBDR on, and it does not have a DDS-2 OBDR drive on
it. What I should do is buy another machine like this one and try to
install by doing an OBDR recovery. But I do not have the money or the
space for yet another machine.

I do not care for that philosophy. Reminds me too much of the Bill
Gates philosopy. That would just result in too many re-installs. I
normally try to find out the cause of a problem, so I need solve it
only once instead of over-and-over-again. YMMV.

I have never gotten this from Netscape, though I shut it down when I
do not use it. I leave Linux up 24/7 if I can. The only times I cannot
is when the power goes down for over 1/2 hour and my UPS poops out, or
when a disk or tape drive locks up with a process in D status. This
does not usually crash the system, but only a reboot will get the
recalcitrant process off and the file unlocked.
I never got SysRq to work, since I do not know how to get it to give
me enough control to activate it. Apparently the trick is to
anticipate the lockup and do have at set it off afterwards.
When my X server quits that bad, and C-A-Bs or C-A-PF[1-6] do not
work, I go to my other machine and ssh into this one, then do init 3
(to get X really off), and init 5, and then it is back up. Unless the
kernel really crashed; I think that happens only about 2x per year.

It seems to me that you should need to be root only to INSTALL a
kernel. Anyone with permission to write in /usr/src/linux-[release]
should be able to build one.

I think this is caused by not having an initrd file for the new kernel.
At the lilo prompt enter "linux root=/dev/hdaX" where hdaX is the
correct root partition. If it boots like it should then you can make an
initrd image.
mkinitrd /boot/initrd-2.2.xx.img 2.2.xx
Also be sure you have an initrd line in /etc/lilo.conf
label=linux
initrd=/boot/initrd-2.2.xx.img
Hope this helps.

Date: Fri, 09 Mar 2001 18:30:03 -0000
I installed SuSE lunux 7.0 on my Home PC but am unable to access the net.
I have an cable modem connection from @Home.
The YaST2 utility which comes with this version of SuSE is able to lacate
the Cable Modem hardware but is not able to get an IP address from the
@Home server. As the @Home service uses DHCP to assign I.P. address I
changed the dhclient.conf file to add the DHCP client ID but when I try to
start dhclient in give me an error saying :-
SIOCSIFFLAGS : No such device.
and stops after a few try saying no offer received.
I have no idea what those strange sequence of characters stand for and why
the linux dhcp client is not able to generate the IP when the windows dhcp
which is provided on the @HOME CD is able to do so.
Please advice.
Thanks in advance.

When netscape is launched, it creates ~/.netscape/lock file and If you do
not gracefully shutdown the netscape, the ~/.netscape/lock file remains
there and if you relaunch the netscape, you will get such a warning
message. The only way I know of getting rid off such a message is to make
sure the netscape is gracefully shutdown or else manually remove the
~/.netscape/lock file.

Hi.
I'm trying to use IRC on my Mandrake 7 box (7.2 I believe). When I try to
connect to a server, it says I have to run identd. I'm running identd on my
machine.
I'm behind a firewall, which is another Linux box (Mandrake again) using
ipchains. It is also running identd. The user I'm using on my machine is not on
the firewall.
Is there some setup required for identd? Is there a special command I need
for ipchains to allow the IRC server to access my identd? When the IRC server
asks for an Ident, does it stop at the firewall,so do I have to have my username
on the firewall (I REALLY don't want to!)

OK, did that. Issuing "linux root=/dev/sda1" gets me the same thing.
On a hunch, I tried issuing "linux init=/dev/sa1" but didn't get anywhere
with that either.
I tried running the mkinitrd command anyway, only to be told that I don't
have any loopback devices. I tried recompiling the kernel and enabling
loopback devices; however, I got the same thing - no init found. Seems
like a chicken/egg thingie here.
So, here's what I'm going to do: Completely disable modules, ensure the
nic and scsi are built into the kernel, with loopback devices. Lets
see where that gets me.
Any other ideas that you think I should try?
Thanks for your help.
