Date: Tue, 8 May 2001 12:07:33 -0700
Hello,
I am trying to install RedHat 7.1 on an HP Vectra XU 6/200 and am having
trouble.
This system has an Adaptec AIC-7880 controller on the motherboard that has
the CD-ROM connected to it. It also has an Adaptec AHA-2940W/UW PCI SCSI
card that has a Seagate ST32550W drive connected to it.
The install seems to go fine, it sees the disk, allows me to partition it
and loads the OS. It won't boot from the CD, but it will from a boot
floppy. After the install, the system goes thru the BIOS startup and I get
errors on the 2940W controller
SCSI termination not found
SCSI BIOS not installed
I then get .... Insert system diskette in drive. Press any key to continue
Using the boot floppy from the install I get the following error
could not find kernel image: linux
This is my first attempt to install Linux on a system with SCSI so any help
would be appreciated.
Thanks
Jon Page

How about looking here for info
http://www.linuxdoc.org/HOWTO/Adv-Routing-HOWTO-10.htm
also in there is the url:
http://netfilter.filewatcher.org/
I would stay looking at linuxdoc.org is the first place to
start.

Letting off a little steam can be a good thing. Keep at it! Netfilter
is not that hard, you just need to give it a little time to absorb
(and forget about ipchains).

Date: Tue, 08 May 2001 22:51:47 GMT
Well a few short nights later I can say the following :
1�. Installing a second laptop with a very similar environment didn't
raise the issue of having trouble booting. It must therefore be an issue
of lilo. However as none raised errors in my lilo.conf I beleive the
issue must reside somewhere else.
I can also say that I ran many (many) times the lilo tomake sure my
lilo.conf was well written. Sounds thus there is an issue in my
lilo.conf but none raised it & I can't see any.
2�. To recover the full PC (mean the two OSes) I did a recovery install
of WIN2000 & managed to run a prompt executable that the recovery
install proposes (CLEANMBR). This sort out the problem but doesn't say
what bothers Win2000 on my machine.
My personnal gess is that the TOSHIBA Satellite Pro 4300 has some issues
with the different startup phases as a know bug seem the lost of
accessibility of the BIOS while changing the order the different devices
are used to boot. I set up the bios for the following : cd-rom -->
floppy --> IDE0, but it today (after an install of Win2000) boots in the
following Floppy --> IDE0 --> CD-ROM (which is pointless).

It does not?
Well, I have SuSE 7.1 installed, that uses a 2.4.0 Kernel and it supports
ipchains without problems, after you installed the module for it.
One simple "modprobe ipchains" and the problem was gone.
I think we are both in a similar situation:
One PC with Internet connection should work as Router (with MASQ, because we
only have one public IP address), to give a whole private network of PCs
Internet access as well...right?
Right now I'm building a LFS system on my router and the post you are reading
right now was sent to you through this router, currently working with ipchains.
(to be more precisely: I'm typing this while GCC compiles GLIBC, operated
through SSH access from my workstation...geeez, that takes forever, even on a
550 MHz machine with 128 MB RAM)
> Ipchains is not much use to me if I can't use ftp!
I can and I don't have any FTP module installed.
I downloaded plenty of source code of FTP servers today, using WGET.
On my Windows machine I had to enable PASV for all FTP clients to work, but
after I've done that, everything was working fine, without ip_masq_ftp
installed (I guess WGET uses PASV as standard setting).
> So I made it my mission to learn iptables
That will be my next problem. Once my new LFS system is running, I will have to
write some really good forwarding filters, after all the system should be
secure as well.
(right now everything is widely open, I guess a good hacker would have root
access within 15 minutes ^_^ But I had no choice, I needed Internet access to
get those source packages).

Good question.
I was browsing the WEB for about one hour today, finding nearly nothing of
interest, except one page.
I don't know if this one is helpful (I had no time to read it so far), but it
looked good, so I bookmarked it.
It may not exactly meet your expectations (personally I believe your Linux
knowledge is far beyond my horizon), but maybe it is at least a bit helpful:
http://www.boingworld.com/workshops/linux/iptables-tutorial/
> I know that I cannot be the only one frustrated with this.
Probably not...but right now I would be already happy if I could compile
FileUtils 4.0, but GCC just refuses to compile it, because
"macro 'strndup' used without args"!??
Oh, I see GLIBC is ready...finally.
Time to go on.
Good luck for your quest.

Subject: Re: RH7.1 - Can't telnet or SSH in from another host
Date: Wed, 9 May 2001 02:07:51 +0200
several points to check:
1) is your network ok? can you ping from one computer to other (on both
sides)? don't use names just IP addresses.
If you can't, fix this first.
2) telnet and ssh don't work the same way on RH systems (telnet is fired
from xinetd while ssh is a standalone server).
3) login as a non root user on the server pc. Then try to telnet to the very
same pc you are on : telnet localhost. If you can't there may be a problem
with your telnet server. On RH 7.1 you need to install two packages:
telnet-0.17-10 (client) AND telnet-server-0.17-10 (server) are they both
installed? Don't worry with /etc/hosts.allow /etc/hosts.deny from straight
distro, they are both empty (just comments), and that's what you need. Check
that /etc/xinetd.d/telnet in not disabled - It was not in 7.0 but now it is
in 7.1 though a comment still says "# default: on" ! You should replace last
line "disable = yes" by disable = no". Now you must reload xinetd daemon so
it takes care of your change: "/etc/init.d/xinetd reload" (or "restart"). By
the way, check xinetd will run at start-up: "/sbin/chkconfig --list xinetd"
it should be "on" at level 3, 4 and 5.
Now you can try to telnet locally. Don't try to log as root. It's not
allowed by default, and not a good idea to change this if you are not on a
_very_ secured network: You will send clear root password, that can be
sniffed easily.
4) now ssh. it is not filtered by xinetd daemon. So you check that it's on:
"chkconfig --list sshd" it should be on at level 2, 3, 4 and 5.
Check it is running "/etc/init.d/sshd status" if not then "/etc/init.d/sshd
start". It may compute a host key at first time. Now try to ssh to local
host. it may ask you to accept a host key. Just say "yes". Then you have ssh
OK (kindof a secured telnet) You can use it to "telnet" from a remote host,
because password aren't sent thru network. An encrypted protocol is use
instead. You can configure some files in ~/.ssh so you won't be asked your
password to connect, everytime. Read the "man ssh". By th way, there is a
good ssh client for windows freely downloadable from www.ssh.com. It can do
file transfer (sftp) too "a la Cute-FTP" from Windows (drag and drop). Good
Luck!

The only time I've seen this happen is when I've burned a multisession
CD incorrectly (bad options to mkisofs, etc.) If the CD-writing
software used doesn't close the session properly, weird things could
happen, including not being able to see all the sessions. Some
commercial CD-writing software is of... questionable quality, and may do
that.
I have heard that Joliet extensions are not quite compatible with
multi-session CDs, but am not sure whether to believe it or not.
(experiment coming up later on...) I have also noticed that many CD-RWs
will not recognize a session you've just burned unless you eject the CD
and re-insert it.
Kernel 2.4.3, eh? What does kernel 2.2.x do?
