Subject: can't get past REMOUNT again!
It's happened again; I think it has something to do with mtab. Anyway, the
boot halts (in Mandrake 7.0) at the point where the boot process is
'remounting filesystems for read/write'.
I've created another partition on the HD and can e2fsck the problem
partition and everything's clean.
I got past it before but I can't recall how exactly -- I believe I started
a reinstall but then aborted it, in short, a very risky procedure.
(a) What is the problem?
(b) How can I solve it? <--priority question!
Thank God the HD is big and has a lot of empty space; I could do a small
install and salvage a document I need to edit by 6:00 p.m. today!
I'd _really_ appreciate some insights!

yeah, i think there is something odd with that drive. i have one, and
it won't cooperate with my adaptec scsi card. it sends the card into
endless rescans of the scsi bus on bootup or module insertion. it
will work with a tekram 315, but i get strange messages about dma
interrupts. all this has me thinking the drive is just a hunk of
shit. for those of you out there thinking about a cdr, stay clear of
this one.

Hi, whenever I try to run SSH on my box it tells me this:

Turning on the -v option doesn't tell me anything extra, or at least the

I don't really know what the problem is here - scp works fine, as does
ssh if I issue a command afterwards - for instance, 'ssh

with just logging the user in via the login command, but I don't know
why that would have stopped working... Any help is greatly appreciated

Subject: Questions about qmail
Date: Thu, 09 Nov 2000 12:03:14 GMT
Hi,
I don't understanding what to do for creating users using qmail (of
course after reading FAQ and Man pages).
My installation of qmail is based on RPMs on RH6.2.
It is mentionned in DOC that /var/qmail/users must contains several
files, but in my case there is no things, I dont have elsewhere
directory like rc as mentionned in DOC (however in the install I making:
cd /var/qmail/defaultdelivery
cp -f mdir rc , no error was mentionned), this is the alone reference to
rc. Note also that file ../users/assign does not exist, this is also the
case for smtproutes file.
In /var/qmail/control I creating files: defaultdomain, defaulthost,
locals, me, rcphosts and configured them as mentionned in the DOC.
- Test delivring morks fine for external addresses, but not when I send
to myself the same message (echo to: [EMAIL PROTECTED] ...).
In my /Maildir/new, I can read the error: Sorry can not find any host
named mydomaine.mydomaine.com. (#5.1.2).
- Test for receiving:
telnet 127.0.0.1 25
220 mymachine.mydomaine ESTMP
then I tape: HELLO myname and press Return, but I got the error message:
502 unimplemented (#5.5.1)
Who can helps me to fixe this?
Escuse me in advance this is my first expérience with mail servers!!

Hello TCS,
While ideally, setting it as high as possible doesn't really matter much
as you say, I can tell you that setting it too high when running PPPoE can
be a nightmare. I am using my Linux box to firewall and share my DSL
connection and it is setup by PPPoE with 1492 as the MTU.
When I first connected it, with my Windows box setup with 1500, the
Windows machine was crawling..! After I lowering it to 1412, things are
much better. FWIW, I still don't think it's quite up to par, but I'm
still tweaking it. I'm still in the "new toy" phase..! ;-)

Subject: Was: Software RAID
Date: Thu, 09 Nov 2000 14:40:40 +0100
Seems to be that there are several people having experience with
software RAID.
So, let's be a bit more detailed.
Since one week i'm trying hard to get RAID5 to work.
The System is a netfinity server with 2 Pentium III/933MHz, 2GB RAM and
5 SCSI hd's. On 4 disk i created identicall partitions, each about 8GB.
The first three shall be for working and the fourth as spare.
Creating the array wasn't a problem, also the mke2fs completed w/o
errors. But when i try to copy some data to the array the system
crashes. All i get are EXT2fs errors in block allocation. This happens
under kernel 2.2.17, 2.2.17, 2.3.40, 2.4.0-test9 and 2.4.0-test10.
Always the same errors.
Is there a trick about ext2fs?? I upgraded to the newest ext2fs-tools,
but no change :..-((
Can anybody help me?

I find that RedHat 6.2 installs, configures and syncs RAID-1 devices
quite nicely. On /boot and / . I have used both the graphical
install and kickstart.

use a linux bootfloppy and run `fdisk /dev/hda`.
remove all partitions. (you can't use DOS FDISK, it cannot handle linux
partitions)
then run FDISK.EXE \mbr from a DOS bootfloppy (you can't use linux'
fdisk for this)
That should solve all the problems.

Hi Cindy,
boot from a DOS boot disk and use the fdisk programm to remove all the
partitions including the non dos partitions.
After that you'll have to format the drive again.
Hope that helps.

What does lilo.conf contain?
Is there a reference in it to hdc?
And `rdev` does it point to the right device?
Does your BIOS boot from hda? or hdc?
so many questions I have, if you can answer some, maybe I can help more.

My qmail (v 1.03) is installed on Slackware4.0, but is probably applicable.
Look in the ./qmail/man/cat5 or ./qmail/man/man5 directory for the man page
qmail-users. It tells you the structure for the 'assign' file which you make
with an ascii editor to put into the ./qmail/users directory.
It also tells you that until you run ./qmail/bin/qmail-newu the users you
have put into the 'assign' file will not be active, so you run the program
and it will create ./qmail/users/cdb which qmail will use for distributing
the mail.
Hope this helps a little. ...Edwin

Subject: Linux firewalls
Date: Thu, 9 Nov 2000 06:53:22 -0800
I am setting up a webserver and FTP server for a friend on the a single
machine, (a dual-homed Bastion Host). It will use Redhat Linux, Apache
Webserver, WU-FTP, and ipchains. There will be a perimeter network, followed
by an internal choke firewall (another Linux box, but only with
packet-filtering and no services). I am learning the software but am not yet
familiar with the the various holes in setting it all up, so:
QUESTIONS:
1) You can install Apache by itself, or else with PERL, PHP, Java, SSL, etc.
Do these additional things open up big fat holes or are they basically
pretty safe to run on a Bastion Host?
2) I have installed WU-FTP and locked down a user account by chrooting it
and setting appropriate permissions to folders. I have blocked uploads. But
someone told me to use a "special ls command" that is different from the
regular Linux "ls" command, because it would be more secure. I realize that
the latest version of wu-ftp actually has its own "ls" command built in, but
is there some other "ls" version that people commonly use in ftp? Can anyone
give
me more info?
3) I want to set up NAT for this person so that anyone in his office can
attach to the internet via a single Linux box on a DSL line. This only
requires 5 lines in ipchains (I am running it right now), causing the Linux
box to perform Network Address Translation on all TCP packets that arrive at
its door. Alternatively, I could do NAT for just a few things (ie: SMTP
mail, HTTP, etc, and not allow NAT on anything else). If I decide to NAT
everything, and block anything arriving at the firewall from the internet
that doesn't have an ACK in the packet, then is this not safe? Wouldn't this
mean that only people from inside the firewall could be running sessions
that are done via NAT, but people outside the firewall couldn't do anything?
My objective is to keep it simple for myself to set up, yet secure. It would
be much better to NAT everything, because then in future whatever he tries
to access will be available from the inside of the firewall, and I wouldn't
have to come back to "punch holes" in the firewall.
4) I want to set up a PPTP VPN with SSH for this person so they or I can
dial in and maintain things, or copy files back and forth. How secure is it
to use PPTP and SSH on a firewall? Is this considered relatively secure or
relatively stupid?
Thanks,
Firewall Newbie,
Micer
