Re: [expert] Choosing the right filesystem

[Sridhar Dhanapalan]

Actually, ext3 is almost a total rewrite. While ext2 was designed with various
'hooks' which allows extra functionality via 'plug-ins' (including on-the-fly
compression and journalling), the ext3 designers thought it best to start
afresh. Ext2 is still a very good filesystem, with an elegant design. It made
sense to make ext3 in a similar fashion.That being the case, it also made sense
to make it backward-compatible with ext2.

While generally being the slowest FS, ext3 has one advantage over the others:
data integrity. With ext3, you have the choice of having no journalling (for
maximum speed; just like ext2), metadata journalling (like ReiserFS, XFS and
JFS) or even data journalling (for maximum data integrity, at the expense of
speed). The third option, data journalling, is available only to ext3, and makes
it a far more reliable FS than the others.

I personally use ReiserFS on my home system. I've had a single 10GB partition
for all my data (my drive is too small to make multiple partitions very
practicable) for about a year now, and my system has recovered flawlessly from
numerous crashes and outages. I use ReiserFS 3.5, which was the latest when I
created the partition, which I am told is a little better than the latest today,
3.6.

Re: [expert] Choosing the right filesystem

[Sridhar Dhanapalan]

ACLs can add increased safety and security to a filesystem, by controlling what
can be accessed by whom. NTFS has this feature, and so does XFS. Samba can use
XFS's ACL feature to link to NTFS's.

Another reason is that ReiserFS has historically had problems with NFS. This
apparently has been corrected, though.

All,

   To the developers at Mandrake Kudo's all around.  I just did the Fvh
update of php due to the security problem on my all my Mandrake boxes and
one of my RH boxes.  The update on 7.1 Mandrake went flawlessly as well as
8.1.  I'll be a couple of hours fixing the RH box.  *grin* and kudos all
around. (it broke mod_php on 7.1 RH)

jonathan,

there are a lot gui tools that do what can be done at command line,
and they make life easier. but, what do you do when you are using a
system that does not have a gui tool that you are used to using?

you sit with a lost look on your face because you can not do what
ever it is that you have done with gui.

same can happen when doing diskette copies.

for a quick and easy coping of diskettes;

to copy from diskette,
  dd bs=5120 /tmp/out.file
or
  dd if=/dev/fd0 ibs=5120 of=/tmp/out.file obs=5120

to copy to diskette,
  dd bs=5120 /dev/fd0
or
  dd if=/tmp/out.file ibs=5120 of=/dev/fd0 obs=5120

using if= and of= will make copies a little faster.
  
dd is found on most all linux/unix systems. a gui has to installed.

Re: [expert] DHCP Server + DHCP Client

Mike if I understand you correctly I need to add.

option subnet-mask 255.255.255.0;
option broadcast-address 12.234.130.255;

Now the question comes.  What happens if the subnet I'm on from my ISP
changes?  Gateway and subnet have changed twice since the @home fiasco.

Now to sorta answer my own question the dhcpd -q eth1 solved the problem
it starts and only looks at the internal nic.  Thanks loads for the help.

[expert] Destination Host Unreachable

[Albert E. Whale]

I just completed the Installation of LM 8.1 on a Server which has run LM
for 5 Years.  The Interfaces in use are

eth0: 3cSoOHO100-TX Hurricane - Module: 3c59x
eth1: 3c905B Cyclone - module: 3c59x

As I test out the Network interfaces, there appears to a communications
problem with the Network.  Hmmm, 2 hours ago, this server was working.
Right now I am gatewayed via another LM 8.1 Server with two 3c905B
controller cards using module 3c59x.

Is there a problem with the Hurricane Ethernet Cards and 2.4.8?

Re: [expert] Help - Stuck at '...kernel params..' - SOLVED ???

[Ashley Moore]

yeah, now that you mentioned it once before when I've moved the box,
the BIOS complained about HDD being absent. Just opening the cover and
pressing the HDD cables in place seemed to make the problem go away! 

its too scary I'm going to stop at the store first thing to pick up
a replacement cable. (better safe, than sorry :)

tks,
Ashley.

Gotta admit, I still get the odd spam message; but I can still count'em on
one hand during any given week...  

My "crusade" now is to go after the ISP's who can't get their DNS right to
allow us to get mail from friends because of our tight anti-spam
filters...

For example, here's what rr.com is doing (sent this a few minutes ago :^)

I'm far from being a DNS or mailer expert; but I'm getting there despite
my desires to do other things...  :^)

Another thing that is helpful are the DNS services. They make it
possible to have a mailserver running on a machine that has a dynamic IP
address. I've been using one on my home machine now for almost a year.
It makes things quite nice, although the downside to being accessible is
that you have to worry about the spammers and such hitting your server.

It seems his is using iptables, and pmfirewall will only work with

pmfirewall doesn't use iptables. Besides, I used pmfirewall with Mandrake
7.2 and had the same problem.

The ISC DHCPd server configuration file *requires* a subnet
declaration for all networks represented on the box even if
addresses are not leased from some of them. Create an empty
subnet declaration (no range statement) for the network to
which eth0 is attached and you'll find the server daemon
will start. This will not interfere with dhcpcd on eth0 for
your cable/dsl setup because the declaration is empty -
without the range statement there is no pool of address from
which to lease. You can also, if you're worried about it,
specify on the command line when you start DHCPd that it
watch only eth1 if you want.

dhcpd -q eth1

I have exactly the same card, just do a 'modprobe via-rhine' and all will be 
well. I did have some issues with older mandrakes, never tried 7.2, but 8.0 
gave me loads of trouble, the MAC was all 0, but it works fine in 8.1/8.2

just put via-rhine in /etc/modules and it will be loaded on boot.

[expert] Xservers +bs?!?

Dear all,

I use my Mandrake 8.0 box for Image Processing applications and when I 
obscure a window the image disappears! According to the instruction 
manual I need to enable the backing-store.

These are the instructions: In file /use/lib/X11/xdm/Xservers I need to 
append '+bs' to the line starting ':0 local /usr/X11...'. So I now have:

# $XConsortium: Xserv.ws.cpp,v 1.3 93/09/28 14:30:30 gildea Exp $

1998/10/04 15:23:14 hohndel Exp $
#
# Xservers file, workstation prototype
#
# This file should contain an entry to start the server on the
# local display; if you have more than one display (not screen),
# you can add entries to the list (one per line).  If you also
# have some X terminals connected which do not support XDMCP,
# you can add them here as well.  Each X terminal line should
# look like:
# XTerminalName:0 foreign
#
:0 local /usr/X11R6/bin/X +bs -deferglyphs 16

Unfortunately, this does not seem to work! The images are still 
obscured. What am I doing wrong? Do I need to enable save-unders as well?

Any help would be appreciated.

[expert] Swap space was - Optimum partitioning

[J. Grant]

What are everyones opinions on the the swap issue? like If i have a 1GB 
swap partiion does it get fragmented? How does this get affected by the 
new VM in 2.4 kernels?

Does a larger swap file require more management and thus slows down a 
system if it is bigger than necessary?

[expert] How to enable authentication in Postfix?

With the new update of Postfix that was just released by Mandrake, I made 
sure to install it as well as the various libsasl .rpm files.  I just tried 
to connect (manually) to my mail port to see how it looked.  What I got 
was:

/home/davidg$ telnet {myhost} 25
Trying {my IP}...
Connected to {myhost}.
Escape character is '^]'.

[expert] D-Link DFE 530TX Network Card Install Error

[Craig Steffler]

I've got Mandrake 7.2 running on a Compaq AMD 475
I tried to install a D-Link Ethernet Card DFE-530TX+ and when I run the
insmod command in the /usr/src/linux
directory I get the error:
Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters

I tried searching the D-Link Site for Tech Support. It's pretty much
non-existent, not entirely unexpected.
Their instructions for linux are somewhat vague. All the SysAdmins I
know are less familiar with Mandrake or
haven't done that many network card installs in some time.

I've noticed in the Linuxconf - Network Configuration the IO port and
IRQ entries at the bottom. Are they related?

I guess this is what I get for not sticking with that C class many moons
ago.

Thanks in advance to anyone who has a clue at what to do.
