[techtalk] hdparm and DMA "not permitted"

2001-05-20 Thread Conor Daly

Little problem here with hdparm and DMA.  I'm using an AMD K6-2 350MHz on
some kind of amibios mobo with "Ultra DMA Enabled" in CMOS but I cannot
set "using dma" for the drive(s).

[root]# /sbin/hdparm -d 1 /dev/hda

/dev/hda:
 setting using_dma to 1 (on)
 HDIO_SET_DMA failed: Operation not permitted
 using_dma=  0 (off)


dmesg returns:

Enabling DMA requires the right driver in the kernel; there is an option
for "Generic PCI DMA support" or similar, which might be worth a try if
you can't find an exact match for your IDE chipset.

What does /proc/pci have to say about your IDE controller? This should
tell you which driver to use - then just recompile, reboot, and you have
DMA...

I did indeed get it up and running, with NAT and firewalling. At present,
the machine is sitting gathering dust as my Alpha can only run GNU/Linux,
and it is handling dial up and security duties. (blasphemous that such a
powerful machine is doing that and seti, but hey...)

OpenBSD firewalling from what I can tell isn't too different. It uses the
familiar ipfw to add rules. I think it uses the same ppp as FreeBSD, which
handles NAT itself. If you are connected to the internet using anything
other than a ppp connection, you should use natd to handle what GNU/Linux
people know as ipmasqing.

I'd say go for it,(Free|Open)BSD are as if not more capable than GNU/Linux
in a majority of circumstances. There are a few differences here and there
from the sysadmins perspective, but overall it is a pleasurable
experience.

Hope that helps, any questions, fire 'em my way.

Not to be the mistress of understatement, but I found a big
difference between double-digit nets (16Mb token ring) and
triple digit nets (220Mb glass).

If possible, as in, Conor is wiring his house himself, I'd
suggest going with 100Mb copper.

uh... DMA is disabled in the BIOS? :)

eg, perhaps you've manually set the disks i9n the bios to PIO only? so
try just setting them to "auto"  or similar, and see what happens.

/proc/pci has this to say...

  Bus  0, device  15, function  0:
IDE interface: Acer Labs M5229 TXpro (rev 193).
  Medium devsel.  Fast back-to-back capable.  Master Capable.
Latency=32.  Min Gnt=2.Max Lat=4.
  I/O at 0xffa0 [0xffa1].

will poke around the kernel and see what I come up with.

Somebody else said something about

###
hda: Maxtor 91021U2, ATA DISK drive
hdb: FUJITSU MPD3084AT, ATA DISK drive 
 

Longshot here, but wasn't there at one stage a fairly serious problem
with these makes of drive interoperating on the same IDE controller?
###

Anyone know anything about that?  I haven't had any issues myself with
these two drives.

[techtalk] Harping on Win 2K

2001-05-20 Thread Scott

Sorry to bring this up, if you are not running Win 2K ignore this.  But I
did some more research on the hack attempt on my home server the other day
and found some interesting articles on a mailing list.  It appears that
even if you have installed the security patches--if you install SP2 you
have to go back and reinstall those patches for the OS and IIS5 as well.

The guy talking about it was able to scan his registry and found that the
security patches he installed pre SP2 were removed.  If you are interested
let me know.

It does come down to what you are most comfortable with.  When I moved
from BSDI to Linux I had a rough time dealing with /home/scott instead or
/usr/var/shell/scott, but I was able to get it over it quickly.

The bottom line is that we support each other and to improve the options
that are available to us.  I respect the BSD family as they have some
great track records.  I support the Linux family as the innovation is
great, the stability is awesome and the fact it just works is tops for me.

[techtalk] PWM grouping windows

Someone mentioned the window manager PWM the other day.  There is an
option in pwm.conf for grouping Netscape.  I was wondering if anyone has
gotten any other applications to group like xterm or gnome-terminal?
I've tried various instances of -
 winprop "Xterm.xterm" {
frame 10
 }
but can't get any of them to work.
Thanks,

You mean 8-core cat5 cabling?  Thet's the plan then all I gotta do is get
100Mbit hubs and NICs.  I somehow doubt that it's that crucial though for
the home environment.

Hmm - can't see a specific driver. Enabling "Generic PCI bus-master DMA
support" and "Use PCI DMA by default when available" (under "Generic PCI
IDE chipset support") should give you DMA, though...

It was I who mentioned PWM but unfortunately I can't help you much with the
configuration - I've only been using it for a few weeks.

I tend not to do much configuration for my tools until I really need it :(

Yes, Cat5 and a 100Mb switch (not a hub) and 100Mb NICs.

Think about the transfer rates on your disks and CDs and then
think about how many machines you're going to have on your
LAN.  The idea is to keep your network from being the slowest
component.  In other words, make sure there is enough network
bandwidth to hand disk I/O and then you're just as limited
by disk I/O rates remotely as you are locally.

That was as your CPU and disks get faster (they always do,
right?) you'll see the performance improvement passed along.
If you start off limited by your LAN things never get faster ...

[techtalk] Star Office - failed to load necessary component

2001-05-20 Thread christina

Hi!

I have a problem with Star Office 5.2 on RedHat 7.1.

Star Office is being installed with the /net option on a local
harddisk. The user's homes get mounted from an HP server via NFS. 

When a new user executes "soffice" for the first time, the user part
of the installation process runs as it should. When the user runs
"soffice" for the first time AFTER the user installation, the program
fails with the error message "failed to load the necessary components". 

I have been told that this message means that the file ~/.user52.rdb
is corrupted and that deleting this file should fix it. At first, this
seemed to work. Star Office started perfectly. But when I tried to
start Star Office for the second time, it showed a Basic error message
and the icons on the desktop were missing. During the following
attempts several other error messages occured.

I've also been told that there are problems with the NFS server that
can cause these errors to happen. I was able to exclude this 
possibility because the server machine is the same as for our RedHat
6.2 machines on which Star Office works perfectly. When a user who has
already been using Star Office on RedHat 6.2 moves to 7.1 with the
configuration files in place Star Office also works on RedHat 7.1.

Sun Microsystems only told me to "please make sure you really use Star
Office 5.2" ... very funny ... especially if you consider that
I wrote that I was using 5.2 serveral times in my message just to make
sure they wouldn't give me their "default answer" :-(

I really would appreciate any help. Has anyone knowledge of the
details of the configuration files Star Office writes to a user's home
directory? Or any other hints? I really don't want to have to tell our
users to boot Win2K and use MS Office when we upgrade to RedHat 7.1 in
the next couple of days :-(

about a patch  I should get for IRC security (kernek
patch) and I'm wondering which kernel needs to be
upgraded for that.  The server is running Caldera 2.4
and kernel 2.2.14.  The client is running Mandrake 8
with the 2.4.3-20mk kernel.  I've got rc.firewall
running on Caldera and the built in Bastille firewall
running on Mandrake.  Is it preventing me from
uploading via DCC in irc because I have two firewalls?
 I'm afraid of turning off my client firewall for fear
the firewall I set up on Caldera isn't very good.

Hi,

just tried PWM ... wow! it's simply great. Up to the very moment I've
been a real fan of wmx [1], but this one seems to be even better!
Thanks Mary for mentioning it :)

As to your grouping problem, Kent, I think it's simply "XTerm.xterm"
(note the capital T) -- at least that works for me. In case of doubt
about a window's class/instance properties, just use xprop(1) (and
look for WM_CLASS).

Not configure, how do you do it;)  I'm really glad you mentioned PWM, I
ditched window maker for it.  It's light and I love the way you can
group at least Netscape and xterm into one window and toggle between
them with keys.  

I finally found this worked for xterm in my setup -
winprop "Xterm.term" {
 frame 1
}

Then start xterm with "-name term" all will be loaded into one frame.

Some other things one might consider are:

-turning off ipforwarding entierely and
running heavily logged proxies instead

-turning off access from TROTW (The Rest
Of The World) to things you need through
hosts.deny/hosts.access rules

-keeping up with bugtraq advisories and
new security patches provided for your distro

-providing physical security and improving
your boundaries against "social engineering"
(otherwise known as learning how to keep a secret)

-coming up with more effective strategies
for dealing with intruders (e.g. honeypots
and off-site logging, doing the diffs auto-
matically, setting alarm levels appropriately, etc)

Perhaps the least effective security measure is
throwing your toys on-list.  It's uh...*pretty* silly.

The closest thing I've seen to an out-of-the-box linux
firewall would be the SuSE "minimal install" followed by
running the hardsuse script.

There is a description of what this does at:

http://portal.suse.de/en/content.php?SEARCH&content/security/secure_webserv.html

And even Marc Heuse recommends OpenBSD for those who aren't
100% satisfied with the measures taken in hardSuSE and, say,
Bastille.

And don't underestimate the power of unplugging your network
from the rest of the world if you have security concerns.

Woohoo, sounds good.

My last wm was windowmaker too (don't like double clicking at all), sawfish on
Helix Gnome before that and fvwm2 before that.

Here's to PWM and key-bindings.

Mary.
