[SLUG] Netcomm Mega I Modem

[Richard Luckhurst]

Hi List

Has anyone had any trouble with Netcomm Mega I
modems used on mgetty ports? A client of mine is finding the
modem  quite often does not rest correctly and wait to answer
an incoming call after the machine is rebooted. He has to cycle
to modem power after the PC is up to get it to work. He is using
quite a few of these and has no other modems on site. I want to 
get a few opinions before I get a hold of another modem and 
drive a few hundred Km out into the boonies to work on the
problem.

Regards

Richard

[SLUG] Switching virtual terminals & X - screen blanks

[steven]

I am running Woody on a VIA Eden.  I selected Trident as the video chipset.

All seems to work well with X untill I switch to another VT eg Ctrl-Alt-F1.
When I try to switch back to X (Ctrl-F7 or Ctrl-Alt-F7) the screen just
blanks.  The power light on the monitor starts to flash which I think
indicates it is getting no signal from the PC.

I thought I had once read something about this but can't find anything now.

Any suggestions.

TIA
Steven

I got this on redhat7.3.  I found my machine running
really sluggish one time, and checked to find logrotate
taking up 90+% cpu.  And the logs directory with 1+
of these blighters.

Never did investigate further ... just upgraded to redhat8.

Generally I've found netcomms to be the best in this setup, however not had
much experience with the modem in question. I use to have a few Netcomm
Smartmodem 33.6 type ones, and these days tend to use the Netcomm Roadster
II 56ultra.

I think you'd explore its AT setup, and its power on config to confirm what
registers are beind used at power on. It might end up leading to solving the
problem by tweaking this config.

I am sure others could give more information on this, however if given
sometime I am sure I could probably find some old notes, which I hope are
still at my parents describing my old configs.

Thanks

PS. While on the subject, anyone want to purchase an old Stallion ISA Easy
IO 8 port serial card with Octopus cable?

Ironically enough I ran a test install and setup of Redhat 7.3 and don't
believe I came across that problem. Might have to install again sometime and
confirm if it happens with a default type install.

for the record this is `unset SESSION_MANAGER` on a specfic command. 
This is my current work around but I was hoping for a cleaner solution
for other non-technical gnomers on the openoffice.org list.

I would love to be able to set it up and down to suit what I am doing. 
I could script it then :-)

As Jeff said one for the gnome list :-(

These are data Minidiscs, which are incompatible with audio.  Not due to
any good reason, just because Sony wanted to charge more for data
blanks.  Duh!

Erm, you want to go from MD -> MD?  You'd need a professional dual deck
(best) or a professional deck which has a digital out (not as good
because it's decompressed then recompressed again).  The other options
is MD -> analogue -> MD.

www.minidisc.org for details of the full range of kit available.

[SLUG] SLUG events list, now in RSS!

[Angus Lees]

I was bored this afternoon and happened to be reminded of the XML::RSS
perl module. So now the SLUG events list is available as an "RDF Site
Summary" for all you ticker people out there:

  http://slug.org.au/events/rss.xml

Currently it duplicates the list given on the SLUG front page
(ie: next 9 events), with links to the event detail page.

The event time is jammed in with the rest of the description. If
there's some markup I could be using to make the event time or event
description clearer, I'm open to suggestions. (I never actually read
the RDF/RSS specs..)

Hi Matt,

The place to buy them wholesale is BCN.

www.bcntech.com.au

They do have a barebones option (i.e. Case + MB), but it can't handle 2 PCI 
and it has more fans than Elvis so we build our own systems...

Re: [SLUG] Funny logrotate behaviour

[scott]

It is a bug with the standard Redhat. 7.3 rpms.
The mgetty file in /etc/logrotate.d contains:
/var/log/mgetty.log.tty*
I guess the reason for this is to rotate the modem logs on all serial 
ports, but it wasn't well thought through.
I just changed mine to /var/log/mgetty.log.ttyS1 (as I only use the one 
serial port), I guess that works

Cheers,

Scott

I've answered a few of these offline as well. There is auspcmarket.com.au as
has been mentioned below, however a mob at Castle Hill known as Programmers
Paradise have them right they way up to the new 933MHz model which has a
funky bios option where it autodetects if there is a dvd movie in the dvd
drive (if present) and will play the dvd without booting the OS. They also
have a couple of micro-ITX cases as well.

If you can help it, don't use raidtools, use mdadm.  Red Hat and Debian
package it, and as Mandrake is so cookery cool I'd bet they've got it too.

mdadm is the sane way to build software raid.

Thanks, checking out mdadm now. Would you take the same route when moving
from no-RAID to RAID with it, or does it have a tricky do-it-all thing?

(Having checked it out, yeah, same method. mdadm is more automatable, but
replaces a nice config file with a somewhat more complex tool. Definitely
worth looking at further.)

The timeout has been extended to 2 minutes in the latest release - we'll be

[SLUG] mail sorting

[James Gregory]

Hi all,

I have once again found myself fiddling with my procmail rules in the
hope that one day they will be smart enough to take over the world. My
current aim (which I don't think procmail can achieve) is to go through
all my messages once a night and move any messages that are older than
(say) a month into the same folders under my "Archives" folder.

Does anyone know how to do this or do I need to write a little perl
script to do it?

Thanks,

James.

G'day Jeff (and all)

I'm going to use raidtools, rather than mdadm (not because its the best, 
but because there is more documentation to ease my learning curve).

Just wanting to check my /etc/raidtab before starting the array. (I'm 
nervous, and really don't want to loose data or incur extra downtime.)

So here it is:

raiddev /dev/md0
raid-level  1
nr-raid-disks   2
nr-spare-disks  0
chunk-size  4
persistent-superblock   1
device  /dev/sda1
raid-disk   0
device  /dev/sda2
raid-disk   1
failed-disk 0

>From my understanding this will set up my two scsi disks, with the first 
one marked as a failed disk (so I can keep its contents currently).

Thanks heaps.

There's a list of readers at http://blogspace.com/rss/readers, not all
are for Linux.

Straw (Python GTK2) is available from: http://www.nongnu.org/straw/

and is also packaged for Debian, available from the usual repositories:
at least unstable. Unfortunately, there don't seem to be RPMs around.

Many of the geek news sites have RSS or RDF files:

Slashdot: http://slashdot.org/slashdot.rdf

Kuro5hin: http://www.kuro5hin.org/backend.rdf

Advogato: http://www.advogato.org/rss/articles.xml

There are some unofficial feeds for Australian media at:
http://axiom.anu.edu.au/rdf (I presume they are parsing the site HTML to
produce those).

Re: [SLUG] Using raid as root filesystem under Mandrake 8.2

[mkraus]

To answer my own question

/dev/sda1 and /dev/sda2 should be set the other way around ie:

raiddev /dev/md0
raid-level  1
nr-raid-disks   2
nr-spare-disks  0
chunk-size  4
persistent-superblock   1
device  /dev/sda2
raid-disk   0
device  /dev/sda1
raid-disk   1
failed-disk 1

according to the HOWTO.

Any additional pointers, reassurance ;) etc appreciated.

While this would be handy, you would need to at least run your mailboxes
through formail to split them up into messages and then pipe them to
procmail, all with a cronjob.

I think scripting is probably a better idea.

[SLUG] pam problem

[Simon Bryan]

Hi all,
I have been having an ongoing minor problem with an application (AUC) that
uses PAM for authentication. AUC has it's own userbase/password, but needs
the users to exist in /etc/password as well (for email). Every time a user
logs in it generates an error in the logs similar to:
Jan  7 13:01:33 vortex PAM_pwdb[30287]: get passwd; pwdb: request not
recognized

the associated pam.d file is:

#%PAM-1.0
auth required   /lib/security/pam_smb_auth.so debug
auth   sufficient   /lib/security/pam_pwdb.so shadow nullok
auth   required /lib/security/pam_nologin.so
accountrequired /lib/security/pam_pwdb.so
password   required /lib/security/pam_pwdb.so not_set_pass nullok
sessionrequired /lib/security/pam_pwdb.so


To fix this issue I have removed debug from line 1 and commented out line 2,
now this seems to work. Can anyone see any 'unintended consequences' of
this? I have been reading on-line about PAM but am still quite hazy, it
seems to me though that line 2 is asking for a password and expecting it to
be in the shadow file, which it isn't and because it is only set at
sufficient things continue.

[SLUG] Further RAID discussions.

[mkraus]

G'day all...

I've got my RAID setup and working with my current root filesystem on the 
failed-disk.

Currently, I've got my primary HD (/dev/sda1) containing a number of 
different partitions - root, home, usr, var, swap, etc.

What would be recommended / suggested here? That I further partition my 
RAID device? If so how should I do this?

As you can guess, I'm new to this.

TIA!

This old info, below, might contain something of use.  Oh, and I had
trouble making an initrd image that works, so I gave up on that, and
just built a kernel with raid support (and ext3 support too, for that
matter) built in, instead of as modules.

 From: [EMAIL PROTECTED]
 Subject: Restoring a RAID mirror
Date: Tue, 12 Nov 2002 21:44:55 +1100 (EST)
  To: Sydney Linux Users Group <[EMAIL PROTECTED]>

Just thought I'd pass on the info below.  Also, if anyone running Red
Hat 8.0 could do a man raidhotadd and let me know whether the program
has a man page or not, I'll know whether or not to submit a bug report
to RH about the missing man page.  (I'm on RH 7.2.)

Recovering a RAID mirror is easy, as it says here
http://www.kieser.net/linux/raidhotadd.html or here
http://www-106.ibm.com/developerworks/linux/library/l-raid2/index.html

Basically, if you cat /proc/mdstat and see stuff like 

md2 : active raid1 hda7[0]
  29567488 blocks [2/1] [U_]

The U_ means only 1 volume is up (active), the other is down, and the
raid is running in degraded mode.  If you dmesg | more you'll find
messages to that effect.

Once you've sorted out the problem that lead to the partition from being
dropped from the raid array in the first place, then you use raidhotadd
to copy the good data from the active volume onto the other, on a
running system.  You can even cat /proc/mdstat to see the recovery 
progress.

You use /proc/mdstat and/or dmesg to work out what partition is out of
date.  Check that by looking at /etc/raidtab too.  In my case /dev/hde6
(the root partition on /dev/md0) and /dev/hde7 (/home on /dev/md2) need
to be brought back into the raid set.  Make sure the old or new
partition is big enough.  Ideally it should be the same size as the
working volume.

So, in my case I simply do this:

# /sbin/raidhotadd /dev/md0 /dev/hde6
# /sbin/raidhotadd /dev/md2 /dev/hde7

Being cautious, I watched /proc/mdstat until the first rebuild finished
before starting the second one.  But that's just me being careful.

# cat /proc/mdstat
Personalities : [raid1] 
read_ahead 1024 sectors
md0 : active raid1 hde6[1] hda6[0]
  3076352 blocks [2/2] [UU]
  
md2 : active raid1 hde7[2] hda7[0]
  29567488 blocks [2/1] [U_]
  [>]  recovery =  0.2% (70060/29567488) finish=49.0min 
speed=10008K/sec
unused devices: 

Easy as pie!

Also, since replacing motherboard, CPU, and memory, the system has been
3 days without a crash.  It's starting to feel like a normal Linux
system again.  Soon, I'll try running X11 in 1600x1200 mode again.

[SLUG] mgp presentations from components

[Bruce Badger]

I'm working with Magic Point (mgp) to put together a number of 
presentations.  These presentations have much in common, so I want to be 
able to form a presentation from a number of sub-components.  I thought 
I could use the $include directive in .mgp files to suck the component 
files into one big presentation, but $include is a one-shot thing for 
establishing defaults :-(  So, it seems that there is no built-in way of 
doing this in mgp.  How, then, can I do what I want?

I guess if i could have a file like "next-tuesday-talk.mgp.spec" that 
looked like:
   $include 'common-header.mgp'
   $include 'funny-story-1.mgp'
   $include 'technical-bit-1.mgp'
   ...etc...

... and have a script to bolt it all together to make 
"next-tuesday-talk.mgp'.  Is there any tool around that will just do 
this kind of thing, or do I need to write my own script?

Sorry, that was a long way of asking something that I'm sure is very simple.

Thanks,
   Bruce

There are a few different schools of thought.  I belong to the school
that recommends a small number of partitions, like this:

/   About 4Gb, big enough to hold a full modern Linux distro.
including root, usr, var.

swapAs big as you need.  I've always run with a swap partition of
about 100Mb - which is often smaller than physical RAM.  This
goes against the accepted wisdom, because I feel that the system
becomes unusable quite quickly once the machine becomes swapping
very much.

/spare  Big enough to hold a whole new Linux distro!

/home   The rest of the drive, especially if you make /usr/local just a
symbolic link to somewhere there.

/C: Often you may have a legacy OS partition, too.  :-)

This arrangement makes it very easy to upgrade from one version of the
OS to another - especially if you have a /spare so you can try the new
OS out and gradually settle in.

I find that if you partition too finely, you can never predict how big
each partition really should be, so you either waste a lot of space by
making each partition much bigger than it needs to be, or else you end
up with each `optimally' sized partition running out of space over the
years, and having to resize them.

Keep it simple, basically.

If you have a sudden problem of some sort that causes lots of logging
(say nimda attacking (and failing to hurt) your apache install) a
separate /var will save your life.

Also splitting out /usr/local can help during upgrades.

I'm from the old school (when disks were small and expensive) and
usually use :
/
/usr
/usr/local
/var
/home

Then, depending on the function of the machine, put spool files,
docroots etc on a seperate spindle.

Agreed.  But there's no reason to put it on a partition all its own,
and risk the problems I mentioned earlier.  Just let it use some of the
/home partition:

mv /usr/local /home; ln -s /home/local /usr/local

Sounds like a job for m4!  Well, it sounds like a job for cpp, chpp,
perl, python, or whatever your favourite scripting language happens to
be.  But today I chose m4. :-)

At it's simplest, next-tuesday-talk.mgp.m4 would be something like:
include(common-header.mgp)
include(funny-story-1.mgp)
include(technical-bit-1.mgp)
include(blah)

But there's nothing stopping you from creating a talk-header.m4 with
macros for all your files, like:
include(common-header.mgp)
define(FUNNY-STORY-1 `/path/to/funny-story-1.mgp')dnl

then include that in your talk file, and use commands like
include(FUNNY-STORY-1)

You can stick macros in the.mgp files themselves as well, say to include
the current date.

The info manual for m4 is fairly thorough as far as syntax.  I'm sure
google will find tutorials that are much more legible than my effort.

m4 is good for much more than just sendmail configs!

plenty of tools around.

cpp (or "gcc -E") is one you might already be familiar with:

 #include "common-header.mgp"
 #include "funny-story-1.mgp"
 #include "technical-bit-1.mgp

 %  cpp next-tuesday-talk.mgp.spec next-tuesday-talk.mgp

you may have problems with extra blank lines and "#line 75" directives
inserted in the output.  iirc, mgp will see these as harmless comments
and they will probably be very useful to your debugging, but you can
use -P to turn them off.


one of the more generic and powerful tools around is probably m4 (as
used by autoconf to generate configure.in for example), but it can
take a bit of getting used to if you wish:

 include(`common-header.mgp')
 include(`funny-story-1.mgp')
 include(`technical-bit-1.mgp')

 %  m4 next-tuesday-talk.mgp.spec > next-tuesday-talk.mgp

if the quoting characters conflict with your normal text too often,
one of the first things you may want to do is redefine them (autoconf
sets them to [ and ]) - see m4 docs.


both of these tools will also allow substitutions and conditionals. m4
even allows you to define fairly complex functions.


almost any talk i give that has more than one source file, has a
Makefile to help me avoid typing (and remember command lines). you
might want to consider doing the same.

Yes, that's the case. 1 RAID device == 1 partition.

You may however get really tech and use LVM (Linux Volume Management)
from Sistina.com and make logical volumes on your RAID Device. These
Logical partitions act like 'normal' partitions but with the added bonus
of being able to grow/shrink your partitions.

You can add more disk space to the Logical Volume group and your system
will treat the larger logical volume as if it was just one larger disk.

I haven't ever used the LVM, I have just been reading about it lately.

It sounds like you set things up for msdos, then installed Linux, then
Win 98?

I believe 98 rewrites the master boot record as part of the
installation.

Normally you'd install 98 then Linux, for that reason.   It's no big
deal, though, Linux should still be there, just unreachable at boot
time.

You need to rewrite the MBR with something that can let you pick which
OS you want to boot (e.g. Lilo).

You need to somehow boot up some version of Linux.  E.g. from a floppy,
or from your Red Hat installation CDs.  (Don't start the full install
again, though!  It has some rescue mode, from memory: you can boot it
up, and choose rescue, and then do Ctrl-Alt-F2 or -F3, ... to find a
plain super-user `#' prompt.)

Once you've done that, you can mount your installed Linux partition,
and rewrite the MBR with LILO, for example.  You need to know the Linux
device name of the installed Linux partition (the "/" or root
partition).

You can use Linux /sbin/fdisk to print out the partition table, which
will give you the device name for the Linux root partition.  E.g:

/sbin/fdisk /dev/hda
p
l
q

"p" prints the partition table.  "l" lists the partition types:  83 is
Linux.  You may already remember what partition you chose for the "/"
partition, in which case you don't need to use fdisk to find it out.

Anyway, let's say it's /dev/hda4.

So you'd:

#   mount /dev/hda4 /mnt# Make your installed Linux visible.
#   cd /mnt # Go to your installed Linux.
#   chroot /mnt /bin/sh # Start using your installed Linux
#   /sbin/lilo  # Set the MBR to use your installed Linux

/sbin/lilo reads your /etc/lilo.conf file, which should look something
like this:

# Run /sbin/lilo after editing this.
#
prompt
timeout=1200
boot=/dev/hda
default=linux

image=/boot/vmlinuz-2.4.20
label=linux
read-only
root=/dev/hda4

other=/dev/hda1
optional
label=win98

If the /sbin/lilo command completes successfully, all you should then
need to do is reboot.

I think you have to work from existing partitions.  So, if you really
need to split it, then use a tool like Partition Magic (very mature
and safe, but runs under Windows), or GNU parted (I think).

Otherwise you'd have to back up, and re-run fdisk to wipe out and
re-partition, and then mkfs to put the file system back, and then
restore the data from backups, then edit /etc/raidtab and finally use
raidtools to mirror the data onto the new raid partitions.

It may be too big a change for you, but I like the MH way
of storing mail -- one file for each message.  Then doing
things like archiving old mail or deleting all mail which
contains some phrase or header or whatever becomes very easy.

Sylpheed is an excellent gtk gui mail client which supports this

[SLUG] Snapshot-style backups with rsync using hard links

[Gonzalo Servat]

Hi All.

I'm currently testing out backing up data to a removeable medium by using 
rsync & hard links (http://www.mikerubel.org/computers/rsync_snapshots was 
good reading material) and while I'm very happy with the fact that it 
doesn't require more disk space than a bit extra on top of the total amount 
of the data that needs to be backed up (plus it's fully automated), I just 
realised that if a file corrupts itself, unless someone told me about it 
before an rsync took place so I can restore it, it would corrupt the entire 
tree of hard links to the file, right?

Can anyone think of a work around to this problem? (other than backing up 
the backup server to another box :))

Thanks in advance.

Regards,
Gonzalo.

Ahr, I've been using a very similar system on my backup products for a few
months now; the author explains how it works very well.

Not if you're doing rolling snapshots. Then you can just fall back to the
latest uncorrupted snapshot (as you would with any incremental backup
system).

I don't quite get what you mean by the 'entire tree of hard links' - if just
one file is corrupted and backed up, then just that one file will be
corrupted.

Note that as handy-dandy and clever this solution is, it is *NOT* a
replacement for responsible care with off-site backups (physical or
network). If you put a bullet in the disk, you are still stuffed.

I use Maildirs already. That still sounds like a script though :)

And I'd probably use some library rather than parse the headers
directly, so it wouldn't be much different using a Maildir library to a
mbox library.

[SLUG] Long delays in sendmail

[Howard Lowndes]

For some inexplicable reason my sendmail server has suddenly taken to 
taking an inordinately long time (like, minutes) before it returns the 
sendmail banner to start a session.

The initial SYN, SYN/ACK, ACK handshake occurs OK, but then there is a 
lnnng delay before I get the welcome banner.

It's weird as I haven't touched anything - swear...

[SLUG] Long delays in sendmail

[Howard Lowndes]

I discovered that sendmail was taking a long (as in minutes) time to send
the startup banner.  The SYN, SYN/ACK, ACK handshake went OK but then a
long delay before the banner appeared.

It seems that rbl.osirusoft.com is off the air and that is causing 
problems so I have taken it out of sendmail.cf

Just thought you might like to know.

Re: [SLUG] dual boot problem

[Richard Neal]

What happens if you install windows after you have installed Linux it
copies over the mbr.

What you have to do is use the Linux boot disk you made when you
installed Linux boot into Linux and reinstall Grub/Lilo into the mbr..

to reinstall grub type as root

>/usr/sbin/grub-install or just >grub-install

to reinstall lilo type
>lilo
you might need to edit the config files for either but I doubt it

PS method for installing windows and Linux (for me anyway) is

1.Partition hardisk (you don't have to break up the Linux partition the
installer will do this)

2 Install windows

3 Install Linux
